PQ89995: APPLICATION PROGRAM USING HSSR ENGINE RUNNING UNDER IMS V7 AND LATER DOES NOT UNLOAD VIRTUAL SEGMENTS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Application program using HSSR engine running under IMS V7 and
  later does not unload virtual segments.  Running the program
  under IMS V5, the HSSR calls are passed to the DL/I call
  handler for processing.
  

Local fix

• Change CBLTHSSR calls to CBLTDLI calls in application program.

  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  HSSR Engine erroneously retrieves no occurrence of the virtual
  logical child segment type when an user application program
  issues the HSSR calls in a DLI or a DBB region with the PSB
  in which the virtual segment is sensitive. This problem occurs
  in IMS Version 7 or later.
  

Problem conclusion

• The module FABH020 has been modified as not to skip the fallback
  to DL/I calls when virtual logical child segment type is
  sensitive in a DLI or a DBB region.
  
  After applying this maintenance, if an user application program
  issues the HSSR calls in a DLI or DBB region with the PSB
  in which a virtual logical child segment type is sensitive,
  HSSR Engine passes the calls to IMS's DL/I call handler and
  issues the following messages:
    +FABH0350E HSSR CALLS FALL BACK TO DL1 FOR NAMED DBD
               BECAUSE OF FOLLOWING PROBLEM IN DBD=DBHD009A
    +FABH0383E SEGMENTS ARE NOT ALL IN SAME DATABASE
    +FABH0351W SYSTEM PERFORMANCE WILL SLOW DOWN,
               PLEASE INFORM YOUR IMS SPECIALISTS
    +FABH0091W UNABLE TO PROCESS THE FOLLOWING PCB AS AN HSSR PCB
               (REASON: OTHER   )
    +FABH0091W  DBD=DBHD009A, PCB#=0001, PCBNAME=********
  
  If the user application program is running in an ULU region,
  no occurrence is retrieved for the virtual segment.
  
  The Unload utilities, FABHURG1 and FABHFSU, retrieve
  no occurrences for such a virtual logical child segment type.
