/flash_recovery_area ). ORACLE has a limit on this path, that is, it only has 2 GB space by default. It is not only the default path for archiving logs, but also the default address for backup files and flash back logs, in this way, the space used by the archive log lock cannot reach 2 GB. If the path size is not set, many systems have encountered the problem that the database cannot be archived because the archive logs are full and the space for the
