Restoring Data

You can use DFSMSdss to restore data to DASD volumes from DFSMSdss-produced dump volumes and to the same or different device types.

DFSMSdss allows you to perform the following restore-related tasks:

Restore an entire VSAM sphere with a single operation.
Specify whether DFSMSdss continues or cancels a restore when a permanent read error occurs.
Lock data sets on shared DASD volumes using dynamic allocation.
Rename a data set during a restore.
Redefine the block size of physical sequential, PDS, or PDSEs while recovering those data sets.
Restore data sets that have an undefined data set organization to an unlike device of larger capacity.
Specify the target status of system-managed generation data sets.
Restore a user catalog without bringing down your application program. This allows continuous applications such as DB2® and IMS™ to remain active while a damaged user catalog is replaced.
Restore data sets to system-managed volumes and non-system-managed volumes. If you have RACF® authorization, you can specify that the ACS routines be bypassed. Otherwise the ACS routines are invoked to assign SMS classes to the data sets.
