PI19200: ACCUMULATING PGCRCB AND PGCSCB WITH REMOTE START AND DFHTRANSACTION CHANNEL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A Program builds a DFHTRANSACTION channel, including a number of
  containers. Another transaction is then started, passing the
  DFHTRANSACTION channel. Where the started transaction is defined
  as remote, the starting CICS region accumulates PGCRCB and
  PGCSCB subpool entries in the ECDSA.

  ****************************************************************
  EXEC CICS START TRANSID requests have been issued, passing a
  DFHTRANSACTION channel. The definition for the started
  transaction specifies that it is to be dynamically routed to a
  remote CICS system. DFHXTP TRANSFORMER_1 is driven to build the
  request to send to the remote system. DFHXTP then calls DFHPGCH
  to delete the local copy of the channel. The PGCH DELETE_CHANNEL
  call fails with an EXCEPTION response, reason CHANNEL_ATTACHED.
  .
  The request is routed successfully, but a failure to FREEMAIN
  the DFHTRANSACTION channel storage leads to a build up of
  storage in the ECDSA, and can eventually lead to a short on
  storage condition.
  The affected subpools are PGCHCB, PGCPCB, PGCRCB and PGCSCB.

Problem conclusion

• DFHPGCH has been updated to allow the shipped channel to be
  deleted.
