Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Here is customer's environment:
  AOR      ----MRO---------> TOR    ---LU6.1------->  IMS
                   function ship -->       function ship -->
  STAR TRANSID(TRN1)
  PROTECT/NOCHECK
  DYNAMIC(YES)
  ROUTABLE(YES)              ------> ATNI rc0C0B --------> DFS2042
  An abend ATNI RC0C0B is detected on the region (TOR) that propag
  ate a START TRANSID(TRN1) to an IMS system. On IMS the start
  fails with error message DFS2042 due to an invalid FMH sent:
  Byte 5 of the FMH6 ,x'40' (FHMXRPLY), is rejected because not
  supported.
  Problem happens if the START issued into AOR region is PROTECT
  NOCHECK and the transaction (TRN1) is defined DYNAMIC(YES) and
  ROUTABLE(YES). No problem is found if the started transaction is
  statically defined into the AOR region .

  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: The PROTECT option on a START command   *
  *                      is lost during function shipping to an  *
  *                      IMS/DC region, leading to MSGDFS2042    *
  *                      due to an invalid FMH sent.             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  An EXEC CICS START with options PROTECT and NOCHECK is function
  shipped from one CICS region to another CICS region over an MRO
  connection. It is then function shipped to an IMS region over
  an LU61 link.
  As the transaction is marked as DYNAMIC and ROUTABLE it uses the
  enhanced routing method for the START request.
  The START is incorrectly deferred (eiic_deferred_rout) and a
  CDFS transaction is attached to ship the request.
  The IMS start fails because no definite response (RQD2) has
  been requested. The PROTECT option should cause the request to
  be function shipped with RQD2, but because the START has been
  deferred the PROTECT option has not been propagated.

Problem conclusion

• DFHEIIC routine check_dynamic_start has been changed so
  that the PROTECT option does not automatically result in a
  deferred start.
