Full-system restore

When your database server goes offline because of a disk failure or corrupted data, it means that a critical dbspace was damaged. The following list shows critical dbspaces:

The root dbspace
The dbspace that contains the physical log
A dbspace that contains logical-log files

When you need to restore any critical dbspace, you must perform a full system restore to restore all the data that your database server manages. You must start a full-system restore with a cold restore. See Cold, warm, or mixed restores.
