1. You observe that a database performance has degraded over a period of time. While investigating the
reason, you find that the size of the database buffer cache is not large enough to cache all the needed data
blocks.
Which advisory component would you refer to, in order to determine that required size of the database
buffer cache?
A. Memory Advisor
B. Segment Advisor
C. SQL Tuning Advisor
D. SQL Access Advisor
E. Automatic Database Diagnostic Monitor (ADDM)
Answer: A
2. In your production database, the total waits and the time waited for log file parallel write are significantly
high. While investigating the reason, you find that there are three redo log groups with two members in
each group, and all redo log members are places on a single physical disk.
What action would you take to minimize the waits?
A. start the log writer slave processes
B. increase the number of redo log files
C. increase the size of the redo log buffer
D. place the redo log files on the different disks
E. increase the number of log writer processes
Answer: D
3. One of the tablespace is read-only in your database. The loss of all control files forced you to recreate the
control file.
Which operation do you need to perform after re-creating the control file and opening the database?
A. drop and re-create the read-only tablespaces
B. rename the read-only data files to their correct file names
C. change the tablespace status from read/write to read-only
D. re-create the read-only tablespace because it is automatically removed
Answer: B
4. You have set some of the initialization parameters as:
DB_BLOCK_SIZE = 8KB
SGA_MAX_SIZE = 2GB
SGA_TARGET = 0
SHARED_POOL_SIZE = 120MB
DB_CACHE_SIZE = 896MB
STREAM_POOL_SIZE = 0
LARGE_POOL_SIZE = 110 MB
Which two statements are correct? (Choose two.)
You cannot set a value for the DB_8K_CACHE_SIZE parameter.
A. You cannot set a value for the DB_8K_CACHE_SIZE parameter.
B. If you increase the size of the large pool to 120 MB, then the memory allocated to the shared poll will be
reduced to 110 MB.
C. If the value for SGA_TARGET is changed to 1 GB and SHARED_POOL_SIZE is set to 120 MB, then
memory cannot be taken from the shared pool, even if the shared pool has free space available.
D. If an application attempts to allocate more than 120 MB from the shared pool and free space is available
in the buffer pool, then the free space from the buffer pool is allocated to the shared pool.
