About this task
The database server is online during a warm external restore.
A warm external restore involves only noncritical storage spaces.
To
perform a warm external restore:
Procedure
- To restore the storage spaces from an external backup,
use a copy command, such as cp, dd,
or tar on UNIX™ or
a file-backup program.
You must restore the storage
spaces to the same path as the original data and include all the chunk
files for each restored storage space.
- Perform a warm external restore of the noncritical storage
spaces to bring them online.
- To restore selected storage spaces and all logical logs, use
the onbar -r -e dbspace_list command.
- To restore the down noncritical storage space named dbsp1
and logical logs in separate steps, use the following commands:
- onbar -r -e -p dbsp1
- onbar -r -l dbsp1
- To restore all the noncritical storage spaces and logical
logs, use the onbar -r -e -O command.
