It stores the metadata about the target database and its backup and restores operations information. RMAN also stores information about its own configurational settings, the target database schema, etc. RMAN repository information can be viewed with the help of LIST, SHOW, and REPORT commands. RMAN repository data is stored in the control file of the target database. The initialization parameter, CONTROL_FILE_RECORD_KEEP_TIME, is responsible for controlling the time for how long the backup records are to be kept in the control file after which those records can be re-used to hold information about more recent backups. However, the repository can also be kept in a recovery catalog as mentioned earlier.
