Check for port conflicts

WebSphere Application Server may not run properly if you have port conflicts. For example, your server may not start. The port validator verifies your configuration to ensure that you do not have port conflicts across WebSphere Application Server instances and products. It detects port conflicts between:

• Instances in a Version 4 product or a Version 5 product.
• Servers in a Version 4 product or a Version 5 product.
• Instances in different Version 4 and Version 5 products (Version 4 Advanced Edition, Version 4 Advanced Edition Single Server, Version 5 Base, Version 5 Network Deployment, and Version 5 Express).

To run the port validator, run the servicetools script from the Qshell command line and specify the -portconflict parameter.

1. On the OS/400 command line, enter the STRQSH (Start Qshell) command.
2. On the Qshell command line, use the cd command to change to the directory that contains the script:

   cd /QIBM/ProdData/WebAS5/edition/bin

   where edition is Base for WebSphere Application Server and ND for WebSphere Application Server Network Deployment.

3. Run the servicetools script to check for port conflicts:

   servicetools -portconflict -products all
