Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After migrating from CICS TS 4.2 to 5.3 that the READ for
  DFHRSTAT uses below the line SET storage.
  Because, in CICS TS 5.3, the code added to DFHFCFR caused
  pgm_data_location has been initialized to pgis_below when
  previously it was not. This field should be being initialised
  to zeros.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: GETMAINs issued from DFHFCFR that are   *
  *                      requested by DFHRXSM obtain 24 bit      *
  *                      storage incorrectly.                    *
  ****************************************************************
  When DFHRSXM is triggered to update DFHRSTAT an EXEC CICS READ
  UPDATE SET request is issued followed by a REWRITE. To complete
  this request a GETMAIN with remark FCSS SET is required. DFHFCFR
  expects to be able to ask the calling program for a data
  location, however this is not present for DFHRSXM and therefore
  the data location is not set correctly. This results in the
  GETMAIN requesting 24 bit storage (below the line) when in
  previous releases it requested 31 bit storage (above the line).
  The storage is FREEMAINed after the REWRITE which occurs
  directly after the READ UPDATE SET so the 24 bit storage is only
  held for a very brief period of time.
  

Problem conclusion

• DFHFCFR has been altered to ensure that the GETMAIN for remark
  FCSS SET obtains the correct storage for the request.
