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:

  • On a server or dispatcher level - the property change will be relevant only for the current specific server/dispatcher node. Choose Cluster.
  • On a global level - the property change will be applied to all dispatchers or servers in the cluster. Choose Global Configuration.

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

Tip  
Note EXAMPLE:  You have a cluster consisting of one dispatcher and three server nodes. If you want to modify the value of a log configuration property in order the change to take effect on all the three server nodes, make the change on a global level.

If you want to apply a different property value on server 1, for example, you can do this within the Cluster tab. As a result, servers 2 and 3 will operate with the value set on a global level, and server 1 - with the new value.

Procedure
Caution

Your changes take effect only after restart of J2EE Engine.

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

Accessing Global / Specific Configurations

Global Server / Dispatcher Configuration

  1. Choose the Global Configuration tab.
  2. To configure all server/dispatcher processes in the cluster, choose the Server / Dispatcher tab, respectively.
  3. Choose Kernel, Interfaces, Libraries or Services according to the cluster element whose property you want to configure.

Specific Server / Dispatcher Configuration

  1. Choose the Cluster tab.
  2. To view the J2EE Engine components, expand cluster's root elements in the left pane.
  3. Select the element whose property you want to configure - either Server or Dispatcher element.

 

Configuring Managers

  1. Expand the Kernel node and choose the manager you need.
  2. From the Properties list, select the relevant property and modify it. To see the new value, choose Update.
  3. Choose Save.
  4. In order the change to take effect, you are required to restart J2EE Engine.

Configuring Services

  1. Expand the Services node and choose the service you need.
  2. From the Properties list, select the relevant property and modify it. To see the new value, choose Update.
  3. Choose Save.
  4. In order the change to take effect, you are required to restart J2EE Engine.
  5. You can see more details about the Java services within the Additional Info tab.

Accessing Libraries and Interfaces

Libraries and interfaces are available on a Cluster level only.

You can view details but cannot modify them.
