ORA-00257 means Oracle encountered an error archiving a redo log. The leading cause is a full archive destination, but Oracle also identifies failure of a destination marked MANDATORY. The alert log and trace files reveal which problem occurred; diagnose that before deleting files or changing archive settings. If the failure remains unresolved, Oracle warns that transaction execution can stop.
What ORA-00257 means
Oracle’s error reference describes ORA-00257 as: “The archiver process received an error while trying to archive a redo log.” The message says to connect as SYSDBA only until the problem is resolved. Oracle identifies an archive-destination device without space as the most likely cause, but a failed MANDATORY destination is another possibility. A full disk is therefore a useful first suspicion, not a diagnosis. Oracle Database Error Messages: ORA-00257
Redo logs record database changes. When Oracle cannot archive a redo log as required, it can eventually stop executing transactions. Oracle’s archived-redo guidance also warns that a disk-full error during archiving can cause a fatal error and the database to stop responding. Oracle Database 19c: Managing Archived Redo Log Files
Diagnose the failed archive destination
- Connect with administrative privileges. The ORA-00257 message directs administrators to connect AS SYSDBA while the issue is unresolved.
- Inspect the alert log and trace files. Oracle specifically directs administrators to these records for the accompanying archiver error. Use the detailed error to identify the destination and failure rather than assuming storage is full. Oracle Database Error Messages: ORA-00257
- Check the destination’s state. Oracle Database 19c documents destination status attributes including validity, enablement, and activity; destination information is available through
V$ARCHIVE_DEST. Check the destination implicated by the error and whether it is required. Oracle Database 19c Reference: V$ARCHIVE_DEST - Determine what kind of destination failed. Oracle Database 19c supports local targets such as filesystem paths, ASM disk groups, and the Fast Recovery Area (FRA), as well as remote destinations configured with a service for a standby database. Multiple destinations may be configured, so establish which one failed and whether it is MANDATORY. Oracle Database 19c: Redo Transport Services
- Look for a specific FRA-limit error. ORA-19809 means the limit for recovery files set by
DB_RECOVERY_FILE_DEST_SIZEwas exceeded. That identifies an FRA limit problem; it does not establish that every ORA-00257 is an FRA problem. Oracle Database Error Messages: ORA-19809
Choose a correction that matches the cause
Once the alert log and destination status identify the failure, address that specific condition. If the destination is unavailable or invalid, restore its availability or correct its configuration. If it is full, make room or provide capacity while protecting the database’s recovery requirements. Oracle’s documentation lists several approaches for recovery-area pressure; they are alternatives to evaluate, not commands to apply indiscriminately.

If the Fast Recovery Area limit was exceeded
Oracle’s ORA-19809 guidance lists backing up recovery files with RMAN, reviewing the retention policy or archived-log deletion policy, adding disk space and increasing the configured size, or deleting files from the recovery area using RMAN. Which option is appropriate depends on the recovery design and available capacity. Review retention and recovery requirements before removing recovery files; do not delete files manually as a shortcut. Oracle Database Error Messages: ORA-19809
- Use RMAN backups and policy review when backup and retention rules indicate files can be backed up or become eligible for removal.
- Add storage and adjust the limit when the available storage can support the increased recovery-area capacity. Raising
DB_RECOVERY_FILE_DEST_SIZEalone does not create physical storage. - Use RMAN-managed deletion only after confirming the recovery and retention implications for the files being removed.
If another archive destination failed
For a filesystem or ASM destination, investigate the specific path or disk group reported by Oracle and restore sufficient space or availability. For a remote standby destination, investigate the service and destination state indicated by the error. If a destination is marked MANDATORY, its failure can block archiving even when another destination appears usable; do not disable or alter that requirement without understanding the database’s protection and recovery design. Oracle’s 19c documentation describes these destination types and status attributes, but exact configuration details are release-specific. Oracle Database 19c Reference: V$ARCHIVE_DEST

After correcting the diagnosed issue, verify that the affected destination is valid, enabled, and active as appropriate, and that archiving is proceeding without a new error in the alert log or trace files. Use the destination status and evidence available for the database’s release before declaring the incident resolved. Oracle’s 19c archived-redo guidance also emphasizes checking the alert log and destination status. Oracle Database 19c: Managing Archived Redo Log Files
