Error description

  • After DB2 apar PM17542, Media Manager at z/OS 1.12 level does
    not record SMF IO counts properly. This is the companion apar to
    DB2 apar PM46045
    Media Manager will be enhanced to record SMF IO counts at the
    address space level when SMF IO counts have been inhibited at
    the DD level"

Problem summary

  • ****************************************************************
    * USERS AFFECTED: all DFSMS users at HDZ1C10 or higher         *
    ****************************************************************
    * PROBLEM DESCRIPTION: The Media Manager would only record SMF *
    *                      IO counts if the caller requested it    *
    *                      and a DD token exists.  A data set      *
    *                      allocated via dynamic allocation with   *
    *                      the S99DASUP bit set on, will not       *
    *                      generate a DD token.  If the Media      *
    *                      Manager is called to perform IO for     *
    *                      this type of data set, no SMF IO counts *
    *                      will be recorded; neither at the DD     *
    *                      level or the address space level.  The  *
    *                      intent of S99DASUP was to supress SMF   *
    *                      IO counts at the DD level, but to       *
    *                      maintain SMF IO counts at the address   *
    *                      space level.                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    

Problem conclusion

  • The Media Manager is changed to record SMF IO counts at the
    address space level when the caller requests SMF IO recording
    and there is no DD token for the data set.
    
    This apar is a companion apar to OA37361.
