Starting a component in an Application

bwdmin Command Line

To start a component in an application, run the startcomponent command or click the Stop icon in the Admin UI.

When an application is started, the default action starts all the components of the application on each AppNode, defined in the AppSpace. However, a component can be stopped using the stopcomponent command. The startcomponent command can then be used with the -appnode option to start a component of an application on a specific AppNode.

Procedure

  1. Start the AppSpace.
  2. Execute the startcomponent command for the component of an application. For example: 
    BW_HOME\bin>bwadmin startcomponent -d MyDomain -a MyAppSpace -n MyAppNode MycomponentName tibco.bw.sample.MyApp.application 1.0
    Note: To enable auto start of a component with process starter activity, use enablecomponentautostart command. For example: 
    BW_HOME\bin>bwadmin enablecomponentautostart -d MyDomain -a MyAppSpace -n MyAppNode ComponentReceiver jmsSenderReceiver.application 1.0
    This functionality is applicable at AppSpace level and not at AppNode level.

Admin UI

When an application is started, the default action starts all the components of the application on each AppNode defined in the AppSpace. Click the Components tab to view the components in the application. Click the Start icon to start all the components in the Appnodes. If all the components are running, the Status changes to started. The status bar displays the number of components running on the AppNodes. On hovering over the status bar, you can see the number of running components. To start a component on a specific AppNode, click the icon on the left to view the list of AppNodes the component is running on. Click the Start icon against the component you want to start.
Note: The icon to collapse the list of AppNodes the component is running on, is enabled only after the application has started.
Note: Starting the top level Start icon starts all the components with auto start toggle button on for all the AppNodes.

To enable auto start of a component:

Procedure

  1. Select Application Level 2 page and select the Component tab.
  2. Use the toggle button in the Auto Start column for each component process to decide whether to enable auto start of a component process or not during execution.

  3. Restart an application to take effect the changes.
