PM75335: TRANSACTION EXECUTED IN TOR INSTEAD OF AORS AFTER PM56051 INSTALLATION 12/10/24 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

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).
