Chapter 1

Preparing for SEM-HA Installation

This chapter describes the installation requirements and other information you need before installing High Availability for Solstice EM (SEM-HA). It also contains a checklist to use if you have a problem installing the software. The checklist outlines the information you need to provide if you call customer support.

The following topics are covered in this chapter:

1.1 Overview

SEM-HA enables Solstice EM to be highly available when supported by a cluster of servers (Sun Cluster Servers). A highly available system contains no single point of failure.

Sun Cluster provides high availability support for data service applications, such as Solstice EM. In a HA environment (such as Solstice EM) the software application runs on the primary server. If the primary server fails, a backup server in the cluster takes over designated applications from the primary server, and then applications are able to resume services with minimal disruption.

For more information on Sun Cluster high availability feature, refer to the Sun Cluster 3.0 Concepts Guide.

1.2 System Requirements

Your system must meet the following hardware and software requirements before SEM-HA can be installed.

1.2.1 Hardware Requirements

SEM-HA runs on any hardware supported by the Sun Cluster 3.0 configuration and Solstice EM 4.1.
