Oracle Solaris Cluster HA for Sun Java System Application Server EE (HADB) Overview

This section describes how the Oracle Solaris Cluster HA for Sun Java System Application Server EE (HADB) data service enables the Sun Java System Application Server EE (HADB) software for high availability.

The Oracle Solaris Cluster HA for Sun Java System Application Server EE (HADB) is a data service with appropriate extension properties to configure a database that is mastered on multiple nodes at one time.

See Chapter 1, Planning for Oracle Solaris Cluster Data Services, in Oracle Solaris Cluster Data Services Planning and Administration Guide for general information about data services.

The Sun Java System Application Server EE (HADB) software is packaged with the Sun Java System Application Server Enterprise Edition installation. However, you can run Sun Java System Application Server EE (HADB) and Sun Java System Application Server on separate clusters if appropriate. This document describes how to install and configure the data service that enables you to use Sun Java System Application Server EE (HADB) in a cluster. First, enable Sun Java System Application Server EE (HADB) in your cluster to provide session and Enterprise Java Bean (EJB) persistence. See Sun Java System Application Server Enterprise Edition 8.2 High Availability Administration Guide for information about the Sun Java System Application Server EE (HADB) software.

Implementation of the Oracle Solaris Cluster HA for Sun Java System Application Server EE (HADB) does not assume the existence of applications on which your architecture depends, such as databases and web servers. However, such applications can be configured to be highly available and might run on a different cluster.
