[Quickfix-developers] getting started - problems with example apps tradeclient and executor

[Mark L. <ma...@tr...>]

Hi everyone,

First, thanks in advance for all your help. I was introduced to quickfix 
yesterday and I know i have a lot to catch up on.

I tried running the example application of tradeclient and executor 
found in the default example directory, and it is telling me that they 
cannot create a session.

I have modified the example configurations in such a way that I know 
'tradeclient' is acting as the initiator, and 'executor' is the 
acceptor. They can hook up on the specified port, as I can see them 
sending logon messages to each other. However, logon does not finish 
correct, as things seem to break down when they try to synchronize 
sequence numbers.

In a nutshell, I have something like this

./execute execute.cfg

and then

./tradeclient tradeclient.cfg

On the execute side, I see the following printouts (Im trying my best to 
not be overly verbose)

<20080318-20:22:19, FIX.4.2:EXECUTOR->CLIENT1, event>
  (Created session)

  (Accepted connection from 127.0.0.1 on port 5001)
  (Received logon request)
  (Responding to logon request)
  (MsgSeqNum too high, expecting 1166 but received 1219)
  (Sent ResendRequest FROM: 1166 TO: 0)
  (Received SequenceReset FROM: 1166 TO: 1220)
<20080318-20:22:42, FIX.4.2:EXECUTOR->CLIENT1, event>
  (Socket Error: Connection reset by peer.)
<20080318-20:22:42, FIX.4.2:EXECUTOR->CLIENT1, event>
  (Disconnecting)


I looked on the client side and it said pretty much the same thing. The 
critical part...

<20080318-20:22:36, FIX.4.2:CLIENT1->EXECUTOR, event>
  (Received ResendRequest FROM: 1166 TO: 0)

<20080318-20:22:36, FIX.4.2:CLIENT1->EXECUTOR, event>
  (Sent SequenceReset TO: 1220)

Seems to me that tradeclient got executor's sequence number 
synchronization message, and ignored it. As a result, the session never 
gets created.

This seems very strange to me since I have not changed any code in the 
example applications. I am also running the standard configurations 
found in the cfg directory.

Does anybody have any idea what's going on? Any help would be much 
appreciated!

As a side question, any introductory reading material that would help me 
get the example apps up and running would be also appreciated.

thanks
