There is no formal shutdown procedure for Prizm Gateway™. The processes are simply stopped from the TACL command line. You must be logged in as the user who started the process or as SUPER.SUPER. For example, if you specified $PZMON as the name of the monitor process when you started it, the following command stops the process:
tacl > stop $PZMON
When the gateway processes are stopped, any TCP/IP connections to it are terminated immediately.
