You can use a restore request interoperability model to process a restore request in Optim™ and Optim for z/OS®.
A restore process selects data from one or more archive files and restores the data to the original or a different database. Initiate the restore process with a restore request, which specifies the archive files and defines the insert or load request used to restore the archived data
See the IBM® Optim Archive User Manual for details on the restore process.
