STOCK(G#14) has been created but you find it contains corrupted data and
you want to restore the situation at the time of the backup so you can rerun
the production job:
REORG 'STOCK(G#13)' CATALOG GDS=REPLACE NEWDSN='*'
REORG 'STOCK(G#11)' CATALOG GDS=REPLACE NEWDSN='*(G-2)'
REORG 'STOCK(G#12)' CATALOG GDS=REPLACE NEWDSN='*(G-1)'
CA Dynam Catalog
Before: STOCK - NGEN=3 - G#14 -> G#13 -> G#12
After: STOCK - NGEN=3 - G#14 -> G#13 -> G#12
| | |
| | +-- G#11 from backup
| +---------- G#12 from backup
+------------------ G#13 from backup
Note:
• The absolute generation numbers have now all slipped forward by one. But
to the production job JCL, which uses relative generation numbers, the
situation is indistinguishable from what applied when the DUMP tape was
created.
• Again, the REORG commands are issued in an order corresponding to the
order of the files on the backup tape.
• This reconstruction could be done using more than one backup tape if that
were necessary. For more information, see the OPEN and CLOSE
commands.
RESTORE Command
The RESTORE command copies back to disk those files that were previously
dumped to tape with DYNUTIL's DUMP command.
This command has the following formats:
RESTORE VOL=volser [ OLDVOL=xxxxxx ]
[ EXCLUDE= [' file-id'|' file-id*']]
[ EXPIRE=[yy/ddd|yyyy/dd] ]
[ PERM ]
[ RETAIN ]
[ UNEXPIRED ]
[ REPLACE ]
RESTORE { 'file-id' } [ EXPIRE=[yy/ddd|yyyy/ddd]]
{ 'file-id*' } [ EXCLUDE= [' file-id'|' file-id*']]
[ PERM ]
[ RETAIN ]
[ UNEXPIRED ]
[ REPLACE ]
