Which initialization parameter determines the number of days before RMAN information in the control file can be overwritten?
Because the control file stores backup, recovery, and restore information, the amount of information stored can become rather large if there are frequent backups and a large target database. To limit the amount of information stored, you can alter the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter to specify the number of days that RMAN maintains backup, recovery, and restore information. When using CONTROL_FILE_RECORD_KEEP_TIME, be sure the recovery catalog is resynched more often than the overwrites to the control file.
