{{Quickfixn}} [SPAM] Re: Checksum problem

[Christophe Lucas]

The target system is not our implementation. This security list  is our only possibility to retrieve programmatically  the securities we can trade on their platform as we would like to synchronize each night their list with ours. I cannot see a possibility to break this message up. The security list message has got a tag '393 TotNoRelatedSym' to facilitate the breaking up of long messages, but it seems that they are not using this. I will ask if they are able to make this possible.

So far I didn't encounter problems with smaller SecurityList messages.

Meanwhile I will recompile quickfixn without the validate() line and test with this assembly.

Kind regards,
Christophe

Wow, that is a very long message.  I wonder if the excessive length is exposing a bug in QF/n.  I'm afraid I probably won't be able to find time to dig into this very soon due to my work responsibilities.

Do you have trouble with smaller SecurityList messages?

If the Target system ("DEMO-PRAG3") is your implementation, I might suggest that you break this message up into smaller messages, instead of a single 569K message.  If it's not your implementation, then that's not an option (and I kind of wonder what they're thinking).

Thank you for your fast response.
The exception it gives is : "Invalid message: Expected CheckSum=207, Received CheckSum=123"
The message itself can be found in attachment.

Importance: Low

It's commented out because the disabling of this feature is not implemented yet.

Can you provide your erroneous message and the error it gives?  That will help us log a bug and fix it.

Dear all,

I have got a problem with the checksum validation in a FIX5.0SP2 application when I receive a  SecurityList message.
The calculated checksum is not equal with the given checksum in the message.

As a quick fix, I was hoping to use the option 'ValidateLengthAndChecksum=N' , but I see that this option has been put into comment:

/** FIXME - implement optional settings
            if (settings.Has(SessionSettings.VALIDATE_LENGTH_AND_CHECKSUM))
                session.SetValidateLengthAndChecksum(settings.GetBool(SessionSettings.VALIDATE_LENGTH_AND_CHECKSUM));
*/


Can someone tell me if this is a known issue and if it is possible to comment it out again? Or are there other solutions?

Kind regards,
Christophe
