  *                      APAR PM40463 (PTF is UK70962).          *

  *                      MSGDFS0738I has the wrong message test. *
  *                      It says CLOSE ERROR when the actual     *
  *                      problem is that the WADS was not the    *
  *                      one in use when IMS terminated.         *
  *                      This happened because the reason code   *
  *                      used for the WADS verify error was 2    *
  *                      and when used as an index into the      *
  *                      table of text segments, CLOSE ERROR was *
  *                      the result.                             *

  - PM46954 for IMS DEDB Fast Recovery
  The value of a RLWVRFY field in a DFSFRLWA macro of IMS was
  changed into '5' from '2'. And a RLWMBE field with the value of
  '19' was added to the DFSFRLWA macro of IMS.
  DFR prevents these changes.
  

Problem conclusion

Temporary fix

Comments

• The following modules have been modified.
  *
  DFRFDLWC - This module was changed so that a reason code for a
             WADS verify error might be set to '5' instead of '2'
             and the reason code for the WADS missing record error
             might be set to '19'.
  DFRGCLSC - A WERRTYPE table was changed as follows:
             . The entry for the WADS verify error was moved to
               the 5th.
             . The entries for a dummy were added to the 18th from
               the 9th.
             . An entry for the WADS missing record error was
               added to the 19th.
