Interface DeploymentServiceMBean

public interface DeploymentServiceMBean

The deployment service MBean allows administrative tools to manage service assembly deployments. The tasks supported are:

• Deploying a service assembly.
• Undeploying a previously deployed service assembly.
• Querying deployed service assemblies:
  • For all components in the system.
  • For a particular component.
  Control the state of deployed service assemblies:
  • Start the service units that contained in the SA.
  • Stop the service units that contained in the SA.
  • Shut down the service units that contained in the SA.
• Query the service units deployed to a particular component.
• Check if a service unit is deployed to a particular component.
• Query the deployment descriptor for a particular service assembly.

See Also:

Constant Field Values

Method Detail
