PM14756: PRF USES EXCESSIVE CPU WHEN ORF IS INSTALLED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Program Restart Facility currently scans enqueues to determine
  whether a database is being process by IMS Online Reorg
  Facility (ORF). ORF has provided access to an interface module
  that determines whether a database is being processed by ORF
  without checking ENQ's. This APAR will utilize the new interface
  provided by ORF.

  ****************************************************************
  Program Restart Facility (PRF) uses excessive CPU when
  IMS Online Reorg Facility is installed.
  Program Restart Facility currently scans enqueues to determine
  whether a database is being processed by IMS Online Reorg
  Facility (ORF).  ORF has provided access to an interface module
  that determines whether a database is being processed by ORF
  without checking ENQs.
  

Problem conclusion

• Program Restart Facility now calls ORF interface module
  HRFOARC0 to determine whether a BMP should be paused by PRF
  until ORF has completed processing databases used by each
  BMP.
  In addition, a change to Copyright information has been made
  in each module.
  Some changes to JCLIN for module definitions was also made
  in this APAR.  A new MOD was also added:  IRTFXSR0.
  To address the JCLIN and module changes, there were changes to
  the"B" optional usermods (which can be used to have SMP copy
  the SIRTLOAD members into RESLIB).  If you use the "B" usermod,
  you must restore and reject the usermod, and then receive and
  apply the updated usermod included with this APAR.
