  • Performance Degradation

    Hi Friends,

    Its been a while since I posted here. I have come back today with a problem and in need of your help.

    One of our instance is giving serious performance problems. The application response degrades so badly, that it requires a complete bounce of the middle tier and database to make the system function again. I noticed that weblogic server threads gets stuck often. While starting the weblogic service, I found the following message in the weblogic.log file.
    ---------------------------------------------------------------------------------------------------
    ####<Oct 16, 2008 12:40:25 PM BST> <Warning> <Socket> <wrohstsco10> <gc3-wrohstsco10> <ListenThread.Default> <<WLS Kernel>> <> <BEA-000402> <There are: 9 active sockets, but the maximum number of socket reader threads allowed by the configuration is: 8. You may want to alter your configuration.>
    ---------------------------------------------------------------------------------------------------

    But, NativeIOEnabled is set to true in the config.xml. We are stuck and have no clue about how to proceed. Any help will be greatly appreciated.

    Hello,

    You will find the solution to this error here:

    However - this will not resolve your current performance issues. It sounds like you may have GC (garbage collection), thread blocking, agent contention and possible DB query issues - if you're having to restart all of OTM including the DB in order to resolve.
