Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 for z/OS RRSAF users.                *
    ****************************************************************
    * PROBLEM DESCRIPTION: ABEND0C1 in DSNXEEZ when a DB2 SQL      *
    *                      COMMIT or SQL ROLLBACK has been issued  *
    *                      while the RRS Coordinator was not       *
    *                      available.                              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    During execution of a DB2 SQL COMMIT or SQL ROLLBACK DB2 will
    check with the RRS Coordinator to see if there are other
    interested Resource Managers. If at the time the check
    occurs the RRS Coordinator has gone down, DB2 can be
    referencing residual RRS related structures.
    

Problem conclusion

  • DB2 has been updated to check whether the z/OS RRS structures
    are still valid. If the structures are no longer valid, DB2 will
    assume z/OS RRS coordination is required with other Resource
    Managers and exit the SQL COMMIT or SQL ROLLBACK with no
    further action.
