Auxiliary Cloning

The document outlines the configuration and cloning process for Oracle databases named 'dev' and 'maths', detailing parameters such as file destinations, memory settings, and control files. It includes commands for creating necessary directories, starting the database instance, and using RMAN to duplicate the target database. The cloning process involves restoring datafiles, performing media recovery, and resetting database parameters for the new instance.
