  * PROBLEM DESCRIPTION: Message DFHTS1315 with DFHTEMP full     *
  *                      containing the FROM data (DFxxxxxx)     *
  *                      from routed EXEC CICS START TERMID()    *

  * RECOMMENDATION:                                              *
  ****************************************************************
  A routed EXEC CICS START TRANSID() TERMID() FROM() command using
  the Enhanced Method (ROUTABLE=YES on transaction definition)
  stores the FROM data in Temporary Storage in a queue starting
  "DFxxxxxx".
  
  In the TOR region this queue is deleted as part of DFHALRC's
  PERFORM_PREPARE processing at syncpoint time. Likewise, the
  queue is deleted in the AOR region when the application issues
  the EXEC CICS RETRIEVE command.
  
  However if any intermediary regions exist between the TOR and
  AOR (TOR -> Region 2 -> Region 3 -> AOR) then the Bind Phase
  (DFHMRXM (MRO) or DFH62XM (APPC)) in these regions will issue
  the TS PUT and Transformer_1 in DFHXTP will issue the TS GET to
  pass the data onto the next region, but there is no delete of
  this queue in these regions.
  
  This results in a gradual increase in the use of Temporary
  Storage and may result in the Auxiliary Temporary Storage file
  DFHTEMP becoming full and issuing message DFHTS1315.

Problem conclusion

• DFHXTP has been amended so that a TS GET with the RELEASE option
  is issued when the PRIMARY_CLIENT_TYPE is not START_TERMINAL,
  i.e. not the TOR.
