Perquisites for creating the standby database are:
- Oracle software must be installed on the standby server.
- Enough free space on the standby server must be available for the standby database.
- The Oracle background (cdump, udump, bdump etc ) and admin directories are created. These directories can be created by Dbvisit if you choose the option to create missing filesystem directories automatically.
Dbvisit Standby allows the following options for creating the standby database:
a) Regular file system standby database with
i) Same structure as primary database or
ii) Different structure as primary database.
b) ASM standby database (for Oracle version 10.2 and higher) with
i) Same structure as primary database or
ii) Different structure as primary database.
If the new standby database has FRA enabled, please remove all files from FRA/<unique_db_name> folder on the standby server, prior to creating the database. This is to avoid resetting the standby database incarnation triggered by the presence of old database files in FRA.
