Error description

  • Customer have migrated their development cell from zWAS/WCG 6.1
    to Version 8 and noticed that two DB2-LREE-Tables grow and grow.
     Seems, there is no cleanup of these tables:
    
    
    [LREE].CHECKPOINTREPOSITORY - no cleanup (after job ends)
    [LREE].POJOSTEP - no cleanup (when job removed via JMC/lrcmd)
    
    In backward compatibility mode, POJOSTEP entries are not being
    clean up when the application throws exception before the
    endpoint container invokes application's processJobStep().

    * RECOMMENDATION:                                              *
    ****************************************************************
    POJOSTEP entries are not cleaned up because the application
    exception is propagated to the caller and the clean up routine
    is not called.
    

Problem conclusion

  • The container needs to catch the application exception in this
    path and execute the clean up routine.
    
    The fix for this
    
    APAR is currently targeted for inclusion in fixpack 8.0.0.4.
