[Quickfix-developers] ResendRequest help!

[SteveGoodsell <ste...@ff...>]

Hi,

Our application is using an acceptor, and basically sends trades to clients
as they come through the system. Fairly straight forward. (Using the Java
toolkit)

The problem I am seeing is this:
If the sequence numbers get out of sync for some reason I get the
ResendRequest event in the fromAdmin() section of the application. I do
nothing here, it appears that QuickFix handles all of this for us, I can see
the messages being resent to the client in mylogging.

But.. Sometimes the client is in the middle of receiving a large number of
messages when this event occurs. At this point, the client stops responding
(ACK) to the messages being sent both from the QuickFix engine and from my
side of the application. 

If this event occurs when a client logs in, then the messages are sent, the
client system acks these and all is well, the client is able to receive and
ack any new messages. But when it occurs during a bulk send, then it all
seems to stop working!

Should I be halting all my application based messages until the resend
request completes? How can I tell when this complete?

My experience in the QuickFIX api is not that great, so any advice would be
gratefully received.

Steve

What sort of ACK are you talking about?  FIX doesn't have any sort of
protocol-level ACKing.

Is this client yours?  Can you see what is happening in that
application?  If not, there isn't much you can do.  Is this causing
any problems with your Acceptor, or just the quiet "death" of the
client app?

That really shouldn't be necessary, given well behaved applications.

Hi Caleb,

We are generating TradeCaptureReports and sending them to the FIX clients.
The clients are required to then respond with a TradeCaptureReportAck. This
works fine till we encounter the resent request event, then once the
messages have been resentr (by the quick fix api) the TradeCaptureReports
are no longer being received (or reported as received in toApp on the client
side). Forcing a log off and log on again sorts this out.

I have to stress that this happens when the app is under heavy load (1 msg
per 0.5secs) and that was why I was wondering if I have to hold off on the
sending of our app generated messages until the resendrequest is finished.

It could be, as you sort of suggested, down to my coding too :)

C:\QuickFix\quickfixj\lib\backport-util-concurrent-2.0.jar;
C:\QuickFix\quickfixj\lib\mina-0.8.2.jar;
C:\QuickFix\quickfixj\lib\slf4j-jdk14-1.0-rc5.jar


I tried to run the executor .bat
under C:\QuickFix\quickfixj\bin

executor. bat has nothing great it runs this class
java quickfix.examples.executor.Executor

I get this exception

Exception in thread "main" java.lang.NoClassDefFoundError: edu/emory/mathcs/backport/java/util/concurrent/ThreadFactory
        at quickfix.examples.executor.Executor.main(Executor.java:51)


Can anybody help me on this?. I know its not able to find some threadfactory class but where is it?.

Thanks
