Error description

• You upgraded the CICS to 5.5 and trying to test the outgoing
  web service, this is failing with the following errors .
        DFHPI0504 <applid> <tranid> The CICS Pipeline Manager
          has failed an error in the underlying transport.
          TRANSPORT: HTTP, PIPELINE: xxxxx
        DFHPI0997 <applid> <tranid> PIPELINE xxxxx WEBSERVICE
         *NONE* The error: target program unavailable or
         abended.
  .
  You are testing the same service using a web tool and it
  is working fine only issue you see is while this is being
  called from Cobol and CICS side. The actual service
  running on the server is working fine when called from the
  tool without any issue.
  .
  You also received the following error,
  DFHPG0001 An abend (code 0C4/AKEX) has occurred at offset
  X'06D6'  in module DFHPGCR.
  .
  The failing instruction is E30010000004 in DFHPGCR R720
  base at offset 6D6.
  .
  The trace shows the following exception entry,
  PG 1904 PGCR  *EXC* RECOVERY_ENTERED
          FUNCTION(PUT_CONTAINER)
          POOL_TOKEN(94254080)
          CONTAINER_NAME(DFHRESPONSE) CALLER
          (EXEC) TYPE(USER) CCSID(333)
          DATATYPE(CHAR) CONVERT(NO)
          PUT_TYPE(APPEND) CODEPAGE()
          ITEM_DATA64(00000050_41E00400,00000000_00000036)
  .
  The web service is returning its response in chunks.
  DFHWBCL receives the first chunk correctly into the
  DFHRESPONSE container. When the second chunk is received
  it needs to be appended to the container. However, this
  code path has not set up the container pool token
  correctly.  This leads to the abend in DFHPGCR.
  We need ensure that the chunked web service response is
  received correctly.

  ****************************************************************
  When a chunks response is received by DFHWBCL, a PUT CONTAINER
  to DFHRESPONSE is issued passing a pool token provided by the
  pipeline code to receive the first chunk of data.
  Any subsequent chunks received by DFHWBCL are PUT into the
  DFHRESPONSE container using an un-initialized pool token. This
  causes the EXEC CICS INVOKE SERVICE to fail with messages
  DFHPG0001, DFHPI0504 and DFHPI0997.
  
  Other possible symptoms received are DFHPI0002 X'0507',
  DFHWB0002 X'0734' and DFHPI0504.

Problem conclusion

• DFHWBCL has been changed to use the correct pool token when
  receiving chunked responses.
