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 contains an instance of a single-instance resource type that represents the volume manager that you are using for Oracle files, if any.
Solaris Volume Manager for Sun Cluster is represented by the SUNW.rac_svm resource type.
VxVM with the cluster feature is represented by the SUNW.rac_cvm 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 RAC.
