web publisher view, edit slow performance

Pradeepgaddipati

Hi All,

   In our application while view, edit and publish content in webpublisher performance is very slow. ( we are using Documentum 5.3 SP22, webpublisher 5.3.0.217 SP2  )

   After Docbase restart the application is working as expected for couple weeks or less than one month, after that same poor permance while view, edit the        content.

    I checked the logs like docbase.log,docbroker.log and kdm3startManagedWebLogic.out(weblogic server) log. no errors in docbase and docbroker log but some errors in kdm3startManagedWebLogic.out file

• 'weblogic.kernel.Default'; MSG: Unable to obtain a lock on the session; ERRORCODE: ff; NEXT: null java.lang.NullPointerException

• java.lang.NullPointerException  (Cause : if we want to use any variable and which is null . we will get this type of errors)    (WcmAsyncTaskManager.java:331)

• java.net.SocketException: Broken pipe (errno:32)
  at java.net.SocketOutputStream.socketWrite0(Native Method)
• java.io.IOException: A complete message could not be read on socket: 'weblogic.servlet.internal.MuxableSocketHTTP@1383b2a - idle timeout: '30000' ms, socket timeout: '5000' ms', in the configured timeout period of '60' secs

Can you please tell me why

     1 .     why the Docbase is hanging and need to restart ?

     2.      is there any relation with weblogic errors for Docbase hang or slow perfomrance

   

Thanks in advance

Thanks,

     1 .     why the Docbase is hanging and need to restart ?

- Sounds like there is a memory leak.  This is why when you restart content server, it works fine for awhile.  Keep in mind you are using a very old version of Documentum.  Plus, you are not even on the most current service pack for v5.3, which by the way is no longer officially supported.

     2.      is there any relation with weblogic errors for Docbase hang or slow perfomrance

- Verify in your release notes that you are using the Java version that is in the release notes for Webpublisher.  Also verify that the JRE for your browser is also the same version.  Using newer JRE can cause problems.
