RECOVER command

The RECOVER command causes a recovery task to be started for the data store file named on the command. The recovery task attempts to repair a corrupted data store file by exporting it, reallocating and initializing it, and restoring it. The restore operation rebuilds the index information, the data most likely to be corrupted in a damaged file. The recovery is not guaranteed to be successful, however; some severe forms of data corruption are unrecoverable.

Important: The content in this section was created for and applies to the original persistent data store, referred to as PDS V1. A new PDS version (referred to as PDS V2) now exists. PDS V1 will eventually be deprecated.

Syntax

RECOVER       FILE=DSN:dsname

where

dsname: Specifies the physical name of the data set to be recovered.

RECOVER logic

This code quiesces the data set and closes the file. Information is set up to request an ARCHIVE, INIT, and RESTORE operation to be performed by the maintenance procedures. An SVC 34 is issued for a START command on KPDPROC1 (or its overridden name). The command exits to the caller, and the data set is unusable until a RESUME command is executed.
