Problem summary

  • ****************************************************************
    * USERS AFFECTED:  WebSphere eXtreme Scale users that use      *
    *                  dynamic maps created from a template.       *
    ****************************************************************
    * PROBLEM DESCRIPTION: Number of entries in the dynamic map    *
    *                      do not match between the primary and    *
    *                      the replica.                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    An ordering problem on getting the next revisions and the maps
    to query replication was inverse of what it should have been.
    This problem was corrected so that tranasctions that involved
    newly created maps were not missed.
    

Problem conclusion

  • An interim fix for this problem is available for 8.5.  The fix
    is also included in the 8.6.0.2 fixpack.
