WAS v8.5 > Set up the application serving environment

Configure port settings page

When configuring WebSphere Application Server resources we need to avoid conflicts with other assigned ports, and explicitly enable access to particular port numbers in the firewall.

Port conflicts might occur if you install WAS 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.

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

2. Optional: Change the port number settings.

   We can set port numbers when configuring the product after installation.

   • During profile creation using the manageprofiles command, we can accept the default port values or we can specify your port settings. To specify ports, we can do so in any of the following ways:

     • Specify the use of a port file containing the port values.

     • Specify the use of a starting port value.

     • Specify the use of the default port values.

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

   We can perform one of the following actions to change port settings after installation:

   • Use the updatePorts tool to change port settings.

   • To manually change the port settings, edit...
     profile_root/config/cells/cell_name/nodes/node_name/serverindex.xml

Subtopics

• Update ports in existing profiles
  
• Host name values
