Switching an application

To gracefully switch an application from one system to another, perform the following steps in the application table of the dashboard.

Note:

You can switch an application only if the application monitoring configuration includes one or more failover systems.

To switch an application

  1. Filter the applications that you want to switch to another node.

    See Searching for application instances by using filters.

    The application table displays all the instances of the filtered applications.

  2. If required, select multiple applications or instances to perform a batch operation.

    See Selecting multiple applications for batch operations.

  3. To switch the applications, in the taskbar, click the appropriate icon (use the tool tip to recognize the appropriate icon).
  4. In the Switch Application panel, select the systems where you want to switch the applications, and then click OK. Cluster Server takes the applications offline on the existing systems, and brings them online on the systems that you specified.
