ORA-19804: cannot reclaim string bytes disk space from string limit

Cause: Oracle cannot reclaim disk space of specified bytes from the DB_RECOVERY_FILE_DEST_SIZE limit.

Action: There are five possible solutions: 1) Take frequent backup of recovery area using RMAN. 2) Consider changing RMAN retention policy. 3) Consider changing RMAN archived log deletion policy. 4) Add disk space and increase DB_RECOVERY_FILE_DEST_SIZE. 5) Delete files from recovery area using RMAN.
