Communications across backplane between 2 hard partitions on ES80?

[David Silvers]

Can an application, say BAAN talk to another application, say Oracle across the backplane between 2 hard partitions on an ES80? Or does this sort of communication have to be done through the network?

[Hein van den Heuvel]

Sorry, no can do.
You'll have to go out and back in.
Still a Baan user huh? Cool.

Only OpenVMS with Galaxy Softpartitions will do shared memory communications. And there RDB is possibly the only solution really using that for a global cache.
I don't think they run a TCP stack over memory either.


The best documentation in this space is probably:

The GS80 website has slightly more docs than then ES80 one:

http://h18002.www1.hp.com/alphaserver/docs/userguide/WebHelp/partitions.htm?jumpid=reg_R1002_USEN

hth,
Hein.

Not as far as I know, but my knowledge of BAAN is pretty rusty. From the hardware and O/S standpoint, I don't think it's possible because there's no mechanism for shared memory or IPC between "hard" partitions in Tru64 nor does the ES architecture provide for it. I don't even think the GS systems can do that with Tru64 but IIRC, there's some functionality if you go VMS

I think you gotta go out the network stack and back in. Maybe it's time to test drive some 10gb NICs ;-)

Gee, sorry for the duplicated and vastly less informative answer. I guess if I'd read the whole thread and seen Hein's response I could have saved a few bytes of storage for HP and given you back a minute of your life. As usual, Hein has provided a correct and thorough answer. I even learned a thing or two from the docs he cites. Thanks, Hein! And, sorry David.
