How do you access RMAN mode in Oracle?

To enter RMAN mode, you can follow these steps:

1. Open the RMAN tool using the “rman” command in the command line. For example:

rman

1. Please input the username and password of the database administrator (DBA) if your database uses password authentication. For example:

RMAN> connect target sys/password@database

In this case, sys is the username for the database administrator, password is the administrator’s password, and database is the name of the database to connect to.

1. If your database is using operating system authentication, please execute the following command to connect to the database:

RMAN> connect target /

1. Once successfully connected to the database, you have entered RMAN mode, allowing you to execute various RMAN commands for backup, recovery, and other database management operations. For example, you can use the following command to backup the database:

RMAN> backup database;

Please note that specific commands and operations may vary depending on the database version and configuration. Please perform the corresponding operations according to your environment and needs.
