Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of the default messaging provider for *
    *                  IBM WebSphere Application Server            *
    *                  Version 6.1 and Version 7.0                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: Excessive creation and deletion of      *
    *                      workspaces when sending messages over   *
    *                      an inter-bus link, or via an            *
    *                      intermediate messaging engine           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Large delays and WKSP0006E exceptions might occur when sending
    messages to a destination, when there are multiple messaging
    engines in a bus, or an inter-bus link connecting buses.
    
    The cause of the delays and exceptions is excessive use by the
    messaging engine of an interface to inspect the configuration
    on the node, to determine the name of a messaging engine from
    its UUID. This information is being gathered regardless of
    whether trace is enabled or not, but only output to trace when
    SIBMessageTrace=all trace is enabled. Even when trace is
    enabled, the information is noncritical for problem diagnosis.
    
    Each time the interface is used for this unnecessary activity,
    a new workspace is created by the configuration service, which
    involves significant disk I/O, and throws exceptions when
    multiple attempts to create workspaces occur concurrently
    (within the same millisecond).
    

Problem conclusion

  • The fix for this APAR removes the unnecessary lookups in the
    configuration within MessageItem.eventPostCommitAdd, when a
    message is sent from one messaging engine to another (within a
    bus, or over an inter-bus link).
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 6.1.0.37 and 7.0.0.15.  Please refer to the
    Recommended Updates page for delivery information:
