Error description

  • If a DatabaseInput node encounters an exception when adding
    events to the dispatched event list or when merging new events,
    event processing may enter a loop that requires an integration
    server restart or the integration server process may abend with
    the following call stack:
    
    SqlEventCache::Mission::abort()
    SqlEventCache::Mission::Mission()
    SqlInputInterface::readData(SqlInputInterface::LocalContext*)
    ImbDatabaseInputNode::readData(ImbCallableTemplateNode::Executio
    nInstance&, int, ImbSemaphoreBase::Semaphore&, bool&,
    ImbCallableTemplateNode::OrderToken&)
    
    The injection of an event with a null key value may cause such
    an exception. This APAR will be used to improve the exception
    handling of the DatabaseInput node when handling the list of
    new events.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of IBM Integration Bus v10 and IBM App Connect
    Enterprise V11 using the DatabaseInput node.
    
    
    Platforms affected:
    z/OS, MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    If a DatabaseInput node encounters an exception when adding
    events to the dispatched event list or when merging new events,
    event processing may enter a loop that requires an integration
    server restart or the integration server process may abend with
    the following call stack:
    
    SqlEventCache::Mission::abort()
    SqlEventCache::Mission::Mission()
    SqlInputInterface::readData(SqlInputInterface::LocalContext*)
    ImbDatabaseInputNode::readData(ImbCallableTemplateNode::Executio
    nInstance&, int, ... )
    The injection of an event with a null key value may cause such
    an exception, and the following error may be seen in the system
    log:
    
    BIP2329E: An unexpected NULL value was encountered.
    

Problem conclusion

  • The exception handling in the DatabaseInput node when updating
    the list of events to be dispatched has been improved. Bad
    events will be removed from the internal list, but when an event
    cannot be processed and deleted from the events input table
    manual intervention is required to remove the event from that
    table.
