Problem summary

  • ****************************************************************
    * USERS AFFECTED: All OMEGAMON XE for IMS on z/OS V4.2.0       *
    *                 and V5.1.0                                   *
    ****************************************************************
    * PROBLEM DESCRIPTION: The TEP IMS Local Lock Conflicts        *
    *                      workspace may be empty when Program     *
    *                      Isolation is used and lock conflicts    *
    *                      exist.                                  *
    ****************************************************************
    * RECOMMENDATION: Apply this PTF.                              *
    ****************************************************************
    When Program Isolation is used and lock conflicts exist, the
    XE collector incorrectly accesses the IMS REQBLK and QCB
    control blocks when they reside in the DLI SAS address space.
    As a result, the TEP IMS Local Lock Conflicts workspace may
    be empty or a S0C4 abend could occur.  Classic properly shows
    the lock conflicts.
    

Problem conclusion

  • Correct the XE collector to properly access the IMS control
    blocks that populate the data for lock owners and waiters.
