Recovering Damaged Restart Data Sets

If a restart data set is damaged, delete it and then copy and rename the corresponding backup restart data set to create a replacement data set.

Use the following sample JCL in the #RCOVRDS member of the hlq
.SAMPLIB library to delete the damaged restart data set and copy the backup:

//*-------------------------------------------------------------------*
//* REPLACE THE FOLLOWING ITEMS WITH PROPER INSTALLATION VALUES
//* 1. JCL DATA SET NAMES
//* 2. IDCAMS COMMAND SPECIFICATIONS
//* 3. REPLACE ???? WITH YOUR LOGGER NAME. USING THE LOGGER NAME AS A

//*    DATA SET BELONGS TO WHICH LOGGER.

To recover damaged restart data sets:

Make a working copy of the sample #RCOVRDS member, and edit the copy as required.

The following table describes the JCL statements in this member.

JCL Statement	Description
EXEC	Specify the IDCAMS program.
SYSPRINT DD	Specify the output data set for MVS system messages.
SYSIN DD	Specify the IDCAMS commands DELETE, SET, DEFINE, and REPRO. For more information about these IDCAMS utility commands, see your IBM documentation.
PRILOG DD	Specify the log data set names you used when you created the log data sets. You created these data sets during installation.
