PK85173: USING CTG WITH IPIC A DPL PROGRAM RUNS IN THE AOR UNDER TRANID CSMI WHEN DEFINED WITH A SPECIFIC TRANID (XXXX)

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible.

Error description

• Customer connects to a CICS routing region using both CICS MQ
  Bridge and CTG with EXCI. In each case, the customer define a
  DPL in the routing region to DPL to an AOR. The program for the
  DPL is defined with a specific transaction id for the mirror
  transaction name for remote attach. The mirror transaction name
  for remote attach is XXXX,(modeled after CSMI). As a result,the
  first transaction to run in the routing region is CSMI. It
  links to the program that inturn excutes the program in the
  AOR under the XXXX transaction. This works without issue when
  using the CICS MQ Bridge and CTG with EXCI. However, when I
  use CTG with IPIC, the program still runs under the CSMI
  transaction in the AOR instead of XXXX.

  ****************************************************************
  CICS transaction gateway APAR PK86772 alters the behaviour of
  the gateway when using IPIC connections to CICS. This was to
  correct the reported problem. After this APAR, CTG will only
  pass a TRANSID in the DPL request if the CTG application has
  specified one. DFHMIRS overwrites EIBTRNID with the TRANSID
  passed by CTG even if no TRANSID is passed. This will result in
  a TRANSID of nulls when the mirror task runs in the region which
  receives the request from CTG.
  

Problem conclusion

Temporary fix

• FIX AVAILABLE BY PTF ONLY
  

Comments

• DFHMIRS has been changed so that EIBTRNID is only updated for an
  IPIC attached mirror task if CTG passes an TRANSID.
  This APAR also reships the CMAC update for abend code AITM.
