  Oracle Database Tips by Donald Burleson

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

Using Sun Cluster 3.x Environment

In order for RAC to use the shared disk architecture of Sun Cluster, to share the single database among multiple instances of RAC, to access the database concurrently, and to control conflicting access to the database, the Oracle UNIX distributed lock manager (udlm) is needed. There is another component called the Oracle Node Monitor, referred to as ORCLUdlm package, which is usually supplied along with the Oracle software. You need to install both of these packages.

Using Veritas DBE/Advanced Cluster

VERITAS Storage Foundation for Oracle RAC provides an integrated solution that includes the VERITAS clustering, file system, and volume management technologies. The solution delivers cluster and file system supporting Oracle RAC on the Solaris and HP-UX operating systems. Storage Foundation includes the Database Edition/Advances Cluster for Oracle RAC.
