VERITAS Cluster Server
ODM Clustering Extensions
All ODM features can operate in a cluster environment. Nodes communicate with each
other before performing any operation that could potentially affect another node. For
example, before creating a new data file with a specific name, ODM checks with other
nodes to see if the file name is already in use.

Storage Foundation for Oracle RAC Service Groups
Storage Foundation for Oracle RAC uses parallel service groups to support RAC. A single
CVM group exists per server. This group has the CVM resource and the necessary
resources to support CFS. Users can modify this group to contain all common components
needed by Oracle to support RAC. These components include a shared ORACLE_HOME
directory and the Oracle Net Services process (LISTENER).
