Veritas Cluster Weblogic Server Log File

[ronny_nch1]

Hi Guys,

I am new to this forum. Pls bear with me.
Hi All,

I am trying to change the weblogic log file to an incremental log file so that I do not needd to restart weblogic everytime the server /tmp directory reach 100% usage. I want to make it an incremental log, just like adm messages.

At the moment, operation process is written to a log file (eg: Web-scssapp_online.out) and the size is growing. The size is not reduced when I use "rm" command even though physically, the file has been removed. I guess it's because the file is still active. The size will only be reduced when I restart the weblogic.

Anyone can help me pls?
Thanks in advance.

Hi,

Could you please provide some size examples of your /tmp/.VRTSWebLogic9/*.out files.
Are you using the default ResLogLevel INFO? Maybe TRACE?
How big is your temporary folder "/tmp" ?

Regards

Manuel

Hi Manuel,

I have set the logging levels to ERROR only. The /tmp is 512Mb.

We have several application running in this server. Refer to below:

-rw-r--r--   1 root     root        477K Oct 16 11:05 Web-Ngccsdapp_online.out
-rw-r--r--   1 root     root        9.8M Oct 16 11:12 Web-ebill2app_online.out
-rw-r--r--   1 root     root        679K Oct 16 10:04 Web-ebillapp_online.out
-rw-r--r--   1 root     root         12M Oct 16 11:13 Web-etermapp_online.out
-rw-r--r--   1 root     root        1.5M Oct 16 10:57 Web-hrmsapp_online.out
-rw-r--r--   1 root     root        147K Oct 16 10:43 Web-savedapp_online.out
-rw-r--r--   1 root     root        7.4K Mar 11  2009 ebill2app_online.out

Current size is small as I just restart weblogic last night.

Hi Ronny,

The files <vcs weblogic resource name>_online.out in the /tmp directory maintain the output of the running WebLogic Server instance. The output is captured in those files for debug purposes. You can
safely remove the file once the online is successful for the WebLogic VCS resource. Regarding the
"rm" command not showing free space left, it is an expected behaviour :) The system may take some
time to fully reclaim the rm'ed space.

Hope that helps,
Satish/

Hi Satish,

Thanks for your feedback. But are you sure that "rm" commands works? Will veritas re-create the file back? I tried use "rm" command and waited for about 15 mins the space is still not reduced and i did not see any new file being created.

Hi Ronny,

The VCS agent will not re-create the file once it is removed. However the behaviour is kind of expected on Unix.
You are right, the space will not be visible till the process closes the particular file.
See the forum http://stackoverflow.com/questions/332629/rm-not-freeing-diskspace

Also did you look into the /tmp/<output file of online entry point> to see if there are any errors being thrown
from the WebLogic Server. Any particular reason why the server is being so noisy while being online?

Thanks and Regards,
Satish/

Hi Satish,

So, what's the real space consumption after the removal of the file? Is it really reduced? And can we disable this output file, meaning that I do not want Veritas to create log file at all. And also, can we change the file to an incremental log file like the dmesg?

I did checked the file content, but unfortunately I am not the application owner, it was taken care by other team. So, I don't really understand what is the error all about. Anyway, below is what I got when tail -50 the file:

There is no way to supress the creation of the output file through the agent. However you may try a work around.
As soon as online is finished, remove the output file, create a symlink with the same output file name linking
to /dev/null and see if that helps.

hi all,

Can I completely disable the log file? Meaning no log file will be created in the /tmp.

That is not possible with the current implementation.
