View the Exhibit and examine the Resource Manager settings for the groups at different levels. Which two effects would be the result of this setting? (Choose two.) Exhibit:
A. The members of LOW_GROUP would get more priority than those of OTHER_GROUPS.
B. The members of SYS_GROUP would get most of the CPU allocation at level 1.
C. The members of LOW_GROUP would get most of the CPU allocation because it has CPU allocation at two different levels.
D. The members of LOW_GROUP would get no CPU allocation at level1 if the members of OTHER_GROUPS are using all the CPU at level 2.
E. The members of SYS_GROUP would get no CPU allocation at level 1 if the members of OTHER_GROUPS are using all the CPU at level 2.
The current time zone for one of the user sessions is set to the database local time zone. For one application, the user session requires the time zone to be set to the local operating system time zone without affecting other user sessions. Which two solutions could the user implement to achieve this objective? (Choose two.)
A. use the ALTER SYSTEM command to change the time zone
B. use the ALTER SESSION command to change the time zone
C. use the ALTER DATABASE command to change the time zone
D. set the value for the operating system variable ORA_SDTZ on the client machine
E. set the value for the operating system variable ORA_SDTZ on the database server machine
You work as a database administrator at certkiller.com. Your database is open and running in ARCHIVELOG mode. You take RMAN full backups every Sunday night. On Monday morning, while querying the user1.employees table, you receive the following error message:
01578: ORACLE data block corrupted (file # 5, block # 51)
ORA-01110: data file 5:
You need to rectify the corruption while ensuring the following:
The data file should remain online.
The mean time to recover (MTTR) should be minimal.
You are not using a backup control file and all the archived logs are accessible. Which option would you choose?
A. flash back the corrupted blocks
B. use the DBMS_REPAIR package
C. use the RMAN TSPITR command
D. use the RMAN BLOCKRECOVER command
E. use the RESTORE DATABASEand RECOVER DATABASE commands
F. investigate the time at which the corruption occurred and perform a point-in-time recovery
You are working on an Oracle Database 10g database. You enabled the Flashback Database feature. Which two statements regarding flashback logs are true? (Choose two.)
A. Flashback logs are not archived.
B. Flashback logs are maintained in redo log files.
C. Flashback logs are maintained in the Flash Recovery Area.
D. Flashback logs are used to maintain Flashback Database related errors.
E. Flashback logs need to be cleared manually after you disable Flashback Database.
You executed the following query:
SELECT operation, undo_sql, table_name
Which statement is correct regarding the query output?
A. It would return information regarding only the last committed transaction.
B. It would return only the active transactions in all the undo segments in the database.
C. It would return only the committed transactions in all the undo segments in the database.
D. It would return both active and committed transactions in all the undo segments in the database.
E. It would return information regarding the transactions that began and were committed in the last 30 minutes.
Consider the following configuration:
/devices/D1 is a member of disk group dgroupA.
/devices/D2 is a member of disk group dgroupA.
/devices/D3 is a member of disk group dgroupA.
You plan to add a new disk,/devices/D4 to the disk group dgroupA.
You execute the following command:
SQL> ALTER DISKGROUP dgroupA ADD DISK ‘/devices/D*’;
Which task would be accomplished by the command?
A. The command adds the new disk, D4, to the disk group.
B. The command would result in an error because the is no disk by the name "’/devices/D*’"
C. The command will be ignored because disks starting with "D" are already members of the disk group.
D. The command would result in an error because no wildcard characters can be used in the disk name.
E. The command first detaches all the member disks starting with "D", and the reattaches them including
the new disk.
You work as a database administrator at certkiller.com. In your production database there is a job, CALC_STAT, which has been scheduled to run every Friday at 5.00 p.m.CALC_STAT updates the optimizer statistics for the objects owned by the APPS schema. You want the task to be generic, thereby allowing users to modify the attributes of the task at run time without affecting the original task. Which component of Oracle Scheduler must you define to achieve this?
C. Job class
D. Window group
Immediately after adding a new disk to or removing an existing disk from an Automatic Storage Management (ASM) instance, you find that the performance of the database decreases initially, until the addition or removal process is completed. Performance then gradually returns to normal levels. Which two activities could you perform to maintain a consistent performance of the database while adding or removing disks? (Choose two.)
A. increase the number of checkpoint processes
B. define the POWER option while adding or removing the disks
C. increase the number of DBWR processes by setting up a higher value for DB_WRITER_PROCESSES
D. increase the number of slave database writer processes by setting up a higher value for DBWR_IO_SLAVES
E. increase the number of ASM Rebalance processes by setting up a higher value for ASM_POWER_LIMIT during the disk addition or removal
The current time is 12:00 noon. You want to recover the USERS tablespace from a failure that occurred at 11:50 a.m.You discover that the only member of an unarchived redo log group containing information from 11:40 a.m. onwards is corrupt.
With reference to this scenario, if you are not using Recovery Manager (RMAN), which recovery method would you use?
A. time-based recovery
B. log sequence recovery
C. cancel-based recovery
D. change-based recovery
