Error description

  • When an application enters a DFSTCF LOAD command via CHNG and
    ISRT calls the command may be processed by another system in the
    shared queues group. The LOAD command should only be processed
    by the local system where it is entered.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All IMS V11 users of BMP/MPP ISRT DFSTCF     *
    *                 LOAD in a Shared Queues environment.         *
    ****************************************************************
    * PROBLEM DESCRIPTION: TCO processes execute on an IMS other   *
    *                      than the initiating IMS.                *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    If a BMP or MPP (dependent region) initiates a TCO process by
    issuing an ISRT DFSTCF LOAD xxxxxxxx the LOAD may be executed
    on an IMS other than the initiating IMS.  This is because the
    DL/I Communications Call Handler routes the TCO process to the
    Shared Queues without the IMS Id to force affinity.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    DFSDLA30 is corrected to append the IMSid to TCO LTERM DFSTCF
    so the message is queued to Shared Queues with affinity.
    
    DFSCIO20 is changed to append the IMSid to TCO LTERM DFSTCF
    before issuing CQS read request.
    
    DFSSQI10 is changed to append the IMSid to TCO LTERM DFSTCF
    before issuing the CQS Inform/Uninform requests.
    
    DFSSQI30 is changed to append the IMSid to TCO LTERM DFSTCF
    before issuing the CQSQUERY request.
