PH43809: REDUCE TSQ USAGE FOR SEGMENTED CONVERSE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In a complex CICS application, the amount of storage that is
  saved on TSQ during segmented converse
  can be large. While this does not have functional impact, some
  users would like to minimize this storage.
  
  The modification in this APAR reduces the amount of storage when
  possible.

  In a complex application, with many programs performing
  segmented converse, a large amount of TSQ storage is used.
  

Problem conclusion

• A new user symbolic parameter DELETETSQ is introduced in the
  build descriptor.
  
  With the value of DELETETSQ=YES,  the generated Cobol code will
  delete the previous TSQ used for any segmented Converse on
  every Converse and create a new TSQ.
  
  This may reduce storage requirement for the TSQ for the
  application in case there are multiple programs doing converse
  in the run-unit.
