PK46323: ABENDAXGA ALONG WITH AN ABEND0C4 IN DFHPGCR MAY OCCURR WHEN PROCESSING SEVERAL LARGE CONTAINERS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After activating channels and containers in a large production
  environment, abendAXGAs and abend0C4s start to occur.  The
  abend0C4s are occurring in DFHPGCR at +x'2C4C' while accessing
  a broken CRCB chain.
    The CRCB chain contains 0's, and PGCR assumes that during an
  append call, there will always a CSCB address.  Evidently this
  is not the case.  If there is no CSCB address, a CSCB anchor
  chain will be needed.

  * RECOMMENDATION:                                              *
  ****************************************************************
  A program passes a channel on an EXEC CICS LINK statement to a
  remote program. If the channel container is >32K including
  headers, this can occasionally produce an ABEND0C4 in DFHPGCR.
  Additional Keywords: AXGA
  

Problem conclusion

• DFHPGCR has been amended so that when it processes PUT CONTAINER
  commands, a check is made for the existence of a channel segment
  control block before the decision to perform a PUT TYPE=APPEND
  is made in routine dfhpgcr_add_container_data.
