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 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.

Table 1 Oracle E-Business Suite Architecture

Desktop Tier	Application Tier	Database Tier
	Web Server
	Forms Server
Web Browser	Concurrent Server	Database Server
	Reports Server
	Admin Server
	Discoverer Server

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.

The following tables list the Oracle E-Business Suite components and the corresponding cluster data service that provides high availability to that component.

Table 2 Protection of Components

Component	Protected by
Database Server	Sun Cluster HA for Oracle (Database and Listener)
Web Server	Sun Cluster HA for Apache
Forms Server	Sun Cluster HA for Oracle E-Business Suite
Concurrent Manager Server	Sun Cluster HA for Oracle E-Business Suite
Concurrent Manager Listener	Sun Cluster HA for Oracle (Listener)
Reports Server	Sun Cluster HA for Oracle E-Business Suite

The Admin Server and Discoverer Server are not normally run within Sun Cluster and therefore are not protected by Sun Cluster HA for Oracle E-Business Suite.
