We have 3 node RAC. In one of the node clusterware is down and also CSSD process is down. I got to know that we have to clear socket files in that node.
Please let me know what needs to be done instead ofclearing socket files.
Please find db details

why do you need to even clear the sockets file.... just bring down the crs and start it up again... if you face the same issue again... then check the alert log to find out what is actually going on...
