Oracle Active Data Guard enables read-only access to a physical standby database for queries, reporting, webbased
access, etc., while continuously applying changes received from a production database. Oracle Active Data
Guard now includes Global Data Services, Far Sync, Fast Sync, Real-time cascading, and DML on Global
Temporary Tables. No changes to the production database are lost during testing. Oracle Active Data Guard also
enables the use of fast incremental backups when offloading backups to a standby database.
