  *                      message and ends with an abend code     *
  *                      U3100 when DFR tries to close extended  *
  *                      format OLDS after a CEC failure.        *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  If IMS is ended by a CEC failure, an EOD marker is not written
  to the opening extended format OLDS.
  Since DFR cannot correctly read the log records that are written
  to the extended format OLDS by IMS, DFR issues a MSGDFR3100E
  message and ends with an abend code U3100 when DFR tries to
  close the extended format OLDS.
  This is because DFR does not have a PASTEOD=YES flag on DCBE for
  the extended format OLDS.
  

Problem conclusion

• The following macro and module have been modified.
  *
  DFRRLGTC - A PASTEOD=YES keyword was added to the DCBEs for
             the OLDSs.
  DFRRSCDC - It was reconstructed by change of a DFRRLGTC macro.

       DFR3540E OLDS (SUFFIX=nn) WAS ACTIVE AT IMS FAILURE,
                BUT UNAVAILABLE IN DSWK
  .
       Explanation:
         ...
         It is possible that the OLDSs were not specified in the
  |      DD statements or for dynamic allocation, or that errors
  |      occurred in specified OLDSs.
  .
       System action: ...
  .
       User Response:
  |      Check if all OLDSs that were in use by IMS are correctly
  |      specified. See the OLDS Sort list to correct the error
  |      and rerun the job. If IMS DEDB Fast Recovery cannot read
  |      the OLDS because of an allocation error, an open error,
  |      a read error, or the presence of an invalid block,
  |      recover it with the Log Recovery utility if necessary.
  |      Then rerun the job with DBRC=N and AUTO=N.
