Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Using EXEC CICS CSD API or via CECI, a GETNEXTRSRCE command
  failed with CSDERR. The following message was also given out:
   DFHCA4824 Unable to perform request - Insufficient
             function in file definition for DFHCSD.
                                                                 .
  The problem occurs for the following kind of scenario:
  CEDA DEFINE FILE(AAAAAA) GROUP(xFILE)
  CEDA DEFINE FILE(BBBBBB) GROUP(xFILE)
  CEDA DEFINE FILE(CCCCCC) GROUP(xFILE)
  CECI CSD STARTBRRSRCE GROUP(xFILE)
  CSD GETNEXTRSRCE GROUP(xFILE)
  CSD DELETE FILE  RESID(BBBBBB)  GROUP(xFILE)
  CSD GETNEXTRSRCE GROUP(xFILE)
                                                                 .
  The trace shows 'csderr' preceeded by an entry with:
  AP 04E1 FCFR EXIT - FUNCTION(READ_NEXT_SET) RESPONSE(EXCEPTION)
                      REASON(UNKNOWN_REQID_READNEXT) ..
                                                                 .
  The problem occurs only if DFHCSD is defined as an NSR file.
  (Using lsrpool 1, the problem no longer occurs).

  * PROBLEM DESCRIPTION: EXEC CICS CSD GETNEXTRSRCE gets         *
  *                      CSDERR with EIBRESP2=1 and message      *
  *                      DFHCA4824 Unable to perform request -   *
  *                      Insufficient function in file           *
  *                      definition for DFHCSD.                  *
  ****************************************************************
  EXEC CICS CSD GETNEXTRSRCE can end with CSDERR when an
  established BROWSE is ended by an implicit SYNCPOINT due to an
  intervening CSD DELETE. This can only occur when the
  CSD is using VSAM NSR; with LSR the BROWSE
  state is preserved.
  GETNEXTLIST will exhibit the same symptoms when preceded by CSD
  REMOVE GROUP.
  

Problem conclusion

• VSAM delete processing in DFHDMPCA will be changed to preserve
  the BROWSE state where VSAM non-shared resources are used with
  the CSD.
