When to Use

When a fault is thrown inside a scope or process, a fault handler associated with the scope or process should be run, but before that all the running activities inside the faulted scope or process should be terminated. If a faulted scope or process has any enclosed scopes which are still running, they also should be terminated. Terminating a scope means terminating activities inside it and executing the termination handler associated with the scope.

Note that a scope can be terminated only if, it is either running normally, is running its compensation handler or termination handler. A completed scope as well as a scope that is faulted or is running its fault handlers cannot be terminated.

The termination handler is a container for the activities that will be performed in case a scope is terminated. You can add one termination handler for a scope.

If a fault occurs inside the termination handler of a scope, the fault is not propagated to the enclosing scope.
