Hi,
I'm looking for a documentation of the wire protocol between MCA's.
another solution is an open source implementation of channels.

Hi Ophir,
I don't think you will find the protocol specs anywhere that inside IBMs labs. And that is for one major reason, if it was availabe to all of us, we would start code utils to communicate direcly to MQSeries, and that would cause trouble if IBM chooses to change anything in the protocol.
It's the same reason for not publicate anything inside the MQ, just give us the API. Personally I think it's a good strategy, because some years ago when to big OS was called MVS/XA, any systemprogrammer was using some RESERVED bits in the operating system, and when IBM, released a patch, it didn't work....
And ofcause IBM was blamed by CEOs.... Well thats my personal opinion.
If the internal specs was available I would like to see them aswell. How the locks are done, the log writing etc.
Just my $0.02

Although I 100% agree with the opinion of Jorgen, I am wondering how Microsoft has implemented the MQSeries-MSMQ bridge (well in fact I think that it was developped by Level8).
If I remember well (I received a presentation some years ago), Microsoft explained that the MSMQ->MQ integration was performed by using the plain API (client), and the MQ->MSMQ integration was performed using MQ channels.
Has anybody ever heard about this?

This is right, Microsoft have implemented the Bridge using standard API's, what the realy are doing is getting messages of XMIT queues bacause they then get's the information about the target queue in the XMIT header.
I've planned to check the MSMQ bridge, but this might be cancelled due to company takeover.....
