Fault Tolerance

This property page specifies the installation package sources or Application objects that Novell^® Application Launcher^TM uses as backups if this Application object is unavailable during distribution. Application Launcher tries the package sources or Application objects in the order shown in the Source List or Application List, from top to bottom.

This Fault Tolerance page does not apply to Application objects that use Microsoft* Windows* Installer (.msi) packages. For an MSI Application object, you can provide source resiliency (fault tolerance) through the use of additional source locations for the installation package (Common > Sources page).

Enable Fault Tolerance
Check this option to enable fault tolerance. The other fault tolerance options are available only if this option is enabled.

Use Source List
Select this option to have Application Launcher use a list of Package sources as the backup. You must have already created at least one installation package source (Common > Sources page). This option is not available on Application objects for Terminal Server applications or Web applications.

Add
Click Add, browse to and select a package source, then click OK to add it to the Source List.

Delete
Select a package source from the Source List, then click Delete to remove it from the Source List.

Up-Arrow and Down-Arrow
Select a package source from the Source List , then click the up-arrow to move the source up in the list or click the down-arrow to move it down in the list. Application Launcher tries the sources in the order they are listed, from top to bottom.

Use Application List
Select this option to have Application Launcher use a list of Application objects as the backup. You must have already created additional Application objects for the application, with the application files being stored on a different server or volume than this application. If the application is too busy or is not available, then Application Launcher tries each Application object in the specified order.

IMPORTANT: Only one-level-deep fault tolerance is supported. If Application Launcher fails over to one of the backup Application objects in the list and the backup Application object fails, the distribution fails even if fault tolerance has been enabled for the backup Application object.

Add
Click Add, browse to and select an Application object, then click OK to add it to the Application List.

Delete
Select an Application object from the Application List, then click Delete to remove it from the Application List.

Up-arrow and Down-arrow
Select an Application object from the Source List, then click the up-arrow to move the Application object up in the list or click the down-arrow to move it down in the list. Application Launcher tries the Application objects in the order they are listed, from top to bottom.
