Dear Experts,
We need urgent help please, as we are facing very low performance in production database.
We are having oracle 11G RAC on HP Unix environment. Following is the ADDM report. Kindly check and please help me to figure it out the issue and resolve it at earliest.

Analysis Target
---------------
Database 'MCMSDRAC' with DB ID 2894940361.
Database version 11.2.0.1.0.
ADDM performed an analysis of instance mcmsdrac1, numbered 1 and hosted at
mcmsdbl1.

Findings and Recommendations
----------------------------
Finding 1: CPU Usage
Impact is 1.44 active sessions, 27.08% of total activity.
---------------------------------------------------------
Host CPU was a bottleneck and the instance was consuming 99% of the host CPU.
All wait times will be inflated by wait for CPU.
Host CPU consumption was 99%.
Recommendation 1: Host Configuration
Estimated benefit is 1.44 active sessions, 27.08% of total activity.
--------------------------------------------------------------------
Action
Consider adding more CPUs to the host or adding instances serving the
database on other hosts.
Action
Session CPU consumption was throttled by the Oracle Resource Manager.
Consider revising the resource plan that was active during the analysis
period.
Finding 2: Interconnect Latency
Impact is .07 active sessions, 1.33% of total activity.
-------------------------------------------------------
Higher than expected latency of the cluster interconnect was responsible for
significant database time on this instance.
The instance was consuming 110 kilo bits per second of interconnect bandwidth.
20% of this interconnect bandwidth was used for global cache messaging, 21%
for parallel query messaging and 7% for database lock management.
The average latency for 8K interconnect messages was 42153 microseconds.
The instance is using the private interconnect device "lan2" with IP address
172.16.200.71 and source "Oracle Cluster Repository".
The device "lan2" was used for 100% of interconnect traffic and experienced 0
send or receive errors during the analysis period.
Recommendation 1: Host Configuration
Estimated benefit is .07 active sessions, 1.33% of total activity.
------------------------------------------------------------------
Action
Investigate cause of high network interconnect latency between database
instances. Oracle's recommended solution is to use a high speed
dedicated network.
Action
Check the configuration of the cluster interconnect. Check OS setup like
adapter setting, firmware and driver release. Check that the OS's socket
receive buffers are large enough to store an entire multiblock read. The
value of parameter "db_file_multiblock_read_count" may be decreased as a
workaround.
