Use continuous log restore to restart a log restore with
newly available logs after all currently available logs have been
restored. For more information, see Continuous log restore.
To
configure continuous log restore with ontape:
Procedure
- On the primary system, perform a level-0 archive with the ontape
-s -L 0 command.
- On the secondary system, copy the files or mount the tape
(as assigned by LTAPEDEV) and perform a physical restore with the ontape
-p command.
- Respond to the following prompts:
Continue restore? Y
Do you want to back up the logs? N
Restore a level 1 archive? N
After the physical restore
completes, the database instance waits in fast recovery mode to restore
logical logs.
- On the primary system, back up logical logs
with the ontape -a command.
- On the secondary system, copy the files or
mount the tape that contains the backed up logical logs from the primary
system. Perform a logical log restore with the ontape -l
-C command.
- Repeat steps 4 and 5 for all logical logs that are
available to back up and restore.
- If you are doing continuous log restore on a secondary
system as an emergency standby, run the following commands to complete
restoring logical logs and quiesce the server
- If logical logs are available to restore, use the ontape
-l command.
- After all available logical logs are restored, use the ontape
-l -X command.
