PM86872: ALLOW U240 TIMEOUT FOR LONG RUNNING EXTERNAL SUBSYSTEM CALLS.

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• This service provides the ability to allow an ABENDU0240 Timeout
  condition to be issued to terminate IMS applications that are in
  long running External Subsystem calls.

  dependent region start up) may not be terminated with ABENDU240
  while in a long running call to an External Subsystem.
  

Problem conclusion

Temporary fix

Comments

• ABENDU240 will now be enforced in IMS dependent regions that
  are running in an External Subsystem (ESS) when time expires
  using IMS Timing Services.
  
  IMS timing is established in BMP Regions using CPUTIME= and
  the STIMER= parameters on the BMP startup.
  
  MPP regions establish timing using the STIMER= parameter on
  the MPP startup and the PROCLIM= parameter of the TRANSACT
  macro for the transaction being processed by the MPP.
  
  Prior to this change, ABENDU240 was delayed until after the
  External Subsystem returned to IMS. Now when the Timeout
  routines detect processing in an ESS, they will schedule
  ABENDU240.
  
  It should be noted:
  IMS establishes a time limit using the STIMER macro and the
  TASK parameter to indicate that the time interval is only
  decreased when the associated task is running. Any ESS that
  WAITs or SUSPENDs the IMS dependent region will therefore not
  decrease the time interval during these events and will not
  drive STIMER exit routines to issue abends.
