PH68559: TIGHT LOOP IN HFPA5SR0 NEAR OFFSETS X'4F6' AND X'584' WHEN RUNNING FPO AND FPA FUNCTIONS WITH SEGLDIST=YES SPECIFIED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Fast Path Advance Tool (FPA), Online Pointer Checker (OPC) and
  Online Reorganization Expert (OER) when SEGLDIST=YES is
  specified in the REPORT subcommand and there are compressed
  segments.
  The loop can occur when the actual data length is longer than
  the defined maximum length (due to the compression routine).
  
  Another symptom addressed: ABENDS0C4 FPXAVSM0 at offset
  x'748'.                                   ABEND0C4 S0C4
  

Local fix

• If you specify SEGLDIST=NO in the FPXIN DD, the looping module
  will not be called and the loop will be avoided.
  The result of this specification is that the Segment Length
  Distribution report will not be printed.

  ****************************************************************

  ****************************************************************
  The following issues have been addressed:
  1.The process for collecting data for the Segment Length
  Distribution Report is incorrect in FPA, FPO, and Hash Check
  support for IMS HP Image Copy when the actual segment length
  exceeds the defined maximum length due to the compression
  routine.
  2.The process for analyzing IOVF space map CI in OPC is
  incorrect when there is no IOVF data CI following an IOVF space
  map CI.
  

Problem conclusion

• 1.FPA, FPO and Hash Check support for IMS HP Image Copy have bee
  modified to output the Segment Length Distribution Report
  correctly even when there are compressed segments exceeds
  the defined maximum length.
  2.OPC has been modified to prevent S0C4 when the space map CI is
  the last CI in the IOVF part.
