I would like to try to modify the source to allow multiple gateways to write this information to a central database, but I'm having a bit of a hard time finding the calls in the code.I believe this is done through an Access Security hook, so the gateway calls an asLib routine to check rights and that calls back into the hook routine. If you look at the documentation for asLib in the Application Developers' Guide you should find something about that, but if not ask again and I'll go hunting.Right, at least that is how it is done on the IOC. You can even configure put logging in the access security configuration file; IIRC the gateway has such a file, too. Correct. As the Gateway uses the same access security library as the IOC, to use caPutLog you would have to link the Gateway against the caPutLog code compiled for your architecture, and probably call caPutLog's initialization routine manually somewhere from within main() or one of the main classes to make sure caPutLog registers with access security early enough. Once you have it working, please send a patch and/or a description, as others might want to do the same and could benefit from your work. That's probably at least worth a readme or a page on the wiki. Good luck! Ralph
