One of the managed Server utilizing more space. ??

733325 Newbie
Currently Being Moderated
I have a scenario in which, one of the Managed servers (2 managed servers on different machines ) is utilizing more sapce ( physically : the size od the server/data folder is increasing every minute ) for the same application deployed on to the cluster having only 2 servers on two unix boxes.

Using weblogic server WebLogic Server Version: 10.3.0.0
2 manged servers in cluster across 2 different machines

Please provide some hint on the possible reasons that would invite this kind of server behavior. also if possible some suggestions on trouble shoot and solutions.

please find the thread stack for the server which has this issue.

    Looks like you have a WLDF (WebLogic Diagnostic Framework) collection turned on the managed server as per the thread stack.
    If you have knowingly configured WLDF, please remove it and test it.

    thanks for the reply

    Is this specifc to a server or for all the servers under the domain ? It was not configured knowingly anyway.

    Is there any way to disable it from console, rather than the config file changes?

    thanks,

    hi,

    I checked it more on the diagnostics part, and it is defenitely the diagnostics that creates this issue with one of my managed server which size upto huge 150GB under the server/data/store/diagnostics folder.

    but the other managed server diagnostics data size looks fine .


    could you please give me some poniter to get rid of this unwanted diagnostics data getting created for the managed servers.

    thanks

    We first need to understand why the diagnostic information is being collected on that particular server.
    Please check what is WLDF watch/rule or collection configured for in your environment.
    May be there is an issue on that server due to which it is collecting huge data. If I have further details, I might be able to help.

    hi Arun,


    Please find the below diagnostic module config fom the condig.xml

    <server-diagnostic-config>
    <data-retirement-enabled>true</data-retirement-enabled>
    <wldf-data-retirement-by-age>
    <name>DomainHealth_WLDFRetirePolicy_m2ap5</name>
    <enabled>true</enabled>
    <archive-name>HarvestedDataArchive</archive-name>
    <retirement-time>2</retirement-time>
    <retirement-period>6</retirement-period>
    <retirement-age>1</retirement-age>
    </wldf-data-retirement-by-age>
    </server-diagnostic-config>

    This configuration was present earlier also, but it looks like the logs statrted accumulating recently due to some other changes made to console. There is nothing coming under the WLDF console extension in server admin console.

    Other than changing the start script, will it be fine to go the file location ./server/data/store/diagnostics/WLSDIAGNOSTIC**.DAT and delete the older file while the server is running now?

    Incase not posisible , an example on the change in startscript and the config.xml will b helpful


    thanks

    The space consumption was due to the huge diagnostic logs produced due to the jdbc profiling options configured on in the administration console
  • 7. Re: One of the managed Server utilizing more space. ??
    ArunBodap Pro
    Currently Being Moderated
    I am not really comfortable suggesting you to delete the WLSDIAGNOSTIC**.DAT files for a running server.
    If you have restarted the server and the files were from the previous run then you can delete them.

    The JDBC connection pool might have been targeted to both the servers. So, then why the collection is high on only one managed server.
    Is it possible that there is some issue with the JDBC Connection Pool on that server?
    Can we check and try to fix it. I believe that will be the best way forward.
