APAR status

  • Closed as program error.

Error description

  • If DB2 is brought down forcefully or fails, and is then
    restarted, some URs that were not yet completed may be marked
    "in doubt".  If such a UR is subsequently processed with the DB2
     -RECOVER INDOUBT command, and is ROLLedBACK, it is possible
    that a UR Control record sequencing error will be raised by IIDR
     CDC for z/OS, issuing message CHC1528E and ending the
    subscription.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of IIDR CDC for z/OS.                  *
    ****************************************************************
    * PROBLEM DESCRIPTION: In-doubt URs should be resolved for     *
    *                      replication based on how they were      *
    *                      resolved in the DB2 Log.  No external   *
    *                      configurable setting should be used.    *
    ****************************************************************
    * RECOMMENDATION: APPLY CORRECTIVE SERVICE                     *
    ****************************************************************
    
    The current approach to resolving in-doubt URs is insufficient
    and can lead to desynchronization of source and target tables.
    

Problem conclusion

  • In-doubt URs will be held in the Staging Space until a logged
    resolution (COMMIT or ABORT) is encountered and used to dispose
    of the UR.
