  - by Ayesha Ahmad

  i started working with ubuntu 11.10 last year. i upgraded to 12.04 a week back. since then i have had all sorts of problems with network connection. first had to install the new driver. the hardware switch somehow got disabled then the above problem arrived. even tho the options are all enabled, the OS is not able to detect scan available network connections. also i have to bring to notice that once in a while it does get connected, can not explain how it happens. I want to fix this problem once and for all. please help. ifconfig: eth0 Link encap:Ethernet HWaddr f0:4d:a2:51:b3:c8 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:44 eth1 Link encap:Ethernet HWaddr 1c:65:9d:67:d5:e1 inet6 addr: fe80::1e65:9dff:fe67:d5e1/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:170 TX packets:0 errors:27 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 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:16436 Metric:1 RX packets:344 errors:0 dropped:0 overruns:0 frame:0 TX packets:344 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:20336 (20.3 KB) TX bytes:20336 (20.3 KB) lshw -c network *-network description: Wireless interface product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: eth1 version: 01 serial: 1c:65:9d:67:d5:e1 width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=wl0 driverversion=5.100.82.38 latency=0 multicast=yes wireless=IEEE 802.11 resources: irq:17 memory:f0500000-f0503fff *-network description: Ethernet interface product: AR8152 v1.1 Fast Ethernet vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:04:00.0 logical name: eth0 version: c1 serial: f0:4d:a2:51:b3:c8 capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=atl1c driverversion=1.0.1.0-NAPI firmware=N/A latency=0 multicast=yes port=twisted pair resources: irq:44 memory:f0400000-f043ffff ioport:2000(size=128) iwconfig lo no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:0 Noise level:196 Rx invalid nwid:0 invalid crypt:0 invalid misc:0 eth0 no wireless extensions. lspci 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 18) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) 00:1a.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 (rev 06) 00:1c.1 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 2 (rev 06) 00:1c.5 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 6 (rev 06) 00:1d.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev a6) 00:1f.0 ISA bridge: Intel Corporation Mobile 5 Series Chipset LPC Interface Controller (rev 06) 00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 6 port SATA AHCI Controller (rev 06) 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller (rev 06) 00:1f.6 Signal processing controller: Intel Corporation 5 Series/3400 Series Chipset Thermal Subsystem (rev 06) 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 04:00.0 Ethernet controller: Atheros Communications Inc.

• Running evrouter at boot with init.d, or after xserver starts

  - by J V

  I'm using evrouter to set up mouse button binds, and init.d to start it. My init.d file: #!/bin/bash #Simple init.d script to run evrouter ### BEGIN INIT INFO # Provides: evrouter # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Set evrouter bindings # Description: Set evrouter bindings at boot time. ### END INIT INFO config="/opt/hacks/evrouterrc" case "$1" in start|restart|reload|force-reload) evrouter -c "$config" /dev/input/event* ;; stop) echo "Evrouter is not a daemon, change settings file at '$config' and restart" ;; *) echo "Usage: $0 start" >&2 exit 3 ;; esac evrouter however complains that: evrouter: could not open display "". If evrouter requires xserver to be up, how do I get init to wait until after xserver starts to run this script? If xserver restarts will this script run automatically? Running this with sudo services evrouter start still results in this error, can init.d scripts not tell where my display is? (Not exactly familiar with init, runlevels, etc)

• How can I determine which named property (or properties) are filling my exchange 2007 information st

  - by Mikey B

  Hi Guys, I'm experiencing the following error on an Exchange 2007 server: Event ID: 9667 Type: Error Category: General Source: msgidNamedPropsQuotaError Description: Failed to create a new named property for database "" because the number of named properties reached the quota limit (). User attempting to create the named property: . Named property GUID: . Named property name/id: . I understand that this can occur if the exchange information store is filling up with named properties... but I don't know how to determine which specific named property is at fault here. Is there a way to examine the DB for this type of info to see if there's a specific recurring named property that is consuming resources? -M

• HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL

  - by Bertrand Matthelié

  Oracle MySQL Engineer Ulf Wendel delivered yesterday a talk about his Proof of Concept at the International PHP Conference in Berlin entitled: “HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL - make it happen, today.” The presentation has been featured today on the home page of SlideShare, both into the “Hot on Facebook” and “Hot on Twitter” sections. Well done, Ulf! Especially just before the wedding…:) Presentation abstract: See how a MySQL Server plugin can be developed to build all this into MySQL. A new direct wire between MySQL and client-side JavaScript is created. MySQL speaks HTTP, replies JSON and offers server-side JavaScript. Server-side JavaScript gets access to MySQL data and does Map&Reduce of JSON documents stored in MySQL. Fast? 2-4x faster than proxing client-side JavaScript request through PHP/Apache. Reasonable results... Slides available here. And, talking about innovation… today is Oracle’s MySQL Innovation Day, you can still attend the event online. Register Now, it starts at 9.00 am PT.

• How to create managed properties at site collection level in SharePoint2013

  - by ybbest

  In SharePoint2013, you can create managed properties at site collection. Today, I’d like to show you how to do so through PowerShell. 1. Define your managed properties and crawled properties and managed property Type in an external csv file. PowerShell script will read this file and create the managed and the mapping. 2. As you can see I also defined variant Type, this is because you need the variant type to create the crawled property. In order to have the crawled properties, you need to do a full crawl and also make sure you have data populated for your custom column. However, if you do not want to a full crawl to create those crawled properties, you can create them yourself by using the PowerShell; however you need to make sure the crawled properties you created have the same name if created by a full crawl. Managed properties type: Text = 1 Integer = 2 Decimal = 3 DateTime = 4 YesNo = 5 Binary = 6 Variant Type: Text = 31 Integer = 20 Decimal = 5 DateTime = 64 YesNo = 11 3. You can use the following script to create your managed properties at site collection level, the differences for creating managed property at site collection level is to pass in the site collection id. param( [string] $siteUrl="http://SP2013/", [string] $searchAppName = "Search Service Application", $ManagedPropertiesList=(IMPORT-CSV ".\ManagedProperties.csv") ) Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue $searchapp = $null function AppendLog { param ([string] $msg, [string] $msgColor) $currentDateTime = Get-Date $msg = $msg + " --- " + $currentDateTime if (!($logOnly -eq $True)) { # write to console Write-Host -f $msgColor $msg } # write to log file Add-Content $logFilePath $msg } $scriptPath = Split-Path $myInvocation.MyCommand.Path $logFilePath = $scriptPath + "\CreateManagedProperties_Log.txt" function CreateRefiner {param ([string] $crawledName, [string] $managedPropertyName, [Int32] $variantType, [Int32] $managedPropertyType,[System.GUID] $siteID) $cat = Get-SPEnterpriseSearchMetadataCategory –Identity SharePoint -SearchApplication $searchapp $crawledproperty = Get-SPEnterpriseSearchMetadataCrawledProperty -Name $crawledName -SearchApplication $searchapp -SiteCollection $siteID if($crawledproperty -eq $null) { Write-Host AppendLog "Creating Crawled Property for $managedPropertyName" Yellow $crawledproperty = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -VariantType $variantType -SiteCollection $siteID -Category $cat -PropSet "00130329-0000-0130-c000-000000131346" -Name $crawledName -IsNameEnum $false } $managedproperty = Get-SPEnterpriseSearchMetadataManagedProperty -Identity $managedPropertyName -SearchApplication $searchapp -SiteCollection $siteID -ErrorAction SilentlyContinue if($managedproperty -eq $null) { Write-Host AppendLog "Creating Managed Property for $managedPropertyName" Yellow $managedproperty = New-SPEnterpriseSearchMetadataManagedProperty -Name $managedPropertyName -Type $managedPropertyType -SiteCollection $siteID -SearchApplication $searchapp -Queryable:$true -Retrievable:$true -FullTextQueriable:$true -RemoveDuplicates:$false -RespectPriority:$true -IncludeInMd5:$true } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } if($mappedProperty -eq $null) { Write-Host AppendLog "Creating Crawled -> Managed Property mapping for $managedPropertyName" Yellow New-SPEnterpriseSearchMetadataMapping -CrawledProperty $crawledproperty -ManagedProperty $managedproperty -SearchApplication $searchapp -SiteCollection $siteID } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } #Get-FASTSearchMetadataCrawledPropertyMapping -ManagedProperty $managedproperty } $searchapp = Get-SPEnterpriseSearchServiceApplication $searchAppName $site= Get-SPSite $siteUrl $siteId=$site.id Write-Host "Start creating Managed properties" $i = 1 FOREACH ($property in $ManagedPropertiesList) { $propertyName=$property.managedPropertyName $crawledName=$property.crawledName $managedPropertyType=$property.managedPropertyType $variantType=$property.variantType Write-Host $managedPropertyType Write-Host "Processing managed property $propertyName $($i)..." $i++ CreateRefiner $crawledName $propertyName $variantType $managedPropertyType $siteId Write-Host "Managed property created " $propertyName } Key Concepts Crawled Properties: Crawled properties are discovered by the search index service component when crawling content. Managed Properties: Properties that are part of the Search user experience, which means they are available for search results, advanced search, and so on, are managed properties. Mapping Crawled Properties to Managed Properties: To make a crawled property available for the Search experience—to make it available for Search queries and display it in Advanced Search and search results—you must map it to a managed property.

• SQL SERVER – Learn SQL Server 2014 Online in a Day – My Latest Pluralsight Course

  - by Pinal Dave

  Click here watch SQL Server 2014 Administration New Features.  SQL Server 2014 was released earlier this year and it has been extremely popular in Microsoft world. Here is the announcement for everyone, who have been asking me to build a tutorial around SQL Server 2014. I have authored latest Pluralsight courses on the subject of SQL Server 2014. This course is 4 hours and 17 minutes long, but the best part is that this course contains all the latest features of SQL Server 2014. I have build this course with the assumption that DBA is familiar with earlier versions of SQL Server and wants to explore and learn new features of SQL Server 2014. The Challenge I Faced The biggest challenge I faced was how to come up with the outline for the course. The reason is that there are so many different features introduced in SQL Server 2014 that is will be difficult to cover each of the features in a single course. I wanted to cover the topics which are the most relevant and useful to developers, but in addition I also wanted to cover the topics which may be useful to develop if they know that they exists in the product. I finally decided to depend on blog readers and few of the SQL Experts. I reached out to selected 20 people via email and gave them a list of the topics which I should be covering in this course. They all work in different organizations and have a good understanding about the need of the DBA and Developers. Based on their feedback, I was able to come up with a very good outline which is currently very popular with Pluralsight library. Lots of people have asked me how was I able to come up with a course content outline so accurately. The credit for the same goes to the developers and DBA, who have voted in the topics and have helped me to build a very solid outline for the course. Outline of the Course Here is a quick outline for the course: Introduction Backup Enhancements Security Enhancements Columnstore Enhancements Online Data Operations Enhancements Enhancements with Microsoft Azure SSD Buffer Pool Extensions Resource Governor IO Miscellaneous Features Online Index Rebuilding Live Plans for Long Running Queries Transaction Durability Cardinality Estimation In Memory OLTP Optimization Well, I had a great fun working on the topics which I have mentioned in the outline. I am very confident that once you start with the course, you will indeed understand how each of the topics builds and presented. I have made sure that each of the topic has a vivid and clear story to begin with. I first explain the story and right after that I explain the concept. Who Should Attend This Course Everyone who has basic knowledge of SQL Server and wants to update themselves with SQL Server 2014. They should attend this course. One thing I have made sure that this course is easy to understand and I have decided complex subject into multiple parts. This way the learning is progressive and anyone with a poor knowledge of the subject can have enough time to understand the presented concept. Screenshot of the Course Here are few of the screenshot of the courses. How to Watch Video Course This course is available at Pluralsight, and you will need a valid login to Pluralsight. If you do not have Pluralsight login, you can quickly sign up for the FREE Trial.

• windows 7 crash during hibernation

  - by Andrew Fforts

  At times, when I hibernate my Dell Latitude e6400 with Windows 7 (64 bit), the laptop screen goes black as it should, but then it takes several minutes before it powers down. Then, when I attempt to "resume," Windows boots up from a fresh startup, with all my work lost, and tells me that it's recovered from a serious error. What can I do to resolve this problem? Other background info: -I got a new hard drive with plenty of space about a year ago; I only use a small fraction of that space. This sometimes happens when I don't have any programs running at all. If it's relevant, I do have Dropbox and OneDrive running in the background, though. -The problem usually occurs when I hibernate just after I unplug from an external monitor to bring my laptop home, but I believe it happens at other times, too. Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.4 Locale ID: 1033 Additional information about the problem: BCCode: 1000009f BCP1: 0000000000000004 BCP2: 0000000000000258 BCP3: FFFFFA80036DEB50 BCP4: FFFFF80000B9C510 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1

• Measuring ASP.NET and SharePoint output cache

  - by DigiMortal

  During ASP.NET output caching week in my local blog I wrote about how to measure ASP.NET output cache. As my posting was based on real work and real-life results then I thought that this posting is maybe interesting to you too. So here you can read what I did, how I did and what was the result. Introduction Caching is not effective without measuring it. As MVP Henn Sarv said in one of his sessions then you will get what you measure. And right he is. Lately I measured caching on local Microsoft community portal to make sure that our caching strategy is good enough in environment where this system lives. In this posting I will show you how to start measuring the cache of your web applications. Although the application measured is built on SharePoint Server publishing infrastructure, all those counters have same meaning as similar counters under pure ASP.NET applications. Measured counters I used Performance Monitor and the following performance counters (their names are similar on ASP.NET and SharePoint WCMS): Total number of objects added – how much objects were added to output cache. Total object discards – how much objects were deleted from output cache. Cache hit count – how many times requests were served by cache. Cache hit ratio – percent of requests served from cache. The first three counters are cumulative while last one is coefficient. You can use also other counters to measure the full effect of caching (memory, processor, disk I/O, network load etc before and after caching). Measuring process The measuring I describe here started from freshly restarted web server. I measured application during 12 hours that covered also time ranges when users are most active. The time range does not include late evening hours and night because there is nothing to measure during these hours. During measuring we performed no maintenance or administrative tasks on server. All tasks performed were related to usual daily content management and content monitoring. Also we had no advertisement campaigns or other promotions running at same time. The results You can see the results on following graphic.   Total number of objects added   Total object discards   Cache hit count   Cache hit ratio You can see that adds and discards are growing in same tempo. It is good because cache expires and not so popular items are not kept in memory. If there are more popular content then the these lines may have bigger distance between them. Cache hit count grows faster and this shows that more and more content is served from cache. In current case it shows that cache is filled optimally and we can do even better if we tune caches more. The site contains also pages that are discarded when some subsite changes (page was added/modified/deleted) and one modification may affect about four or five pages. This may also decrease cache hit count because during day the site gets about 5-10 new pages. Cache hit ratio is currently extremely good. The suggested minimum is about 85% but after some tuning and measuring I achieved 98.7% as a result. This is due to the fact that new pages are most often requested and after new pages are added the older ones are requested only sometimes. So they get discarded from cache and only some of these will return sometimes back to cache. Although this may also indicate the need for additional SEO work the result is very well in technical means. Conclusion Measuring ASP.NET output cache is not complex thing to do and you can start by measuring performance of cache as a start. Later you can move on and measure caching effect to other counters such as disk I/O, network, processors etc. What you have to achieve is optimal cache that is not full of items asked only couple of times per day (you can avoid this by not using too long cache durations). After some tuning you should be able to boost cache hit ratio up to at least 85%.

• JavaServer Faces 2.0 for the Cloud

  - by Janice J. Heiss

  A new article now up on otn/java by Deepak Vohra titled “JSF 2.0 for the Cloud, Part One,” shows how JavaServer Faces 2.0 provides features ideally suited for the virtualized computing resources of the cloud. The article focuses on @ManagedBean annotation, implicit navigation, and resource handling. Vohra illustrates how the container-based model found in Java EE 7, which allows portable applications to target single machines as well as large clusters, is well suited to the cloud architecture. From the article-- “Cloud services might not have been a factor when JavaServer Faces 2.0 (JSF 2.0) was developed, but JSF 2.0 provides features ideally suited for the cloud, for example:•    The path-based resource handling in JSF 2.0 makes handling virtualized resources much easier and provides scalability with composite components.•    REST-style GET requests and bookmarkable URLs in JSF 2.0 support the cloud architecture. Representational State Transfer (REST) software architecture is based on transferring the representation of resources identified by URIs. A RESTful resource or service is made available as a URI path. Resources can be accessed in various formats, such as XML, HTML, plain text, PDF, JPEG, and JSON, among others. REST offers the advantages of being simple, lightweight, and fast.•    Ajax support in JSF 2.0 is integrable with Software as a Service (SaaS) by providing interactive browser-based Web applications.” In Part Two of the series, Vohra will examine features such as Ajax support, view parameters, preemptive navigation, event handling, and bookmarkable URLs.Have a look at the article here.

• SQL Server Snapshot Replication Subscriber (Editable or Read-Only)

  - by NateReid

  I need to create a copy of my SQL 2008 R2 Enterprise database and have it located on the same server as the original. I will be using this second copy of the database as the target of a mostly read-only website. I understand that if I create this copy of the database using snapshot replication that all data changes in the subscriber database will be overwriten in the event of the next replication. The web application will try to write to this database to record login attempts, etc and will fail if its source database is read-only. In my case I do not need to keep these auditing records and they can therefore be overwriten each time a new snapshot is applied. My question is whether SQL Server forces the subcriber database to be read-only and is there any way around this? Thank you, Nate

• SQL SERVER – UNION ALL and ORDER BY – How to Order Table Separately While Using UNION ALL

  - by pinaldave

  I often see developers trying following syntax while using ORDER BY. SELECT Columns FROM TABLE1 ORDER BY Columns UNION ALL SELECT Columns FROM TABLE2 ORDER BY Columns However the above query will return following error. Msg 156, Level 15, State 1, Line 5 Incorrect syntax near the keyword ‘ORDER’. It is not possible to use two different ORDER BY in the UNION statement. UNION returns single resultsetand as per the Logical Query Processing Phases. However, if your requirement is such that you want your top and bottom query of the UNION resultset independently sorted but in the same resultset you can add an additional static column and order by that column. Let us re-create the same scenario. First create two tables and populated with sample data. USE tempdb GO -- Create table CREATE TABLE t1 (ID INT, Col1 VARCHAR(100)); CREATE TABLE t2 (ID INT, Col1 VARCHAR(100)); GO -- Sample Data Build INSERT INTO t1 (ID, Col1) SELECT 1, 'Col1-t1' UNION ALL SELECT 2, 'Col2-t1' UNION ALL SELECT 3, 'Col3-t1'; INSERT INTO t2 (ID, Col1) SELECT 3, 'Col1-t2' UNION ALL SELECT 2, 'Col2-t2' UNION ALL SELECT 1, 'Col3-t2'; GO If we SELECT the data from both the table using UNION ALL . -- SELECT without ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 GO We will get the data in following order. However, our requirement is to get data in following order. If we need data ordered by Column1 we can ORDER the resultset ordered by Column1. -- SELECT with ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 ORDER BY ID GO Now to get the data in independently sorted in UNION ALL let us add additional column OrderKey and use ORDER BY  on that column. I think the description does not do proper justice let us see the example here. -- SELECT with ORDER BY - with ORDER KEY SELECT ID, Col1, 'id1' OrderKey FROM t1 UNION ALL SELECT ID, Col1, 'id2' OrderKey FROM t2 ORDER BY OrderKey, ID GO The above query will give the desired result. Now do not forget to clean up the database by running the following script. -- Clean up DROP TABLE t1; DROP TABLE t2; GO Here is the complete script used in this example. USE tempdb GO -- Create table CREATE TABLE t1 (ID INT, Col1 VARCHAR(100)); CREATE TABLE t2 (ID INT, Col1 VARCHAR(100)); GO -- Sample Data Build INSERT INTO t1 (ID, Col1) SELECT 1, 'Col1-t1' UNION ALL SELECT 2, 'Col2-t1' UNION ALL SELECT 3, 'Col3-t1'; INSERT INTO t2 (ID, Col1) SELECT 3, 'Col1-t2' UNION ALL SELECT 2, 'Col2-t2' UNION ALL SELECT 1, 'Col3-t2'; GO -- SELECT without ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 GO -- SELECT with ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 ORDER BY ID GO -- SELECT with ORDER BY - with ORDER KEY SELECT ID, Col1, 'id1' OrderKey FROM t1 UNION ALL SELECT ID, Col1, 'id2' OrderKey FROM t2 ORDER BY OrderKey, ID GO -- Clean up DROP TABLE t1; DROP TABLE t2; GO I am sure there are many more ways to achieve this, what method would you use if you have to face the similar situation?

• How to ...set up new Java environment - largely interfaces...

  - by Chris Kimpton

  Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

• How can I recover Google Chrome extensions, settings after a Linux crash?

  - by Norman Ramsey

  I'm running Google Chrome 5.0.307.11 (Official Build 39572) beta on Debian Linux (lenny) kernel version 2.6.26-2-686. The machine is a laptop (Lenovo Thinkpad X300) and sometimes it freezes, usually shortly after wakeup from sleep. The only cure is the power button, but when I restart my Google Chrome web browser after such an event, Settings on the Options menu revert to defaults. Chrome removes all the extensions from ~/.config/google-chrome/Default/Extensions, leaving me with no extensions. The set of "pages last open" is lost. I'd love to know how to poke at the file system in order to recover any or all of this information, especially my extensions. It is a pain to re-do everything by hand each time. How can I recover Google Chrome's extensions and settings after a Linux crash?

• Whether to use UNION or OR in SQL Server Queries

  - by Dinesh Asanka

  Recently I came across with an article on DB2 about using Union instead of OR. So I thought of carrying out a research on SQL Server on what scenarios UNION is optimal in and which scenarios OR would be best. I will analyze this with a few scenarios using samples taken  from the AdventureWorks database Sales.SalesOrderDetail table. Scenario 1: Selecting all columns So we are going to select all columns and you have a non-clustered index on the ProductID column. --Query 1 : OR SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR ProductID =709 OR ProductID =998 OR ProductID =875 OR ProductID =976 OR ProductID =874 --Query 2 : UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 709 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 998 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 875 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 976 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 874 So query 1 is using OR and the later is using UNION. Let us analyze the execution plans for these queries. Query 1 Query 2 As expected Query 1 will use Clustered Index Scan but Query 2, uses all sorts of things. In this case, since it is using multiple CPUs you might have CX_PACKET waits as well. Let’s look at the profiler results for these two queries: CPU Reads Duration Row Counts OR 78 1252 389 3854 UNION 250 7495 660 3854 You can see from the above table the UNION query is not performing well as the  OR query though both are retuning same no of rows (3854).These results indicate that, for the above scenario UNION should be used. Scenario 2: Non-Clustered and Clustered Index Columns only --Query 1 : OR SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR ProductID =709 OR ProductID =998 OR ProductID =875 OR ProductID =976 OR ProductID =874 GO --Query 2 : UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 709 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 998 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 875 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 976 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 874 GO So this time, we will be selecting only index columns, which means these queries will avoid a data page lookup. As in the previous case we will analyze the execution plans: Query 1 Query 2 Again, Query 2 is more complex than Query 1. Let us look at the profile analysis: CPU Reads Duration Row Counts OR 0 24 208 3854 UNION 0 38 193 3854 In this analyzis, there is only slight difference between OR and UNION. Scenario 3: Selecting all columns for different fields Up to now, we were using only one column (ProductID) in the where clause.  What if we have two columns for where clauses and let us assume both are covered by non-clustered indexes? --Query 1 : OR SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR CarrierTrackingNumber LIKE 'D0B8%' --Query 2 : UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT * FROM Sales.SalesOrderDetail WHERE CarrierTrackingNumber  LIKE 'D0B8%' Query 1 Query 2: As we can see, the query plan for the second query has improved. Let us see the profiler results. CPU Reads Duration Row Counts OR 47 1278 443 1228 UNION 31 1334 400 1228 So in this case too, there is little difference between OR and UNION. Scenario 4: Selecting Clustered index columns for different fields Now let us go only with clustered indexes: --Query 1 : OR SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR CarrierTrackingNumber LIKE 'D0B8%' --Query 2 : UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT * FROM Sales.SalesOrderDetail WHERE CarrierTrackingNumber  LIKE 'D0B8%' Query 1 Query 2 Now both execution plans are almost identical except is an additional Stream Aggregate is used in the first query. This means UNION has advantage over OR in this scenario. Let us see profiler results for these queries again. CPU Reads Duration Row Counts OR 0 319 366 1228 UNION 0 50 193 1228 Now see the differences, in this scenario UNION has somewhat of an advantage over OR. Conclusion Using UNION or OR depends on the scenario you are faced with. So you need to do your analyzing before selecting the appropriate method. Also, above the four scenarios are not all an exhaustive list of scenarios, I selected those for the broad description purposes only.

• IIS 8 Random 503 service unavailable

  - by Ivo

  We migrated a busy website to Windows Server 2012 with IIS 8. The website randomly gives the error "503 service unavailable" after an user presses F5 the error is gone again. The website is build in ASP.NET MVC 3. The website runs on one application pool, with default settings There are around 500 to 900 concurrent users on the website during the day, and the error happens more often when there are more 650 users. The CPU and the memory use on the server is stable. There is nothing about the 503 errors in the application log, the IIS log and the event log. Does anyone has any clue what the problem can be or how we can trace the the problem?

• Asp.net Session State Revisited

  - by karan@dotnet

  Every now and then I see doubts and queries which I believe is the most discussed topic in the .net environment - Asp.net Sessions. So what really are they, why are they needed and what does browser and .net do with it. These and some of the other questions I hope to answer with this post. Because of the stateless nature of the HTTP protocol there is always a need of state management in a web application. There are many other ways to store data but I feel Session state is amongst the most powerful one. The ASP.NET session state is a technology that lets you store server-side, user-specific data. Our web applications can then use data to process request from the user for which the session state was instantiated. So when does a session is first created? When we start a asp.net application a non-expiring cookie is created and its called as ASP.NET_SessionId. Basically there are two methods for this depending upon how you configure this setting in your config file. The session ID can be a part of cookie as discussed above(called as ASP.NET_SessionId) or it is embedded in the browser’s URL. For the latter part we have to set cookie-less session in our web.config file. These Session ID’s are 120-bit random number that is represented by 20-character string. The cookie will be alive until you close your browser. If you browse from one app to another within the same domain, then both the apps will use the same session ID to track the session state. Why reuse? so that you don’t have to create a new session ID for each request. One can abandon one particular Session by calling Session.Abandon() which will stop the page processing and clear out the session data. A subsequent page request causes a brand new session object to be instantiated. So what happened to my cookie? Well the session cookie is still there even when one Session.Abandon() is called and another session object is created. The Session.Abandon() lets you clear out your session state without waiting for session timeout. By default, this time-out is a 20-minute sliding expiration. This expiration is refreshed every time that the user makes a request to the Web site and presents the session ID cookie. The Abandon method sets a flag in the session state object that indicates that the session state should be abandoned. If your app does not have global.asax then your session cookie will be killed at the end of each page request. So you need to have a global.asax file and Session_Start() handler to make sure that the session cookie will remain intact once its issued after the first page hit. The runtime invokes global.asax’s Session_OnEnd() when you call Session.Abandon() or the session times out. The session manager stores session data in HttpCache with sliding expiration where this timeout can be configured in the <sessionState> of web.config file. When the timeout is up the HttpCache will remove the session state object. Sometimes we want particular pages not to time out as compared to other pages in our applications. We can handle this in two ways. First, we can set a timer or may be a JavaScript function that refreshes the page after fixed intervals of time. The only thing being the page being cached locally and then the request is not made to the server so to prevent that you can add this to your page: <%@ OutputCache Location="None" VaryByParam="None" %> Second approach is to move your page into its own folder and then add a web.config to that folder to control the timeout. Also not all pages in your application will need access to session state. For those pages that do not, you can indicate that session state is not needed and prevent session data from being fetched from the store in requests to these pages. You can disable the session state at page level like this:<%@ Page EnableSessionState="False" %>tbc…

• Having fun with Reflection

  - by Nick Harrison

  I was once asked in a technical interview what I could tell them about Reflection.   My response, while a little tongue in cheek was that "I can tell you it is one of my favorite topics to talk about" I did get a laugh out of that and it was a great ice breaker.    Reflection may not be the answer for everything, but it often can be, or maybe even should be.     I have posted in the past about my favorite CopyTo method.   It can come in several forms and is often very useful.   I explain it further and expand on the basic idea here  The basic idea is to allow reflection to loop through the properties of two objects and synchronize the ones that are in common.   I love this approach for data binding and passing data across the layers in an application. Recently I have been working on a project leveraging Data Transfer Objects to pass data through WCF calls.   We won't go into how the architecture got this way, but in essence there is a partial duplicate inheritance hierarchy where there is a related Domain Object for each Data Transfer Object.     The matching objects do not share a common ancestor or common interface but they will have the same properties in common.    By passing the problems with this approach, let's talk about how Reflection and our friendly CopyTo could make the most of this bad situation without having to change too much. One of the problems is keeping the two sets of objects in synch.   For this particular project, the DO has all of the functionality and the DTO is used to simply transfer data back and forth.    Both sets of object have parallel hierarchies with the same properties being defined at the corresponding levels.   So we end with BaseDO,  BaseDTO, GenericDO, GenericDTO, ProcessAreaDO,  ProcessAreaDTO, SpecializedProcessAreaDO, SpecializedProcessAreaDTO, TableDo, TableDto. and so on. Without using Reflection and a CopyTo function, tremendous care and effort must be made to keep the corresponding objects in synch.    New properties can be added at any level in the inheritance and must be kept in synch at all subsequent layers.    For this project we have come up with a clever approach of calling a base GetDo or UpdateDto making sure that the same method at each level of inheritance is called.    Each level is responsible for updating the properties at that level. This is a lot of work and not keeping it in synch can create all manner of problems some of which are very difficult to track down.    The other problem is the type of code that this methods tend to wind up with. You end up with code like this: Transferable dto = new Transferable(); base.GetDto(dto); dto.OfficeCode = GetDtoNullSafe(officeCode); dto.AccessIndicator = GetDtoNullSafe(accessIndicator); dto.CaseStatus = GetDtoNullSafe(caseStatus); dto.CaseStatusReason = GetDtoNullSafe(caseStatusReason); dto.LevelOfService = GetDtoNullSafe(levelOfService); dto.ReferralComments = referralComments; dto.Designation = GetDtoNullSafe(designation); dto.IsGoodCauseClaimed = GetDtoNullSafe(isGoodCauseClaimed); dto.GoodCauseClaimDate = goodCauseClaimDate;       One obvious problem is that this is tedious code.   It is error prone code.    Adding helper functions like GetDtoNullSafe help out immensely, but there is still an easier way. We can bypass the tedious code, by pass the complex inheritance tricks, and reduce all of this to a single method in the base class. TransferObject dto = new TransferObject(); CopyTo (this, dto); return dto; In the case of this one project, such a change eliminated the need for 20% of the total code base and a whole class of unit test cases that made sure that all of the properties were in synch. The impact of such a change also needs to include the on going time savings and the improvements in quality that can arise from them.    Developers who are not worried about keeping the properties in synch across mirrored object hierarchies are freed to worry about more important things like implementing business requirements.

• Happy Birthday, SPARC!

  - by A&C Redaktion

  25 Jahre gibt es SPARC in diesem Herbst – da gratulieren Oracle A&C und alle Partner natürlich ganz herzlich! Wir blicken zurück auf ein Vierteljahrhundert Erfolgsgeschichte:Wir befinden uns im Jahr 1987 und klobige graue PCs halten seit einigen Jahren Einzug in Büros und Privathäuser. Ein innovatives Startup-Unternehmen namens Sun Microsystems präsentiert seinen neuen Computer Sun-4, die eigentliche Sensation jedoch ist der Mikroprozessor, den die jungen Leute extra dafür entwickelt hatten: SPARC. Es handelte sich um einen extrem leistungsfähigen RISC-Hauptprozessor, der sowohl in den eigenen Workstations als auch den Servern der Sun-4-Baureihe zum Einsatz kommt. Vor allem in der Unternehmens-IT ermöglicht SPARC in den Folgejahren einen enormen Sprung nach vorn.Die weitere Entwicklung von SPARC, kombiniert mit einem Überblick über andere Meilensteine in der Geschichte der Computerwelt, finden Sie auf der Webseite "Celebrate 25 Years of SPARC Innovation".Wir springen gleich weiter in die Gegenwart, denn auch seit Sun zu Oracle gehört, hat sich so manches getan: Gerade erst hat Oracle die neue Server-Linie Sparc T4 vorgestellt – in Fachkreisen spricht man bereits von der größten Leistungssteigerung in der Geschichte der SPARC-Prozessoren.In den USA wurde das Jubiläum bereits kräftig gefeiert: Hier finden Sie Bilder vom Geburtstagsfest im Museum für Computer-Geschichte in Mountain View, Kalifornien, bei dem auch die SPARC-Entwickler Bill Joy and Andreas von Bechtolsheim zugegen waren und auch im Video SPARC-Event Highlights dreht sich alles um das Jubiläum. In der Oracle Familie gibt es 2012 noch ein weiteres Geburtstagskind: Solaris wird 20, herzlichen Glückwunsch! Das Unix-Betriebssystem, basierend auf SunOS, kam im Jahr 1992 erstmals auf den Markt. Solaris konnte seine gute Stellung seither behaupten und hat nun mit Solaris 11.1 das erste Cloud-Betriebssystem vorgestellt. Dieses überträgt die Zuverlässigkeit, Sicherheit und Skalierbarkeit des bewährten Solaris in die Cloud und bietet eine optimale Plattform für Unternehmensanwendungen.  Lesen Sie hier, was die Fachpresse über die Geburtstagskinder schreibt: ProLinux.de (SPARC) Computerwoche.de (Solaris)SearchDataCenter.de (Solaris)
