Error description

  • Abend0c4 in DFSYCMD0 at offset x'DCC' because Register 6 has
    an invalid address. The code is expectiong Reg 6 to contain
    the OTMA prefix address.  In subroutine Init_PRE the code
    obtained a temporary prefix address and saved the pointer to
    the temporary address in MSGPRE_Ptr. At the end of the
    subroutine, the storage was released by the pointer was not
    cleared. When the pointer is used again the abend can happen.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All IMS V11 OTMA users issuing IMS commands  *
    *                 via Commit-then-Send (CM0) protocol.         *
    ****************************************************************
    * PROBLEM DESCRIPTION: ABEND0C4 in DFSYCMD0 due to an invalid  *
    *                      message prefix pointer (MSGPRE_PTR).    *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    When an IMS command is issued from an OTMA client using CM0
    protocol, DFSYCMD0 gets a temporary block of storage to use as
    the YQAB message prefix for an insert call to the QMGR, and
    stores the address in MSGPRE_PTR. After the QMGR insert call,
    the storage is released. However, MSGPRE_PTR is not restored
    with the prefix address that is pointed to by YTIB_PREFIX_PTR,
    which can lead to an ABEND0C4.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    DFSYCMD0 was modified to restore the message prefix pointer
    after the temporary storage is released.
