Mission-critical databases need disaster recovery as quickly as the business demands. Oracle Data Guard has long helped organizations protect mission-critical workloads and support business continuity.
Oracle Data Guard Automatic Failover for Oracle Exadata Database Service on Exascale Infrastructure further strengthens Oracle’s commitment to business continuity. It provides customers with an expanded operational choice, automating Oracle Data Guard Observer deployment, health monitoring, and failover orchestration to simplify disaster recovery operations and reduce recovery time.
Automation for Oracle Data Guard Automatic Failover
Many organizations use an Oracle Data Guard standby database to protect critical workloads from database or infrastructure failures., In case of an outage of the primary database, however, operations teams currently need to recognize the event, assess the situation, and then initiate a database role transition by making the standby database the new primary database. These steps require coordination during an outage and can add to recovery time.
Oracle Data Guard Automatic Failover automates Observer deployment, database monitoring, and failover orchestration. Connection details for both database roles are provided for administrators to use with their applications. When configured failover conditions are met, Oracle Data Guard Observer promotes the standby database to the primary role automatically, enabling application workloads to continue to operate on the new primary database, eliminating the need for manual intervention. This helps operations teams focus on restoring normal business service rather than coordinating the mechanics of a database failover.
Oracle Data Guard Automatic Failover helps protect data integrity, maintain the availability of critical workloads, and reduce overall recovery time. Customers retain full control over their primary and standby databases, while Oracle automates the underlying health monitoring and failover orchestration through capabilities such as:
- Automatic failover for an existing Data Guard configuration with a guided console workflow.
- Creation of a new standby with automatic failover enabled by default.
- Management of failover targets with multiple standbys as application and resilience requirements evolve.
- Download of connection details for the primary and standby databases to support application connectivity after a database role transition.
Key takeaways
Data Guard Automatic Failover on Oracle Exadata Database Service on Exascale Infrastructure helps organizations strengthen their availability posture by providing:
