We have used, and continue to use on several grids, XML-RPC to
connect in world communicator objects to our external intelligent
systems, such as the I-X AI planner and process support aids used in I-Rooms.
The scripts run completely compatibly in SL and OpenSim.
I am not aware that XML-RPC is deprecated inSL, though the HTTP-IN
mechanism is the more modern scheme that may be more flexible. If
someone has a link to a notice that its deprrcated I would appreciate the link.
Melanie is correct that there is a potential bottleneck when using
XMLRPC in SL as the host is shared for all such usage. But it works
all the tine for us, I have never seen 50% degradation. Of course
you should have scripts that do check that communications works end
to end an not assume the services may always be up. When we
developed the software back in 2006, we used to observe a latency on
calls of around 3 to 5 seconds so allow for long communications
delays. But for the appropriate type of communications and where
queuing is okay it works fine.
The 20800 XML-RPC port needs to be open on the OpenSim.exe machine,
and remember to set the OpenSim.ini host to the REGION server, not
the ROBUST grid, if you are running in grid mode. So theer is one
XMLRPC port and service per region server instance.
