Sun Java Communications Suite 5 Deployment Planning Guide

Instant Messaging High Availability Overview

Configuring Instant Messaging for high availability (HA) by using the Sun Cluster agent provides for monitoring of and recovery from software and hardware failures. The high availability feature is implemented as a failover data service, not a scalable service, and is currently supported only on Solaris.

Note –

You can have multiple Instant Messaging nodes in an HA environment using the same SMTP server.

Before implementing an Instant Messaging HA environment using the Sun Cluster agent, decide which of the following HA deployments best meets your needs.
