For performance reasons we have set up a second server instance that acts as an integrator with the campus-wide course management system (CMS). A professor can create a new course in the CMS and decide wether a dotLRN group is required or not. If yes the new group is created and all students and admins registered for the course.
This worked very well in the single server case. But now even thou a dotlrn group is created through the integrator the main system returns "file not found" because is does not know that a new dotlrn instance was mounted in the site map.
How can I update the server without restarting it?
