Using the REORG command, restore the (G#11) version from the tape in its
original sequence:
REORG 'STOCK(G#11)' CATALOG GDS=ORIGINAL (GDS=ORIGINAL optional) CA
Dynam Catalog
Before: STOCK - NGEN=3 - G#13 -> G#12 -> G#11
After: STOCK - NGEN=3 - G#13 -> G#12 -> G#11
|
+-- G#11 from backup
Note that if G#14 had already been created, DYNUTIL would issue a message
that the requested target file was no longer current, and no processing would
take place.
Using the REORG command, restore all versions from the tape in their original
sequence:
REORG 'STOCK*' CATALOG GDS=ORIGINAL (GDS=ORIGINAL optional) CA
Dynam Catalog
Before: STOCK - NGEN=3 - G#14 -> G#13 -> G#12
After: STOCK - NGEN=3 - G#14 -> G#13 -> G#12
| |
| |
| +-- G#12 from backup
+---------- G#13 from backup
Note that G#14 is not processed because it is not found on the tape, and
G#11 is bypassed because it is no longer current.
Using the REORG command, restore the (G#12) and (G#13) versions in
reversed sequence:
REORG 'STOCK(G-1)' CATALOG GDS=REPLACE NEWDSN='*(G-2)'
REORG 'STOCK(G-2)' 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#13 from backup
+---------- G#12 from backup
Note that the REORG commands could not be given in the reverse order unless
the tape were closed and reopened between them; DYNUTIL only searches the
tape in the forward direction.
