第1题:
While designing the database for one of your online transaction processing (OLTP) applications, you want to achieve the following: a) high availability of data b) faster primary key access to the table data c) compact storage for the table Which type of tables would you use to achieve these objectives?()
第2题:
You are maintaining your OLTP database in Oracle10g. You are performing the Flashback Transaction Query to find the undo SQL statements that can be used to undo the changes made to the database in the specific time period. Which pseudocolumn will you use to perform the Flashback Transaction Query?()
第3题:
In one of your online transaction processing (OLTP) applications, most users frequently modify the values, including the key values, of the application tables. Some users generate application reports by using multiple application tables. What is the best table structure that you can use to gain optimal performance?()
第4题:
In one of your online transaction processing (OLTP) applications, users are manipulating and querying a database table simultaneously. From the Segment Advisor, you find that one of the tables is highly fragmented and you want to shrink the table immediately without affecting the currently active queries. Which option would you use with the ALTER TABLE command to achieve this objective?()
第5题:
DBA_PENDING_TRANSACTIONS
DBA_AUDIT_STATEMENT
V$FLASHBACK_DATABASE_STATS
FLASHBACK_TRANSACTION_QUERY
第6题:
Use the CREATE DATABASE .. command to create the database with Oracle-managed files.
Use the Database Configuration Assistant (DBCA) to create the database with Oracle-managed files.
Use Enterprise Manager to create a new database with the Online Transaction Processing (OLTP) option.
Use Database Configuration Assistant (DBCA) to create the database with Transaction Processing template.
Use the CREATE DATABASE .. command to create the database with Automatic Storage Management (ASM) file system.

第13题:
Your database supports a DSS workload that involves the execution of complex queries: Currently, the library cache contains the ideal workload for analysis. You want to analyze some of the queries for an application that are cached in the library cache. What must you do to receive recommendations about the efficient use of indexes and materialized views to improve query performance?()
第14题:
You want to create a new optimized database for your transactional production environment to be used by a financial application. While creating the database, you want the Oracle software to take care of all basic settings to optimize the database performance. Which method would you use to achieve this objective?()
第15题:
Your database supports an online transaction processing (OLTP) application. The application is undergoing some major schema changes, such as addition of new indexes and materialized views. You want to check the impact of these changes on workload performance. What should you use to achieve this?()
第16题:
At 10:30 A.M., you ran a batch job by mistake, which executed a transaction in the database. The transaction identifier of the transaction that made to the changes in the database is 0500A00627B000. At 11:10 A.M., you stopped the batch job. Now, you want to identify the changes made to the database tables by the batch job. Which view will you query?()
