By default, the provisioning system's command-line interface is located in the following directory: /opt/SUNWn1sps/N1_Service_Provisioning_system_5.2/cli/bin/cr_cli
WebSphere 3.0 plug-in objects are located in the /com/sun/was/5.1 folder.
You can interact with plug-in components and plans much like any other custom component or plan. However, if you want to make changes to the components or plans, you must save the component or plan to a new folder and make your changes there. For more information about using the provisioning system's command-line interface, see Chapter 1, Using the Command-Line Interface, in Sun N1 Service Provisioning System 5.2 Command-Line Interface Reference Manual
