Error description

  • Transaction executed in TOR instead of AORs
    Scenario:
    One TOR and several AOR regions and CPSM.
    Runs a program in one of the AOR's which issues the command
    EXEC CICS START TRANSID(TEST) SYSID(TOR).
    The START request is function shipped to the TOR and
    then routed via CPSM to one of the AOR target regions.
    This works fine before PM56051 installed.
    The behavior has changed in this case that the transaction
    TEST runs now in the TOR region and is not routed to
    a target AOR.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users with PM56051 applied.              *
    ****************************************************************
    * PROBLEM DESCRIPTION: A START request is statically routed    *
    *                      from region 1 to region 2 from where it *
    *                      should be dynamically routed to another *
    *                      region. However the dynamic routing     *
    *                      program is not invoked on region 2 and  *
    *                      the transaction runs locally.           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A transaction is defined as DYNAMIC and ROUTABLE on all regions.
    A start request is issued on region 1 specifying the SYSID of
    region 2. The SYSID option causes the START to be statically
    routed to region 2, the dynamic routing program is invoked on
    region 1 for notification of the STATIC route, DYRFUNC = '3'.
    After PM56051 DFHEIIC running on region 1 ships the first 6
    bytes of the dynamic routing commarea over to region 2 to notify
    region 2 of the DYROPTER setting. On region 2 receipt of the
    dynamic routing commarea causes the incoming request to be
    treated as if it had been dynamically routed from region 1, when
    in fact it was statically routed. Dynamically routing more than
    once is not permitted, so region 2 assumes the START is no
    longer eligible for dynamic routing and, as the transaction
    definition does not specify a remote SYSID, runs the START
    locally on region 2. The dynamic routing program on region 2 is
    not invoked for route selection.

Problem conclusion

  • UK78670  UK78671  UK80342  UK81969  UK79075
    
    CICS has been changed for the reported problem so that the first
    6 bytes of the commarea are no longer sent along with the START
    request to the target region, and the dynamic routing program is
    invoked on the target region for route selection (DYRFUNC=0).
