Configuring ports

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

  1. 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.

  2. Optional: Change the port number settings.
    You can set port numbers when configuring the product after installation.
    • During profile creation using the manageprofiles command, you can accept the default port values or you can specify your port settings. If you want to specify ports, you can do so in any of the following ways:
      • Specify the use of a port file that contains the port values.
      • Specify the use of a starting port value.
      • Specify the use of the default port values.
    • You can use the chgwassvr command to change the ports for an application server within a profile.
