PI81868: AN DL/I ICAL CALL NEEDS TO BE REJECTED IF THERE IS NO OUTSTANDING RESUME TPIPE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a program issues a Synchronous Callout (ICAL) and there is no
  Client available to handle the callout (no outstanding Resume
  TPIPE) then the program must wait for the full timeout value.
  It would be a performance enhancement to allow the ICAL to
  timout immediately if there is no Client to accept the callout.

  * USERS AFFECTED:                                              *

  * PROBLEM DESCRIPTION:                                         *
  * ICAL timed out with no resume tpipe                          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * INSTALL CORRECTIVE SERVICE FOR APAR/PTF                      *
  ****************************************************************
  When a DL/I ICAL call was issued from an IMS application and
  there was no active Resume TPIPE from IMS Connect, the ICAL
  call was suspended until timeout was triggered. During this
  time, the IMS dependent region sending the ICAL call was in a
  wait state.
  

Problem conclusion

•  DFSYSCP0 was enhanced to reject the ICAL call if there is no
  
   active Resume TPIPE from IMS Connect.
