Oracle Database 10g R2: Administering RAC Sample Questions:

1. You decide to implement a Dataguard configuration for your RAC installation to support your disaster recovery architecture. There are two instances on the primary and two on the physical standby. Which are the two appropriate settings for the DG_BROKER_CONFIG_FILE1 and DG_BROKER_CONFIG_FILE2 initialization parameters? (Choose two.)

A) DG_BROKER_CONFIG_FILE1 set to a location shared between each standby database instance and DG_BROKER_CONFIG_FILE2 set to a different location shared between each standby database instance on the standby database cluster.
B) DG_BROKER_CONFIG_FILE1 set to a nonshared location for each secondary database instance and DG_BROKER_CONFIG_FILE2 set to a shared location for each secondary database instance on the secondary database cluster.
C) DG_BROKER_CONFIG_FILE2 set to the same shared location for the second instance of both the primary and the standby databases.
D) DG_BROKER_CONFIG_FILE1 set to the same shared location shared between the first instance of both the primary and the standby databases.
E) DG_BROKER_CONFIG_FILE1 set to a nonshared location for each primary database instance and DG_BROKER_CONFIG_FILE2 set to a shared location for each primary database instance on the primary database cluster.
F) DG_BROKER_CONFIG_FILE1 set to a location shared between each primary database instance and DG_BROKER_CONFIG_FILE2 set to a different location shared between each primary database instance on the primary database cluster.

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

3. After applying a patch to the network device drivers in your operating system, you verify using CRS_STAT-T that everything runs normally. View Exhibitl for the CRS_STAT-T output.
After your coffee break, customers begin complaining about the performance of your Oracle Real Application Clusters database. Suddenly, the response time has increased and establishing new connections is slower than it used to be. You run CRS_STAT-T again to check if there is a problem.
Based on Exhibit2, what is your conclusion, and what would you do to correct this?

A) You cannot tell what the problem is based on Exhibit2, so you cannot fix this.
B) There is no problem, so nothing needs to be corrected.
C) The second node in your cluster is down and, therefore, CRS has relocated the VIP from the second node to the first node. After you fix the problem on the second node, you have to relocate the relocated VIP back to its original node using the SRVCTL command.
D) The second node in your cluster is down and, therefore, CRS has relocated the VIP from the second node to the first node. After you fix the second node, CRS would relocate the relocated VIP back to its original node.
E) Somebody relocated the VIP from the second node to the first node for an unknown reason. You just have to relocate it back.

4. View the Exhibit and examine the diagram of the RAC environment implemented on a Linux platform in your company.
As a senior DBA, you have been assigned the task to implement ASM in this environment. You configured the raw devices that you plan to add to the ASM disk group.
How would you create an ASM instance on each node? (Choose all that apply.)

A) by using Oracle Universal Installer (OUI) on any one of the nodes
B) by using the oracleasm configure command on both the nodes
C) by using the oracleasm configure command on any of the nodes
D) by using the ASMCMD command-line utility on both the nodes
E) by using DBCA on all nodes
F) by using Database Configuration Assistant (DBCA) on any one of the nodes

5. View the Exhibit, which displays a portion of an ADDM report from a RAC database. Which three statements are true? (Choose three.)

A) The ADDM report output reveals a "hot block" condition.
B) The SQL statement with the ID dqsu2hwys8rcf was executed 40000 times
C) The Findings Path section indicates that the Cluster wait class is consuming a significant proportion of the database time.
D) A LOCK TABLE statement is causing excessive inter-instance messaging.
