Thanks John, Randy, folks for the support
Point (6) below got resolved by RE-starting the CRS.
6) Thereafter startup of RAC using srvctl start instance -d PNB70MB -i
"PNB70MB2" terminating After MOUNT at "SMON: enabling cache recovery".
Thus Rollback Tablespace is not brought up & Database OPEN is NOT fully
Completed. 2 corresponding .trc files are dumped with time stamp greater
that alert_PNB70MB2.log in such a case.
Still seek advice still on how to approach the 100 % sys usage issue.
NOTE - 100 % sys is observed only when doing the respective Application
transaction Run on a 3 node RAC & is NOT observed when running on NON-RAC
Database having identical data .
Cheers

Al I can think of is to stop the problematic instance using srvctl with
-o option (abort) and restart the instance again using srvctl
The next option would be to stop the database using srvctl stop database
-d PNB70MB

Folks
In a Benchmark Setup:-
STEPS
1) CPUs increased to 80 from from 24 on 1 of the RAC Nodes. CPUs
increased to 30 from 24 on 2 Other Nodes.
2) 3 RAC instances brought up normally. The 3 RAC Nodes are normal.
3) On initiating a Benchmark Application Transaction Run, % sys became
100 only on 1 Node containing 80 CPUs. (On the Other 2 Nodes normal - %
sys is normal). % sys going to 100 % seems to be an O.S. Bug.
4) RAC Instance brought down manually using "sqlplus / as sysdba" ->
"shutdown immediate" on the node showing 100 % sys usage
5) % sys immediately became normal after instance shutdown & continues
to be normal now.
6) Thereafter startup of RAC using srvctl start instance -d PNB70MB -i
"PNB70MB2" terminating After MOUNT at "SMON: enabling cache recovery".
Thus Rollback Tablespace is not brought up & Database OPEN is NOT fully
Completed. 2 corresponding .trc files are dumped with time stamp greater
that alert_PNB70MB2.log in such a case.
7) However Manual startup of the respective RAC instance using "sqlplus
/ as sysdba" -> "startup" is completing FULLY
