Error description

• After applying some CICS maintenance that hits DFHMQBP0 ,
  all CICS-MQ bridge CKBP transactions fail with message
  DFHMQ0704 ... CKBP 08936 EIBRESP=16,635,328 EIBRESP2=0
  returned for EXEC CICS call. EIBFN=007F.
  .
  The trace in the dump shows no EXEC CICS commands getting
  anything other than an OK response .  Here are the last
  EXEC CICS commands for the failing CKBP task:
  .
  EXEC CICS RETRIEVE    from  cbpRetrieveParameters which is
                              a part of DFHMQBP0 (or its alias
                              CSQCBP00 )
  EXEC CICS GETMAIN     from  GetBuffer which is a part of
                              CSQCBP00 or DFHMQP0 .
  EXEC CICS ADDRESS     from  DFHMQBR9
  EXEC CICS ASSIGN      from  DFHMQERR
  .
  

Local fix

• Relink DFHMQBP0 with a job based on the following:
  //DFHMQBP0 JOB
  //* 'CALLLIBS' PROCESSING REQUIRED FOR DFHMQBP0
  //L#MQBP0 EXEC PGM=IEWL,
  // PARM='MAP,LIST,XREF,RENT,REFR'

  *                      incorrect initialisation of the WSA     *

  ****************************************************************
  Runtime errors may occur in the CICS owned MQ bridge task CKBP,
  for example:
  
  DFHMQ0704E CKBP EIBRESP=16,635,328 EIBRESP2=0
  RETURNED FOR EXEC CICS CALL. EIBFN=007F
  
  The errors may be due to incorrect initialisation of the WSA for
  DFHMQBP0 which resulted from INCLUDE statements for DFHMQP0@,
  DFHMQP2@, DFHMQR2@ and DFHMQR3@ being reordered by SMP/E at the
  time when DFHMQBP0 was link-edited.
  Only the include statement for DFHMQP0@ should be present when
  DFHMQBP0 is link-edited.
  

Problem conclusion

• The INCLUDE statements for DFHMQP2@, DFHMQR2@ and DFHMQR3@ are
  removed from the JCLIN used to link-edit module DFHMQBP0.
