PK66994: PROVIDE DEFAULT DFSMSCE0 PROGRAM SO THAT IMS V8, V9 AND V10 RECOGNIZES WLR'S PRESENCE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If the WLR user does not provide the DFSMSCE0 MSC User exit (IMS
  V8, V9 and V10) - or any of the DFSMCTR0, DFSNPRT0 or DFSCMPR0
  exits (IMS V8 and IMS V9 only) - IMS WLR will appear to
  initialize correctly during IMS start-up, but the WLR code will
  never be executed as IMS will not recognize that WLR is active
  without one of these exits. Attempts to turn the product TRACE
  ON will result in the WLR Control blocks being set correctly,
  though no trace records will ever be produced.

  Provide default DFSMSCE0 program so that IMS V8, V9 and V10
  recognize WLR's presence. If the WLR user does not provide
  the DFSMSCE0 MSC User exit (IMS V8, V9 and V10) - or any of
  the DFSMCTR0, DFSNPRT0 or DFSCMPR0 exits (IMS V8 and IMS V9
  only) - IMS WLR will appear to initialize correctly during
  IMS start-up, but the WLR code will never be executed as IMS
  will not recognize that WLR is active without one of these
  exits. Attempts to turn the product TRACE ON will result in
  the WLR Control blocks being set correctly, though no trace
  records will ever be produced.
  

Problem conclusion

• New module IWXMSCE0 has been created to ensure that IMS
  recognizes WLR's presence in this situation.
  After applying this APAR/PTF, IMS needs to be stopped and
  restarted (WARM start is sufficient)
