Working
Stopped
Partially Running

The state of the cluster is displayed based on the following conditions:

Working: If all the Java EE servers associated with the selected cluster are working.
Stopped: If all the Java EE servers associated with the selected cluster are stopped.
Partially Running: If the selected cluster contains both working and stopped Java EE servers.

Application count

Displays (within parentheses) the total number of applications deployed in the selected cluster.

The Cluster Application tab displays the following Application items in a tabular format:

S. No	Display item	Description
1	Name	Displays a list of application(s) (along with a link button) deployed on the selected cluster. Click this link button to display the general information of the corresponding application in the Application General tab (in the Configuration tab). By default, this column is sorted in ascending order.
2	Description	Displays the description of the application(s) listed in the Name column. If the description is not available for an application, then this column is blank. This column can be sorted.
3	Target	Displays the information of the target (along with a link button) on which the application(s) are enabled. Click this link button to display a list of targets associated with the application in the Application Target tab (in the Configuration tab). The target information display format is "Enabled on `count of targets on which the application is enabled` of `count of targets on which the application is deployed` Target(s)". This column can be sorted.
4	Enabled	Displays check boxes to enable or disable the application(s) listed in the Name column on its associated target(s). If an application is enabled on at least one target, then the corresponding check box is selected. If an application is disabled on any of its targets, then the corresponding check box is cleared. To enable an application, select the corresponding Enabled check box to display the Enable Application dialog box, and then click the OK button. To disable an application, clear the corresponding Enabled check box to display the Disable Application dialog box, and then click the OK button. This column can be sorted. If you enable an application by using a command and a different version of the application is already enabled, then that version is disabled. However, if you enable an application from Administration Console and a different version of the application is already enabled, then that version is not disabled.
5	Action	Displays the Launch button for the application(s) listed in the Name column. To launch an application, click the corresponding Launch button to display the Launch Application dialog box. If you specify the required details in the dialog box and click the OK button, then the application is started in a separate window. If the selected application is not enabled on any of the targets on which it is deployed, then the No Targets dialog box is displayed.

The Cluster Application tab displays the following action items:

Start Cluster button: To start the selected cluster, click the Start Cluster button to display the Start Cluster dialog box, and then click the OK button.
Stop Cluster button: To stop the selected cluster, click the Stop Cluster button to display the Stop Cluster dialog box, and then click the OK button.
Restart Cluster button: To restart the selected cluster, click the Restart Cluster button to display the Restart Cluster dialog box, and then click the OK button.
