Checking your article
(http://orainternals.wordpress.com/2009/06/20/rac-parallel-query-and-udpsnoop/)
and found that one of the recommendation is PARALLEL_INSTANCE_GROUP.What is
best way to check and your expert view on it.

AWR report is a good starting point. x$ksxp_client / dba_hist_ic_client_stats
/ dba_hist_ic_device_stats are some of the views that you can query to get
interconnect traffic at client/device level.
But, you really have to start in AWR report to understand global cache
workload. Then decide if your interconnect hardware is handling the traffic
well or not. Since PQ workload is captured in x$ksxp_client from 11g onwards,
you could use dba_hist_ic_client_stats view to differentiate workload at
client level.
Of course, at OS level, netstat can be used. In Solaris, I like the script
netstatMulti in this
page:http://developers.sun.com/solaris/articles/kstat_part2.html
