Putting It All Together
This table summarizes how checkpoint restart, clustering, and guaranteed delivery work together to provide availability, failover, and reliability in different situations.

If the server on which the service is running becomes unavailable
Point at which the service restarts
After the server becomes available, you must manually restart the service.
At the beginning
X
After the server becomes available, the client automatically restarts the service. The client keeps trying to run the service until it runs successfully.
At the beginning
X
The client automatically retries the service on another server in the cluster. If that server fails, the client retries the service on the next server in the cluster, and so on. If all attempts fail, you must manually restart the service.

The client retries the service on the next server in the cluster. If that server fails, the client retries the service on the next server in the cluster, and so on. The client continues to try running the service until it runs successfully.
