    - After starting an instance, Oracle associates the instance with the specified database.

    - This is a mounted database.

    - The database is then ready to be opened, which makes it accessible to authorized users.

    - When the startup command enters the mount stage, it opens and reads the control file.

    - The control file is a binary file that tracks important database information, such as the location of the database datafiles.

    - In the mount stage, Oracle determines the location of the datafiles, but does not yet open them. Once the datafile locations have been identified, the database is ready to be opened.
