• Windows 2008 R2 Task Scheduler Failure

  - by Jonathan Parker

  I have an application (.exe) which I am running via a scheduled task on Windows Server 2008 R2. The task runs fine but when the .exe returns a non-zero exit code the task is still successful when it should fail. I get this message: Task Scheduler successfully completed task "\CustomerDataSourceETL - Whics" , instance "{a574f6b4-2614-413c-8661-bc35eaeba7cd}" , action "E:\applications\CCDB-ETL\CustomerDataSourceETLConsole.exe" with return code 214794259. How can I get task scheduler to detect that the return code is 0 and fail the task?

• Should I be running my scheduled backups as SYSTEM or as the our domain admin?

  - by MetalSearGolid

  I have a daily backup which is scheduled through the Task Scheduler. It failed with a strange error code last night, but I was able to search and find a blog post with how to avoid the error in the future. However, one of his recommendations was to run the backups as the Administrator user of the domain. Since all of the files being backed up are local to this system, should I continue to have the backups run as SYSTEM? Or is it actually better to run it as a different user? I have been running these backups for well over a year now and have only had a handful of failures, but ironically when it does fail, the error code means it was a permissions issue (or so I read, this code seems to be undocumented by Microsoft). Thanks in advance for any insight into this. Might as well post the error code here too, in case anyone would like to share their insight on this as well, but I rarely ever get this error, so I don't care too much about it: 4294967294

• Starting nginx with systemctl fails, but running the command manually doesn't

• Oracle 10g for Windows does not start up on system boot

  - by Mike Dimmick

  We have an Oracle 10g Enterprise Edition installation (10.2.0.1.0) on a Windows Server 2003 virtual machine. It was initially created with Virtual Server 2005 R2 SP1 but has now been migrated to Windows Server 2008 Hyper-V. The services start on system boot, but the instance does not start up. This problem was actually occurring on Virtual Server after a migration from one server to another, but I managed to fix it then with: oradim -edit -sid ORCL -startmode auto However, this now has no effect. oradim.log (in %OracleHome%\database\oradim.log) says: Thu Jun 10 14:14:48 2010 C:\oracle\product\10.2.0\db_3\bin\oradim.exe -startup -sid orcl -usrpwd * -log oradim.log -nocheck 0 Thu Jun 10 14:14:48 2010 ORA-12560: TNS:protocol adapter error sqlnet.log in the same folder has: Fatal NI connect error 12560, connecting to: (DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleorcl)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))(CONNECT_DATA=(SID=orcl)(CID=(PROGRAM=C:\oracle\product\10.2.0\db_3\bin\oradim.exe)(HOST=ORACLE-VM)(USER=SYSTEM)))) VERSION INFORMATION: TNS for 32-bit Windows: Version 10.2.0.1.0 - Production Oracle Bequeath NT Protocol Adapter for 32-bit Windows: Version 10.2.0.1.0 - Production Time: 10-JUN-2010 14:14:48 Tracing not turned on.

The problem also occurs when stopping and restarting the OracleServiceORCL service. I've enabled SQL*Net tracing which shows: [10-JUN-2010 15:09:33.919] snlpcss: entry [10-JUN-2010 15:09:34.419] snlpcss: Unable to spawn Oracle oracle (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq))) orcl, error 2.

Right now I have a horrible hack where I've created a Scheduled Task to run oradim -startup -sid ORCL when the Administrator account logs on, and set the VM to auto-logon. I'd still like to work out why it's not working.

• Configuration Manager sub site codes

  - by NA Slacker

  I have two sub-sites set up in configuration manager. When the SCCM agent installs on the client machines within the boundaries of those sub sites they are assigned the site code of the Primary site, not the sub site code. As a result their management server remains the main server not the sub site server. I am setting up thes sub sites on cross WAN locations to cut down on traffic. What could be preventing the clients from getting associated with the proper sub site code.

• XCOPY /Exclude Directory Syntax

  - by Onion-Knight

  I'm trying to use XCOPY to copy a directory that looks like this: -MainFolder -ManyFoldersIWantToCopy -ManyFoldersIWantToCopy -... -Source Code I want to use the /EXCLUDE option to copy every folder except Source Code. I tried using the following, but I did not have any luck: xcopy "Source" "Destination" /EXCLUDE:"\Source Code\" /E /C /R /I /K /Y The error message I receive says: Can't read file: "\Source Code\". I've tried removing the double-quotes all together, using single-quotes instead, with/without the \'s, but I get the same error message. Any ideas?

• Roughly how long should an "ALTER TABLE" take on an 1.3GB INNODB table?

  - by justkevin

  I'm trying to optimize a table that hasn't been optimized in a long time. It has around 2.5 million rows with 1.3 GB of data and a 152 MB index. I started optimizing it about 15 minutes ago and I have no idea how long it will take. The server is reasonably robust (quad xeon with 4GB ram) and has a 500MB innodb buffer pool size. Should I expect this to take minutes, hours or days?

• is ksplice production ready?

  - by faultyserver

  I would be interested to hear the serverfault community's experiences with Ksplice in production. Quick blurb from wikipedia: Ksplice is a free and open source extension of the Linux kernel which allows system administrators to apply security patches to a running kernel without having to reboot the operating system. and Ksplice can, without restarting the kernel, apply any source code patch that only needs to modify the kernel code. Unlike other hot update systems, Ksplice takes as input only a unified diff and the original kernel source code, and it updates the running kernel correctly, with no further human assistance required. Additionally, taking advantage of Ksplice does not require any preparation before the system is originally booted (the running kernel does not need to have been specially compiled, for example). In order to generate an update, Ksplice must determine what code within the kernel has been changed by the source code patch. So a few questions: How has the stability been? any odd issues that you have encountered with its 'rebootless live patching' of the kernel? Kernel panics or horror stories? I have been running it on a few test systems and so far its been working as advertised, but I am interested in what other sysadmins experiences have been with Ksplice before going 'all in' and deploying this on our production servers. So, anybody using Kspice in production? update: hmm, not seeing any real activity on this question after a couple of hours (besides some kind upvotes and favs). Maybe to spark some activity I'll also ask a few more questions and see if we can get this discussion going... "If you are aware of Ksplice, is there a reason you are not using it?" "Do you feel its still too bleeding edge, unproven or untested?" "Does Ksplice not fit well within your current patch-management system?" "Do you hate having systems that have long (and secure) uptimes?" ;-)

  - by rahul

  Hi, I try to apply flattened css to xhtml (which get from websites). I am using css4j-0.12.1.jar (from http://www.informatica.info/projects/css/) to process the url html content. For a few urls the code seems to be hang. Even no exception is thrown. For a particular stylableelement or style code doesnot return any value and hangs. For a few websites code hang in, CSSStyleDeclaration.getPropertyValue(style); and for a few websites code hang in, CSSStylableElement.getComputedStyle(); I am using the latest jar. Could you please update me, is there any known issue or fix for this. I am not sure where to post this issue. If anyone knows please update me. Thanks in Advance.

• Open Source Development

  - by MA1

  I am a Fedora12(GNOME) user. I recently started development in Linux. Most of the Linux system applications/utilities are written in c/c++. The problem i am facing is that how to integrate a downloaded source code with some IDE(e.g, Anjuta etc). In simple words i want to know that, what is the best way to start development on some existing source code using an IDE. Lets take the example of GRUB2(v1.97.1). I downloaded the source code and now i want to study/customize/enhance/add new things to this code, so i want all the source files should be visible in a structural/hierarchical way for the ease of development?

• Gathering buslogic SCSI hardware and virtual machine operating system

  - by Julian

  I'm trying to use Powershell to get SCSI hardware from several virtual servers and get the operating system of each specific server. I've managed to get the specific SCSI hardware that I want to find with my code, however I'm unable to figure out how to properly get the operating system of each of the servers. Also, I'm trying to send all the data that I find into a csv log file, however I'm unsure of how you can make a powershell script create multiple columns. Here is my code (almost works but something's wrong): $log = "C:\Users\me\Documents\Scripts\ScsiLog.csv" Get-VM | Foreach-Object { $vm = $_ Get-ScsiController -VM $vm | Where-Object { $_.Type -eq "VirtualBusLogic" } | Foreach-Object { get-VMGuest -VM $vm } | Foreach-Object{ Write-output $vm.Guest.VmName >> $log } } I don't receive any errors when I run this code however whenever I run it I'm only getting the name of the servers and not the OS. Also I'm not sure what I need to do to make the OS appear in a different column from the name of the server in the csv log that I'm creating. What do I need to change in my code to get the OS version of each virtual machine and output it in a different column in my csv log file? EDIT: Here's a more in depth look at things I've tried that have all failed: Get-VM | Foreach-Object { $vm = $_ $svm = Get-ScsiController -VM $vm | Where-Object { $_.Type -eq "VirtualBusLogic" } Foreach-Object {get-VMGuest -VM $svm } | Foreach-Object{Write-output $svm >> $log} } #Get-VM | Foreach-Object { # $vm = $_ # Get-ScsiController -VM $vm | Where-Object { $_.Type -eq "VirtualBusLogic"} #| write-host $vm # | Foreach-Object { # # #get-VMGuest -VM $_ | # #write-host $vm # #get-VMGuest -VM $vm } | Foreach-Object{ # #write-output $vm.VmName >> $log # #write-output $vm.guest.VmName, get-VmGuest -VM $vm >> $log NO GOOD # # Write-host $vm.Guest.VmName #+ get-vmGuest -vm $VM >> $log # # # } # } I'm not sure why get-VmGuest fails though. I'm getting the scsi hardware, filtering the hardware to only get buslogic, and then wanting to get the operating system of just the filtered VMs. I don't see where my code fails though.

• How can I restart a service designed to run under supervise

  - by Terrence Brannon

  I have written a service designed to run under daemontools supervise. Because the run script refreshes a source code repository: git pull pod_server # serve up docs on source code via the web I desire for the script to restart every 5 minutes. The manpage for svc says that it applies all options to the service, so I thought this would work in cron: */5 * * * * svc -du etc/pod_server but it does not seem to be refreshing to source code repo with new pushes

• PowerPoint slide resolution? (Optimizing video playback)

  - by Dan

  In PowerPoint 2007, there seems to be no way of changing the resolution slide (only the aspect ratio and the output resolution can be chnaged?). If this is the case, then how do I optimize an inserted video for playback using an HD projector? Can I simply insert a video at high resolution and scale it down to fit the slide? Will these extra pixels come to use if the output resolution is high? Thanks!

• Merging Two Git Repositories with branches

  - by Joel K

  I realize there's a Stack Overflow question: http://stackoverflow.com/questions/277029/combining-multiple-git-repositories But I haven't found git-stitch-repo to be quite the tool I'm looking for. I also consider this more of a sysadmin task. How do I take code from an external repository and combine it with code from a primary repository while maintaining history/diffs and branches. Use case: An outside development team using SVN has ported to git and now wants to 'merge' their code in to the main company's git repo. I've tried subtree merges, but I lose the history. I've tried git-stitch-repo, but that process results in an entirely new repo that's missing branches. I just want to slot in some outside code as a sub-directory in our current main repo with as little disruption as possible and while maintaining the other project's history. Any success stories out there?

• Anyone know a good web-based file upload package?

  Basically, what I'm looking for is a place for either one of our end users to be able to upload a file to this package, after either receiving a code from one of our support engineers or vice-versa(our engineers upload a file and send a code/link/something to end user) I've spent a bunch of time googling this, I found this: http://turin.nss.udel.edu/programming/dropbox2/, but the code there scares me, and it also doesn't render properly using PHP 5.3(uses short tags, who knows what else.) Does anyone have any recommendations?

• Encrypt shared files on AD Domain.

  - by Walter

  Can I encrypt shared files on windows server and allow only authenticated domain users have access to these files? The scenario as follows: I have a software development company, and I would like to protect my source code from being copied by my programmers. One problem is that some programmers use their own laptops to developing the company's software. In this scenario it's impossible to prevent developers from copying the source code for their laptops. In this case I thought about the following solution, but i don't know if it's possible to implement. The idea is to encrypt the source code and they are accessible (decrypted) only when developers are logged into the AD domain, ie if they are not logged into the AD domain, the source code would be encrypted be useless. Can be implemented this ? What technology should be used?

• Faster zlib alternatives

  - by BarsMonster

  I wonder, if there are any faster builds of zlib around with more advanced optimizations? If it's possible to optimize it using SSE instructions or Intel C++ compiller, or some trick which were patented earlier (I know patents were a serious limitation during gzip/zlib development), have anyone bothered to implement that? I am especially interested in compression speed, which have a direct impact on high-performance web-services serving static & dynamic content.

  I have large amounts of data (500+ GB) stored in azure blob storage that I need to transfer to rackspace cloud files. I know it is possible to perform such a migration using the SDKs from both services, but is there a free, standard, 1-step process for doing this? I've built a POC utility but would like to avoid having to optimize it to perform the transfer within a reasonable amount of time. Thanks.

• Win Server 2008: Task Scheduler runs programs twice or late

  - by SomeName

  Hi, I need to restart a service every day. I have logon hours restricted at 3:00 am, and the server will logout existing TS connections. I have two tasks scheduled: "Daily At 3:20 am every day" "start a program" "c:\windows\system32\sc.exe stop myservice" "Daily At 3:22 am every day" "start a program" "c:\windows\system32\sc.exe start myservice" I came in today to notice that the service wasn't running. I've been digging in logs, and found these entries: For stop task, history: a) 3:29:35 am: Action Completed (sc result code 0) b) 3:20:00 am: Action Completed (sc result code 0) For start task, history: a) 3:29:35 am: Action Completed (sc result code ERROR_SERVICE_ALREADY_RUNNING 1056 (0x420)) b) 3:22:01 am: Action Completed (sc result code 0) Checking event logs shows me: a) 3:29:35 am, Application log, Source myservice, "The service was stopped" b) 3:29:25 am, System log, Source Service Control Manager, "The myservice service entered the stopped state" So, What would have caused both tasks to run at 3:29 am? Why don't I see a message from the SCM saying that the service entered the running state? Is this the preferred way to do this? Thanks!
