    - You can start an instance and mount a database without opening it, which you can do when you want to perform specific maintenance operations.

    - For example, the database must be mounted but not open during the following tasks:
    1. renaming datafiles
    2. adding, dropping, or renaming redo log files
    3. enabling and disabling redo log archiving options
    4. performing full database recovery

    - Start an instance and mount the database, but leave it closed by using the STARTUP command with the MOUNT option:
    STARTUP MOUNT;
