How DBD and DDN Work

CA FAVER writes a NOTIFY.UIC command for every cluster that has DBD or DDN specified. CA FAVER opens FVRDBRC and writes the following 80-byte records:

NOTIFY.UIC DBD=(dbdname) DDN=(ddnname)  -
  RUNTIME(yydddhhmmsst)   -
  UDATA('FAVER EXPORT cluster.name')

CA FAVER creates a file containing the previous records for each cluster identified by CL=entryname, DBD=dbdname, and DDN=ddnname. The CA FAVER EXPORT jobstep must be followed by a step that executes the recovery utility (DSPURX00) to update the DBRC RECON files.

Note: For more information about DBRC, see the IBM manual IMS/VS Data Base Recovery Control Feature: Reference and Operations Manual.

Note: For more information about RESTORE procedures, see the chapter "RESTORING."

Example:

The following example creates a file containing the records for the clusters IMS.DBASE, IMSDBD, IMSDD:

EXPORT
CLUSTER
CL=IMS.DBASE  DBD=IMSDB  DDN=IMSDD
