Installing your application serving environment > Distributed operating systems

You can install WebSphere Application Server 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.

WebSphere Application Server Network Deployment overview

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

Use the Profile creation wizard or the profile creation command-line tool, wasprofile, to create deployment manager profiles, application server profiles, and custom profiles.

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 application servers 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 Network Deployment product installs application server nodes that can run in standalone mode. You can also add the nodes to the deployment manager cell to manage them as a group.

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

Creating multiple application servers on a single machine

You can create any number of application servers on a single machine. Although each profile is unique, with its own configuration, applications, data, logs, and administrative console, 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 wasprofile command and its graphical user interface, the Profile creation wizard, create multiple standalone application servers.

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

Other installable components

You can install IBM HTTP Server, the Web server plug-ins for WebSphere Application Server, and the Application Clients for WebSphere Application Server.

Each installation procedure is described in this documentation or in the IBM HTTP Server documentation.

Each product package includes discs for all of the distributed systems. 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.
