Chapter 11 Certified Message Delivery : Certified Delivery Features

Certified Delivery Features
Rendezvous certified message delivery software offers stronger delivery assurances than standard Rendezvous reliable delivery.
Certified delivery assures programs that every certified message reaches each intended recipient—in the order sent. When delivery is not possible, both sending and listening programs receive explicit information about each undelivered message.
Programs determine an explicit time limit for each message.
Sending programs can disallow certified delivery to specific listener transports.
Once a program sends a certified message, Rendezvous software continues delivery attempts until delivery succeeds, or until the message’s time limit expires.
Rendezvous certified delivery software presents advisory messages to inform programs of every significant event relating to delivery.
Rendezvous certified delivery software records the status of each message in a ledger. For programs that require certification only for the duration of the program process, choose a process-based ledger. For programs that require certification that transcends process termination and program restart, choose a file-based ledger.
Certified delivery meshes smoothly with standard Rendezvous communications. When certified delivery is disallowed, delivery conditions degrade gracefully to the standard Rendezvous reliable delivery semantics.
