After you install DB2 Universal Database Enterprise - Extended Edition for Windows on multiple nodes, the setup process will only configure the instance owning machine to be the coordinator node for communications from client machines. To remotely administer nodes using the Control Center, you will need to enable communications on each of the nodes.
You need to update the services file and specify the port that you want the server to listen on for incoming client requests from the Control Center. The services file is located in the\winnt\system32\drivers\etc directory.
Note: | The location of the services file can depend on the products you have installed on your system. See you TCP/IP documentation for more information. |
