• Problems with LibreOffice Impress?

  - by kkp

  I am a big fan of Ubuntu. I have recently switched from Latex to LibreOffice Impress for PPT because it seems that with Impress you can quickly create slides. I am using LibreOffice 3.4.4 OOO340m1 (Build:402) on Ubuntu 11.04. I am saving them as .ppt format. However, facing the following problems. It is really frustrating and forcing me to use Windows/MAC just for making slides. Font is changing from Arial to TimesNewRoman specifically for Tables when I reopen an Impress presentation. Tables are stretched if I reopen an Impress presentation. Impress is not allowing me to compress them (the stretched tables) and I have needed to make a fresh table. Several other modifications are reverting back when I reopen an Impress presentation. For example, the "transparency" change to the borders (e.g., for rectangular shape). Arbitrarily Impress is crashing. It would be great if someone help me to resolve these issues. Thanks.

• Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB

  - by Joe

  After trying to install both OS during 2 days, I'm confused and getting mad... I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI. What I have done: Install new SSD (Samsung 830 128GB) Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes: Partition 1: 80 GB (w7); Partition 2: 30 GB (Ubuntu 12.04 -Just / -); Partition 3: 10 GB unused (for future extesion of the other partitions) Install Windows 7 (with UEFI) in Partition 1. This create: /dev/sda1 - 100 MB for System (UEFI boot I guess) - FAT32 /dev/sda2 - 100 MB aprox. for MSR /dev/sda3 - 79.800 MB aprox. for Windows7 data In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows: Install / in Partition 2 - /dev/sda4 30 GB ext4, and in the hdd I install /home and swap. I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot). I install updates and reboot. Problem: Now just appears grub menu with Ubuntu entries and not Windows 7. Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc... but I think is not the best way to boot different OS. I've tried: sudo update-grub2 with no success. What can I do??

• Port forwarding with DNAT and SNAT without touching other packets

  - by w00t

  I have a Linux gateway with iptables which does routing and port forwarding. I want the port forwarding to happen independent of the routing. To port forward, I add this to the nat table: iptables -t nat -A "$PRE" -p tcp -d $GW --dport $fromPort -j DNAT --to-destination $toHost:$toPort iptables -t nat -A "$POST" -p tcp -d $toHost --dport $toPort -j SNAT --to $SRC $PRE and POST are actually destination-specific chains that I jump to from the PREROUTING and POSTROUTING chains respectively so I can keep the iptables clean. $SRC is the IP address I'm SNATing to which is different from the gateway IP $GW. The problem with this setup is that regular routed packets that were not DNATed but happen to go to the same $toHost:$toPort combo will also be SNATed. I wish to avoid this. Any clever things I can do?

• MySQL: how to convert many MyISAM tables to InnoDB in a production database?

  - by Continuation

  We have a production database that is made up entirely of MyISAM tables. We are considering converting them to InnoDB to gain better concurrency & reliability. Can I just alter the myISAM tables to InnoDB without shutting down MySQL? What are the recommend procedures here? How long will such a conversion take? All the tables have a total size of about 700MB There are quite a large number of tables. Is there any way to apply ALTER TABLE to all the MyISAM tables at once instead of doing it one by one? Any pitfalls I need to be aware of? Thank you

• How are cached Windows credentials stored on the local machine?

  - by MDMarra

  How are cached Active Directory domain credentials stored on a Windows client? Are they stored in the local SAM database, thus making them susceptible to the same rainbow table attacks that local user accounts are susceptible to, or are they stored differently? Note, that I do realize that they are salted and hashed, so as not to be stored in plain-text, but are they hashed in the same way as local accounts and are they stored in the same location? I realize that at a minimum they're be susceptible to a brute force attack, but that's a much better situation than being vulnerable to rainbow tables in the event of a stolen machine.

• df says disk is full, but it is not

  - by Chris

  On a virtualized server running Ubuntu 10.04, df reports the following: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.4G 7.0G 0 100% / none 498M 160K 498M 1% /dev none 500M 0 500M 0% /dev/shm none 500M 92K 500M 1% /var/run none 500M 0 500M 0% /var/lock none 500M 0 500M 0% /lib/init/rw /dev/sda3 917G 305G 566G 36% /home This is puzzling me for two reasons: 1.) df says that /dev/sda1, mounted at /, has a 7.4 gigabyte capacity, of which only 7.0 gigabytes are in use, yet it reports / being 100 percent full; and 2.) I can create files on / so it clearly does have space left. Possibly relevant is that the directory /www is a symbolic link to /home/www, which is on a different partition (/dev/sda3, mounted at /home). Can anyone offer suggestions on what might be going on here? The server appears to be working without issue, but I want to make sure there's not a problem with the partition table, file systems or something else which might result in implosion (or explosion) later.

• Consultations with ATG Development at OpenWorld 2014

  - by Steven Chan (Oracle Development)

  Our OpenWorld 2014 San Francisco conference is about six weeks away.  We have a great lineup of sessions this year.  Our EBS Applications Technology track sessions are listed here, and we'll have a more-detailed article about those soon. One of the advantages of attending OpenWorld is that you can meet face-to-face with senior staff in ATG Development.  You can use these meetings to discusss your questions, requirements, plans, and deployment architectures with us. There are several options for doing this: At general sessions: collar the speaker of your choice after his or her presentation. At the Meet The Experts sessions:  these are first-come first-served round-table discussions Setting up private meetings via your Oracle account manager The last option is best if you have lots of in-depth questions or confidential details about your implementation that cannot be discussed in front of other customers.  Many of this blog's experts, including me, will be attending OpenWorld this year.  If you'd like to meet with us privately, please contact your Oracle account manager to arrange that as soon as possible.  My calendar, in particular, is already starting to fill up.  It is often completely full by the time OpenWorld starts. See you there!

• Lost connectivity after configuring multiple network adapters on separate networks

  - by Dave Long

  I am trying to setup an Ubuntu hosting server, currently just for development, and the server has two NICs, each sitting on a different network. eth0 is on 192.168.200.* and eth1 is on 192.168.101.* and each one has a static IP. eth0 is the public facing NIC card and eth1 is strictly for internal access to the server. I initially only setup eth0 and added the eth1 card when I needed it. eth0 was working find until I added eth1, now, can't get any connectivity on eth0 unless I pull eth1 out of the box. The configuration on each system is as follows: auto eth0 iface eth0 inet static address 192.168.200.94 netmask 255.255.255.0 network 192.168.200.0 broadcast 192.168.200.255 gateway 192.168.200.253 auto eth1 iface eth1 inet static address 192.168.101.64 netmask 255.255.255.0 network 192.168.101.0 broadcast 192.168.101.255 gateway 192.168.101.254 Again eth0 worked fine until I added eth1. I have seen this happen with Windows servers if you have a Default Gateway setup for both NICs, but I am not sure if this works the same on Ubuntu. My resolv.conf file looks like so: nameserver 192.168.101.59 nameserver 192.168.101.58 domain domain.local search domain.local Per request here is the Routing table 192.168.101.0 * 255.255.255.0 U 0 0 0 eth1 192.168.200.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.101.254 0.0.0.0 UG 100 0 0 eth1 default 192.168.200.253 0.0.0.0 UG 100 0 0 eth0

• AWS RDS Mysql with benstalk Hibernate app: Character encoding issue

  - by TeraTon

  I'm running a webapp from amazon rds with tomcat 7 and spring, which uses hibernate as the persistence layer. The application and utf-8 encoding work properly on localhost, but for some reason when I deploy to amazon, the UTF-8 encoding breaks. I use mysql 5.5.27 on amazon rds and the table that we wish to update has collation set to utf8 - utf8_unicode_ci And in hibernate I have set: < prop key="hibernate.connection.charSet"UTF-8 UTF-8 characters get replaced by ??? and this is of course especially bad for passwords and usernames + email as it basically kills them. Anyone else encountered character encoding breaking when deploying to amazon?

• Most common parts of a SELECT SQL query?

  - by jnrbsn

  I'm writing a function that generates a SELECT SQL query. (I'm not looking for a tool that already does this.) My function currently takes the following arguments which correspond to different parts of the SELECT query (the base table name is already known): where order fields joins group limit All of these arguments will be optional so that the function generates something like this by default: SELECT * FROM `table_name` I want to order the arguments so that the most often used parts of a SELECT query are first. That way the average call to the function will use as few of the arguments as possible rather than passing a null value or something like that to skip an argument. For example, if someone wanted to use the 1st and 3rd arguments but not the rest, they might have to pass a null value as the 2nd argument in order to skip it. So, for general purpose use, how should I order the arguments? Edit: To be more precise, out of the query parts I listed above, what is the order from most used to least used? Also, I'm not looking for solutions that allow me to not have to specify the order. Edit #2: The "fields" argument will default to "*" (i.e all fields/columns).

• Choosing the Database Solution for Large Data Application

  - by GµårÐïåñ

  I have been tasked to write an application that will be a combination of document and inventory management in VB.net which will be used to store document images in TIFF, PDF, XPS, TXT, DOC, PPT and so on as binary data that can be retrieved for viewing, printing, and possible OCR to be searchable as well along with meta data such as sender, recipient, type of document, date, source, etc. So the table would probably be something like: DOC_NAME, DOC_DATE, NOTES, ... DOC_BINARY (where the actual document will be put inside) What my concern is finding a database solution that will not become unstable due to size restrictions, records limitations and performance. Some of the options are MS_SQL, SQL Express, SQLite, mySQL, and Access. Now I can pretty much eliminate Access right off the bat as it is just too limiting and not scalable. I can further eliminate SQL Express because of the 2 GB limit and again scalability. So that leaves me with MS_SQL, SQLite and mySQL (although if anyone has other options they think would be good as well, please feel free to share them, by no means am I set on these only). So this brings me to what you guys think is the best option for what I have described. The goal is that the data is all in one place (a single file) that will make backup and portability easier. For small volume usage, pretty much any solution will hold for a while, but my goal is to think ahead and make sure its able to withstand heavy large volume usage as well. Another consideration is also the interoperability with .NET and stability of such code to avoid errors and memory leaks. Your feedback would be greatly appreciated.

• What would cause a query being ran from SSMS on local box to run slower then from remote box

  - by Racter

  When I run a simply query such as "Select Column1, Column2 from Table A" from within SSMS running on my production SQL Server the results seems to take extremely long (45Min). If I run the same query from my dev system’s SSMS connecting to the production SQL Server the results return within a few seconds (<60sec). One thing I have notices is if the system was just rebooted performance is good for a bit. It is hard to determine a time as I have had it start running slow very quickly after reboot but at most it performed good for 20min and then start acting up. Also, just restarting the SQL service does not resolve the issue or provide a temporary performance boost. Specs for Server are: Windows Server 2003, Enterprise Edition, SP2 4 X Intel Xeon 3.6GHz - 6GB System Memory Active/Active Cluster SQL Server 2005 SP2 (9.0.3239)

• Entity Object Extension in Oracle Application R12

  - by Manoj Madhusoodanan

  In this blog I will explain how to perform Entity Object ( EO ) Extension.As a prerequisite please read my previous blog.I am doing this exercise based on PL/SQL EO. Following attributes are part of FndUserEO. Here I will add a validation to UserName attribute "Length should be > 5". Following steps need to perform. 1) Download all files of  "Entity Object Based on PL/SQL" to JDEV_USER_HOME/myprojects and JDEV_USER_HOME/myclasses.If you want to see the content of source java file decompile it and save it in JDEV_USER_HOME/myprojects. 2) Create new Entity Object XXFndUserEO as follows. Include all attributes of parent EO. 3) Add the validation code snippet to XXFndUserEOImpl.java as follows. 4) Create the substitution as follows. 5) Migrate files to $JAVA_TOP. xxcustom.oracle.apps.fnd.user.schema.server.XXFndUserEOImpl.javaxxcustom.oracle.apps.fnd.user.schema.server.XXFndUserEO.xml 6) Migrate the substitution.. 7) Bounce the server. 8) Verify the substitution has applied properly. Access Create User Page and create a User. You can see the validation message if user name length is less than 5. Give User Name as XXCUST4 and verify the table.   The FND_USER has created successfully.

• How to reformat reStructuredText?

  - by wal-o-mat

  I'm writing reST in vim, which handles line breaks for me (after 80 chars). However, since I frequently go back and edit the text before, lines get ugly again. For example, in tables, it's sometimes annoying to re-format a complete table just because you need a line break in some place. So I wish I had a program that reads my ugly-but-correct reStructuredText and outputs it nicely formatted and wrapped. I found that pandoc in.rst -w rst mostly works, but it has some drawbacks. For example :author: John Doe becomes author John Doe and title formatting is changed as well. Sadly, there seems to be no rst2rst or something similar. Does anyone have some advice?

• How do I populate multiple records of data into a PDF form like a mail-merge?

  - by user38801

  I have Acrobat Pro, and I have a PDF with a form on it. Assuming the fields in the form correspond to a data source (like rows in an RDBMS table or xml file), I want to then print multiple copies of the PDF file, with each copy having the values of a different row in the data source. It is preferable to directly interface with an actual database, rather than having to save an XML file every time I do this. If this involves programming that's cool too, I only posted here because the question didn't seem appropriate for StackOverflow. Thanks!

• Concurrent wireless and wired network

  - by Stew Megaw

  Hi, I am concerned with maintaining a wireless and wired network connection on my laptop. Basically I can change the metric on each interface so that Windows prefers one connection over the other. I am wondering is following scenario possible.... Some applications uses the wireless while other applications use the wired... I want Internet Explorer (only) to use the wireless connection while Outlook and everything else uses the wired connection. Perhaps adding some lines to the routing table might work? - Adding the ip addresses of websites I want to view via the wireless connection? Many Thanks in advance for any replies!

• Call DB Stored Procedure using @NamedStoredProcedureQuery Injection

  - by anwilson

  Oracle Database Stored Procedure can be called from EJB business layer to perform complex DB specific operations. This approach will avoid overhead from frequent network hits which could impact end-user result. DB Stored Procedure can be invoked from EJB Session Bean business logic using org.eclipse.persistence.queries.StoredProcedureCall API. Using this approach requires more coding to handle the Session and Arguments of the Stored Procedure, thereby increasing effort on maintenance. EJB 3.0 introduces @NamedStoredProcedureQuery Injection to call Database Stored Procedure as NamedQueries. This blog will take you through the steps to call Oracle Database Stored Procedure using @NamedStoredProcedureQuery.EMP_SAL_INCREMENT procedure available in HR schema will be used in this sample.Create Entity from EMPLOYEES table.Add @NamedStoredProcedureQuery above @NamedQueries to Employees.java with definition as given below - @NamedStoredProcedureQuery(name="Employees.increaseEmpSal", procedureName = "EMP_SAL_INCREMENT", resultClass=void.class, resultSetMapping = "", returnsResultSet = false, parameters = { @StoredProcedureParameter(name = "EMP_ID", queryParameter = "EMPID"), @StoredProcedureParameter(name = "SAL_INCR", queryParameter = "SALINCR")} ) Observe how Stored Procedure's arguments are handled easily in  @NamedStoredProcedureQuery using @StoredProcedureParameter.Expose Entity Bean by creating a Session Facade.Business method need to be added to Session Bean to access the Stored Procedure exposed as NamedQuery. public void salaryRaise(Long empId, Long salIncrease) throws Exception { try{ Query query = em.createNamedQuery("Employees.increaseEmpSal"); query.setParameter("EMPID", empId); query.setParameter("SALINCR", salIncrease); query.executeUpdate(); } catch(Exception ex){ throw ex; } } Expose business method through Session Bean Remote Interface. void salaryRaise(Long empId, Long salIncrease) throws Exception; Session Bean Client is required to invoke the method exposed through remote interface.Call exposed method in Session Bean Client main method. final Context context = getInitialContext(); SessionEJB sessionEJB = (SessionEJB)context.lookup("Your-JNDI-lookup"); sessionEJB.salaryRaise(new Long(200), new Long(1000)); Deploy Session BeanRun Session Bean Client.Salary of Employee with Id 200 will be increased by 1000.

• Query Performance Degrades with High Number of Logical Reads

  - by electricsk8

  I'm using Confio Ignite8 to derive this information, and monitor waits. I have one query that runs frequently, and I notice that on some days there is an extremely high number of logical reads incurred, +300,000,000 for 91,000 executions. On a good day, the logical reads are much lower, 18,000,000 for 94,000 executions. The execution plan for the query utilizes clustered index seeks, and is below. StmtText |--Nested Loops(Inner Join, OUTER REFERENCES:([f].[ParentId])) |--Clustered Index Seek(OBJECT:([StructuredFN].[dbo].[Folder].[PK_Folders] AS [f]), SEEK:([f].[FolderId]=(8125)), WHERE:([StructuredFN].[dbo].[Folder].[DealId] as [f].[DealId]=(300)) ORDERED FORWARD) |--Clustered Index Seek(OBJECT:([StructuredFN].[dbo].[Folder].[PK_Folders] AS [p]), SEEK:([p].[FolderId]=[StructuredFN].[dbo].[Folder].[ParentId] as [f].[ParentId]), WHERE:([StructuredFN].[dbo].[Folder].[DealId] as [p].[DealId]=(300)) ORDERED FORWARD) Output from showstatistics io ... Table 'Folder'. Scan count 0, logical reads 4, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Any ideas on how to troubleshoot where these high logical reads come from on certain days, and others nothing?

• Ranking tables from Excel data

  - by Joe

  Hi all (asking here because this meta question told me to). I have some data in an excel spreadsheet here. It's no more than a table with about five columns. Year Purchased Manufacturer Model Num Unit Price Total Price 2007 SMARTBOX FuturePad XP 1 £2,915.00 £2,915.00 2007 Attainment Company Inc Go Talk 9+ 1 £104.00 £104.00 2007 Attainment Company Inc Go Talk 20+ 1 £114.00 £114.00 I'd like to be able to build a 'top ten' of either manufacturers or models (and I'd like to be able to do it by either most mentioned, most sales, or highest value of sales) - but I've got no idea what the best method is in excel. Any suggestions...? The ideal output might be a set of sells that says something like Company Units A 5342 B 232 C 2 D 1

• How to really change programmatically ip address without reboot (with no connection too)?

  - by DmitryI

  Really, I tried everything, and there is no solution that works for me. WMI - everything perfect, but I can't change ip address when there is no connection. O_o Are you joking me? How can I make a connection without correct Ip-address? IPHelper - not doing anything. Just adding address to the table. Not work after reboot. netsh - the stupid way I think, but ok, if you don't no another ways you can try. Before you will know, that network adapters name can contain international characters. Did someone know how it works actually, I mean inside? Registry - working after reboot. I don't want to reboot. May be someone know how to notify about reg entries changes?

• Inventory Consignment Flow

  - by ipohfly

  Not sure whether this is the right place to ask this question, but here goes.. Currently I have requirement to add support for consignment transaction in our inventory module. I have a very limited understanding of what consignment means in inventory, i.e. Customer get stocks/products from Seller without actually buying them, the product just resides in the Customer's inventory and it's still owned by the Seller. Only when the Customer actually buy the stocks then only will the ownership of the stock is transferred. The issue is i can't imagine how the data will be presented to both the Customer and the Seller. What i know is that i would need to deduct the stock from the Seller's inventory when the Customer raise a request to get the stock through consignment, but what about the 'ownership' of the stocks/products? Does that mean i would need to create another column in my table to state that for each inventory it is owned by who? Anywhere i can get information on how i should work out an inventory module like this? Thanks.

• Do I use the FV function in Excel correctly?

  - by John

  My task: Create a table: Calculate what the revenues of e-trading will be after five years at 15 percent interest rate if we now have 15 000 EUR. Use the FV function from the Financial Group in Excel. My resolution: =FV( 15%; 5; 0; -15000). My question: Is it correct? I know the task lacks information whether the interest rate is per month or per year. I calculate it as 'per year'. My question is orientated more on the usage of the FV function. I, for example, do not understand why '-15000' and not '15000'. Also why the third parameter has to be 0? Maybe I do it wrong. Please help me solve it! Thanks in advance.

• Routing connections to passthrough a local machine

  - by xiamx

  Please tell me if what I'm trying to do is feasible. I have a router named "R" which is connected to WAN. R allows adding rules to the routing table. There are numerous of machines connected to the LAN port of R, they all have ip addresses 192.168.1.* assigned with DHCP on R. Among those machines, there's a machine C with ip address 192.168.1.100. I want all traffic of other machines in the subnet to pass-through machine C where some filtering and logging will be done. Is this possible? Is there a name for what I'm trying to do? (so i can do more googling later)

• Does my DLink DNS-323 need to reside on a "192.168.0.0/24" subnet?

  - by Raymond

  I've installed two brand new 2-tib drives in the DLink and plugged it in to my network. I set my router's static address table to include the MAC address of the device; however it doesn't ever "show up." Do I need to use the custom software to administer this device? Do I need to use a "192.168.0.0/24" network in order for this device to work (asking because it states that if DHCP isn't detected, it will default to an address in that range; and my network is not in that range).
