You can change the TPS_SERVER_LOG_PORT. This is required to avoid port conflicts or to comply with organizational network policies.
Steps
Go to: [TC_ROOT]\install\tps or the equivalent TPS configuration directory in your Teamcenter installation.
Open the TPS configuration file, for example: tpsserver.properties
Locate the parameter: TPS_SERVER_LOG_PORT
Change the port number to the value agreed with your IT/network team. Example: TPS_SERVER_LOG_PORT=45455
Save the file.
Restart the TPS service and, if required, the Teamcenter services.
Verify that:
The port is not blocked by a firewall.
No other application is using the same port.
