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.
Procedure
- Review the port number settings, especially when you are planning
to coexist.
You can use
the dspwasinst command-line tool to display the
port information for a profile.
- Optional: Change the port number settings.
During installation, you can use the Installation wizard.
You can set port numbers when configuring (customizing)
the product after installation. Start thinking about port numbers during the
planning phase.
