A large London based eCommerce company is running Oracle DB System Virtual RAC database on Oracle Cloud Infrastructure (OCI) for their eCommerce application activity. They are launching a new product soon, which is expected to sell in large quantities all over the world.

The application architecture should have minimal cost, no data loss, no performance impacts during the database backup windows and should have minimal downtime.

BTurn off automated backups from the eCommerce database, implement Oracle Data Guard with the Standby database deployed on another availability domain, take backups from the standby database.

CLaunch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure bi-directional replication from the eCommerce Database over to the new VM RAC database using GoldenGate. Take backups from the new VM RAC database.

Show Suggested Answer

Suggested Answer: C

Active Data Guard or GoldenGate are used for disaster recovery when fast recovery times or additional levels of data protection are required. And offload queries and backup to standby system.

Oracle GoldenGate to support a disaster recovery site is to have a working bi-directional data flow, from the primary system to the live-standby system and vice versa.

DataGuard and Automatic Backup

You can enable the Automatic Backup feature on a database with the standby role in a Data Guard association. However, automatic backups for that database will not be created until it assumes the primary role.
