Oracle Database 10g R2: Administering RAC Sample Questions:

1. After a power failure, you noticed that one of your cluster database instances did not start automatically, whereas all other instances came up successfully. What would you do to determine the precise cause for the instance startup failure? (Choose three.)

A) Check for OCR corruptions by using the OCRCHECK command.
B) Check the alert.log file that belongs to the instance that did not start.
C) Enable extra debugging in the Oracle Clusterware software by using the CRSCTL command.
D) Reboot the node where the failing instance resides to check if the problem is persistent.
E) Check the alert.log file that belongs to the Oracle Clusterware software.
F) Check the resource state by using the CRS_STAT command.
G) Check if the Oracle Clusterware is functional by using the CRSCTL command.

2. 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) 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.
B) 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.
C) Tune SQL for the OLTP and DSS service programs because they may benefit from SQL tuning.
D) The BATCH 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.

3. Your company has a combination of high availability and scalability requirements that need to be addressed, and RAC has been discussed as a solution. There are a mix of "off-the-shelf software products and homegrown applications currently in use in your environment that run on single-instance Oracle databases. You have been asked by the IT director to provide an impact analysis report to help assess the impact on applications when migrating to RAC. Which three are among the areas that should be examined for performance impact and application functionality impact or for both? (Choose three.)

A) client/server type applications that use application local context variables
B) applications that use large parallel full table scans
C) three-tier applications that use application global context variables
D) applications that use SQL profiles created by the ATO optimizer in the SQL Tuning Advisor
E) applications that truncate tables in a data warehouse process
F) applications that access small tables using the same index occasionally

4. You decide to implement a Data Guard configuration to support a disaster recovery plan for your RAC database. Your primary database has all shared files and the flash recovery area is stored on ASM disk groups. Which three options exist for storing the data guard broker configuration files at the primary location? (Choose three.)

A) can be stored on shared Raw Devices
B) must be in the same shared ASM disk group as the Flash Recovery Area if the broker configuration files are stored in ASM disk groups.
C) must be stored on Oracle Cluster File System if a cluster file system is used
D) can be in any shared ASM disk group
E) must be in the same shared ASM disk group as the database data files if the broker configuration files are stored in ASM disk groups
F) may be stored on any supported cluster file system if a cluster file system is used

5. You observe a high number of gc current failure on your RAC system. What could be causing this issue?

A) You are not using the correct private interconnect.
B) Too much parsing is occurring on your system.
C) There is too much contention on the High Water Mark enqueue of your tables.
D) Too much manual locking is occurring.
