Oracle 1z0-042: Oracle Database 10g: Administration I

#101. Exhibit:

Which statement causes more undo generation?

#102. Where do you find information about a missing redo log file?

#103. You are using flat files as the data source for one of your data warehousing applications. You plan to move the data from the flat file structures to an Oracle database to optimize the application performance. In your database you have clustered tables.
While migrating the data, you want to have minimal impact on the database performance and optimize the data load operation. Which method would you use to load data into Oracle database?

#104. The database users are connecting to the PROD database from different applications, thereby degrading the database performance. The senior database administrator suspects the large number of concurrent connections to be the reason for low performance and asks you to restrict the number concurrent connections per database user to one.
Which action would you take to achieve this objective?

#105. What advantage would you get if you increase the length of time during which the undo information would be stored in the database?

#106. One of the users in the PROD database, Adams, complains that his update on the table, TRANS, is taking an unusually long time to complete. You find that the table gets locked by another database user before Adams starts his transactions, and you are unable to contact the user holding the table lock. As Adams is updating some crucial rows in the table, he should get the highest priority.
Which method would you use to overcome this problem?

#107. Exhibit:

Which two options are used to enable the connect-time failover feature? (Choose two.)

#108. You have created a baseline metric, DISK_IO_BL, for the disk I/O metrics in your PROD database and you have been getting notifications whenever the database performance degrades. You optimize the database I/O to gain the performance and you decide to remove the baseline metrics. Which method would you use to remove the DISK_IO_BL baseline metrics?

#109. Exhibit.

Your Oracle 10g database has 6 tablespaces in which:
-TEMP is the default temporary tablespace
- UNDOTBS1 is the default undo tablespace
- USERS is the default permanent tablespace
In this database, which three tablespaces can be made offline? (Choose three.)

#110. A user complains that he gets the following error message repeatedly after executing some SQL statements. The error message forces the user to log off from and log on to the database to continue his work.
ORA-02392: exceeded session limit on CPU usage, you are being logged off Which action would you take to increase the session limit on CPU usage?
