How to Create an Application Server Instance

When you create a standalone application server, you automatically create one application server instance, server1. If you must create additional application server instances, use this procedure.

You can use this procedure to create an application server instance or you can use this procedure to capture an existing application server instance within the provisioning system.

This task is performed as root.

Before You Begin

Before you create an application server instance, you must create a standalone application server. For more information, see How to Install a Standalone WebSphere Application Server.

Steps

1. In the Common Tasks section in the browser interface, click WebSphere 5.1.

2. Click the Application Server Instances: Install link.

   The plan's Details page displays.

3. Click Run.

   The plan's Run page displays.

4. In the Plan Parameters area, select the variable settings for the AppInstance component that you plan to deploy.

   Each new application server instance needs a unique name. You must create a new variable set to indicate the name for each new application server instance.

   • If the variable settings have been established for this component, select the appropriate settings from the menu.

   • If the settings are not available from the menu, click Select From List.

     The Select Variable Settings From List window displays.

     • To create a new set of variable settings, select Create Set.

       The following list provides commonly-updated variables for the AppInstance component. The AppInstance variable settings rely primarily on the standalone application server's variable setting values. You can keep the default values for most variables.

       variable set name

       Required. A name for the new variable set you create.

       name

       Required. The name of the application server instance.

     • To use variable components from another component, click Import Set.

       For more information about importing variable sets, see How to Run a Plan in N1 Grid Service Provisioning System 5.0 Operation and Provisioning Guide.

5. Select the target host.

   Install the application server instance on the virtual host of a standalone application server.

6. Deselect the Target Host Set checkbox.

7. If you are capturing an existing standalone application server within the provisioning system, select the markOnly Install option.

   This option enables you to create a component that represents an existing WebSphere 5.1 object and then manage the object through the provisioning system.

8. Click Run Plan (Includes Preflight).

9. View the Hosts page to verify that the new application server instance virtual host was created.
