Configuring port settings
When you configure WebSphere® Application Server resources or assign port numbers to other applications, you must avoid conflicts with other assigned ports. In addition, you must explicitly enable access to particular port numbers when you configure a firewall.
Before you begin
Tips:
- 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. The default dynamic port ranges for pre-2008 operating system is 1025 to 5000 , and the dynamic port ranges for newer operating systems is 49152 to 65535. Because these default ranges are recommended by the Internet Assigned Numbers Authority (IANA), they are common across all operating systems.
- Port conflicts might occur if you install WebSphere Application
Server on multiple systems with deployment managers managing servers
or clusters on different systems. The configuration-service port-resolution
mechanism does not support cross profiles on different host machines.
