The last reply to this question presumed the original post was about 9i and 10g RAC in the same cluster. If this is not a request for information about doing so with Linux, you will have to seek out more information about the libskgxn.so implementation on your platform (e.g., integrated with MC/Service Guard, HACMP, Veritas, etc).

As for Linux, we do have a lot of large clusters (>8nodes) that run 9i and 10g
simultaneously. It is not a problem, once you get it set up.

Do yourself a favor and install 10g first, otherwise the 10g installer will "detect" 9i out there and force-feed a bizarre attempt to upgrade the 9i OCMS to 10g CRS (or in the oracle vernacular, "Clusterware").

If you must install 10g after 9i, make sure to shutdown OCMS and rename all the files that point to the 9i environment (e.g., srvConfig.loc,
orainst.loc, etc.)

I cover a little of this in one of our 10g RAC Install Guides which uses a
10 node install as its model. Linux, of course: http://ftp.novell.com/partners/oracle/docs/10gRAC-SLES9-POLYSERVE.pdf

	There is a link to a white paper on how this is done on the RAC

SIG website at www.oracleracsig.org

Arun:

You can have 9i and 10g on the same node. But 9i will use the 9i

clusterware and 10g will use the CRS. It is possible and I can help

you if you provide the OS details.
