To start or stop applications

Use the following options on the Veritas High Availabilitytab to control the status of the configured application and the associated components or component groups (application instances).

Note that the Start and Stop links are dimmed in the following cases:

  • If you have not configured any associated components or component groups (resources or service groups) for monitoring

  • If the application is in maintenance mode

  • If no system exists in the cluster, where the application is not already started or stopped as required.

To start an application

  1. In the appropriate row of the application table, click Start.
  2. If the application (service group) is of the failover type, on the Start Application panel, click Any system. VCS uses predefined policies to decide the system where to start the application.

    If the application (service group) is of the parallel type, on the Start Application panel, click All systems. VCS starts the application on all required systems, where the service group is configured.

    Note:

    Based on service group type, either the Any system or the All Systems link automatically appears.

    To learn more about policies, and parallel and failover service groups, see the Cluster Server Administrator's Guide.

    If you want to specify the system where you want to start the application, click User selected system, and then click the appropriate system.

  3. If the application that you want to start requires other applications or component groups (service groups) to start in a specific order, then check the Start the dependent components in order check box, and then click OK.

To stop an application

  1. In the appropriate row of the application table, click Stop.
  2. If the application (service group) is of the failover type, in the Stop Application Panel, click Any system. VCS selects the appropriate system to stop the application.

    If the application (service group) is of the parallel type, in the Stop Application Panel click All systems. VCS stops the application on all configured systems.

    Note:

    Based on service group type, either the Any system or the All Systems link automatically appears.

    To learn more about parallel and failover service groups, see the Cluster Server Administrator's Guide.

    If you want to specify the system, where you want to stop the application, click User selected system, and then click the appropriate system.

  3. If the application that you want to stop requires other applications or component groups (service groups) to stop in a specific order, then check the Stop the dependent components in order check box, and then click OK.
