Problem summary

  • ****************************************************************
    * USERS AFFECTED:                                              *
    * All users of the IBM z/OS Communications Server version 2    *
    * release 1 and release 2                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION:                                         *
    * Remove the SMS VIT option as a default. Given the infrequent *
    * need for the SMS VIT option during problem diagnosis it is   *
    * often not worth the CPU cost of the SMS option.              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Apply PTF.                                                   *
    ****************************************************************
    Given the infrequent need for the SMS VIT option during problem
    diagnosis, it is often not worth the CPU cost of the SMS option
    for the slight improvement in the first failure data capture.
    

Problem conclusion

  • Once this PTF is applied it is no longer necessary to manually
    disable SMS (the update from this PTF will take care of this).
    

Temporary fix

Comments
