What is Oracle Site Guard

Oracle Site Guard is a disaster recovery solution that enables administrators to automate complete site switchover and failover.

Oracle Site Guard orchestrates the coordinated failover of Oracle Fusion Middleware, Oracle Fusion Applications, and Oracle Databases. It is also extensible to include other data center software components.

Oracle Site Guard integrates with underlying replication mechanisms that synchronize primary and standby environments and protect mission critical data. It comes with a built-in support for Oracle Data Guard for Oracle database, and Oracle Sun ZFS. Oracle Site Guard can also support other storage replication technologies.

Benefits of Oracle Site Guard

In this section, you learn about the benefits of the Oracle Site Guard.

Oracle Site Guard offers the following benefits:

Minimizes disaster recovery time

Oracle Site Guard operates at the site level, and therefore eliminates the need to tediously perform manual disaster recovery for individual site components like applications, middleware, databases, and so on. The traffic of an entire production site can be redirected to a standby site in a single operation.
Reduces human errors

Disaster recovery involves a complicated orchestration of many precise, interdependent procedures. Oracle Site Guard automates and sequences these procedures to provide fast and seamless disaster recovery operations across sites without any human interaction.
Flexible and customizable

Oracle Site Guard can be adapted for use in any enterprise deployment by customizing and tuning disaster recovery plans. Oracle Site Guard provides mechanisms for customizing operations and handling errors.
Eliminates the need for special skills

Oracle Site Guard operators and administrators do not require any special skills or domain expertise in areas like databases, applications, and storage replication. Oracle Site Guard can continuously monitor disaster recovery readiness and it can do this without disrupting the production site.
