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
For more information about port numbers
that your iSeries® system currently uses, enter the
NETSTAT *CNN command on the command line. Press F14 to view
assigned port numbers.
You can also use the port validator tool
to find port conflicts between different WebSphere Application
Server profiles, products, and servers. Read the "port validator tool"
article in the information center for more information.
Procedure
- Review the port number settings, especially when you are
planning to coexist.
