Alex, The SenderCompID is a listed attribute and appears editable, but I have not attempted to change this as it is assigned in the "Settings" file and we have no need to change it on the fly. Regarding management... make sure you have made necessary code changes depending on your version of Java as described in the user manual. The "jconsole" application is in the java installation "bin" subdirectory. Just run it (you do not need any parameters). It would probably be best if you run it on the same machine as your FIX application under the same user. The process ID will be listed and all you have to do is select it and click "connect". You can also run it remotely, but you will probably need to open firewall ports. I hope that helps. -Tommy On Apr 27, 2007, at 5:12 AM, Alex McGlashan wrote: > QuickFIX/J Documentation: http://www.quickfixj.org/documentation/ > QuickFIX/J Support: http://www.quickfixj.org/support/ > Hi Tommy, > > I was interested to read your note below about updating session > attributes on the fly.
