Application Resource Groups

To be highly available, an application must be managed as a resource in an application resource group. You can configure an application resource group for a takeover application or a scalable application. You must also configure application resources and application resource groups on both the primary cluster and the secondary cluster. The data that the application resource accesses must be replicated on the secondary cluster.

The replication for the data volumes that an application resource accesses must be in the same protection group as the applications.

Support for data replication might limit how you configure application resource groups. These requirements and limitations vary with the data replication type you choose. For more information about these requirements, see the Sun Cluster Geographic Edition System Administration Guide.
