About the Primary Port
The primary port is an HTTP or HTTPS port that you designate as the main listening port for Integration Server. The server does not reserve the primary port for any special purpose. However, Integration Server will never allow the primary port to be deleted, which guarantees that at least one port is always available.
If a primary port is not specified, Integration Server creates one at start up. By default, Integration Server designates an HTTP port at 5555 as the primary port. If you created multiple Integration Servers on the same machine, you specified a unique primary port number for each server instance during the instance creation process.
The primary port number is also the port number that clients receive when they query your server property watt.server.port .
Note: If you change
Integration Server’s primary port number after configuring the
Broker, the
Broker client for your
Integration Server may become unsynchronized with your
Integration Server’s configuration. After changing the primary port, you need to synchronize your
Broker clients to the
Integration Server’s new port configuration. For more information, see
Synchronizing Broker Clients When the Primary Port for Integration Server Changes.
