ORA-00257: Archiver error. Connect internal only, until freed
What it means
The archiver cannot write archived redo logs, usually because the archive destination or the Fast Recovery Area is full; DML stops.
How to fix it
Back up and delete archived logs with RMAN (not with OS commands), or raise DB_RECOVERY_FILE_DEST_SIZE. Check v$recovery_area_usage.
