I guess (because of ORA-19809), it's a problem with a full flashback recovery area, which is here the archive log destination. This happens if the flashback area never releases space, because of a bad configuration. Recommendations from documentation are:
Make more disk space available, and increase DB_RECOVERY_FILE_DEST_SIZE
to reflect the new space.
SQL> alter system set DB_RECOVERY_FILE_DEST_SIZE= <new size>;
- Use the command BACKUP RECOVERY AREA, to back up the contents of the
Flash Recovery Area to a tertiary device such as tape.
Example:
RMAN> backup recovery area device type 'sbt_tape';
- Delete unnecessary files from the Flash Recovery Area using the RMAN delete
command.
NOTE: If a host operating system command is used to delete files,
then the database will not be aware of the resulting free space. Run
the RMAN CROSSCHECK command to have RMAN re-check the contents of the
Flash Recovery Area and identify the deleted files. Afterwards run DELETE
EXPIRED to remove deleted files from the RMAN repository.
- You may also need to consider changing your backup retention policy
Example :
RMAN> configure retention policy to recovery window of 30 days;
'alter system set DB_RECOVERY_FILE_DEST_SIZE= <new size>;' will only help you for a while, if you don't configure properly the flashback area.
