Overview

Language:

The Oracle Essbase Server data service provides orderly startup, shutdown, fault monitoring, and automatic failover of the Essbase Server. Use the information in this section to understand how to make the Essbase Server highly available.

The HA for Oracle Essbase Server provides fault monitoring and automatic failover for the Enterprise Server to eliminate single points of failure in a Oracle Essbase Server system. Figure 1, Table 1, Oracle Essbase Server System Components and Their Data Services lists the data service that protects each of the Oracle Essbase Server components in an Oracle Solaris Cluster configuration.

Note - You can install and configure this data service to run in either the global zone or a zone cluster. For updated information about supported configurations of this data service, see the Oracle Solaris Cluster 4 Compatibility Guide.

Table 1 Oracle Essbase Server System Components and Their Data Services

Oracle Essbase Server System Component	Data Service
Database server	The data service for the database that you are using: For the Oracle database, the data service is explained in the Oracle Solaris Cluster Data Service for Oracle Database Guide. For the Oracle RAC database, the data service is explained in the Oracle Solaris Cluster Data Service for Oracle Real Application Clusters Guide. For the Oracle External Proxy, the data service is explained in the Oracle Solaris Cluster Data Service for Oracle External Proxy Guide.
Application server	The data service is HA for Oracle Essbase. The resource type is `ORCL.essbase`. The data service is explained in this guide.
Web server	The data service is explained in the Oracle Solaris Cluster Data Service for Oracle WebLogic Server Guide.

High availability is provided for the Oracle Essbase Server component of the Oracle Essbase system.

The Oracle Essbase Server component can be configured as a failover data service.

For conceptual information about failover services, see the Oracle Solaris Cluster 4.3 Concepts Guide.

HA for Oracle Essbase requires that a functioning cluster with the initial cluster framework is already installed. See the Oracle Solaris Cluster 4.3 Software Installation Guide for details on initial installation of clusters and data service software. You register the HA for Oracle Essbase after you successfully install the basic components of Oracle Solaris Cluster and Oracle Essbase Server software.

For information about which version of Oracle Essbase Server software is compatible, see the Oracle Solaris Cluster Compatibility Guide available at the Oracle Solaris Cluster Technical Resources page.
