APAR status

  • Closed as program error.

Error description

  • The issue here is a lack of data to sort. Much more likely to
    occur in smaller test environment than in production.
    The main issue is with the sort PIR which basically receive a
    request to sort nothing and causes a loop
    The sort routine was introduced with PTF UA62024 and the process
    of Lock Conflicts has ben introduced by PTF UA59603
    

Local fix

  • Tthe only available workaround is to recycle the XE agent
    when looping is detected
    

Problem summary

    * USERS AFFECTED: All OMEGAMON XE for IMS on z/OS v4.2.0       *
    *                 monitoring an IMSPlex.                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: High CPU detected in XE IMSPlex agent   *
    *                      KIPPLEX.                                *

    * RECOMMENDATION: Apply this PTF.                              *
    ****************************************************************
    High CPU may be seen in the IMSPlex agent KIPPLEX when
    attempting to view the Global Lock Contention workspace.
    This can randomly occur when little or no lock contention
    data is available for display for the IMSPlex view.
    

Problem conclusion

  • The code has been changed to check for and then exit when
    there is no data to display for lock contention.
