OA43590: PREDICTIVE FAILURE ANALYSIS ENHANCEMENT STDERR STDOUT FILE RETENTION *RAS APAR*

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Each PFA Check that runs at model time has some intermediary
  files that get reused.  The STDERR file in particular contains
  information that may give clues as to abnormal problems
  occurring in the JVM.  If a subsequent model happens in that
  check the data is overwritten therefore making it difficult to
  collect this data for intermittent problems.  If an error has
  occurred this apar will address retaining that data so it can be
  collected easier.

  ****************************************************************
  PFA checks create STDERR/STDOUT files at model time if they
  don't exist.  These files may have important debugging
  information in case problems occurred during modeling.  If
  information is not gathered before the next instance of
  modeling, these files get over written.  PFA should preserve
  instances of these files for a few previous modeling
  instances.
  

Problem conclusion

• PFA was enhanced to do the following:  When DEBUG is set ON
  ('DEBUG(1)') for a check, PFA will preserve up to 5 STDERR
  and STDOUT files from previous modeling instances for that
  check.  Once there is no need for preserving STDERR/STDOUT
  files, set DEBUG OFF ('DEBUG(0)') to clean up the extra files
  from check directories.
