Configuration Roadmap for High Availability of GlassFish Server

The following procedure lists the major tasks for configuring GlassFish Server for high availability. The procedure also provides cross-references to detailed instructions for performing each task.

To Configure GlassFish Server for High Availability

1. Determine your requirements and goals for performance and QoS.

   For more information, see the following documentation:

   • Establishing Performance Goals

   • Planning the Network Configuration

   • Planning for Availability

2. Size your system.

   For more information, see Design Decisions.

3. Install GlassFish Server and related subcomponents such as a web server.

   For more information, see the following documentation:

   • Oracle GlassFish Server 3.1 Installation Guide

   • Installation guides for related subcomponents, for example, Oracle iPlanet Web Server 7.0.9 Installation and Migration Guide

4. If you plan to administer your clusters centrally, set up secure shell (SSH) for centralized administration.

   For more information, see Chapter 2, Setting Up SSH for Centralized Administration, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide.

5. Configure domains, nodes, clusters, GlassFish Server instances, and virtual servers as required.

   For more information, see the following documentation:

   • Chapter 3, Administering Domains, in Oracle GlassFish Server 3.1 Administration Guide

   • Chapter 3, Administering GlassFish Server Nodes, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

   • Chapter 4, Administering GlassFish Server Clusters, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

   • Chapter 5, Administering GlassFish Server Instances, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

   • Administering Virtual Servers in Oracle GlassFish Server 3.1 Administration Guide

6. Configure your load balancer.
   • If you are using a web server for load balancing, configure the web server and Load Balancer Plugin as follows:
     1. Configure the web server software for load balancing.

        For more information, see the following documentation:

        • Configuring Oracle iPlanet Web Server in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

        • Configuring Apache HTTP Server in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

        • Configuring Microsoft IIS in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

        • Configuring Oracle HTTP Server in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

     2. Install the Load Balancer Plugin.

        For more information, see Installing the Loadbalancer Plug-In in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide.

     3. Configure the Load Balancer Plugin.

        For more information, see Chapter 8, Configuring HTTP Load Balancing, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide.

   • If you are using the Apache Tomcat Connector mod_jk for load balancing, configure mod_jk.

     For more information, see Administering mod_jk in Oracle GlassFish Server 3.1 Administration Guide.

7. Configure the web container and EJB container for replicated session persistence.

   For more information, see Chapter 10, Configuring High Availability Session Persistence and Failover, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide.

8. If you are using messaging extensively, configure Java Message Service (JMS) clusters for failover .

   For more information, see the following documentation:

   • Planning Message Queue Broker Deployment

   • Chapter 11, Configuring Java Message Service High Availability, in Oracle GlassFish Server 3.1-3.1.1 High Availability Administration Guide

   • Oracle GlassFish Server Message Queue 4.5 Administration Guide

9. Deploy applications and configure them for high availability and session failover.

   For more information, see Oracle GlassFish Server 3.1 Application Deployment Guide.
