I have created a Fix application using 'QuickFIX/n is v1.4.0' from this 'http://www.quickfixn.org/download' site. When I executed an application,i randomly get error of sequence number.Sometimes the application runs fine and sometime I get sequence number problem.The log details are as below:

when i keep the following settings in config file , it works fine.The settings are as follows :
ResetOnLogon=Y
ResetOnLogout=Y
ResetOnDisconnect=Y
I want it to work for following settings in config file.The settings are as follows:
ResetOnLogon=N
ResetOnLogout=N
ResetOnDisconnect=N
Please kindly send me suggestions and settings to run this application without errors.
Thanks and Reguards, Vishwesh Raval.
回答1:
Your sequence numbers are out of sync. The output you pasted says that pretty clearly.
I suggest you do some reading about FIX protocol. The unfocused nature of your question indicates that you don't know much about it. QuickFIX/n will be much easier to use and ask questions about if you spend some time learning about how the protocol actually works. It's a pretty simple protocol.
回答2:
the error message
MsgSeqNum too low, expecting XX but received YY
is related to the policy between your client and the remote server. Some servers require a Reset at every logon, while others just once a day or once a week. If you are writing a sample application just for learning the protocol, try to add this line in your config file:
ResetOnLogon=Y
But, first of all, try to spend some time to learn the protocol.
