Select servers - Map modules to servers settings

Use this panel to specify deployment targets where you want to install the modules contained in your application. Modules can be installed on the same deployment target or dispersed among several deployment targets. Each module must be mapped to a target server. A deployment target can be an application server, cluster of application servers or Web server.

To view this administrative console panel, click Applications > Enterprise Applications > application_name > Map modules to servers. This panel is the same as the Map modules to servers panel on the application installation and update wizards.

On this panel, each Module must map to one or more desired targets, identified under Server . To change a mapping:

1. In the list of mappings, select the Select check box beside each module that you want mapped to the same target(s).

2. From the Clusters and Servers drop-down list, select one or more targets. Select only appropriate deployment targets for a module. Modules that use WebSphere Application Server Version 6.x features cannot be installed onto a Version 5.x target server.

   Use the Ctrl key to select multiple targets. For example, to have a Web server serve your application, press the Ctrl key and then select an application server or cluster and the Web server together. The plug-in configuration file plugin-cfg.xml for that Web server will be generated based on the applications which are routed through it.

3. Click Apply .

Clusters and Servers

Lists the names of available target servers and clusters. This list is the same for every application that is installed in the cell. From this list, select only appropriate deployment targets for a module. You can install an application, enterprise bean (EJB) module or Web module developed for a Version 5.x product on a 5.x or 6.x deployment target, provided the module--

• Does not support Java 2 Platform, Enterprise Edition (J2EE) 1.4;

• Does not call any 6.x runtime application programming interfaces (APIs); and

• Does not use any 6.x product features.

If the module supports J2EE 1.4, calls a 6.x API or uses a 6.x feature, then install the module on a 6.x deployment target.

Module

The name of a module in the installed (or deployed) application that you selected on the Enterprise Applications page.

URI

The location of the module archive contents on a file system. The location is relative to the application URL. The URI must match the URI of a ModuleRef URI in the deployment descriptor of the deployed application (.ear file).

Server

The name of each server or cluster to which the module currently is mapped--that is, the deployment targets.

To change the deployment targets for a module, select one or more targets from the Clusters and Servers drop-down list and click Apply. The new mapping replaces the previous mapping.
