How to config IP for a memory channel card in VMS ?

[Moca_Huang]

Dears:
I would like install Oracle9i RAC in VMS.
and we would like use memory channel to be interlink.
Oracle DB need the IP address of interlink.
Does VMS can set ip for a memory channel card and how to do?
Thanks.

Moca,

I'm fairly sure MemoryChannel can only be used as a cluster interconnect, not as a network interconnect.

If it *is* possible, then execute TCPIP$CONFIG select:

option 1 "Core environment"
option 2 "Interfaces"

If the interface is offered, go ahead and configure it.

FWIW, in the past it has been possible to configure networks in odd places, for example, you could run DECnet over a CI adapter. However, although CI was technically faster than ethernet, the performance was not as good on CI - something to do with packet sizes.

In a galaxy environment, you can configure a pseudo network adapter in shared memory. Perhaps this is what you're thinking of?

Although MemoryChannel is still a supported cluster interconnect, these days the conventional wisdom is to use network adapters (*much* more "bang for buck"), unless there is a very compelling reason to go with MemoryChannel.

on this mirror of the doc, I see at

Guidelines for OpenVMS Cluster Configurations

4.6 Fibre Channel Interconnect

Fibre Channel is a high-performance ANSI standard network and storage interconnect

and

4.7 MEMORY CHANNEL Interconnect

MEMORY CHANNEL is a high-performance cluster interconnect technology for PCI-based Alpha systems.

so memory channel is ONLY a Cluster Interconnect and not a network interconnect.

I was 100 % that John was correct, but it is even better when it is "official" in the reference doc :-)
