Flow Engine : "object disconnected from client" in Flow Engine (RPC Unavailable)


Keywords: design manager, flow engine, disconnected, client, server, map, par, rpc

Urgency: HOT

General Description:

While running any part of the flow in Windows NT (NGDBUILD,
Map, PAR, Timing, BitGen) one of the following two error messages
may appear :

"RPC unavailable"
"The object invoked has been diconnected from it's client".

The implementation window then stays up until you close it. Clicking on
the stop button brings up the dialog window to confirm abort, but doesn't
seem to have any effect.

This error will only occur in the GUI. Running the tools via the
command line will not return this error.


The machine may not have TCP/IP installed.

- Go to Start-->Settings-->Control Panel and select the Network icon.

- Install the TCP/IP protocol from the NT installation disk. This must be
installed even if the machine will not be accessing a network.
