Accessing Components 

Use

You can use the Visual Administrator tool to access and manage services, interfaces, libraries, and managers. You can modify the properties of the services and managers in two ways:

●      At server or dispatcher element level – the changes will be relevant only for the specific element that you have modified.

●      At global level – the changes that you make will be applied to all dispatcher or server elements in the cluster.

The global configuration is overwritten by the local configuration of the server or dispatcher element.

For example, you have a cluster consisting of one dispatcher and three server elements. If you want to modify the value of a certain property for all three server elements, you have to make your changes at a global level (in the Global Configuration tab).

If you want to have a different value for that property on server one, for example, you have to make your changes only for server one in the Cluster tab. Then, server elements two and three will operate with the value set at global level, and server one will operate with the value set explicitly at server level.

Procedures

When you change the value of a property that requires the J2EE Engine to be restarted and then you save your changes, the Visual Administrator displays the old value that is in use by the J2EE Engine. If you continue configuring the J2EE Engine without restarting it first, any subsequent change and save operation deletes your previous changes and preserves only the current values that are displayed in the Visual Administrator. Your changes will become effective only after you restart the J2EE Engine.

Accessing the Global Server or Dispatcher Configuration

...

       1.      Choose the Global Configuration tab.

       2.      If you want to configure all server processes in the cluster, choose the Server tab.

       3.      If you want to configure all dispatcher elements in the cluster, choose the Dispatcher tab.

       4.      To access the managers, expand Kernel.

       5.      To access the services, expand Services.

       6.      Manage the chosen component.

Your changes will be valid for all dispatcher or server elements in the cluster.

Accessing a Specific Server or Dispatcher Configuration

...

       1.      Choose the Cluster tab.

       2.      To view the J2EE Engine components, expand the cluster’s root element in the left pane.

       3.      Select the element you want to configure – either Server or Dispatcher element.
