The Sun Cluster HA for Oracle E-Business Suite data service provides a mechanism for the orderly startup and shutdown, fault monitoring, and automatic failover of the Oracle E-Business Suite.
Oracle E-Business Suite is a complete set of business applications that enables you to efficiently manage business processes by using a unified open architecture. This architecture is a framework for multi tiered, distributed computing that supports Oracle products. The tiers that compose Oracle E-Business Suite are the database tier, applications tier, and desktop tier. These tiers can be distributed as a logical grouping and can be grouped on one or more nodes.

The distributed nature of Oracle E-Business Suite requires more than one cluster data service if all application and database tiers are to be managed by the cluster.
