Set Port Numbers

Set Port Numbers

For a standard, single instance of InterSystems IRIS, the superserver port number is 1972 by default. For multiple instances of InterSystems IRIS on a single machine, each must have a unique superserver port number. During installation, subsequent instances are assigned a port if you choose to set it automatically, or you can manually enter port numbers during the installation.

You most likely do not need to change the superserver port numbers because of the way the InterSystems IRIS installation assigns them. You can change the superserver port value after installation from the Memory and Startup page (System Administration > Configuration > System Configuration > Memory and Startup) of the Management Portal.

You do need to assign each instance a unique Telnet port number. You can change the Telnet port values after installation from the Startup Settings page (System Administration > Configuration > Additional Settings > Startup) and the Telnet Settings page (System Administration > Configuration > Device Settings > Telnet Settings), respectively, of the Management Portal.
