Requirements and Sequence Issues

Application Server requires a local copy of Message Queue. Application Server and HADB must be on the same host so you can use the integrated management tools provided by Application Server. The Load Balancing Plugin subcomponent of Application Server requires a web server. This example uses the Java ES Web Server as the container.

The general tasks include:

1. Installing the Java ES components

2. Starting the servers

3. Configuring HADB

4. Configuring load balancing

You can use the following guidelines to install all components on a node or zone. On subsequent nodes, install the components required by your deployment. A minimum of two installation sessions are required.

To Develop a Sequence for Web and Application Services

The following high-level tasks are required:

Steps

1. Verifying that the hardware is connected correctly for your cluster

2. Running the Java ES installer

3. At component selection, choosing Application Server and High Availability Session Store

   Message Queue and all the subcomponents of Application Server except the Application Server Node Agent and Load Balancing Plugin are automatically selected.

4. Expanding the Application Server component and selecting Load Balancing Plugin.

   Note –

   You must install Web Server and Load Balancing Plug-in using the same access permissions.

5. Resolving incompatibilities

   The installer verifies software on your host and provides guidance if incompatibilities are identified.

6. Selecting the Configure Now option

   Message Queue requires no configuration.

   The configuration pages are displayed for components that can be configured during installation. Gather your configuration information from the table in HADB Configuration Information in Sun Java Enterprise System 2005Q4 Installation Reference.

7. Running the installation

8. Viewing the Installation Summary and Log

9. Starting the components:

   • Starting and Stopping Application Server (Message Queue automatically starts.)

   • Starting and Stopping Web Server

10. Completing HADB postinstallation configuration

    Refer to Configuring HADB After a Configure Later Installation.

11. Completing load balancing configuration

    Refer to the Chapter 4, Configuring Load Balancing and Failover, in Sun Java System Application Server Enterprise Edition 8.1 2005Q2 High Availability Administration Guide.
