Error description

  • Customer experienced issue described by PM75701. Many PSBs
    failed scheduled with DFS0651W RC14 while the FMTLIB OLC
    COMMIT was in progess. Each failed schedule orphaned some
    PSBW storage because the path taken in DFSDBLM0 after
    DDIR1CHA is found set and OLC COMMIT active skips freeing
    PSBW storage already obtained.

Problem summary

    * USERS AFFECTED: All IMS V11 users of online change.          *
    ****************************************************************
    * PROBLEM DESCRIPTION: The PSB pool ( PSBW ) becomes full      *
    *                      ( DFS993I ) when many PSBs fail         *
    *                      scheduling with message                 *
    *                      DFS0651W ERROR 14.                      *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    When scheduling fails with DFS0651W validation error 14 the PSB
    copy is not freed from the PSBW pool.  Eventually the PSBW pool
    will fill to capacity and message DFS993I will be issued.  This
    occurs when online change is in commit phase while many PSBs are
    scheduling.

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    
     ************
     * DFSDBLM0 *
     ************
    
    Code has been added in module DFSDBLM0 after label RBLRC14 to
    set PDIRFREE in the PDIR copy when DFS0651W Validation Error 14
    occurs.  This will force the PSB to be freed from the PSBW pool.
