Introduction › The CA FAVER System › Restore

Restore

Restore is invoked by the execution of the GVRESTOR program to process a file created by GVEXPORT. GVRESTOR control statements provide the following:

1. Method by which the input file is searched for clusters to be restored
2. Identity of the catalog(s) in which clusters are to be defined
3. Ability to name clusters to be restored, excluded, or processed by a user exit, or to be defined with new AMS parameters

Three methods are provided for searching the export file:

CATALOG

Restore all clusters exported from a specified catalog or catalogs, optionally excluding named clusters.

VOLUME

Restore all clusters exported from designated volumes, optionally excluding named clusters.

CLUSTER

Restore only the clusters whose names are specified.

A restore can be completely automatic. Since the catalog information for a cluster has been maintained on the export file, CA FAVER can create an empty cluster into which the data can be restored by invoking an IDCAMS DELETE and DEFINE.

During an automatic define, any AMS DEFINE CLUSTER parameters can be provided to replace those of the original cluster. The autodefine can be bypassed and the restore directed to a previously defined empty cluster or CA FAVER can open a reusable cluster with the reset option, eliminating IDCAMS processing.

A user exit facility is provided. You can examine each record before it is restored and decide whether to restore it, delete it, modify it, or insert new records.

The printed output of RESTORE includes the names of clusters restored, record counts, and all IDCAMS output.
