You enabled Automatic Shared Memory Management. The initialization parameters are set as shown below:
SGA_TARGET= 10GB
SGA_MAX_SIZE = 14GB
STREAMS_POOL_SIZE = 1GB
SHARED_POOL_SIZE = 3GB
Which two statements are correct in this scenario? (Choose two.)

A.    A maximum of 3 GB can be allocated to shared pool.
B.    The value for SGA_TARGET can be increased up to a maximum of 14 GB.
C.    A total of 14 GB memory will be allocated to the automatically tuned memory components.
D.    Increasing the value for SGA_TARGET will automatically increase the memory allocated for STREAMS_POOL_SIZE.
E.    Increasing the value for SGA_TARGET to 12 GB will automatically increase the memory allocated to autotuned parameters.
F.    Reducing the value for SGA_TARGET to 9 GB will automatically decrease the memory allocated to shared pool from 3 GB to 2 GB.

Answer: BE

QUESTION 85
You executed the following command in Recovery Manager (RMAN) against your Oracle 10g database:
RAMN>REPORT NEED BACKUP days 3; What would be the output of this command?

A.    a list of files that require a backup within three days
B.    a list of files that have not been backed up for three days

Answer: B

QUESTION 86
Your database operates in ARCHIVELOG mode. The redo log files are not multiplexed and one of the online redo logs is missing. The missing redo log sequence, 230, is not archived and it contained information from 10:35 a.m.onwards.
The current time is 11:00 a.m. Because of a disk crash, you executed the following command to perform an incomplete recovery:
RMAN> RUN {
2> SET UNIT SEQUENCE 230 THREAD 1;
3> ALTER DATABASE MOUNT;
4> RESTORE DATABASE;
5> RECOVER DATABASE;
6> ALTER DATABASE OPEN RESTLOGS;
7> };
With reference to this scenario, which statement is true?

A.    RMAN recovers up to log sequence 230, but not including 230.
B.    RMAN returns an error because the log sequence number mentioned in the command should be 229.
C.    RMAN returns an error because the log sequence number mentioned in the command may never be missing.
D.    RMAN recovers up to and including log sequence 229 but then returns an error because log sequence 230 is missing.

Answer: A

QUESTION 87
In your database, all the tablespaces are locally managed. You started Recovery Manager (RMAN) using recovery catalog and restored the control file by using the following command:

A.    shut down and restart the instance
B.    add new temp files to the temporary tablespaces after recovery
C.    perform a media recovery and open the database with the RESETLOGS option
D.    perform a media recovery and bring the database to NOARCHIVELOG mode

Answer: BC
