When installing CA IDMS v19.0 Web Services, is a unique port required?
The installation process of Web Services will automatically update the sysgen definition with a new ”listener” pterm/lterm pair that is devoted to Web Services, called TCPWSRV. It will also add programs RHDCNP3W & the IDMSWSRV to the current system definition.
Each distinct “listener" pterm/lterm definition requires a unique port number. Because the Web Services is delivered with its own “listener” definitions, those must be modified to specify a unique port number for Web services use. The port-number/host-name (or IP address) combination must be unique across the LPAR. This means that a port assigned to a listener pterm cannot be shared across CVs within the same LPAR.
