You can run multiple Cyc images on a single machine, assuming it has sufficient resources, by changing the base port for (at least) one of the images. For instance, you can have one Cyc image running on base port 3600 (the default) and another on port 3620. To access the first image, point your browser to YOURMACHINENAME::3602/cgi-bin/cg?cb-start; for the second, hit YOURMACHINENAME:3622/cgi-bin/cg?cb-start. The base port value (and the per-service offset values) are configured in the init/parameters.lisp file. more ... about Can I run more than one Cyc image on a single machine?
