This may be also because of generic code which needs to handle situations where listener can not perform direct connection handoff and has to request the client to reconnect to the new socket. Oracle may be using the same codepath for both cases…

Slavik, probably. I always thinked about this “RESEND” packet as “I’m running what you wanted and connected to it and now please say the same thing to it”.

Dennis, thanks for the reply. I guess it makes sense.
But isn’t the listener spawning the correct dedicated server process based on the service request?
I guess that this is required because the instance can support multiple services, right?

Cheers,

The first CONNECT packet is for Listener, the second is for Oracle instance…
