One component of ToolTalk is the ToolTalk database server, /usr/dt/bin/rpc.ttdbserver.
The ToolTalk database server is used by the ToolTalk messaging service and for file-name mapping. It is usually registered in /etc/inetd.conf when the desktop is installed and needs no additional configuration.
For more information on the ToolTalk database server and its configuration options, see the rpc.ttdbserver(1M) man page.
