Running multiple Servoy Application Servers on the same machine is fully supported, although some configuration settings are required.

The Servoy Application Server uses (by default) three ports:

• port 8080 for HTTP traffic
• port 8085 as the Tomcat SHUTDOWN port 
• port 1099 for RMI traffic to communicate with Smart Clients

When running multiple Servoy Application Servers on the same machine, to avoid conflicts, each instance needs to be configured to use unique ports to provide its services.

See HTTP Port configuration for a detailed description how to adjust the port settings of a Servoy Application Server.

Note that if multiple database instances are also hosted on the same machine, each database instance also needs to be configured to use a different port.
