Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of IBM Websphere Application       *
    *                 Server using Dynamic Caching with            *
    *                 replication enabled.                         *
    ****************************************************************
    * PROBLEM DESCRIPTION: Replicated objects may not be removed   *
    *                      from the Data Replication Services      *
    *                      (DRS) repository.                       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    In certain cases a build up of replication objects may lead to
    an out of memory situation when dynacache is the DRS consumer.
    

Problem conclusion

  • DRS code has been modified to release replicated objects from
    the DRS repository.
    
    This APAR is not targeted for inclusion in a 5.1.1 fixpack.
