Package Associations for Ports
All ports are associated with a package. By default, ports are associated with the WmRoot package.You can associate all port types except the diagnostic port with an application package. By doing so, when you replicate the package, the package continues to use a port with the same number on the new server. This feature is useful if you create an application that expects input on a specific port. The application will continue to work after it is replicated to another server.
When the package to which a port is assigned is disabled, the port is disabled as well. The port is re-enabled when the package activates successfully.While the port is disabled, access to services or other resources through those ports will fail until the port is successfully enabled. If you plan to use hot deployment for packages, you may want to avoid associating ports with packages that will be updated via hot deployment. This will avoid the situation where the port and its resources are not available when Integration Server unloads the package during hot deployment.
Important: Be careful when setting up a port that is associated with a package. When copied to the target server, the new port might decrease security on that system. For example, suppose you replicate a package that is associated with an HTTP port at 5556. The replication process creates an HTTP port at 5556 on the target server. If the target server normally uses only HTTPS ports because of their greater security, then the new port presents a possible security hole on that server.
