Hi.

I'm assisitng a DBA with an Oracle 11.2.0.2 RAC install on AIX 6.1. The install failts at the root.sh step on the second node which apears to be a know problem

http://www.ora-solutions.net/web/2010/09/29/upgradeinstall-of-grid-infrastructure-to-11-2-0-2-is-failing/

Networks are not my strong point, can some explain what route I would need to add if my RAC interconnect is using 192.168.1 addresses?

I.e. Node 1 is 192.168.1.1 and Node 2 is 192.168.1.2

Ive also see some talk that I need to ensure multicast is enabled on our cisco switch which I will do.

Lastly, I would like to use the multicast.pl but can find it, is there another AIX OS test to see if multicast is working?

Thanks :)

Me again. Ive got the mcasttest script and have run it with odd results. Its failing on once interface - the RAC interconnect. Can this be corrected with a route?

In your case, you need to apply the Oracle patch 9974223
Here is the description of the solution:

It has been found that the functionality of multicast on the 230.0.1.0 (port 42424) network address has been problematic with some network environments resulting in the issue stated above. To address this issue Oracle has released Patch: 9974223 on top of 11.2.0.2 . This patch makes use of the 224.0.0.251 (port 42424) multicast network address in addition to the 230.0.1.0 (port 42424) multicast address. Multicast must be enabled on one of these two addresses to allow for Oracle Grid Infrastructure to successfully start on all cluster nodes.

thanks
