PK83534: A NON-TERMINAL SERVICE FLOW REQUEST THAT USES MULTIPLE TERMINAL FLOWS GETS A THREAD FOR EACH TRANSACTION CAUSING CICS TO FAIL.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using a non-terminal service flow with multiple terminal
  flows accessed, a thread is created for every transaction in
  the flow.  This causes the cics region to fail.
  .
  The service flow has 10 screen transactions accessed.  This 10
  plus the related transactions remain until the service flow is
  finished.  For instance when executing 20 of the service flows
  there were over 200 threads created.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: SFR 3.1's use of BTS can generate many  *
  *                      tasks within CICS and lead to a MAXTASK *
  *                      condition being reached.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  SFR 3.1 can be inefficient in its exploration of BTS and
  underlying CICS task management. These inefficiencies have been
  addressed in SFR 3.2. However, SFR 3.2 will not run on CICS
  V3R1.
                                                                 .
  Currently, CICS 3.1 users wishing to run the SFR (Service Flow
  Runtime) are restricted in that they can only run the 3.1
  version of SFR. However, SFR 3.2 could run on CICS 3.1 if it
  were not prevented from doing so, (it checks the version and
  release of the CICS it is running on and will exit if it is not
  CICS 3.2 or higher).
  

Problem conclusion

• The SFR 3.2 entry stub module DFHMADPL has been modified to
  allow SFR 3.2 to also run on CICS 3.1.
