Error description

• PE41527-F811
  You applied PTF UK41527 for APAR PK71609 along with other PTFs
  and FMIDs and now receive the following message each time a
  WebSphere MQSeries bridge message is processed.
  .
  DFHMQ0704E date time applid CKBR trannum EIBRESP=22 EIBRESP2=0
             returned for EXEC CICS call. EIBFN=1008.
  .
  This accompanied by an LE abend U4094 and CICS abend AMQH.
  The EIBFN 1008 is an EXEC CICS START and the EIBRESP 22 is a
  LENGERR condition. A system dump for the DFHMQ0704E message
  indicates the LENGTH on the EC START command for the CKBP
  transaction has a value of zero resulting in the LENGERR,
  however a previous AP A109 trace entry correctly traces the
  length of the MQ message headers for x'0520' bytes.
  .
  The zero length value is being set by DFHMQBR0 from field
  dfhbp020 in the C WSA ( Writable Static Area ).  The C++
  compiler generates an @@INIT@ csect to initialize the WSA.
  The Prelinker utility included the DFHMQBR0, DFHMQRB2 and
  DFHMQRB3 modules and produced output OBJ DFHMQR0@ which
  contained a merged WSA and a single @@INIT@ csect, however
  the DFHMQR2@ and DFHMQR3@ prelinker output OBJ members were
  also included in the PTF.  In this instance, due to the SMPE
  installation of the JCI6503 FMID and the UK41527 PTF, the
  sequence of the INCLUDEs were reordered and the binder used the
  @@INIT@ csect from DFHMQR3@ which did not fully map the WSA.
  .
  Only one OBJ output from the merged input XOBJ members should
  be included in the PTF which contains a merged WSA and a single
  @@INIT@ csect.

Local fix

• Relink DFHMQBR0 and ensure DFHMQR0@ is included first to binder.
  Alternatively:
  1) Remove CICS TS from SMP/E.
  2) Receive and Apply CICS TS with no additional SYSMODs
  3) Receive and Apply PTF UK41527 by itself with no other PTFs.
  :
  This allows SMP/E to not re-order the INCLUDE statements passed
  to the binder and the duplicate @@INIT@ csects will be ignored.

Comments

• This APAR is being closed with a code of RET/AU. This closing
  indicates that the Change Team has been unable to test the
  proposed fix for this APAR and that no Customer was able to test
  the fix and provide feedback within a reasonable amount of time.
  
  To ensure that only high quality fixes are distributed to all
  Customers, we require every fix to be tested either internally
  or at a Customer site which is experiencing the problem. This
  will minimize any exposure to a possible PTF error which could
  later be more detrimental to the Customer.
  
  The APAR fix is available upon application to the Change Team
  via PMR. Once the fix has been satisfactorily tested by a
  Customer experiencing the reported problem, the Change Team will
  accept a NO-DOC APAR (which must refer to this returned APAR) in
  order to provide the appropriate PTFs.
  
  If the fix does not correct the reported problem, please contact
  the Change Team via PMR with full details of the failure.
