Overview of the Framework Resource Groups

This section describes the following framework resource groups:

RAC Framework Resource Group

The RAC framework resource group enables Oracle RAC to run with Sun Cluster. This resource group contains an instance of the following single-instance resource types:

SUNW.rac_framework, which represents the framework that enables Oracle RAC to be managed by using Sun Cluster commands
SPARC: SUNW.rac_udlm, which represents the UNIX Distributed Lock Manager (Oracle UDLM) component of Sun Cluster Support for Oracle RAC

In addition, the RAC framework resource group can contain an instance of a single-instance resource type that represents the volume manager that you are using for Oracle files, if any. This is the legacy configuration that is used in releases before the Sun Cluster 3.2 11/09 release, before the introduction of the SUNW.vucmm_framework resource group to contain multiple-owner volume-manager resources.

Note –

This legacy use of the SUNW.rac_framework resource group to contain volume-manager resources is still supported in this release, but might be deprecated in a future Sun Cluster release.

Solaris Volume Manager for Sun Cluster is represented by the SUNW.rac_svm resource type.
SPARC: VxVM with the cluster feature is represented by the SUNW.rac_cvm resource type.

Note –

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 RAC.

Multiple-Owner Volume-Manager Framework Resource Group

The multiple-owner volume-manager framework resource group enables a multiple-owner shared-storage feature to be used by Oracle RAC.

The multiple-owner volume-manager framework resource group is based on the SUNW.vucmm_framework resource type. This resource group contains the volume manager resources for the multiple-owner volume-manager framework, SUNW.vucmm_svm or SUNW.vucmm_cvm.

When a multiple-owner volume-manager framework resource group is configured, you do not also put a SUNW.rac_svm or SUNW.rac_cvm resource in the SUNW.rac_framework resource group.
