Not sure about the Gap Fill, but from my experience a Resend Message is
send when for a particular sequence number, the QFJ received a message
which had something wrong with it (invalid or missing fields, for
example). So it asks the counterparty to send it once more with the
administrative Resend Message.

So, say, for seqno=40 it received a message with invalid XML data length
field 212.  (this is what happened to me). Then QFJ sends a Resend Message
asking the counterparty to send it again what was send for seqno=40. In
practice, once all the messaging has been stabilized and correctly
formatted messages are being sent and received, this should never happen
(unless, possibly, there is a fault with the network). The way you tell if
there was something wrong with the message, is that QFJ prints something
like "SEVERE: .. ".

Hope this helps.

Subject: [Quickfixj-users] Few questions of a beginer...

 

Hi all as i mentioned i'm a beginer but...

i allready made my own acceptor using the "Aplication" Interface.

actualy it's working fine but...

when it dosn't work properly i don't know how exactly to find what was
wrong .Most of my problem is with all the gapfill and resend messages
which being handeled by the QuickFixJ engine.

 

i was trying to find out some more documantation about the following
issues :

- when exactly a a Resend Message is being sent ?

- while Gap Fill is being sent : does it sent all the messages from the
last one that recieved OK (what about keep alive messages). or it just
send the next MsgSeqNun of the next message to be send.

- concerning the sesion time - can i set it to be GMT without changing the
server time?.

 

 

as a metter of fact i need some redirection to (detailed) documantation of
this stuff if there any.

Of course if there is none i'll be glad to get some answers.

 

thanks and regards.

 

shamir.
