Oracle Active Data Guard

Make Productive Use of Your Standby Database
Oracle Active Data Guard—an option for Oracle Database 11g Enterprise Edition—enhances Quality of Service by offloading resource-intensive activities from a production database to one or more synchronized standby databases. 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 received from the production database. Oracle Active Data Guard also enables the use of 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.

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—Reporting replica is up-to-date and online at all times - not possible with traditional storage mirroring technology
  • Reduce cost—An Active Data Guard physical standby database can also provide disaster recovery and/or serve as a test database - no additional storage or servers required
