To connect to a database using RMAN, you must start RMAN and connect to the target database, which is the database to be backed up, restored, or recovered. You can connect to RMAN interactively or non-interactively.
Interactively:
1. Start RMAN and use the 'CONNECT' command, specifying the username and password of a user with the SYSDBA role.
Example:
$ rman
RMAN> CONNECT TARGET USER/
[email protected]_name;
2. Once connected, you can run RMAN commands to back up, restore, or recover the database.
Non-interactively:
1. Start RMAN using the 'RMAN TARGET' command, specifying the username and password of a user with the SYSDBA role.
Example:
$ rman target USER/
[email protected]_name
2. Once connected, you can run RMAN commands to back up, restore, or recover the database.
