Overview
This explains the files required and important considerations when configuring a Clone DB using Cold/Hot Backup.
Method
Clone DB configuration can be carried out by choosing one of the two methods below.
Complete Recovery After Performing Cold Backup
Complete recovery is the process of applying all Online Redo contents to restore up to the most recent point in time.
For this, the backed-up datafile, controlfile, all archive log files generated after begin backup, redo log files, and passwd file are required.
The recovery process is performed by stopping the DB and copying all database-related files.
CautionEven if the DB is reconfigured through complete recovery, the moment it starts in normal mode, the existing (as-is) DB and the recovered (to-be) DB are recognized as different databases, so file compatibility is not possible.Therefore, after the DB starts following complete recovery, a new backup must be performed.
Incomplete Recovery After Performing Hot Backup
Incomplete recovery is the process of restoring only up to a specific point in time, not using Online Redo for the latest point restoration.
NoteAfter performing begin backup, copy the datafile and apply only up to the archive log files.
For this, the backed-up datafile, controlfile, archive log files up to the desired recovery point, and passwd file are required.
An advantage is that datafile copying is possible without stopping the DB, but the operating online redo log cannot be applied.
