• Migrating SQL Server Databases – The DBA’s Checklist (Part 3)

  - by Sadequl Hussain

  Continuing from Part 2 of the Database Migration Checklist series: Step 10: Full-text catalogs and full-text indexing This is one area of SQL Server where people do not seem to take notice unless something goes wrong. Full-text functionality is a specialised area in database application development and is not usually implemented in your everyday OLTP systems. Nevertheless, if you are migrating a database that uses full-text indexing on one or more tables, you need to be aware a few points. First of all, SQL Server 2005 now allows full-text catalog files to be restored or attached along with the rest of the database. However, after migration, if you are unable to look at the properties of any full-text catalogs, you are probably better off dropping and recreating it. You may also get the following error messages along the way: Msg 9954, Level 16, State 2, Line 1 The Full-Text Service (msftesql) is disabled. The system administrator must enable this service. This basically means full text service is not running (disabled or stopped) in the destination instance. You will need to start it from the Configuration Manager. Similarly, if you get the following message, you will also need to drop and recreate the catalog and populate it. Msg 7624, Level 16, State 1, Line 1 Full-text catalog ‘catalog_name‘ is in an unusable state. Drop and re-create this full-text catalog. A full population of full-text indexes can be a time and resource intensive operation. Obviously you will want to schedule it for low usage hours if the database is restored in an existing production server. Also, bear in mind that any scheduled job that existed in the source server for populating the full text catalog (e.g. nightly process for incremental update) will need to be re-created in the destination. Step 11: Database collation considerations Another sticky area to consider during a migration is the collation setting. Ideally you would want to restore or attach the database in a SQL Server instance with the same collation. Although not used commonly, SQL Server allows you to change a database’s collation by using the ALTER DATABASE command: ALTER DATABASE database_name COLLATE collation_name You should not be using this command for no reason as it can get really dangerous.  When you change the database collation, it does not change the collation of the existing user table columns.  However the columns of every new table, every new UDT and subsequently created variables or parameters in code will use the new setting. The collation of every char, nchar, varchar, nvarchar, text or ntext field of the system tables will also be changed. Stored procedure and function parameters will be changed to the new collation and finally, every character-based system data type and user defined data types will also be affected. And the change may not be successful either if there are dependent objects involved. You may get one or multiple messages like the following: Cannot ALTER ‘object_name‘ because it is being referenced by object ‘dependent_object_name‘. That is why it is important to test and check for collation related issues. Collation also affects queries that use comparisons of character-based data.  If errors arise due to two sides of a comparison being in different collation orders, the COLLATE keyword can be used to cast one side to the same collation as the other.

• Creating and using VM Groups in VirtualBox

  - by Fat Bloke

  With VirtualBox 4.2 we introduced the Groups feature which allows you to organize and manage your guest virtual machines collectively, rather than individually. Groups are quite a powerful concept and there are a few nice features you may not have discovered yet, so here's a bit more information about groups, and how they can be used.... Creating a group Groups are just ad hoc collections of virtual machines and there are several ways of creating a group: In the VirtualBox Manager GUI: Drag one VM onto another to create a group of those 2 VMs. You can then drag and drop more VMs into that group; Select multiple VMs (using Ctrl or Shift and click) then  select the menu: Machine...Group; or   press Cmd+U (Mac), or Ctrl+U(Windows); or right-click the multiple selection and choose Group, like this: From the command line: Group membership is an attribute of the vm so you can modify the vm to belong in a group. For example, to put the vm "Ubuntu" into the group "TestGroup" run this command: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup" Deleting a Group Groups can be deleted by removing a group attribute from all the VMs that constitute that group. To do this via the command-line the syntax is: VBoxManage modifyvm "Ubuntu" --groups "" In the VirtualBox Manager, this is more easily done by right-clicking on a group header and selecting "Ungroup", like this: Multiple Groups Now that we understand that Groups are just attributes of VMs, it can be seen that VMs can exist in multiple groups, for example, doing this: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup","/ProjectX","/ProjectY" Results in: Or via the VirtualBox Manager, you can drag VMs while pressing the Alt key (Mac) or Ctrl (other platforms). Nested Groups Just like you can drag VMs around in the VirtualBox Manager, you can also drag whole groups around. And dropping a group within a group creates a nested group. Via the command-line, nested groups are specified using a path-like syntax, like this: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup/Linux" ...which creates a sub-group and puts the VM in it. Navigating Groups In the VirtualBox Manager, Groups can be collapsed and expanded by clicking on the carat to the left in the Group Header. But you can also Enter and Leave groups too, either by using the right-arrow/left-arrow keys, or by clicking on the carat on the right hand side of the Group Header, like this: . ..leading to a view of just the Group contents. You can Leave or return to the parent in the same way. Don't worry if you are imprecise with your clicking, you can use a double click on the entire right half of the Group Header to Enter a group, and the left half to Leave a group. Double-clicking on the left half when you're at the top will roll-up or collapse the group.   Group Operations The real power of Groups is not simply in arranging them prettily in the Manager. Rather it is about performing collective operations on them, once you have grouped them appropriately. For example, let's say that you are working on a project (Project X) where you have a solution stack of: Database VM, Middleware/App VM, and  a couple of client VMs which you use to test your app. With VM Groups you can start the whole stack with one operation. Select the Group Header, and choose Start: The full list of operations that may be performed on Groups are: Start Starts from any state (boot or resume) Start VMs in headless mode (hold Shift while starting) Pause Reset Close Save state Send Shutdown signal Poweroff Discard saved state Show in filesystem Sort Conclusion Hopefully we've shown that the introduction of VM Groups not only makes Oracle VM VirtualBox pretty, but pretty powerful too.  - FB

• Page output caching for dynamic web applications

  - by Mike Ellis

  I am currently working on a web application where the user steps (forward or back) through a series of pages with "Next" and "Previous" buttons, entering data until they reach a page with the "Finish" button. Until finished, all data is stored in Session state, then sent to the mainframe database via web services at the end of the process. Some of the pages display data from previous pages in order to collect additional information. These pages can never be cached because they are different for every user. For pages that don't display this dynamic data, they can be cached, but only the first time they load. After that, the data that was previously entered needs to be displayed. This requires Page_Load to fire, which means the page can't be cached at that point. A couple of weeks ago, I knew almost nothing about implementing page caching. Now I still don't know much, but I know a little bit, and here is the solution that I developed with the help of others on my team and a lot of reading and trial-and-error. We have a base page class defined from which all pages inherit. In this class I have defined a method that sets the caching settings programmatically. For pages that can be cached, they call this base page method in their Page_Load event within a if(!IsPostBack) block, which ensures that only the page itself gets cached, not the data on the page. if(!IsPostBack) {     ...     SetCacheSettings();     ... } protected void SetCacheSettings() {     Response.Cache.AddValidationCallback(new HttpCacheValidateHandler(Validate), null);     Response.Cache.SetExpires(DateTime.Now.AddHours(1));     Response.Cache.SetSlidingExpiration(true);     Response.Cache.SetValidUntilExpires(true);     Response.Cache.SetCacheability(HttpCacheability.ServerAndNoCache); } The AddValidationCallback sets up an HttpCacheValidateHandler method called Validate which runs logic when a cached page is requested. The Validate method signature is standard for this method type. public static void Validate(HttpContext context, Object data, ref HttpValidationStatus status) {     string visited = context.Request.QueryString["v"];     if (visited != null && "1".Equals(visited))     {         status = HttpValidationStatus.IgnoreThisRequest; //force a page load     }     else     {         status = HttpValidationStatus.Valid; //load from cache     } } I am using the HttpValidationStatus values IgnoreThisRequest or Valid which forces the Page_Load event method to run or allows the page to load from cache, respectively. Which one is set depends on the value in the querystring. The value in the querystring is set up on each page in the "Next" and "Previous" button click event methods based on whether the page that the button click is taking the user to has any data on it or not. bool hasData = HasPageBeenVisited(url); if (hasData) {     url += VISITED; } Response.Redirect(url); The HasPageBeenVisited method determines whether the destination page has any data on it by checking one of its required data fields. (I won't include it here because it is very system-dependent.) VISITED is a string constant containing "?v=1" and gets appended to the url if the destination page has been visited. The reason this logic is within the "Next" and "Previous" button click event methods is because 1) the Validate method is static which doesn't allow it to access non-static data such as the data fields for a particular page, and 2) at the time at which the Validate method runs, either the data has not yet been deserialized from Session state or is not available (different AppDomain?) because anytime I accessed the Session state information from the Validate method, it was always empty.

• Get to Know a Candidate (9 of 25): Gary Johnson&ndash;Libertarian Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Johnson served as the 29th Governor of New Mexico from 1995 to 2003, as a member of the Republican Party, and is known for his low-tax libertarian views and his strong emphasis on personal health and fitness. While a student at the University of New Mexico in 1974, Johnson sustained himself financially by working as a door-to-door handyman. In 1976 he founded Big J Enterprises, which grew from this one-person venture to become one of New Mexico's largest construction companies. He entered politics for the first time by running for Governor of New Mexico in 1994 on a fiscally conservative, low-tax, anti-crime platform. Johnson won the Republican Party of New Mexico's gubernatorial nomination, and defeated incumbent Democratic governor Bruce King by 50% to 40%. He cut the 10% annual growth in the budget: in part, due to his use of the gubernatorial veto 200 times during his first six months in office, which gained him the nickname "Governor Veto". Johnson sought re-election in 1998, winning by 55% to 45%. In his second term, he concentrated on the issue of school voucher reforms, as well as campaigning for marijuana decriminalization and opposition to the War on Drugs. During his tenure as governor, Johnson adhered to a stringent anti-tax and anti-bureaucracy policy driven by a cost–benefit analysis rationale, setting state and national records for his use of veto powers: more than the other 49 contemporary governors put together. Term-limited, Johnson could not run for re-election at the end of his second term. As a fitness enthusiast, Johnson has taken part in several Ironman Triathlons, and he climbed Mount Everest in May 2003. After leaving office, Johnson founded the non-profit Our America Initiative in 2009, a political advocacy committee seeking to promote policies such as free enterprise, foreign non-interventionism, limited government and privatization. The Libertarian Party is the third largest political party in the United States. It is also identified by many as the fastest growing political party in the United States. The political platform of the Libertarian Party reflects the ideas of libertarianism, favoring minimally regulated markets, a less powerful state, strong civil liberties (including support for Same-sex marriage and other LGBT rights), cannabis legalization and regulation, separation of church and state, open immigration, non-interventionism and neutrality in diplomatic relations (i.e., avoiding foreign military or economic entanglements with other nations), freedom of trade and travel to all foreign countries, and a more responsive and direct democracy. Members of the Libertarian Party have also supported the repeal of NAFTA, CAFTA, and similar trade agreements, as well as the United States' exit from the United Nations, WTO, and NATO. Although there is not an officially labeled political position of the party, it is considered by many to be more right-wing than the Democratic Party but more left-wing than the Republican Party when comparing the parties' positions to each other, placing it at or above the center. In the 30 states where voters can register by party, there are over 282,000 voters registered as Libertarians. Hundreds of Libertarian candidates have been elected or appointed to public office, and thousands have run for office under the Libertarian banner. The Libertarian Party has many firsts in its credit, such as being the first party to get an electoral vote for a woman in a United States presidential election. Learn more about Gary Johnson and Libertarian Party on Wikipedia.

• F# and the rose-tinted reflection

  - by CliveT

  We're already seeing increasing use of many cores on client desktops. It is a change that has been long predicted. It is not just a change in architecture, but our notions of efficiency in a program. No longer can we focus on the asymptotic complexity of an algorithm by counting the steps that a single core processor would take to execute it. Instead we'll soon be more concerned about the scalability of the algorithm and how well we can increase the performance as we increase the number of cores. This may even lead us to throw away our most efficient algorithms, and switch to less efficient algorithms that scale better. We might even be willing to waste cycles in order to speculatively execute at the algorithm rather than the hardware level. State is the big headache in this parallel world. At the hardware level, main memory doesn't necessarily contain the definitive value corresponding to a particular address. An update to a location might still be held in a CPU's local cache and it might be some time before the value gets propagated. To get the latest value, and the notion of "latest" takes a lot of defining in this world of rapidly mutating state, the CPUs may well need to communicate to decide who has the definitive value of a particular address in order to avoid lost updates. At the user program level, this means programmers will need to lock objects before modifying them, or attempt to avoid the overhead of locking by understanding the memory models at a very deep level. I think it's this need to avoid statefulness that has led to the recent resurgence of interest in functional languages. In the 1980s, functional languages started getting traction when research was carried out into how programs in such languages could be auto-parallelised. Sadly, the impracticality of some of the languages, the overheads of communication during this parallel execution, and rapid improvements in compiler technology on stock hardware meant that the functional languages fell by the wayside. The one thing that these languages were good at was getting rid of implicit state, and this single idea seems like a solution to the problems we are going to face in the coming years. Whether these languages will catch on is hard to predict. The mindset for writing a program in a functional language is really very different from the way that object-oriented problem decomposition happens - one has to focus on the verbs instead of the nouns, which takes some getting used to. There are a number of hybrid functional/object languages that have been becoming more popular in recent times. These half-way houses make it easy to use functional ideas for some parts of the program while still allowing access to the underlying object-focused platform without a great deal of impedance mismatch. One example is F# running on the CLR which, in Visual Studio 2010, has because a first class member of the pack. Inside Visual Studio 2010, the tooling for F# has improved to the point where it is easy to set breakpoints and watch values change while debugging at the source level. In my opinion, it is the tooling support that will enable the widespread adoption of functional languages - without this support, people will put off any transition into the functional world for as long as they possibly can. Without tool support it will make it hard to learn these languages. One tool that doesn't currently support F# is Reflector. The idea of decompiling IL to a functional language is daunting, but F# is potentially so important I couldn't dismiss the idea. As I'm currently developing Reflector 6.5, I thought it wise to take four days just to see how far I could get in doing so, even if it achieved little more than to be clearer on how much was possible, and how long it might take. You can read what happened here, and of the insights it gave us on ways to improve the tool.

• Android - passing data between Activities

  - by Bill Osuch

  (To follow along with this, you should understand the basics of starting new activities: Link ) The easiest way to pass data from one activity to another is to create your own custom bundle and pass it to your new class. First, create two new activities called Search and SearchResults (make sure you add the second one you create to the AndroidManifest.xml file!), and create xml layout files for each. Search's file should look like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <TextView          android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:text="Name:"/>     <EditText                android:id="@+id/edittext"         android:layout_width="fill_parent"         android:layout_height="wrap_content"/>     <TextView          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="ID Number:"/>     <EditText                android:id="@+id/edittext2"                android:layout_width="fill_parent"                android:layout_height="wrap_content"/>     <Button           android:id="@+id/btnSearch"          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="Search" /> </LinearLayout> and SearchResult's should look like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <TextView          android:id="@+id/txtName"         android:layout_width="fill_parent"         android:layout_height="wrap_content"/>     <TextView          android:id="@+id/txtState"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="No data"/> </LinearLayout> Next, we'll override the OnCreate method of Search: @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.search);     Button search = (Button) findViewById(R.id.btnSearch);     search.setOnClickListener(new View.OnClickListener() {         public void onClick(View view) {                           Intent intent = new Intent(Search.this, SearchResults.class);              Bundle b = new Bundle();                           EditText txt1 = (EditText) findViewById(R.id.edittext);             EditText txt2 = (EditText) findViewById(R.id.edittext2);                                      b.putString("name", txt1.getText().toString());             b.putInt("state", Integer.parseInt(txt2.getText().toString()));                              //Add the set of extended data to the intent and start it             intent.putExtras(b);             startActivity(intent);          }     }); } This is very similar to the previous example, except here we're creating our own bundle, adding some key/value pairs to it, and adding it to the intent. Now, to retrieve the data, we just need to grab the Bundle that was passed to the new Activity and extract our values from it: @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.search_results);     Bundle b = getIntent().getExtras();     int value = b.getInt("state", 0);     String name = b.getString("name");             TextView vw1 = (TextView) findViewById(R.id.txtName);     TextView vw2 = (TextView) findViewById(R.id.txtState);             vw1.setText("Name: " + name);     vw2.setText("State: " + String.valueOf(value)); }

• Monitor SQL Server Replication Jobs

  - by Yaniv Etrogi

  The Replication infrastructure in SQL Server is implemented using SQL Server Agent to execute the various components involved in the form of a job (e.g. LogReader agent job, Distribution agent job, Merge agent job) SQL Server jobs execute a binary executable file which is basically C++ code. You can download all the scripts for this article here SQL Server Job Schedules By default each of job has only one schedule that is set to Start automatically when SQL Server Agent starts. This schedule ensures that when ever the SQL Server Agent service is started all the replication components are also put into action. This is OK and makes sense but there is one problem with this default configuration that needs improvement  -  if for any reason one of the components fails it remains down in a stopped state.   Unless you monitor the status of each component you will typically get to know about such a failure from a customer complaint as a result of missing data or data that is not up to date at the subscriber level. Furthermore, having any of these components in a stopped state can lead to more severe problems if not corrected within a short time. The action required to improve on this default settings is in fact very simple. Adding a second schedule that is set as a Daily Reoccurring schedule which runs every 1 minute does the trick. SQL Server Agent’s scheduler module knows how to handle overlapping schedules so if the job is already being executed by another schedule it will not get executed again at the same time. So, in the event of a failure the failed job remains down for at most 60 seconds. Many DBAs are not aware of this capability and so search for more complex solutions such as having an additional dedicated job running an external code in VBS or another scripting language that detects replication jobs in a stopped state and starts them but there is no need to seek such external solutions when what is needed can be accomplished by T-SQL code. SQL Server Jobs Status In addition to the 1 minute schedule we also want to ensure that key components in the replication are enabled so I can search for those components by their Category, and set their status to enabled in case they are disabled, by executing the stored procedure MonitorEnableReplicationAgents. The jobs that I typically have handled are listed below but you may want to extend this, so below is the query to return all jobs along with their category. SELECT category_id, name FROM msdb.dbo.syscategories ORDER BY category_id; Distribution Cleanup LogReader Agent Distribution Agent Snapshot Agent Jobs By default when a publication is created, a snapshot agent job also gets created with a daily schedule. I see more organizations where the snapshot agent job does not need to be executed automatically by the SQL Server Agent  scheduler than organizations who   need a new snapshot generated automatically. To assure this setting is in place I created the stored procedure MonitorSnapshotAgentsSchedules which disables snapshot agent jobs and also deletes the job schedule. It is worth mentioning that when the publication property immediate_sync is turned off then the snapshot files are not created when the Snapshot agent is executed by the job. You control this property when the publication is created with a parameter called @immediate_sync passed to sp_addpublication and for an existing publication you can use sp_changepublication. Implementation The scripts assume the existence of a database named PerfDB. Steps: Run the scripts to create the stored procedures in the PerfDB database. Create a job that executes the stored procedures every hour. -- Verify that the 1_Minute schedule exists. EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 13; /* LogReader */ -- Verify all replication agents are enabled. EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 13; /* LogReader */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 11; /* Distribution clean up */ -- Verify that Snapshot agents are disabled and have no schedule EXEC PerfDB.dbo.MonitorSnapshotAgentsSchedules; Want to read more of about replication?

• Wireless is detected, but not connecting. Ethernet works. How to correct the wireless address?

  - by Lucas

  I am running Ubuntu 14.04 with cable internet, and my wireless is detected and connected, but I cannot connect to the internet. I know the problem is with my machine because other machines are connecting to the same router just fine. I can connect via ethernet just fine as well. Here are some notable tests: ping 192.168.0.105 works with 0% packet loss, but ping 192.168.0.1 has 100% packet loss. When I plug in my ethernet, ping 192.168.0.1 works with 0% packet loss. My wireless name is tg, and the router ip is 192.168.0.1 (where I can enter username and password). I suspect that I need to change my wireless address from 192.168.0.105 to 192.168.0.1. Any suggestions on how to proceed? extra info: [lucas@lucas-ThinkPad-W520]/home/lucas$ iwconfig eth0 no wireless extensions. lo no wireless extensions. wlan0 IEEE 802.11abgn ESSID:"tg" Mode:Managed Frequency:2.462 GHz Access Point: 00:02:6F:83:F8:F4 Bit Rate=1 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=62/70 Signal level=-48 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:52 Invalid misc:166 Missed beacon:0 [lucas@lucas-ThinkPad-W520]/home/lucas$ ifconfig eth0 Link encap:Ethernet HWaddr f0:de:f1:b2:53:53 inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::f2de:f1ff:feb2:5353/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:980003 errors:0 dropped:0 overruns:0 frame:0 TX packets:498384 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1320506168 (1.3 GB) TX bytes:59780591 (59.7 MB) Interrupt:20 Memory:f3a00000-f3a20000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:21927 errors:0 dropped:0 overruns:0 frame:0 TX packets:21927 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1781719 (1.7 MB) TX bytes:1781719 (1.7 MB) wlan0 Link encap:Ethernet HWaddr 24:77:03:29:8f:dc inet addr:192.168.0.105 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::2677:3ff:fe29:8fdc/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:11828 errors:0 dropped:0 overruns:0 frame:0 TX packets:15444 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4855662 (4.8 MB) TX bytes:2250585 (2.2 MB) [lucas@lucas-ThinkPad-W520]/home/lucas$ lspci -nn | grep 0280 03:00.0 Network controller [0280]: Intel Corporation Centrino Ultimate-N 6300 [8086:4238] (rev 3e) [lucas@lucas-ThinkPad-W520]/home/lucas$ rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: tpacpi_bluetooth_sw: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no with ethernet unplugged: [lucas@lucas-ThinkPad-W520]/home/lucas$ route -n | grep UG 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0 with ethernet plugged in: [lucas@lucas-ThinkPad-W520]/home/lucas$ route -n | grep UG 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 [lucas@lucas-ThinkPad-W520]/home/lucas$ nm-tool NetworkManager Tool State: connected (global) - Device: wlan0 [tg] ---------------------------------------------------------- Type: 802.11 WiFi Driver: iwlwifi State: connected Default: no HW Address: 24:77:03:29:8F:DC Capabilities: Speed: 52 Mb/s Wireless Properties WEP Encryption: yes WPA Encryption: yes WPA2 Encryption: yes Wireless Access Points (* = current AP) tatum: Infra, 40:8B:07:D8:A5:04, Freq 2437 MHz, Rate 54 Mb/s, Strength 42 W PA WPA2 ums: Infra, 00:20:A6:72:52:BF, Freq 2437 MHz, Rate 54 Mb/s, Strength 59 Alpha 40: Infra, 28:CF:E9:86:59:5D, Freq 5260 MHz, Rate 54 Mb/s, Strength 30 W PA WPA2 thepromiselan: Infra, 58:6D:8F:51:E5:54, Freq 2452 MHz, Rate 54 Mb/s, Strength 34 $ PA WPA2 xfinitywifi: Infra, 06:1D:D5:84:27:A0, Freq 2437 MHz, Rate 54 Mb/s, Strength 52 *tg: Infra, 00:02:6F:83:F8:F4, Freq 2462 MHz, Rate 54 Mb/s, Strength 73 W PA2 ums: Infra, 00:20:A6:A1:9F:25, Freq 2452 MHz, Rate 54 Mb/s, Strength 44 BRIAN-PC_Network:Infra, 20:AA:4B:DD:93:D6, Freq 2462 MHz, Rate 54 Mb/s, Strength 35 W PA2 HOME-C0F8: Infra, 44:32:C8:D2:C0:F8, Freq 2412 MHz, Rate 54 Mb/s, Strength 40 W PA WPA2 abcsexy: Infra, 28:28:5D:27:5D:85, Freq 2412 MHz, Rate 54 Mb/s, Strength 27 W PA WPA2 IPv4 Settings: Address: 192.168.0.105 Prefix: 24 (255.255.255.0) Gateway: 192.168.0.1 DNS: 192.168.0.1 - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: e1000e State: connected Default: yes HW Address: F0:DE:F1:B2:53:53 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.0.100 Prefix: 24 (255.255.255.0) Gateway: 192.168.0.1 DNS: 192.168.0.1

• 65536% Autogrowth!

  - by Tara Kizer

  Twice a year, we move our production systems to our disaster recovery site.  Last Saturday night was one of those days.  There are about 50 SQL Server databases to be moved to the DR site, which is done via database mirroring.  It takes only a few seconds to failover, but some databases have a bit more involved work such as setting up replication.  Everything went relatively smooth, but we encountered a weird bug on our most mission critical system.  After everything was successfully failed over to the DR site, it was noticed that mirroring was in a suspended state on one of the databases.  We thought we had run into a SQL Server 2005 bug that we had been encountering and were working with Microsoft on a fix.  Microsoft did fix it in both SQL Server 2005 service pack 3 cumulative update package 13 and service pack 4 cumulative update package 2, however SP3 CU13 and SP4 both recently failed on this system so we were not patched yet with the bug fix.  As the suspended state was causing us issues with replication, we dropped mirroring.  We then noticed we had 10MB of free disk space on the mount point where the principal’s data files are stored.  I knew something went amiss as this system should have at least 150GB free on that mount point.  I immediately checked the main database’s data file and was shocked to see an autgrowth size of 65536%.  The data file autogrew right before mirroring went into the suspended state. 65536%! I didn’t have a lot of time to research if this autgrowth problem was a known SQL Server bug, so I deferred that research to today.  A quick Google search yielded no results but emphasis on “quick”.  I checked our performance system, which was recently restored with a copy of the affected production database, and found the autogrowth setting to be 512MB.  So this autogrowth bug was encountered sometime in the last two weeks.  On February 26th, we had attempted to install SQL 2005 SP4 on production, however it had failed (PSS case open with Microsoft).  I suspected that the SP4 failure was somehow related to this autgrowth bug although that turned out not to be the case. I then tweeted (@TaraKizer) about this problem to see if the SQL Server community (#sqlhelp) had any insights.  It seems several people have either heard of this bug or encountered it.  Aaron Bertrand (blog|twitter) referred me to this Connect item. Our affected database originated on SQL Server 2000 and was upgraded to SQL Server 2005 in 2007.  Back on SQL Server 2000, we were using the default file growth setting which was a percentage.  Sometime after the 2005 upgrade is when we changed it to 512MB.  Our situation seemed to fit the bug Aaron referred to me, so now the question was whether Microsoft had fixed it yet. I received a reply to my tweet from Amit Banerjee (twitter) that it had been fixed in SP3 CU1 (KB958004).  My affected system is SP3 CU8, so I was initially confused why we had encountered the bug.  Because I don’t read things fully, I had missed that there are additional steps you have to follow after applying the bug fix.  Amit set me straight.  Although you can read this information in the KB article, I will also copy it here in case you are as lazy as me and miss the most important section of it (although if you are as lazy as me, you won’t have read this far down my blog post): This hotfix will prevent only future occurrences of this problem. For example, if you restore a database from SQL Server 2000 to a SQL Server 2005 instance that contains this hotfix, this problem will not occur. However, if you already have a database that is affected by this problem, you must follow these steps to resolve this problem manually: Apply this hotfix. Set the file growth settings for the affected files to percentage settings, and then set the settings back to megabyte settings. Take the database offline, and then bring it back online. Verify that the values of the is_percent_growth column are correct in the sys.database_files system table and in the sys.master_files system table.

• Why Is Hibernation Still Used?

  - by Jason Fitzpatrick

  With the increased prevalence of fast solid-state hard drives, why do we still have system hibernation? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Moses wants to know why he should use hibernate on a desktop machine: I’ve never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I’ve never truly understood why it’s used. With today’s technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me [on desktop computers] when modern technology is considered, but perhaps there are applications that I’m not considering. What was the original purpose behind hibernation, and why do people still use it? Quite a few people use hibernate, so what is Moses missing in the big picture? The Answer SuperUser contributor Vignesh4304 writes: Normally hibernate mode saves your computer’s memory, this includes for example open documents and running applications, to your hard disk and shuts down the computer, it uses zero power. Once the computer is powered back on, it will resume everything where you left off. You can use this mode if you won’t be using the laptop/desktop for an extended period of time, and you don’t want to close your documents. Simple Usage And Purpose: Save electric power and resuming of documents. In simple terms this comment serves nice e.g (i.e. you will sleep but your memories are still present). Why it’s used: Let me describe one sample scenario. Imagine your battery is low on power in your laptop, and you are working on important projects on your machine. You can switch to hibernate mode – it will result your documents being saved, and when you power on, the actual state of application gets restored. Its main usage is like an emergency shutdown with an auto-resume of your documents. MagicAndre1981 highlights the reason we use hibernate everyday: Because it saves the status of all running programs. I leave all my programs open and can resume working the next day very easily. Doing a real boot would require to start all programs again, load all the same files into those programs, get to the same place that I was at before, and put all my windows in exactly the same place. Hibernating saves a lot of work pulling these things back up again. It’s not unusual to find computers around the office here that have been hibernated day in and day out for months without an actual full system shutdown and restart. It’s enormously convenient to freeze your work space at the exact moment you stopped working and to turn right around and resume there the next morning. Have something to add to the explanation? Sound off in the the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

• How to Draw Lines on the Screen

  - by Geertjan

  I've seen occasional questions on mailing lists about how to use the NetBeans Visual Library to draw lines, e.g., to make graphs or diagrams of various kinds by drawing on the screen. So, rather than drag/drop causing widgets to be added, you'd want widgets to be added on mouse clicks, and you'd want to be able to connect those widgets together somehow. Via the code below, you'll be able to click on the screen, which causes a dot to appear. When you have multiple dots, you can hold down the Ctrl key and connect them together. A guiding line appears to help you position the dots exactly in line with each other. When you go to File | Print, you'll be able to preview and print the diagram you've created. A picture that speaks 1000 words: Here's the code: public final class PlotterTopComponent extends TopComponent { private final Scene scene; private final LayerWidget baseLayer; private final LayerWidget connectionLayer; private final LayerWidget interactionLayer; public PlotterTopComponent() { initComponents(); setName(Bundle.CTL_PlotterTopComponent()); setToolTipText(Bundle.HINT_PlotterTopComponent()); setLayout(new BorderLayout()); this.scene = new Scene(); this.baseLayer = new LayerWidget(scene); this.interactionLayer = new LayerWidget(scene); this.connectionLayer = new LayerWidget(scene); scene.getActions().addAction(new SceneCreateAction()); scene.addChild(baseLayer); scene.addChild(interactionLayer); scene.addChild(connectionLayer); add(scene.createView(), BorderLayout.CENTER); putClientProperty("print.printable", true); } private class SceneCreateAction extends WidgetAction.Adapter { @Override public WidgetAction.State mousePressed(Widget widget, WidgetAction.WidgetMouseEvent event) { if (event.getClickCount() == 1) { if (event.getButton() == MouseEvent.BUTTON1 || event.getButton() == MouseEvent.BUTTON2) { baseLayer.addChild(new BlackDotWidget(scene, widget, event)); repaint(); return WidgetAction.State.CONSUMED; } } return WidgetAction.State.REJECTED; } } private class BlackDotWidget extends ImageWidget { public BlackDotWidget(Scene scene, Widget widget, WidgetAction.WidgetMouseEvent event) { super(scene); setImage(ImageUtilities.loadImage("org/netbeans/plotter/blackdot.gif")); setPreferredLocation(widget.convertLocalToScene(event.getPoint())); getActions().addAction( ActionFactory.createExtendedConnectAction( connectionLayer, new BlackDotConnectProvider())); getActions().addAction( ActionFactory.createAlignWithMoveAction( baseLayer, interactionLayer, ActionFactory.createDefaultAlignWithMoveDecorator())); } } private class BlackDotConnectProvider implements ConnectProvider { @Override public boolean isSourceWidget(Widget source) { return source instanceof BlackDotWidget && source != null ? true : false; } @Override public ConnectorState isTargetWidget(Widget src, Widget trg) { return src != trg && trg instanceof BlackDotWidget ? ConnectorState.ACCEPT : ConnectorState.REJECT; } @Override public boolean hasCustomTargetWidgetResolver(Scene arg0) { return false; } @Override public Widget resolveTargetWidget(Scene arg0, Point arg1) { return null; } @Override public void createConnection(Widget source, Widget target) { ConnectionWidget conn = new ConnectionWidget(scene); conn.setTargetAnchor(AnchorFactory.createCircularAnchor(target, 10)); conn.setSourceAnchor(AnchorFactory.createCircularAnchor(source, 10)); connectionLayer.addChild(conn); } } ... ... ... Note: The code above was written based on the Visual Library tutorials on the NetBeans Platform Learning Trail, in particular via the "ConnectScene" sample in the "test.connect" package, which is part of the very long list of Visual Library samples referred to in the Visual Library tutorials on the NetBeans Platform Learning Trail. The next steps are to add a reconnect action and an action to delete a dot by double-clicking on it. Would be interesting to change the connecting line so that the length of the line were to be shown, i.e., as you draw a line from one dot to another, you'd see a constantly changing number representing the current distance of the connecting line. Also, once lines are connected to form a rectangle, would be cool to be able to write something within that rectangle. Then one could really create diagrams, which would be pretty cool.

• A Reusable Builder Class for .NET testing

  - by Liam McLennan

  When writing tests, other than end-to-end integration tests, we often need to construct test data objects. Of course this can be done using the class’s constructor and manually configuring the object, but to get many objects into a valid state soon becomes a large percentage of the testing effort. After many years of painstakingly creating builders for each of my domain objects I have finally become lazy enough to bother to write a generic, reusable builder class for .NET. To use it you instantiate a instance of the builder and configuring it with a builder method for each class you wish it to be able to build. The builder method should require no parameters and should return a new instance of the type in a default, valid state. In other words the builder method should be a Func<TypeToBeBuilt>. The best way to make this clear is with an example. In my application I have the following domain classes that I want to be able to use in my tests: public class Person { public string Name { get; set; } public int Age { get; set; } public bool IsAndroid { get; set; } } public class Building { public string Street { get; set; } public Person Manager { get; set; } } The builder for this domain is created like so: build = new Builder(); build.Configure(new Dictionary<Type, Func<object>> { {typeof(Building), () => new Building {Street = "Queen St", Manager = build.A<Person>()}}, {typeof(Person), () => new Person {Name = "Eugene", Age = 21}} }); Note how Building depends on Person, even though the person builder method is not defined yet. Now in a test I can retrieve a valid object from the builder: var person = build.A<Person>(); If I need a class in a customised state I can supply an Action<TypeToBeBuilt> to mutate the object post construction: var person = build.A<Person>(p => p.Age = 99); The power and efficiency of this approach becomes apparent when your tests require larger and more complex objects than Person and Building. When I get some time I intend to implement the same functionality in Javascript and Ruby. Here is the full source of the Builder class: public class Builder { private Dictionary<Type, Func<object>> defaults; public void Configure(Dictionary<Type, Func<object>> defaults) { this.defaults = defaults; } public T A<T>() { if (!defaults.ContainsKey(typeof(T))) throw new ArgumentException("No object of type " + typeof(T).Name + " has been configured with the builder."); T o = (T)defaults[typeof(T)](); return o; } public T A<T>(Action<T> customisation) { T o = A<T>(); customisation(o); return o; } }

• Need help with chronic slow wifi connections

  - by mgeorge

  I have had chronic slow wifi connections on several networks for a while now, I think since my update to 12.04 when it came out. I have tried many of the tips and tricks already available out there in the forums with no luck (wicd, etc..). I want to see if any of you experts out there might be able to help me, and thanks in advance!!

• How can I have multiple layers in my map array?

  - by Manl400

  How do I load Levels in my game, as in Layer 1 would be Objects, Layer 2 would be Characters and so on. I only need 3 layers, and they will all be put on top of each other. i.e having a flower with a transparent background to be put on grass or dirt on the layer below.I would like to Read From the same file too. How would i go about doing this? Any help would be appreciated. I load the map from a level file which are just numbers corresponding to a tile in the tilesheet. Here is the level file [Layer1] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 [Layer2] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 [Layer3] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 And here is the code that interprets it void LoadMap(const char *filename, std::vector< std::vector <int> > &map) { std::ifstream openfile(filename); if(openfile.is_open()) { std::string line, value; int space; while(!openfile.eof()) { std::getline(openfile, line); if(line.find("[TileSet]") != std::string::npos) { state = TileSet; continue; } else if (line.find("[Layer1]") != std::string::npos) { state = Map; continue; } switch(state) { case TileSet: if(line.length() > 0) tileSet = al_load_bitmap(line.c_str()); break; case Map: std::stringstream str(line); std::vector<int> tempVector; while(!str.eof()) { std::getline(str, value, ' '); if(value.length() > 0) tempVector.push_back(atoi(value.c_str())); } map.push_back(tempVector); break; } } } else { } } and this is how it draws the map. Also the tile sheet is 1280 by 1280 and the tilesizeX and tilesizeY is 64 void DrawMap(std::vector <std::vector <int> > map) { int mapRowCount = map.size(); for(int i, j = 0; i < mapRowCount; i ++) { int mapColCount = map[i].size(); for (int j = 0; j < mapColCount; ++j) { int tilesetIndex = map[i][j]; int tilesetRow = floor(tilesetIndex / TILESET_COLCOUNT); int tilesetCol = tilesetIndex % TILESET_COLCOUNT; al_draw_bitmap_region(tileSet, tilesetCol * TileSizeX, tilesetRow * TileSizeY, TileSizeX, TileSizeY, j * TileSizeX, i * TileSizeX, NULL); } } } EDIT: http://i.imgur.com/Ygu0zRE.jpg

• “Apparently, you signed a software services agreement without fully understanding it.”

  - by Dave Ballantyne

  I am not a lawyer. Let me say that again, I am not a lawyer. Todays Dilbert has prompted me to post about my recent experience with SqlServer licensing. I'm in the technical realm and rarely have much to do with purchasing and licensing.  I say “I need” , budget realities will state weather I actually get.  However, I do keep my ear to the ground and due to my community involvement, I know, or at least have an understanding of, some licensing restrictions. Due to a misunderstanding, Microsoft Licensing stated that we needed licenses for our standby servers.  I knew that that was not the case,  and a quick tweet confirmed this. So after composing an email stating exactly what the machines in question were used for ie Log shipped to and used in a disaster recover scenario only,  and posting several Technet articles to back this up, we saved 2 enterprise edition licences, a not inconsiderable cost. However during this discussion, I was made aware of another ‘legalese’ document that could completely override the referenced articles, and anything I knew, or thought i knew, about SqlServer licensing. Personally, I had no knowledge of this.  The “Purchase Use Rights” agreement would appear to be the volume licensing equivalent of the “End User License Agreement” , click throughs we all know and ignore.  Here is a direct quote from Microsoft licensing, when asked for clarification. “Thanks for your email. Just to give some background on the Product Use Rights (PUR), licenses acquired through volume licensing are bound by the most recent PUR at the time of license acquisition. The link for the current PUR and PUR archive is http://www.microsoft.com/licensing/about-licensing/product-licensing.aspx. Further to this, products acquired through boxed product or pre-installed on hardware (OEM) are bound by the End User License Agreement (EULA). The PUR will explain limitations, license requirements and rulings on areas like multiplexing, virtualization, processor licensing, etc. When an article will appear on a Microsoft site or blog describing the licensing of a product, it will be using the PUR as a base. Due to the writing style or language used by the person writing areas of the website or technical blogs, the PUR is what you should use as a rule and not any of the other media. The PUR is updated quarterly and will reference every product available at that time working on the latest version unless otherwise stated. The crux of this is that the PUR is written after extensive discussions between the different branches of Microsoft (legal, technical, etc) and the wording is then approved. This is not always the case for some pages explaining licensing as they are merely intended to advise and not subject to the intense scrutiny as the PUR.” So, exactly what does that mean ? My take :  This is a living document, “updated quarterly” , though presumably this could be done on a whim and a fancy.  It could state , you are only licensed if ,that during install you stand in a corner juggling and that photographic evidence is required. A plainly ridiculous demand but,  what else could it override or new requirements could it state that change your existing understanding of the product or your legal usage of it. As i say, im not a lawyer, but are you checking the PURA prior to purchase ?

• Appropriate design / technologies to handle dynamic string formatting?

  - by Mark W

  recently I was tasked with implementing a way of adding support for versioning of hardware packet specifications to one of our libraries. First a bit of information about the project. We have a hardware library which has classes for each of the various commands we support sending to our hardware. These hardware modules are essentially just lights with a few buttons, and a 2 or 4 digit display. The packets typically follow the format {SOH}AADD{ETX}, where AA is our sentinel action code, and DD is the device ID. These packet specs are different from one command to the next obviously, and the different firmware versions we have support different specifications. For example, on version 1 an action code of 14 may have a spec of {SOH}AADDTEXT{ETX} which would be AA = 14 literal, DD = device ID, TEXT = literal text to display on the device. Then we come out with a revision with adds an extended byte(s) onto the end of the packet like this {SOH}AADDTEXTE{ETX}. Assume the TEXT field is fixed width for this example. We have now added a new field onto the end which could be used to say specify the color or flash rate of the text/buttons. Currently this java library only supports one version of the commands, the latest. In our hardware library we would have a class for this command, say a DisplayTextArgs.java. That class would have fields for the device ID, the text, and the extended byte. The command class would expose a method which generates the string ("{SOH}AADDTEXTE{ETX}") using the value from the class. In practice we would create the Args class as needed, populate the fields, call the method to get our packet string, then ship that down across the CAN. Some of our other commands specification can vary for the same command, on the same version, depending on some runtime state. For example, another command for version 1 may be {SOH}AA{ETX}, where this action code clears all of the modules behind a specific controller device of their text. We may overload this packet to have option fields with multiple meanings like {SOH}AAOC{ETX} where OC is literal text, which tells the controller to only clear text on a specific module type, and to leave the others alone, or the spec could also have an option format of {SOH}AADD{ETX} to clear the text off a a specific device. Currently, in the method which generates the packet string, we would evaluate fields on the args class to determine which spec we will be using when formatting the packet. For this example, it would be along the lines of: if m_DeviceID != null then use {SOH}AADD{ETX} else if m_ClearOCs == true then use {SOH}AAOC{EXT} else use {SOH}AA{ETX} I had considered using XML, or a database to store String.format format strings, which were linked to firmware version numbers in some table. We would load them up at startup, and pass in the version number of the hardwares firmware we are currently using (I can query the devices for their firmware version, but the version is not included in all packets as part of the spec). This breaks down pretty quickly because of the dynamic nature of how we select which version of the command to use. I then considered using a rule engine to possibly build out expressions which could be interpreted at runtume, to evaluate the args class's state, and from that select the appropriate format string to use, but my brief look at rule engines for java scared me away with its complexity. While it seems like it might be a viable solution, it seems overly complex. So this is why I am here. I wouldn't say design is my strongest skill, and im having trouble figuring out the best way to approach this problem. I probably wont be able to radically change the args classes, but if the trade off was good enough, I may be able to convince my boss that the change is appropriate. What I would like from the community is some feedback on some best practices / design methodologies / API or other resources which I could use to accomplish: Logic to determine which set of commands to use for a given firmware version Of those command, which version of each command to use (based on the args classes state) Keep the rules logic decoupled from the application so as to avoid needing releases for every firmware version Be simple enough so I don't need weeks of study and trial and error to implement effectively.

• I am not satisfied with my career and accomplished nothing in my life. what should I do now [on hold]

  - by user2906155

  After my complete my College education I got chance to work on software programming. I work on few software and now nothing make me feel good. I don't like web-programming. Can't have too much mind to play with other people in team a designer or a senior. it's totally time wasting for me. We do integration without any source code control. copy through pen drive. I write in too many language for web-programming but know nothing about any language specially. I don't like to have a BOSS. I would like to do something on my own. From last 3 year I thing I will got a better job but I am unable to get it. I am not good at Programming nor my English is native. I have a big list for pay then my salary. I have problem with nothing. my atmosphere is about illiterate people. they abuse 24 hours a day. this thing make me sick. people watch CRIME patrol my home (watching rape in TV because it's happen to someone). I do my work from home. I don't like to live in my state. All state is one of the biggest illiterate state of my country. Once I apply for a Job in China and it's look like I can get thing Job but I don't get it. My family doesn't want me to settle anywhere else. I told my family 4 time a day that I can't live in this worst situation. Everyone (including the person who I work for) tell me that you can do it only you have money. Now I really don't know how to make money. My job not allow me to work for anyone. My productivity going down since I don't learn anything new. I thing if this happen to me for next 2 year I don't have any knowledge more then a peon. I hate it. When I was in other city then I see that if I spent 7 days their all my 7 days going better. even I go for travelling in green places then I like it. but all I hate it where I work for. When I work on other city then I see my productivity are improved and I don't hate my work. I listen a song "If you don't your love what are you doing it for". I seriously don' t know what I still live here because this place gave me nothing but depression and trouble. for people I clear that I don't belong to RICH or middle class family. All I got is doing something on my own or help of someone. affording a rental place make my run on footpath. All I save in one month is just 10$ (approximately) (actually I afford some guys's education now). Can a programmer live worst life like this. I really not happy. Today is a festival in India and I don't celebrate it because I really hate myself. I want to do suicide. someone guide me how to start solving this headache

• Why won't xattr PECL extension build on 12.10?

  - by Dan Jones

  I was using the xattr pecl extension in 12.04 (in fact, I think since 10.04) without problem. Not surprisingly, I had to reinstall it after upgrading to 12.10 because of the new version of PHP. But now it fails to build, and I can't figure out why. Other PECL extensions have built fine. And I have libattr1 and libattr1-dev installed. Here's the output from the build: downloading xattr-1.1.0.tgz ...

• XNA Screen Manager problem with transitions

  - by NexAddo

  I'm having issues using the game statemanagement example in the game I am developing. I have no issues with my first three screens transitioning between one another. I have a main menu screen, a splash screen and a high score screen that cycle: mainMenuScreen->splashScreen->highScoreScreen->mainMenuScreen The screens change every 15 seconds. Transition times public MainMenuScreen() { TransitionOnTime = TimeSpan.FromSeconds(0.5); TransitionOffTime = TimeSpan.FromSeconds(0.0); currentCreditAmount = Global.CurrentCredits; } public SplashScreen() { TransitionOnTime = TimeSpan.FromSeconds(0.5); TransitionOffTime = TimeSpan.FromSeconds(0.5); } public HighScoreScreen() { TransitionOnTime = TimeSpan.FromSeconds(0.5); TransitionOffTime = TimeSpan.FromSeconds(0.5); } public GamePlayScreen() { TransitionOnTime = TimeSpan.FromSeconds(0.5); TransitionOffTime = TimeSpan.FromSeconds(0.5); } When a user inserts credits they can play the game after pressing start mainMenuScreen->splashScreen->highScoreScreen->(loops forever) || || || ===========Credits In============= || Start || \/ LoadingScreen || Start || \/ GamePlayScreen During each of these transitions, between screens, the same code is used, which exits(removes) all current active screens and respects transitions, then adds the new screen to the screen manager: foreach (GameScreen screen in ScreenManager.GetScreens()) screen.ExitScreen(); //AddScreen takes a new screen to manage and the controlling player ScreenManager.AddScreen(new NameOfScreenHere(), null); Each screen is removed from the ScreenManager with ExitScreen() and using this function, each screen transition is respected. The problem I am having is with my gamePlayScreen. When the current game is finished and the transition is complete for the gamePlayScreen, it should be removed and the next screens should be added to the ScreenManager. GamePlayScreen Code Snippet private void FinishCurrentGame() { AudioManager.StopSounds(); this.UnloadContent(); if (Global.SaveDevice.IsReady) Stats.Save(); if (HighScoreScreen.IsInHighscores(timeLimit)) { foreach (GameScreen screen in ScreenManager.GetScreens()) screen.ExitScreen(); Global.TimeRemaining = timeLimit; ScreenManager.AddScreen(new BackgroundScreen(), null); ScreenManager.AddScreen(new MessageBoxScreen("Enter your Initials", true), null); } else { foreach (GameScreen screen in ScreenManager.GetScreens()) screen.ExitScreen(); ScreenManager.AddScreen(new BackgroundScreen(), null); ScreenManager.AddScreen(new MainMenuScreen(), null); } } The problem is that when isExiting is set to true by screen.ExitScreen() for the gamePlayScreen, the transition never completes the transition and removes the screen from the ScreenManager. Every other screen that I use the same technique to add and remove each screen fully transitions On/Off and is removed at the appropriate time from the ScreenManager, but noy my GamePlayScreen. Has anyone that has used the GameStateManagement example experienced this issue or can someone see the mistake I am making? EDIT This is what I tracked down. When the game is done, I call foreach (GameScreen screen in ScreenManager.GetScreens()) screen.ExitScreen(); to start the transition off process for the gameplay screen. At this point there is only 1 screen on the ScreenManager stack. The gamePlay screen gets isExiting set to true and starts to transition off. Right after the above call to ExitScreen() I add a background screen and menu screen to the screenManager: ScreenManager.AddScreen(new background(), null); ScreenManager.AddScreen(new Menu(), null); The count of the ScreenManager is now 3. What I noticed while stepping through the updates for GameScreen and ScreenManager, the gameplay screen never gets to the point where the transistion process finishes so the ScreenManager can remove it from the stack. This anomaly does not happen to any of my other screens when I switch between them.

• apt-get fails to upgrade, install, remove etc

• What's up with OCFS2?

  - by wcoekaer

  On Linux there are many filesystem choices and even from Oracle we provide a number of filesystems, all with their own advantages and use cases. Customers often confuse ACFS with OCFS or OCFS2 which then causes assumptions to be made such as one replacing the other etc... I thought it would be good to write up a summary of how OCFS2 got to where it is, what we're up to still, how it is different from other options and how this really is a cool native Linux cluster filesystem that we worked on for many years and is still widely used. Work on a cluster filesystem at Oracle started many years ago, in the early 2000's when the Oracle Database Cluster development team wrote a cluster filesystem for Windows that was primarily focused on providing an alternative to raw disk devices and help customers with the deployment of Oracle Real Application Cluster (RAC). Oracle RAC is a cluster technology that lets us make a cluster of Oracle Database servers look like one big database. The RDBMS runs on many nodes and they all work on the same data. It's a Shared Disk database design. There are many advantages doing this but I will not go into detail as that is not the purpose of my write up. Suffice it to say that Oracle RAC expects all the database data to be visible in a consistent, coherent way, across all the nodes in the cluster. To do that, there were/are a few options : 1) use raw disk devices that are shared, through SCSI, FC, or iSCSI 2) use a network filesystem (NFS) 3) use a cluster filesystem(CFS) which basically gives you a filesystem that's coherent across all nodes using shared disks. It is sort of (but not quite) combining option 1 and 2 except that you don't do network access to the files, the files are effectively locally visible as if it was a local filesystem. So OCFS (Oracle Cluster FileSystem) on Windows was born. Since Linux was becoming a very important and popular platform, we decided that we would also make this available on Linux and thus the porting of OCFS/Windows started. The first version of OCFS was really primarily focused on replacing the use of Raw devices with a simple filesystem that lets you create files and provide direct IO to these files to get basically native raw disk performance. The filesystem was not designed to be fully POSIX compliant and it did not have any where near good/decent performance for regular file create/delete/access operations. Cache coherency was easy since it was basically always direct IO down to the disk device and this ensured that any time one issues a write() command it would go directly down to the disk, and not return until the write() was completed. Same for read() any sort of read from a datafile would be a read() operation that went all the way to disk and return. We did not cache any data when it came down to Oracle data files. So while OCFS worked well for that, since it did not have much of a normal filesystem feel, it was not something that could be submitted to the kernel mail list for inclusion into Linux as another native linux filesystem (setting aside the Windows porting code ...) it did its job well, it was very easy to configure, node membership was simple, locking was disk based (so very slow but it existed), you could create regular files and do regular filesystem operations to a certain extend but anything that was not database data file related was just not very useful in general. Logfiles ok, standard filesystem use, not so much. Up to this point, all the work was done, at Oracle, by Oracle developers. Once OCFS (1) was out for a while and there was a lot of use in the database RAC world, many customers wanted to do more and were asking for features that you'd expect in a normal native filesystem, a real "general purposes cluster filesystem". So the team sat down and basically started from scratch to implement what's now known as OCFS2 (Oracle Cluster FileSystem release 2). Some basic criteria were : Design it with a real Distributed Lock Manager and use the network for lock negotiation instead of the disk Make it a Linux native filesystem instead of a native shim layer and a portable core Support standard Posix compliancy and be fully cache coherent with all operations Support all the filesystem features Linux offers (ACL, extended Attributes, quotas, sparse files,...) Be modern, support large files, 32/64bit, journaling, data ordered journaling, endian neutral, we can mount on both endian /cross architecture,.. Needless to say, this was a huge development effort that took many years to complete. A few big milestones happened along the way... OCFS2 was development in the open, we did not have a private tree that we worked on without external code review from the Linux Filesystem maintainers, great folks like Christopher Hellwig reviewed the code regularly to make sure we were not doing anything out of line, we submitted the code for review on lkml a number of times to see if we were getting close for it to be included into the mainline kernel. Using this development model is standard practice for anyone that wants to write code that goes into the kernel and having any chance of doing so without a complete rewrite or.. shall I say flamefest when submitted. It saved us a tremendous amount of time by not having to re-fit code for it to be in a Linus acceptable state. Some other filesystems that were trying to get into the kernel that didn't follow an open development model had a lot harder time and a lot harsher criticism. March 2006, when Linus released 2.6.16, OCFS2 officially became part of the mainline kernel, it was accepted a little earlier in the release candidates but in 2.6.16. OCFS2 became officially part of the mainline Linux kernel tree as one of the many filesystems. It was the first cluster filesystem to make it into the kernel tree. Our hope was that it would then end up getting picked up by the distribution vendors to make it easy for everyone to have access to a CFS. Today the source code for OCFS2 is approximately 85000 lines of code. We made OCFS2 production with full support for customers that ran Oracle database on Linux, no extra or separate support contract needed. OCFS2 1.0.0 started being built for RHEL4 for x86, x86-64, ppc, s390x and ia64. For RHEL5 starting with OCFS2 1.2. SuSE was very interested in high availability and clustering and decided to build and include OCFS2 with SLES9 for their customers and was, next to Oracle, the main contributor to the filesystem for both new features and bug fixes. Source code was always available even prior to inclusion into mainline and as of 2.6.16, source code was just part of a Linux kernel download from kernel.org, which it still is, today. So the latest OCFS2 code is always the upstream mainline Linux kernel. OCFS2 is the cluster filesystem used in Oracle VM 2 and Oracle VM 3 as the virtual disk repository filesystem. Since the filesystem is in the Linux kernel it's released under the GPL v2 The release model has always been that new feature development happened in the mainline kernel and we then built consistent, well tested, snapshots that had versions, 1.2, 1.4, 1.6, 1.8. But these releases were effectively just snapshots in time that were tested for stability and release quality. OCFS2 is very easy to use, there's a simple text file that contains the node information (hostname, node number, cluster name) and a file that contains the cluster heartbeat timeouts. It is very small, and very efficient. As Sunil Mushran wrote in the manual : OCFS2 is an efficient, easily configured, quickly installed, fully integrated and compatible, feature-rich, architecture and endian neutral, cache coherent, ordered data journaling, POSIX-compliant, shared disk cluster file system. Here is a list of some of the important features that are included : Variable Block and Cluster sizes Supports block sizes ranging from 512 bytes to 4 KB and cluster sizes ranging from 4 KB to 1 MB (increments in power of 2). Extent-based Allocations Tracks the allocated space in ranges of clusters making it especially efficient for storing very large files. Optimized Allocations Supports sparse files, inline-data, unwritten extents, hole punching and allocation reservation for higher performance and efficient storage. File Cloning/snapshots REFLINK is a feature which introduces copy-on-write clones of files in a cluster coherent way. Indexed Directories Allows efficient access to millions of objects in a directory. Metadata Checksums Detects silent corruption in inodes and directories. Extended Attributes Supports attaching an unlimited number of name:value pairs to the file system objects like regular files, directories, symbolic links, etc. Advanced Security Supports POSIX ACLs and SELinux in addition to the traditional file access permission model. Quotas Supports user and group quotas. Journaling Supports both ordered and writeback data journaling modes to provide file system consistency in the event of power failure or system crash. Endian and Architecture neutral Supports a cluster of nodes with mixed architectures. Allows concurrent mounts on nodes running 32-bit and 64-bit, little-endian (x86, x86_64, ia64) and big-endian (ppc64) architectures. In-built Cluster-stack with DLM Includes an easy to configure, in-kernel cluster-stack with a distributed lock manager. Buffered, Direct, Asynchronous, Splice and Memory Mapped I/Os Supports all modes of I/Os for maximum flexibility and performance. Comprehensive Tools Support Provides a familiar EXT3-style tool-set that uses similar parameters for ease-of-use. The filesystem was distributed for Linux distributions in separate RPM form and this had to be built for every single kernel errata release or every updated kernel provided by the vendor. We provided builds from Oracle for Oracle Linux and all kernels released by Oracle and for Red Hat Enterprise Linux. SuSE provided the modules directly for every kernel they shipped. With the introduction of the Unbreakable Enterprise Kernel for Oracle Linux and our interest in reducing the overhead of building filesystem modules for every minor release, we decide to make OCFS2 available as part of UEK. There was no more need for separate kernel modules, everything was built-in and a kernel upgrade automatically updated the filesystem, as it should. UEK allowed us to not having to backport new upstream filesystem code into an older kernel version, backporting features into older versions introduces risk and requires extra testing because the code is basically partially rewritten. The UEK model works really well for continuing to provide OCFS2 without that extra overhead. Because the RHEL kernel did not contain OCFS2 as a kernel module (it is in the source tree but it is not built by the vendor in kernel module form) we stopped adding the extra packages to Oracle Linux and its RHEL compatible kernel and for RHEL. Oracle Linux customers/users obviously get OCFS2 included as part of the Unbreakable Enterprise Kernel, SuSE customers get it by SuSE distributed with SLES and Red Hat can decide to distribute OCFS2 to their customers if they chose to as it's just a matter of compiling the module and making it available. OCFS2 today, in the mainline kernel is pretty much feature complete in terms of integration with every filesystem feature Linux offers and it is still actively maintained with Joel Becker being the primary maintainer. Since we use OCFS2 as part of Oracle VM, we continue to look at interesting new functionality to add, REFLINK was a good example, and as such we continue to enhance the filesystem where it makes sense. Bugfixes and any sort of code that goes into the mainline Linux kernel that affects filesystems, automatically also modifies OCFS2 so it's in kernel, actively maintained but not a lot of new development happening at this time. We continue to fully support OCFS2 as part of Oracle Linux and the Unbreakable Enterprise Kernel and other vendors make their own decisions on support as it's really a Linux cluster filesystem now more than something that we provide to customers. It really just is part of Linux like EXT3 or BTRFS etc, the OS distribution vendors decide. Do not confuse OCFS2 with ACFS (ASM cluster Filesystem) also known as Oracle Cloud Filesystem. ACFS is a filesystem that's provided by Oracle on various OS platforms and really integrates into Oracle ASM (Automatic Storage Management). It's a very powerful Cluster Filesystem but it's not distributed as part of the Operating System, it's distributed with the Oracle Database product and installs with and lives inside Oracle ASM. ACFS obviously is fully supported on Linux (Oracle Linux, Red Hat Enterprise Linux) but OCFS2 independently as a native Linux filesystem is also, and continues to also be supported. ACFS is very much tied into the Oracle RDBMS, OCFS2 is just a standard native Linux filesystem with no ties into Oracle products. Customers running the Oracle database and ASM really should consider using ACFS as it also provides storage/clustered volume management. Customers wanting to use a simple, easy to use generic Linux cluster filesystem should consider using OCFS2. To learn more about OCFS2 in detail, you can find good documentation on http://oss.oracle.com/projects/ocfs2 in the Documentation area, or get the latest mainline kernel from http://kernel.org and read the source. One final, unrelated note - since I am not always able to publicly answer or respond to comments, I do not want to selectively publish comments from readers. Sometimes I forget to publish comments, sometime I publish them and sometimes I would publish them but if for some reason I cannot publicly comment on them, it becomes a very one-sided stream. So for now I am going to not publish comments from anyone, to be fair to all sides. You are always welcome to email me and I will do my best to respond to technical questions, questions about strategy or direction are sometimes not possible to answer for obvious reasons.

• AIX Checklist for stable obiee deployment

  - by user554629

  Common AIX configuration issues     ( last updated 27 Aug 2012 ) OBIEE is a complicated system with many moving parts and connection points.The purpose of this article is to provide a checklist to discuss OBIEE deployment with your systems administrators. The information in this article is time sensitive, and updated as I discover new  issues or details. What makes OBIEE different? When Tech Support suggests AIX component upgrades to a stable, locked-down production AIX environment, it is common to get "push back".  "Why is this necessary?  We aren't we seeing issues with other software?"It's a fair question that I have often struggled to answer; here are the talking points: OBIEE is memory intensive.  It is the entire purpose of the software to trade memory for repetitive, more expensive database requests across a network. OBIEE is implemented in C++ and is very dependent on the C++ runtime to behave correctly. OBIEE is aggressively thread efficient;  if atomic operations on a particular architecture do not work correctly, the software crashes. OBIEE dynamically loads third-party database client libraries directly into the nqsserver process.  If the library is not thread-safe, or corrupts process memory the OBIEE crash happens in an unrelated part of the code.  These are extremely difficult bugs to find. OBIEE software uses 99% common source across multiple platforms:  Windows, Linux, AIX, Solaris and HPUX.  If a crash happens on only one platform, we begin to suspect other factors.  load intensity, system differences, configuration choices, hardware failures.  It is rare to have a single product require so many diverse technical skills.   My role in support is to understand system configurations, performance issues, and crashes.   An analyst trained in Business Analytics can't be expected to know AIX internals in the depth required to make configuration choices.  Here are some guidelines. AIX C++ Runtime must be at  version 11.1.0.4$ lslpp -L | grep xlC.aixobiee software will crash if xlC.aix.rte is downlevel;  this is not a "try it" suggestion.Nov 2011 11.1.0.4 version  is appropriate for all AIX versions ( 5, 6, 7 )Download from here:https://www-304.ibm.com/support/docview.wss?uid=swg24031426 No reboot is necessary to install, it can even be installed while applications are using the current version.Restart the apps, and they will pick up the latest version. AIX 5.3 Technology Level 12 is required when running on Power5,6,7 processorsAIX 6.1 was introduced with the newer Power chips, and we have seen no issues with 6.1 or 7.1 versions.Customers with an unstable deployment, dozens of unexplained crashes, became stable after the upgrade.If your AIX system is 5.3, the minimum TL level should be at or higher than this:$ oslevel -s  5300-12-03-1107IBM typically supports only the two latest versions of AIX ( 6.1 and 7.1, for example).  AIX 5.3 is still supported and popular running in an LPAR. obiee userid limits$ ulimit -Ha  ( hard limits )$ ulimit -a   ( default limits )core file size (blocks)     unlimiteddata seg size (kbytes)      unlimitedfile size (blocks)          unlimitedmax memory size (kbytes)    unlimitedopen files                  10240 cpu time (seconds)          unlimitedvirtual memory (kbytes)     unlimitedIt is best to establish the values in /etc/security/limitsroot user is needed to observe and modify this file.If you modify a limit, you will need to relog in to change it again.  For example,$ ulimit -c 0$ ulimit -c 2097151cannot modify limit: Operation not permitted$ ulimit -c unlimited$ ulimit -c0There are only two meaningful values for ulimit -c ; zero or unlimited.Anything else is likely to produce a truncated core file that cannot be analyzed. Deploy 32-bit or 64-bit ?Early versions of OBIEE offered 32-bit or 64-bit choice to AIX customers.The 32-bit choice was needed if a database vendor did not supply a 64-bit client library.That's no longer an issue and beginning with OBIEE 11, 32-bit code is no longer shipped.A common error that leads to "out of memory" conditions to to accept the 32-bit memory configuration choices on 64-bit deployments.  The significant configuration choices are: Maximum process data (heap) size is in an AIX environment variableLDR_CNTRL=IGNOREUNLOAD@LOADPUBLIC@PREREAD_SHLIB@MAXDATA=0x... Two thread stack sizes are made in obiee NQSConfig.INI[ SERVER ]SERVER_THREAD_STACK_SIZE = 0;DB_GATEWAY_THREAD_STACK_SIZE = 0; Sort memory in NQSConfig.INI[ GENERAL ]SORT_MEMORY_SIZE = 4 MB ;SORT_BUFFER_INCREMENT_SIZE = 256 KB ; Choosing a value for MAXDATA:0x080000000  2GB Default maximum 32-bit heap size ( 8 with 7 zeros )0x100000000  4GB 64-bit breaking even with 32-bit ( 1 with 8 zeros )0x200000000  8GB 64-bit double 32-bit max0x400000000 16GB 64-bit safetyUsing 2GB heap size for a 64-bit process will almost certainly lead to an out-of-memory situation.Registers are twice as big ... consume twice as much memory in the heap.Upgrading to a 4GB heap for a 64-bit process is just "breaking even" with 32-bit.A 32-bit process is constrained by the 32-bit virtual addressing limits.  Heap memory is used for dynamic requirements of obiee software, thread stacks for each of the configured threads, and sometimes for shared libraries. 64-bit processes are not constrained in this way;  extra heap space can be configured for safety against a query that might create a sudden requirement for excessive storage.  If the storage is not available, this query might crash the whole server and disrupt existing users.There is no performance penalty on AIX for configuring more memory than required;  extra memory can be configured for safety.  If there are no other considerations, start with 8GB.Choosing a value for Thread Stack size:zero is the value documented to select an appropriate default for thread stack size.  My preference is to change this to an absolute value, even if you intend to use the documented default;  it provides better documentation and removes the "surprise" factor.There are two thread types that can be configured. GATEWAY is used by a thread pool to call a database client library to establish a DB connection.The default size is 256KB;  many customers raise this to 512KB ( no performance penalty for over-configuring ). This value must be set to 1 MB if Teradata connections are used. SERVER threads are used to run queries.  OBIEE uses recursive algorithms during the analysis of query structures which can consume significant thread stack storage.  It's difficult to provide guidance on a value that depends on data and complexity.  The general notion is to provide more space than you think you need,  "double down" and increase the value if you run out, otherwise inspect the query to understand why it is too complex for the thread stack.  There are protections built into the software to abort a single user query that is too complex, but the algorithms don't cover all situations.256 KB  The default 32-bit stack size.  Many customers increased this to 512KB on 32-bit.  A 64-bit server is very likely to crash with this value;  the stack contains mostly register values, which are twice as big.512 KB  The documented 64-bit default.  Some early releases of obiee didn't set this correctly, resulting in 256KB stacks.1 MB  The recommended 64-bit setting.  If your system only ever uses 512KB of stack space, there is no performance penalty for using 1MB stack size.2 MB  Many large customers use this value for safety.  No performance penalty.nqscheduler does not use the NQSConfig.INI file to set thread stack size.If this process crashes because the thread stack is too small, use this to set 2MB:export OBI_BACKGROUND_STACK_SIZE=2048 Shared libraries are not (shared) When application libraries are loaded at run-time, AIX makes a decision on whether to load the libraries in a "public" memory segment.  If the filesystem library permissions do not have the "Read-Other" permission bit, AIX loads the library into private process memory with two significant side-effects:* The libraries reduce the heap storage available.      Might be significant in 32-bit processes;  irrelevant in 64-bit processes.* Library code is loaded into multiple real pages for execution;  one copy for each process.Multiple execution images is a significant issue for both 32- and 64-bit processes.The "real memory pages" saved by using public memory segments is a minor concern.  Today's machines typically have plenty of real memory.The real problem with private copies of libraries is that they consume processor cache blocks, which are limited.   The same library instructions executing in different real pages will cause memory delays as the i-cache ( instruction cache 128KB blocks) are refreshed from real memory.   Performance loss because instructions are delayed is something that is difficult to measure without access to low-level cache fault data.   The machine just appears to be running slowly for no observable reason.This is an easy problem to detect, and an easy problem to correct.Detection:  "genld -l" AIX command produces a list of the libraries used by each process and the AIX memory address where they are loaded.32-bit public segment is 13 ( "dxxxxxxx" ).   private segments are 2-a.64-bit public segment is 9 ( "9xxxxxxxxxxxxxxx") ; private segment is 8.genld -l | grep -v ' d| 9' | sort +2provides a list of privately loaded libraries. Repair: chmod o+r <libname>AIX shared libraries will have a suffix of ".so" or ".a".Another technique is to change all libraries in a selected directory to repair those that might not be currently loaded.   The usual directories that need repair are obiee code, httpd code and plugins, database client libraries and java.chmod o+r /shr/dir/*.a /shr/dir/*.so Configure your system for diagnosticsProduction systems shouldn't crash, and yet bad things happen to good software.If obiee software crashes and produces a core, you should configure your system for reliable transfer of the failing conditions to Oracle Tech Support.  Here's what we need to be able to diagnose a core file from your system.* fullcore enabled. chdev -lsys0 -a fullcore=true* core naming enabled. chcore -n on -d* ulimit must not truncate core. see item 3.* pstack.sh is used to capture core documentation.* obidoc is used to capture current AIX configuration.* snapcore  AIX utility captures core and libraries. Use the proper syntax. $ snapcore -r corename executable-fullpath   /tmp/snapcore will contain the .pax.Z output file.  It is compressed.* If cores are directed to a common directory, ensure obiee userid can write to the directory.  ( chcore -p /cores -d ; chmod 777 /cores )The filesystem must have sufficient space to hold a crashing obiee application.Use:  df -k  Check the "Free" column ( not "% Used" )  8388608 is 8GB. Disable Oracle Client Library signal handlingThe Oracle DB Client Library is frequently distributed with the sqlplus development kit.By default, the library enables a signal handler, which will document a call stack if the application crashes.   The signal handler is not needed, and definitely disruptive to obiee diagnostics.   It needs to be disabled.   sqlnet.ora is typically located at:   $ORACLE_HOME/network/admin/sqlnet.oraAdd this line at the top of the file:   DIAG_SIGHANDLER_ENABLED=FALSE Disable async query in the RPD connection pool.This might be an obiee 10.1.3.4 issue only ( still checking  )."async query" must be disabled in the connection pools.It was designed to enable query cancellation to a database, and turned out to have too many edge conditions in normal communication that produced random corruption of data and crashes.  Please ensure it is turned off in the RPD. Check AIX error report (errpt).Errors external to obiee applications can trigger crashes.  $ /bin/errpt -aHardware errors ( firmware, adapters, disks ) should be reported to IBM support.All application core files are recorded by AIX;  the most recent ones are listed first.
