We do not recommend or support having more than one Genie Server application and Genie database on the same machine running concurrently.
This is simply due to the myriad of things that could go wrong. The Genie application requires exclusive access to various ports, and if you intend to run multiple Genie applications on the one machine, additional configuration of ports is required. If these are not configured correctly, several areas of Genie may not function as expected or at all.
You may also potentially have Genie Clients connecting to the wrong Genie Server and accessing the wrong data file, or perhaps incorrectly updating the wrong Genie database depending on your update process.
