Port number settings

Supported configurations:

This topic is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Migration Toolkit.

Avoid trouble: Port conflicts might occur if you assign a custom port value within the recommended default dynamic port range. Because port values are assigned dynamically, WebSphere Application Server cannot predetermine the port values that will be assigned to your servers. A way to avoid the possibility of a port conflict among servers is to either accept the default server port values assigned by the Profile Management Tool, or assign custom port values that do not fall within the default dynamic port range. In operating systems released prior to 2008, the default dynamic port range is 1025 to 5000, and in newer operating systems the dynamic port range is 49152 to 65535. Because these default ranges are recommended by the Internet Assigned Numbers Authority (IANA), they are common across all operating systems.
