If you want to temporarily prevent the server from accepting requests on one of its ports, you can disable that port. This action blocks incoming requests from reaching the server. When a port is disabled, clients receive an error message when they issue requests to it. Later, you can enable the port. If you shut down and restart the server, the port remains disabled until an administrator enables it. Disabling a port is a convenient way to eliminate developer access to an Integration Server once it goes into production.

Another way to enable or disable a port is to enable or disable the package associated with the port. You can associate a package with a specific port so that when you replicate the package, it continues to use a port with the same number on the new server. When a package is associated with a port, enabling the package enables the port and disabling the package disables the port.
