NO.1 A batch workload that historically completed in the maintenance window between 10:00 PM and
midnight is currently showing poor performance and completing at 2 AM.
To help in the diagnosis of the performance degradation, the senior DBA in your organization asks you to
execute the awrddrpt.sql script to produce a Compare Periods report.
Which two statements are true about the report produced by this script? (Choose two.)
A. It is refreshed automatically based on the moving window baseline.
B. It compares details between any two selected time periods of the same duration.
C. It normalizes the statistics by the amount of time spent on the database for each time period.
D. It compares details between two consecutive time periods of the same or different durations and is
refreshed every 60 minutes.

NO.2 You are working on an online transaction processing (OLTP) system. You detected free buffer waits
events for your database instance running in a machine that has multiple CPUs. You increased the
database buffer cache size as the first step. After a few hours of work on the database, further
investigation shows that the same event is being recorded.
What would be your next step to avoid this event in future?
A. Decrease the value of the DBWR_IO_SLAVES parameter.
B. Set the USE_INDIRECT_DATA_BUFFERS parameter to TRUE.
C. Increase the value of the DB_WRITER_PROCESSES parameter.
D. Increase the value of the DB_FILE_MULTIBLOCK_READ_COUNT parameter.

NO.3 View the Exhibit and examine a portion of the output obtained from the following query:
SQL> SELECT * FROM v$sys_time_model;
Select three correct interpretations of the time model statistics. (Choose three.)
A. DB time includes the wait time of all the nonidle and idle user sessions.
B. SQL execute elapsed time includes the time spent in performing fetches of query results.
C. DB CPU includes the CPU time spent on database user-level calls and background CPU time.
D. SQL execute elapsed time includes components of the hard parse elapsed time like bind elapsed time.
E. DB time includes the connection management call elapsed time excluding the background process
time.

NO.4 You are working on a development database that was upgraded to Oracle Database 11g from Oracle
Database 9i. An ADDM finding in this database says that the shared pool is inadequately sized, as shown
in the Exhibit.
You diagnosed that this is due to different kinds of workloads and this occurs only during peak hours. You
tried to resize this by shrinking the database buffer cache but that caused inadequate buffer cache
problems. The following are the related parameter settings:
SQL> show parameter sga
NAME TYPE VALUE
------------------------------ --------------- -----------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 300M
sga_target big integer 0
SQL> show parameter target
NAME TYPE VALUE
------------------------------ --------------- -----------------
.....
fast_start_mttr_target integer 0
memory_max_target big integer 0
memory_target big integer 0
pga_aggregate_target big integer 100M
sga_target big integer 0
You want to balance the memory between the System Global Area (SGA) components within SGA
without affecting the size of the Program Global Area (PGA).
Which action would solve this problem?
A. Set the SGA_TARGET parameter to 300M.
B. Set the SGA_MAX_SIZE parameter to 400M.
C. Set the MEMORY_TARGET parameter to 100M.
D. Set the MEMORY_MAX_TARGET parameter to 300M.

NO.5 You work as a DBA for a company and you have the responsibility of managing one of its online
transaction processing (OLTP) systems. The database encountered performance-related problems and
you generated an Automatic Workload Repository (AWR) report to investigate it further.
View the Exhibits and examine the AWR report.
What could be the problem in this database?
A.Java pool is not configured.
B.The CPU in the system is slow.
C.The shared pool size is inadequate.
D.The database buffer cache is inadequate.
E.The OPEN_CURSORS parameter is set to a small value.

NO.7 A user in a session executed the following SQL statement to set the optimizer mode:
ALTER SESSION SET OPTIMIZER_MODE = ALL_ROWS
What impact would it have on the goal of the optimizer for that session? (Choose all that apply.)
A. Statement level OPTIMIZER_MODE hints take precedence over the session-level setting.
B. The OPTIMIZER_MODE parameter set at instance level takes precedence over the session-level
value.
C. The optimizer uses a cost-based approach, regardless of the presence of statistics; it optimizes with a
goal of best response time.
D. The optimizer uses a cost-based approach for all SQL statements in the session, regardless of the
presence of statistics; it optimizes with a goal of best throughput.
