Overview of the RAC Framework Resource Group

The Real Application Clusters (RAC) framework resource group enables Oracle Parallel Server/Real Application Clusters to be managed by using Sun Cluster commands. This resource group contains an instance of the following single-instance resource types:

• SUNW.rac_framework, which represents the framework that enables Oracle Parallel Server/Real Application Clusters to be managed by using Sun Cluster commands

• SUNW.rac_udlm, which represents the UNIX Distributed Lock Manager (Oracle UDLM) component of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters

In addition, the RAC framework resource group contains an instance of a single-instance resource type that represents the storage management scheme that you are using.

• VxVM with the cluster feature is represented by the SUNW.rac_cvm resource type.

• Hardware RAID support is represented by the SUNW.rac_hwraid resource type.

• The cluster file system is not represented by a resource type.

The resource types that are defined for the RAC framework resource group do not enable the Resource Group Manager (RGM) to manage instances of Oracle Parallel Server/Real Application Clusters.
