Oracle Database 10g R2: Administering RAC Sample Questions:

1. Several steps must be followed to successfully add a new node to your cluster database. Assuming that a UNIX platform is used, which of the three steps below are correct? (Choose three.)

A) Add instances using OUI.
B) Reconfigure listeners for the new node with netca.
C) Add the node to the cluster using the addnode.sh script run from ORA_CRS_HOME.
D) Add the RAC software to the new node using addnode.sh from ORA_CRS_HOM
E) Configure the OS and hardware for the new node.

2. When do you get the first notification after you execute the following command on instance
RDBA1?
execDBMS_SERVER_ALERT.SET_THRESHOLD(-
METRICSJD => dbms_server_alert.elapsed_time_per_call,
WARNINGJDPERATOR => dbms_server_alert.operator_ge,
WARNING_VALUE => 500000',
CRITICAL_OPERATOR => dbms_server_alert.operator_ge,
CRITICAL_VALUE => 750000',
OBSERVATION_PERIOD => 15,
CONSECUTIVEJDCCURRENCES => 3,
INSTANCE_NAME => 'RDBA1',
OBJECT_TYPE => dbms_server_alert.object_type_service,
OBJECT_NAME =>'ERP");

A) when the average elapsed time per call for the ERP service over a 15-minute period exceeds
0.5 seconds three consecutive times
B) when the average elapsed time per call for the ERP service over a 45-minute period exceeds
0.75 seconds
C) when the average elapsed time per call for the ERP service over a 15-minute period exceeds
0.75 seconds three consecutive times
D) when the average elapsed time per call for the ERP service over a 45-minute period exceeds
0.5 seconds

3. The following are some of the tasks that are performed during a RAC implementation: 1) Setting the Oracle database-related environment variables 2) Creating a password file 3) Installing Management Service and Management Agent 4) Creating and editing the Raw Device Mapping file 5) Creating an ASM instance 6) Creating the Oracle Cluster Registry (OCR) file 7) Implementing the Transparent Application Failover (TAF) policy 8) Creating database services Identify the tasks that can be performed using the DBCA, or performed by the DBCA, during database creation in the RAC implementation.

A) All the tasks
B) 1,3,4,6
C) 2,3,5,7,8
D) 1,2,3,5,6,8
E) 2,3,4,6,7

4. You have a four-node cluster with instances RDBD1, RDBD2, RDBD3, and RDBD4. While evaluating statspack reports, you find nq: TX- index contention on page one under the category op 5 Timed Events.
Further study finds an unusually high number of c buffer busy waits in the Wait Events section. Checking the Instance Activity Stats section, you see an unusually high value for eaf Node Splits. Using v$segment_statistics, you identify that the top segment with c buffer busy waits is the index prooducts_pk, which obtains the primary key from a sequence. You wish to present alternative solutions to the team to help reduce contention.
Which three actions would you recommend to reduce the overheads? (Choose three.

A) Set _lm_msg_batch_size to a higher value.
B) Increase the sequence cache size if retaining the sequence.
C) Re-create the table using a natural key instead of a surrogate key.
D) Encourage shorter transactions.
E) Set fast_start_mttr_target to a higher value.
F) Re-create the index as a global hash partitioned index.

5. 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.)

A) Tune SQL for the OLTP and DSS service programs because they may benefit from SQL tuning.
B) The BATCH service programs may scale well and could benefit from adding new database instances on either node 5 or 6, or on both.
C) The OLTP and DSS service programs may scale well and could benefit from adding new database instances on one or both of nodes 5 and 6, and by adding more nodes the SQL for BATCH service programs would perform better due to more CPU power.
D) The OLTP and DSS service programs may scale well and could benefit from adding new database instances on either node 5 or 6, or on both.
E) Tune SQL from the BATCH service programs because they may benefit from SQL tuning.
