Hi All,

We have noticed OPMN crash and restart, while investigating, Noticed Biserver1 log (managed server log) there were some error STUCK

From Apr 12, 2016 8:15

we noticed OPMN started crashing one after one and restarted after some time.

does STUCK threads crash OPMN or Managed seeerver.

I checked all the logs, noticed no Errors which might caused the Crash.

Please provide me some details on this.

Thanks

    What is the exactly OBIEE version you are using?

    What is the oracle.bi.presentation.sawconnect.ConnectionPool.MaxConnections value of the parameter in file $middleware_home\user_projects\domains\bifoundation_domain\config\fmwconfig\biinstances\coreapplication\bridgeconfig.properties?

    Add oracle.bi.presentation.sawconnect.ConnectionPool.MaxConnections=512 to that file and see if that works.

    Ref: OBIEE 11g: Error: "<BEA-000337> <[STUCK] ExecuteThread: '7' for queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "1,276" seconds working on the request" and BI Server Crashes (Doc ID 1495747.1)

    Add oracle.bi.presentation.sawconnect.ConnectionPool.MaxConnections=512 you still get the same issue?

    Just a thought but could the threads be stuck because OPMN crashed and not the cause of the crash itself?
    Also, what is your Java Heap Size set to?
