Oracle Active Data Guard enhances the performance of production databases by offloading resource-consuming operations to one or more standby databases. This protects interactive users and critical business tasks from the impact of long-running operations.
Active Data Guard enables a physical standby database to be used for real-time reporting with minimal latency. Compared to traditional replication methods, it is simple to use and has very good performance.
Oracle Active Data Guard enables read-only access to a physical standby database for queries, sorting, reporting, web-based access, etc., while continuously applying changes or archived logs received from the production database.
Active Data Guard also enables fast incremental backups when offloading backups to a standby database, and can provide additional benefits of high availability and disaster protection against planned or unplanned outages at the production site.
Features
- Physical Standby with Real-Time Query
- Fast Incremental Backup on Physical Standby
Benefits
- Increase performance– Offload unpredictable workloads to an up-to-date replica of the production database
- Simplify operations– Eliminate management complexity that accompanies traditional replication solutions
- Eliminate compromise– The reporting replica is up to date and online at all times, which is not possible with traditional storage mirroring technology
- Reduce cost– An Oracle Active Data Guard physical standby database can also provide disaster recovery and/or serve as a test database – no additional storage or servers required
- Enables a standby database for use in real-time for reporting
- Offloads backup operations
- Insulates critical operations from unexpected system impacts
- Provides high availability and disaster protection
