Error description

• When dynamic transaction routing an inbound Web service from a
  CICS TS V3.2 region (listener) to CICS TS V3.1 (AOR), the CICS
  TS V3.1 region produces the following messages:
  ===
  DFHAP0002 IYCQST73 A severe error (code X'4E19') has occurred in
  module DFHAPCR.

  The CICS TS V3.2 system issues the following message:-
  DFHPI0997 20/07/2007 17:28:38 IYCQST63 TRA3 ........ The CICS
  pipeline manager. The CICS pipeline manager has encountered an
  error: target program unavailable
  
  The trace of the CICS TS V3.2 region shows several exception
  trace entries ending with
  AP 4E01 APCR  EXIT  IMPORT_ALL/EXCEPTION  DATA_ERROR
  
  This is because a DSECT has been invalidly changed in CICS TS
  V3.2 so that it is 4 bytes out of step with the CISC TS V3.1
  DSECT. This results in a word being treated as a data length
  indicator when it is actually the first word of the data itself.

  ****************************************************************
  Attempting to route a web services request from a CICS TS 3.2
  region to a CICS TS 3.1 region fails. This is because one of
  the requeststream headers has changed length by 4 bytes. The
  effect of this is that the CICS TS 3.1 region receives invalid
  data and attempts to receive more data than are being sent by
  the CICS TS 3.2 region. This results in unpredictable failures
  on both sides. Typically, it is seen as a TC_ERROR response
  from DFHZARQ on the CICS TS 3.2 region and a
  BAD_RESPONSE_TO_DOMAIN_CALL IMPORT_ALL on the CICS TS 3.1
  region.

Problem conclusion

• DFHPIIS has been changed so that the requeststream headers
  have the correct length.
