The IP services file must have an entry for Teradata QS if the system is to be used as a Teradata QS server. The following entry is made in this file during Teradata QS Server installation:
tqs 3000/tcp # TQS Listener port
3000 is the default port number. However, it can be changed during installation. But if different service port numbers are used on various Teradata QS server nodes, only those PC clients knowing a particular Teradata QS server node’s service port can access it.
