Installing WebSphere Application Server products

To create a complete environment for installation, install any prerequisites and prepare the operating platform for installation. During installation, you can optionally migrate the configuration from a previous version of the product. After installation, you can run the installation verification test and bring up your Application Server.

 

Overview

Perform the following tasks to create a running version of the product on your machine.

1. Plan to install an e-business network
2. Install the product

This task helps you prepare your machine for installation and explains the different types of installation available to you. It includes information on:

1. Using the Launchpad
2. Deciding whether to migrate applications and the configuration from a previous version
3. Deciding whether to coexist with a previous version
4. Using the silent installation method

This task describes using the installation wizard. Through the installation wizard, you migrate applications and configurations from a previous version of WebSphere Application Server, coexist with the previous version, choose a full installation type or a custom installation type, and perform some initial configuration.

Migrate Enterprise, V5.0.x or Enterprise Edition, V4.x to WebSphere Business Integration Server Foundation, Version 5.1.

Migrating to base or Network Deployment issues warnings that describe the parts of your configuration that are disabled. The migration tools record these warnings in a log file. If you have already migrated and disabled the extensions in your applications, you can enable the extensions again by installing Integration Server and selecting the migration option.

There is no Enterprise Edition in Version 3.5.x or V4.0.x. If you are migrating from a V3.5.x product or a V4.0.x product, migrate when you install the V5.1 base product or the V5.1 Network Deployment product. After migrating, install the WebSphere Business Integration Server Foundation product.

The Network Deployment node must be at the highest product level within its cell. The following table shows if a particular base product configuration is allowed within a Network Deployment node.

Mixed version cells in V5.1

Application Server node	Network Deployment
	V5.0.0	V5.0.1	V5.0.2	V5.1
V5.0.0	Yes	Yes	Yes*	Yes*
V5.0.1	No	Yes	Yes*	Yes*
V5.0.2	No	No	Yes	Yes
V5.1.x	No	No	No	Yes

* The base node cannot have the embedded messaging feature installed.

Verify the installation.

1. Use the First Steps tool to run the Installation Verification Test, as described in Using the installation verification test.

   The First Steps tool starts automatically at the end of the installation.

2. Identify and correct any problems using the troubleshooting procedure, as described in Troubleshooting the installation.

Examine the results of migration, or prepare to perform a manual migration, as described in Migrating and coexisting.

This task describes exactly what is migrated during the automatic migration. It also describes how to perform a manual migration using the migration tools.

Prepare to migrate from an unsupported operating system, as described in Migrating from an operating system that is no longer supported.

This task describes a basic procedure to follow when migrating from one operating system to another.

Configure WebSphere Application Server after migration, as described in Configuring WebSphere Application Server after migration.

This task explains how to check migrated application and configuration information, to understand and configure exactly what you migrated.

• If you migrate from V3.5.x, examine the applications that you are moving. Make any necessary changes to the applications that are converted to Java 2 Platform, Enterprise Edition (J2EE) platform applications. The migration tools create the initial J2EE enterprise applications, based on V3.5.x configurations.

• If you migrate from V4.x, you have little to review. J2EE 1.2 enterprise archive (EAR) files in V4 work in V5 of WebSphere Application Server, which also supports the J2EE 1.3 specification.

Set up a multinode environment, as described in Establishing multimachine environments.

This task describes how to set up multiple nodes into a group or cell of Application Servers, with centralized configuration under the control of the deployment manager node and its distributed node agents.

Set up V3.5.x and V5 coexistence, as described in Setting up V3.5.x and V5 coexistence.

This task describes running WebSphere Application Server V3.5.5 and later editions with V5.x, on the same machine.

Set up V4.0.x and V5 coexistence, as described in Setting up V4.0.x and V5.x coexistence.

This task describes running WebSphere Application Server V4.0.2 and later editions with V5.x, on the same machine.

Set up V5.x coexistence, as described in Setting up V5 coexistence.

This task describes running multiple WebSphere Application Server product installations on the same machine.

Automatically restart WebSphere Application Server processes, as described in Automatically restarting server processes.

This task describes how to set up WebSphere Application Server processes for the operating system to monitor and restart.

Create multiple V5 instances on one machine, as described in Creating multiple V5 configuration instances.

This task describes creating multiple configuration instances from one installation. It also describes creating multiple servers in a coexistence or multiple instance environment, and changing port settings for HTTP transport to avoid conflicts.

Apply an interim fix, a cumulative fix, or a fix pack to an existing installation, as described in Installing interim fixes, cumulative fixes, and fix packs.

This task helps you apply maintenance to WebSphere Application Server products after you download the maintenance from the Support page.

Remove an interim fix, a cumulative fix, or a fix pack from an existing installation, as described in Uninstalling interim fixes, cumulative fixes, and fix packs.

This task helps you remove applied maintenance from WebSphere Application Server products.

Tune for performance.
