Sun Cluster Data Service for WebLogic Server Guide for Solaris OS

Sun Cluster HA for BEA WebLogic Server Overview

Use the information in this section to understand how to make the BEA WebLogic Server application highly available.

BEA WebLogic Server running on Sun Cluster systems delivers a highly available platform for developing and deploying mission-critical e-commerce applications across distributed, heterogeneous application environments.

The Sun Cluster HA for BEA WebLogic Server provides fault monitoring and high availability for the BEA WebLogic Server application. High availability is provided for the WebLogic Administration Server and WebLogic Managed Servers. Because Sun Cluster HA for BEA WebLogic Server only supports the non-clustered BEA WebLogic Servers, the client sessions could be lost during the failover or restart.

Note –

Sun Cluster HA for BEA WebLogic Server provides high availability to stand-alone WebLogic Server instances (instances not using WebLogic Server clustering).

For conceptual information on failover services, see the Sun Cluster Concepts Guide for Solaris OS.
