Resolution:
Whether the COM Adapter works synchronously or asyncrhonously depends on how
you configure the COM Adapter. For example, if you set up an RV RPC Client
in the Interceptor and an RV RPC Server in the Service and have the
Interceptor send RPC requests to the Service, then messaging is synchronous.
That is, the Interceptor will block until the reply comes back from the
Service. On the other hand, if you set up an RV Publisher in the Interceptor
and an RV Subscriber in the Service component and have the Interceptor send
messages to the Service, then messaging is asynchronous. That is, the
Interceptor will return as soon as the message is sent. If you configure the
Interceptor to use certified messaging, the Service doesn't even have to be
up when the Interceptor sends the message. When the Service comes up, the
Interceptor will deliver the message.
