Subject: RE: RAC changing network interface configuration
In this case it appears that the interface to IP association is
incorrect on node 2 - the OCR itself is OK and should not require
changing. The OCR is shared and you should get the same results from
oifcfg getif from either node (would be a good first step to execute and
verify). Also verify that there are no node specific configuration set
in the OCR (olsnodes and use the -nodename (I think) of oifcfg to
verify)
In this case it would appear that you should stop nodeapps and crs on
node 2 and have that corrected i.e. plumb the correct IP on the correct
interface on node 2.

I don't have enough time to write a detailed process, but you're already
in the right neighborhood. The oifcfg utility has another argument
(setif) that can be used to change the interface configuration. You'll
find some notes on using oifcfg in the documentation, so I suggest you
start there.

I have 11g RAC setup on Oracle Linux.
When I booted up the servers, node one has:
1. eth0 as a clustering_Interconnect (192.168.1.x)
2. eth1 as Global Public (137.78.225.x)
However, node two has the opposite:
1. eth0 as Global Public (137.78.225.x)
2. eth1 as clustering_interconnect (192.168.1.x)
I used this command to display the information from the OCR file:
>oifcfg getif
eth0 192.168.1.0 global cluster_interconnect
eth1 137.78.225.0 global public
The question is, is there a way to change the assignment of these
network interfaces of one server to match the other server?
Please outline the procedure in details or point me to a document on how
this is done.
Thanks.
