Oracle Database Tips by Donald Burleson

Oracle10g Grid Computing with RAC
Chapter 6 - Install, Configure and Database Creation

Using Veritas DBE/Advanced Cluster

Veritas Database Edition/Advanced Cluster (DBE/AC) provides a complete I/O and communications stack to install, configure, and support Oracle RAC on a Solaris-based Sun cluster. It also provides monitoring and management of instance startup and shutdown. DBE/AC provides a comprehensive cluster framework and software facility.

With the availability of Veritas DBE/AC for RAC implementation on a Sun Cluster and HP-UX cluster, we are no longer limited to clusterware provided by Sun and HP. The Veritas Cluster Server, supporting Oracle RAC, is pretty much an extended and enhanced version of the VCS used for database failover clusters. Administrators already familiar with the VCS for HA cluster find it easier to understand and implement. Veritas DBE/AC is a certified cluster framework that is built in with Cluster File System and it is ODM compliant.

We will cover and examine the following topics in this section:

• Communication stacks which deal with inter-node communication
   

• Shared Storage Configuration, ODM, CFS, and Cluster Volume Manager
   

• VCS architecture framework
   

• IO Fencing
   

• Installation of Veritas software

Communication Stack

There are two components in the Veritas communication stack.
