PM20161: ABEND0401 RC14 AFTER WAIT ISSUED IN DFSYOMSG IN RESPONSE SUBROUTINE 10/08/09 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• OTMA C/I client received ABEND401 RC14 ( Reg15 = x'00000014' ).
  Reason code 14 says that 'a caller who was not processingin
  task mode issued a WAIT macro with the LINKAGE=SYSTEM option.'.
  The dump list title shows 'IMS OTMA CI XCF EXIT ROUTINE DUMP'
  and the failing module points to IEAVEWAT.The OTMA C?I remains
  active after the svc dump was taken.
  Analysis indicated that we issued a WAIT in DFSYOMSG subroutine
  RESPONSE. We received the NAK before the DFS message and waiting
  for LIC ( last in chain ). Since this is an XCF processing in
  SRB mode, it seems that WAIT was allowed. The LINKAGE parm
  should probably be SVC instead of SYSTEM. Perhaps it would
  be better to call POSTPONE macro here to savethe message in
  XCF so it can be processed later.

  PM04123/UK53624 added code in DFSYOMSG Response subroutine to
  handle a NAK response with a multi-segment DFS message sent by
  DFSYTIB0 when rejecting input. The code included a WAIT macro
  with LINKAGE(SYSTEM), which was invalid, resulting in ABEND401
  RC14.
  
  Further review of all the possible DFS messages sent by DFSYTIB0
  when rejecting input showed that none of the DFS messages are
  multi-segment. The majority are keyed DFS messages, which by
  definition, are all single segment. The few non-keyed DFS
  messages are also single segment. Therefore, the code added by
  PM04123/UK53624 was unnecessary and will be removed.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  DFSYOMSG was modified to remove the unnecessary code.
