Atypical Features of This Data Service

Sun Cluster Support for Oracle Parallel Server/Real Application Clusters is an atypical Sun Cluster high-availability data service. This data service is a set of packages that, when installed, enables Oracle Parallel Server/Real Application Clusters to run on Sun Cluster nodes. This data service also enables Sun Cluster Support for Oracle Parallel Server/Real Application Clusters to be managed by using Sun Clustercommands.

This data service does not provide automatic failover or fault monitoring because the Oracle Parallel Server/Real Application Clusters software already provides this functionality. The Oracle Parallel Server/Real Application Clusters software is not registered with or managed by the Sun Cluster Resource Group Manager (RGM).

You can configure Oracle Parallel Server/Real Application Clusters to use the shared-disk architecture of the Sun Cluster software. In this configuration, a single database is shared among multiple instances of the Oracle Parallel Server/Real Application Clusters software that access the database concurrently. The UNIX Distributed Lock Manager (Oracle UDLM) controls access to shared resources between cluster nodes.
