PM96382: USING THE IMS PI TIME-OF-DAY FUNCTION IT SOMETIMES TAKES TWO PASSES TO LOCATE THE REQUIRED RECORD/POSITION IN THE FILE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When positioning in a log file using the IMS PI Time-of-Day
  function, two passes may be required, the first pass going to
  End-of-File before correctly locating the required
  record/position in the file.
  IMS PI uses internal indexes to facilitate its record retrieval
  and processing, when using the Time-of-Day navigate function
  it may request a record beyond EOF in which case IMS PI will
  position itself at the last record in the file. A subsequent
  Time-of-Day function correctly positions to the required time in
  the file.

  IMS PI uses internal indexes to facilitate its record
  retrieval and processing, when using the Time-of-Day
  navigate function it may request a record beyond EOF in
  which case IMS PI will position itself at the last record
  in the file. A subsequent Time-of-Day function correctly
  positions to the required time in the file.
  

Problem conclusion

• If EOF is recorded during the Navigate function check and
  the record requested was beyond the last record in the file,
  reprocess the request using the last physical record number
  to ensure the final index blocks are checked for the
  required record/position.
