Error description

  • SMF 72 records contain abnormally high values for CPU time
    for Mobile transactions.  Customer was getting messages like
    "MOBILE CPU DATA EXCEEDS PRODUCT USAGE."  It was discovered
    that IMS did a Delta calculation correctly for TIMEONCP, but
    did not do it correctly for CPUTIME.

    * PROBLEM DESCRIPTION:                                         *
    * IMS is providing an incorrect value for CPUTIME for MVS      *
    * service IWM4MNTF (notify of work).                           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Install corrective for APAR/PTF                              *
    ****************************************************************
    CPUTIME contains the total CPU time for the current work
    request.  IMS is not resetting the value at each new work
    request.  Instead it contains the total CPU time since the TCB
    was created.
    
    The CPUTIME is used by the Resouce Measurment Facility (RMF) to
    monitor workload activity.  RMF is writing System Management
    Facility (SMF) record 72 subtype 3 to report the CPUTIME.
    

Problem conclusion

  • IMS is modified to calculate CPUTIME for each work request.
