  ****************************************************************
  The Queue Space Notification Exit is not called when a BMP's
  unit of work is completed (commit point reached), by either a
  CHKPT call or the BMP's termination.This information is needed
  to keep track of Application BMP message record activity.
  The new call is implemented in IMS PK72972.
  The QCF APAR stops calling the action routines of free DRRN
  calls.
  

Problem conclusion

• Install this APAR together with IMS PK72972 for IMS V10
  or PK78154 for IMS V9.
