James works as a senior DBA for a finance company. He plans to implement a test RAC
environment. As per his plan, a three-node RAC would be implemented on a Windows platform,
with the following points related to the storage of files:
1) A single Oracle home would be shared by all the nodes.
2) The data files will extend automatically because the autoextend feature will be enabled.
3) The Oracle binaries and all the database files would be stored in a single file system.
4) The hardware RAID is used to support high availability.
These are the some of the storage options available for RAC implementation:
Option 1:Use OCFS with ASM Option 2:Use ASM and not OCFS Option 3:Use OCFS and not ASM Option 4:Use neither OCFS, nor ASM
Which storage option would you suggest for this plan?

Over a six-month period, you have been regularly monitoring your four-instance RAC database,
which is running on the first 4 nodes of a 6-node cluster, by using ADDM and by monitoring well-
known combinations of wait event and statistics in AWR reports.
Two weeks ago, a newer version of your main application went live. Starting last week, you
noticed a large increase in CPU time (consumed by the three application services on your RAC
database) due to increased workload.
The OLTP and DSS services have not had a decrease in the percentage of time spent using CPU.
However, for the BATCH service the percentage of time spent using CPU has gone down and the
wait-time percentage has increased.
You want to recommend a tuning exercise to your team. Which two recommendations would you
make first, based on the symptoms described? (Choose two.)
