Stopping Messages that Require Routing
When upgrading a non-redundant (and so, non-fault-tolerant) routing daemon, stopping that daemon completely stops message forwarding. If correct operation of the application processes depends upon continuous message forwarding, then stop all dependent applications before upgrading that routing daemon.
If any dependent applications use the Rendezvous certified message facility (RVCM), first ensure that all certified messages have been delivered to all certified listeners, before you stop these application processes. (For more information, see the DELIVERY.COMPLETE advisory in .) After cleanly stopping all the processes that use RVCM, we recommend that you make backup copies of all RVCM ledger files.
