OA66727: PCE-COMM MAY LOOP IN HASCSCAN AFTER $TOJQ,/Q=T,/C<>,D=NEWDEST

APAR status

• Closed as program error.

Error description

• JES2 main task loop for COMM-PCE
  *$HASP9203 LONG PCE DISPATCH 583
  DURATION-000:01:46.35 PCE-COMM     EXIT-NONE JOB ID-NONE
  COMMAND-$TOJQ,/Q=T,/C<>,D=NEWDEST
  
  ANALYSIS:
  The NULL value for a limiting keyword such as FCB<> and FCB=
  is incorrectly processed.
  
  KNOWN IMPACT:
  On z/OS 3.1, a loop of the command processor in HASCSCAN may
  occur. For releases prior to z/OS 3.1, you get incorrect output
  as result of the command.
  
  VERIFICATION STEPS:
  1 - A JES2 command to set output characteristics ($TO) for one
  or more job output elements using limiting keywords with NULL
  values was issued.
  2 - In z/OS 3.1 and above loop of COMM-PCE as indicated by
  $HASP9203 LONG PCE DISPATCH which never ends.
  

Local fix

• use the long form FCB<>****, instead of the short form FCB<>,

  * PROBLEM DESCRIPTION: PCE-COMM MAY LOOP IN HASCSCAN AFTER     *
  *                      $TOJQ,/Q=T,/C<>,D=NEWDEST               *
  ****************************************************************
  Issuing $T commands with selection limiting keywords that have
  NULL values (e.g., /FCB=, /UCS<>) may cause an infinite loop.
  

Problem conclusion

• TYPE/RESTART (WARM) IPL/REQUIRED (YES) CLPA (YES)
  
  CLPA is needed only if HASCxxxx modules currently reside in
  the pageable link pack area (PLPA).
  
  The NULL value for a selection limiting keyword such as FCB<>,
  is incorrectly processed. This may result in a loop of the
  command processor or incorrect command output.
  
  Searchable keywords:
  
   - $HASP9203
   - msgHASP9203
