This wait event only occurs when Flashback Database is turned on. A session waits for recovery writer (RVWR) to write flashback data to the flashback logs on disk because the buffers are full. Until RVWR can free up the buffers, the session may need to wait.
If this event becomes a top wait event for the database, it is typically because the file system or storage system for the Fast Recovery Area does not support enough bandwidth for Oracle to write the flashback database logs. Refer to the Flashback Database section in Oracle Database Backup and Recovery User's Guide olink:BRADVfor tuning considerations.
Wait Time: 1 second
Parameters: None
