Replicated Database

Replicated database architecture is a potential solution to maintain database system high availability for your organization’s database systems. Version 8.x of Oracle called these replicated databases a standby database. With Oracle 9.x, Oracle simplifies the replication management process with a tool named Data Guard.

Oracle Data Guard ensures high availability, data protection, and disaster recovery for enterprise data. Data Guard provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions.

Data Guard maintains these standby databases as transactionally consistent copies of the production database. Then, if the production database becomes unavailable because of a planned or an unplanned outage, Data Guard can switch any standby database to the production role, thus minimizing the downtime associated with the outage. Data Guard can be used with traditional backup, restoration, and cluster techniques to provide a high level of data protection and data availability.

Inplexus can assist your organization with architecting, deploying and training your staff with Oracle standby databases and Data Guard. If your primary database fails, you can switch to the standby database with little interruption in business.
