What's New in the Sun N1 Advanced Architecture for SAP Solutions 5.2 Update 2 Release

Chapter 4 J2EE Application Server Support in N1 Advanced Architecture 5.2 Update 2 Release

This chapter describes how to model a J2EE application server in your SAP environment with the SAP plug-in.

Creating J2EE Applications Servers With the SAP Plug-In

The new version of the SAP plug-in supports the creation of J2EE application server components. The new component variable isJ2EE allows you to indicate that an application server component refers to a J2EE application server.

Note –

You cannot move J2EE application servers between systems in the N1 AA web console. If you try to move a resource group that includes a J2EE application server resource, the move will fail.

How To Create a J2EE Application Server in the N1 Service Provisioning System

This task creates an SAP Application Server entry in the N1 SPS database.

Note –

This task is a markOnly task. The J2EE application server must be running in your SAP environment before you perform this task.

In the Common Tasks section of the N1 SPS browser interface, click SAP.

In the Application Server section of the SAP Tasks page, click Create.

Click Run.

In the Plan Parameters table, select the variable settings for the AppServer component.
- If the variable settings have been created for this component, select the appropriate settings from the drop-down menu.
- If the variable settings are not available from the drop-down menu, follow these steps.
  1. Click Select From List. The Select Variable Settings From List window displays.
    - To create a new variable settings set, click Create Set and type a Set Name.
      
      The following list provides commonly updated variables for the AppServer component. To create a value for the component variable, click the check box in the component variable's row.
