Planning your high availability topology

This topic helps you plan the topology of high availability for your WebSphere® Premises Server.

Requirements

See Prerequisite steps for a high availability system for more information on prerequisites.

Topology

A WebSphere Premises Server high availability topology consists of the following:
  • WebSphere Premises Server deployed in a WebSphere clustered configuration
  • A centralized database
  • A centralized WebSphere MQ server
  • WebSphere Application Server Network Deployment components, which are installed on a machine called the cluster controller.
Note: WebSphere Application Server Network Deployment does not support local operating system security. If you need to enable security in your environment, use LDAP or the custom user registry.

The following points apply to the sample configuration diagram pictured below:
