Re: [Quickfix-developers] How to check for dropped socket

[Alvin W. <AW...@FF...>]

Oren,

Do you mean that if the session is off, the message will only be stored 
locally and the seq number will be increased? Next time the session is 
created, the counterparty will figure out the seq # does not match and 
therefore will ask for resend.

If that is the case, that  makes sense. However, I feel not comfortable 
assuming the message has been pushed out without any warning or exception. 
Should program be notified if it tries to send a message when the session 
is off?

Thanks
Alvin'

And you never will know.  FIX is an asynchronous protocol.  There is no 
way for it to indicate the succesful receipt of a message.  That is why 
the sequence numbers are necessary.  Your SendToTarget is returning true 
because QuickFIX was able to store your message and take responsibility 
for sending it.  It may not be able to send it right away, but it will do 
so when required by a ResendRequest.

A related question: 

It seems that I can use the static method Session.sendToTarget(Message, SessionID) successfully even when the corresponding session is not logged on. (I am 
not sure if the counterparty really receives the message in this case) 

thanks

I am using the initiator and I'd like to know how I can check if the 
socket
was dropped. (i.e. if the connection was shut down by the acceptor side)

I figure I can use these properties but I'm not 100% sure what they mean:

session.isEnabled()
If the session exists, how can it not be enabled?

session.isLoggedOn()
socket.isLoggedOn()
Are they always the same and do they mean the same thing?

Thanks,

Francis Gingras
