We are using RAC 10.2, with 2 nodes on AIX 5L. Two nodes has the same configuration except node 2 has installed the OEM.
Attach with the log file. Pls tell me the way to verify the reason why node 2 reboots frequently succeddently.
Thanks alot.

If you are having node evictions, it is the clusterware alert logs (both nodes, please) that you should be looking at, not the instance alert log. It is your $CRS_HOME/log/nodename/alert<nodename>.log file.
(edit - typo)

Have you set your diagwait css parameter? If not, you'd better do so now, then you might get better information in your logs next time. It's described in metalink note 559365.1.
And by the way, no-one can help you with this sort of problem if you don't give the exact release number of your products, "10.2" is not precise enough.

Thank you for your information. I'll take a look at metalink note right now. Will upload more diag file.
My oracle version is 10.2.0.4.0, sorry for my mistake.
Should I take care to anything else? After looking at the ocssd.log, I found nothing cos I don't understand this log.

Hi Babu,
We can't upload .rar file in this forum, therefore I change .rar file to .log file.
Once download, please remove .log file in the end and it becomes the .rar file. Unzip this file and pls check the log.
Thank for your help.
