Some good Experience for Me today.Early in the Morning ……
One of Our RAC node filled up with 100% CPU usage.As part of Investigation We found that this was because of racgmain Process.
It was filled-up with more than 250 racgmain process which are consuming CPU a lot.Due this Our System got Very slow.
To avoid this, we should apply latest patch which is > 10.2.0.5 and CRS patch too.There was a temporary workaround for this ..you can see that in Metalink Doc ID 732086.1 and ID 6196746.8
