Looking for AT&T 'RTR' op.sys. info

[dwight at timeb.UUCP]

	We're seriously considering the implementation of a 3B20-based
large system here. In our dealings with the AT&T sales people, they
refer to an operating system for the 3B boxes that they call "RTR".
We have never heard of it before, and, being sales people, they don't
seem to know too much about it. They claim it's bundled with the 3B
equipment, and that no separate licensing is necessary. They allude to
various 'real-time' capabilities of this operating system, claim it's
based on System V (which we're currently running on a pair of VAXen--
release two), and they sayd that it offers 'fault tolerance.' Having
some exposure to fault-tolerance operating systems (like Tandem's
Guardian), this is both attractive and repulsive--we certainly do need
some kind of fault tolerance in this application, but I'm afraid that
a Unix variant running in a fault-tolerant mode could get rather slow,
depending on the checkpointing algorithm involved.
	Is anyone running RTR? If so, can you tell me a little about it?
	Does anyone know how well it performs compared to standard
Unix System V Release 2? Is there any benchmarking information available?
	Does anyone know how much trouble it would be for us to port
a lot of code we've developed for System V to an RTR opsys?
	Does anyone know if RTR source licenses are available?
	Can anyone provide any confirmation--or lack thereof--for
the sales peoples' claims that RTR comes bundled with a 3B20 purchase?
	Thanks in advance! If I receive several replies, I'll post
a summary here.
