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

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.

Tip: 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.
  • Example 1:
    1. On system A, create a cell profile that includes Dmgr and AppSrv01 (Node1).
    2. On system B, create AppSrv01 and federate AppSrv01 (Node2) to Dmgr on system A.
    3. Create server1 on Node1 and server2 on Node2.
    4. The server1 server and server2 server might contain duplicate server endpoint ports in the serverindex.xml file because Node1 and Node2 are located on different host systems.
  • Example 2:
    1. On system A, create a cell profile that includes Dmgr and AppSrv01 (Node1).
    2. On system B, create AppSrv01 and federate AppSrv01 (Node2) to Dmgr on system A.
    3. On system B, create JobManager.
    4. Create a cluster and add two servers, server1 on Node1 and server2 on Node2.
    5. The server2 server and the JobManager server might contain duplicate server endpoint ports in the serverindex.xml file because server2 and JobManager are in cross profiles. The server2 server is under Dmgr, JobManager is under the JobManager profile. and the Dmgr and JobManager profiles are located on different machines.

About this task

Procedure

  1. Review the port number settings, especially when you are planning to coexist.
  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.

      Read the "manageprofiles command" article in the information center for more information.

    • During profile creation using the Profile Management tool, you can accept the port settings recommended by the tool or you can specify your port settings.

      Read the "Creating profiles using the graphical user interface" article in the information center for more information.

    You can perform one of the following actions to change port settings after installation:
    • Use the updatePorts tool to change port settings.

      Read the "Updating ports in an existing profile" article in the information center for more information.

      Read the "Port number settings in WebSphere Application Server versions" article in the information center for more information.

    • Edit the profile_root/config/cells/cell_name/nodes/node_name/serverindex.xml file to change the port settings, or use scripting to change the values.
