THE solution for Oracle data protection, data availability, and disaster recovery.

Oracle Data Guard provides the management, monitoring, and automation software to create and maintain one or more standby databases to protect Oracle data from failures, disasters, human error, and data corruptions while providing high availability for mission critical applications. Data Guard is included with Oracle Database Enterprise Edition.

Oracle Active Data Guard is an option for Oracle Database Enterprise Edition. Its advanced capabilities are a superset of Data Guard functionality, including:

  • Real-Time Query to offload read-only workloads to an up-to-date standby database. This adds capacity, improves response time, and increases return on investment. It also provides continuous validation that the standby database is production-ready.
  • Automatic Block Repair to transparently repair physical corruptions wherever they occur, at either the primary or standby database.
  • Far Sync to enable zero data loss protection and off-host network compression, even when primary and standby are hundreds or thousands of miles apart.
  • RMAN Block Change Tracking to offload fast incremental backups to an Active Data Guard Standby with 20x the performance of traditional incremental backups.
  • Active Data Guard Rolling Upgrade to make it simple to reduce planned downtime and minimize the risk of introducing change to production systems.
  • Global Database Services to provide intelligent load balancing and automated service management across replicated databases. See Global Data Services for more details.
  • Application Continuity to make outages transparent to users by reliably handling in-flight transactions. See Application Continuity for more details.

Data Guard and Active Data Guard have been implemented by many users worldwide. See the Reference Catalog by Industry Vertical or click on the Case Study link below.
