Overview

You can install WAS products on distributed operating systems in two ways, from the discs in the product package or by downloading installation images from the Passport Advantage site, if you are licensed to do so. Distributed operating systems include AIX, HP-UX, Linux, Solaris, and Windows systems.

The installation procedure on distributed platforms uses the InstallShield MultiPlatform (ISMP) program to perform the installation. You can use the installation wizard in graphical interface mode or in silent mode. In silent mode, the installation wizard does not display a graphical interface, but instead, reads your responses from a flat file that you prepare beforehand.

 

WAS ND overview

The ND product lets you create unlimited numbers of the same standalone appservers that you can create with the Express product or the base product. However, the real strength of the ND product is to create and manage a multimachine environment, where you have installed managed appserver nodes on different machines. You can manage all of the appservers as a group, or cell, by using the console of the deployment manager.

Use the Profile Management tool or the manageprofiles command-line tool to create...

A deployment manager controls the configuration for all of the managed nodes in its cell and deploys applications to any managed node in the cell. All of the profiles on a system share the core product binary files that are created during the installation.

The main reason to use managed nodes in a cell versus using the same number of standalone appservers is the centralized administration that the deployment manager provides for the cell. Another advantage is the ability to create clusters in a managed node that the deployment manager can manage with simple workload balancing. You cannot create clusters using the Express product or the base product. The ND product installs appserver nodes that can run in standalone mode. You can also add the nodes to the deployment manager cell to manage them as a group.

Cell profiles are actually two profiles in one. You get a deployment manager profile and a federated appserver profile. You have a choice whether to install Samples and the default application. The default application provides an appserver called server1 and an enterprise application called Default Application. Both the Samples and the default application provide servlets that you can run in a Web browser to test your installation.

Custom profiles are empty nodes that are made operational by adding a deployment manager cell. After adding the node, use the console for the deployment manager to customize the node. For example, create appservers on the node or clusters. A custom node does not include a server1 process as an appserver node does. Nor does it include the default application or any Sample applications. It is truly an empty node that customize.

 

Creating multiple appservers on a single machine

You can create any number of appservers on a single machine. Although each profile is unique, with its own...

...all of the servers share one set of command files and other product binary files. Changes that you make to one server profile do not affect the other servers. Configuration documents are maintained within each profile.

The manageprofiles command and its graphical user interface, the Profile Management tool, create multiple standalone appservers.

You can also create clusters on an appserver node when the node is part of a deployment manager cell. Use the console of the deployment manager to create the clusters and cluster members.

 

Installable components on other discs

Each product package includes an operating system-specific Quick Start disc, unless it is a value-add tool that does not run on the main product operating system. Some operating systems have more than one product disc, such as a disc for an operating system running on a 32-bit hardware platform versus a disc for a 64-bit platform.

WAS disc only contains WAS for either the 32-bit or 64-bit architectures. Also included in the media box is the supplements disc. Use the supplements disc to access installation programs and documentation for...

You can also use the migration tools from this disc or copy the tools to your system.
