DCE/NCS RPC server processes
ITO heartbeat polling
ITO assigns port numbers dynamically to those processes that are
granted an RPC connection. The port numbers are configurable and are
checked against the range defined in the GUI each time an RPC server
registers itself. Information relating to the assignment of ITO-specific
port numbers may be found in:
the llbd (for NCS)
the rpcd/ dced (for DCE)
NCS agents will not run on managed nodes where a DCE agent is
installed and running unless NCS support is built into the rpcd/ dced.
Table 10-8 on page 445 lists the ports that ITO requires. For more
information on port restrictions in a firewall environment, see Figure
10-2 on page 449.

If a service request for a port number within the range specified is
refused because none is available, the process will not start. If such an
occurrence arises, you can stop the ITO server processes and use the
utility /opt/OV/bin/OpC/utils/opc_reset_ports to delete the
