Oracle Database 19c Performance and Tuning Management Sample Questions (Q38-Q43):

NEW QUESTION # 38
Examine this statement and output:

Which two situations can trigger this error?

A. The syntax is incomplete.
B. The instance is unable to access the capture directory.
C. The user lacks the required privileges to execute the DBMS WORKLOAD CAPTURE package or the directory.
D. There is a file in the capture directory.
E. The capture directory is part of the root file system.

Answer: B,C

Explanation:
The ORA-15505 error indicates that the instance encountered errors while trying to access the specified directory. This could be due to:
A: Insufficient privileges: The user attempting to start the workload capture might not have the required permissions to execute the DBMS_WORKLOAD_CAPTURE package or to read/write to the directory specified.
E: Accessibility: The database instance may not be able to access the directory due to issues such as incorrect directory path, directory does not exist, permission issues at the OS level, or the directory being on a file system that's not accessible to the database instance.

NEW QUESTION # 39
Which two statements are true about disabling Automatic Shared Memory Management (ASMM)?

A. All SGA components retain their current sizes at the time of disabling.
B. The SGA size remains unaffected after disabling ASMM.
C. It requires a database instance restart to take effect.
D. All auto-tuned SGA components are reset to their original user-defined values.
E. Both SGA_TARGET and SGA_MAX_SIZE must be set to zero.
F. All SGA components excluding fixed SGA and other internal allocations are readjusted immediately after disabling ASMM.

Answer: A,B

Explanation:
When ASMM is disabled, the sizes of the automatically managed SGA components remain at their current values. ASMM is controlled by the SGA_TARGET parameter. If SGA_TARGET is set to a non-zero value, ASMM is enabled and Oracle will automatically manage the sizes of the various SGA components. When ASMM is disabled, by setting SGA_TARGET to zero, the SGA components that were automatically sized will retain their current sizes rather than being reset to their original user-defined values. The overall size of the SGA remains the same unless manually changed by modifying individual component sizes or SGA_MAX_SIZE.

NEW QUESTION # 41
Examine this AWRreport excerpt:

You must reduce the impact of database I/O, without increasing buffer cache size and without modifying the SQL statements.
Which compression option satisfies this requirement?

A. COLUMN STORE COMPRESS FOR QUERY HIGH
B. STORE COMPRESS
C. ROW STORE COMPRESS ADVANCED
D. MN STORE COMPRESS FOR QUERY LOW

Answer: C

Explanation:
To reduce the impact of database I/O without increasing the size of the buffer cache and without modifying SQL statements, you can use table compression. Among the given options,ROW STORE COMPRESS ADVANCEDis the most suitable form of table compression to satisfy this requirement.
Advanced row compression (ROW STORE COMPRESS ADVANCED) is designed to work well with all supported types of data, whether it's OLTP or data warehouse environments. It offers a higher level of compression than basic table compression (ROW STORE COMPRESS BASIC)without significant overhead during DML operations. This feature can help reduce the amount of I/O required to retrieve data by storing it more efficiently on disk.

NEW QUESTION # 42
Which two statements are true about cursor sharing?

A. Adaptive Cursor Sharing guarantees that a suboptimal plan will never be used on any execution of a SQL statement.
B. Setting Cursor_sharing to FORCE can result in a plan that is suboptimal for the majority of values bound to a bind variable when executing a cursor with one or more bind variables.
C. Adaptive Cursor Sharing requires histograms on filtered columns, used in equality predicates, to allow different execution plans to be generated for statements whose bound values would normally generate different plans at hard parse time.
D. Setting cursor_sharing to EXACT prevents Adaptive Cursor Sharing from being used.
E. Setting optimizer_capture_sql_plan_baselines to TRUE loads all adaptive plans for the same statement into the cursor cache.

Answer: B,D

Explanation:
A: WhenCursor_sharingis set toFORCE, Oracle tries to avoid hard parses by replacing literals in SQL statements with bind variables, even if the original statement didn't include bind variables. This can lead to the use of a single execution plan for multiple executions of a statement with different literal values, which might not be optimal for all executions.
D: Settingcursor_sharingtoEXACTensures that SQL statements must match exactly for them to share a cursor. This setting prevents the use of Adaptive Cursor Sharing (ACS) since ACS relies on the ability to share cursors among similar statements that differ only in their literal values. WithEXACT, there's no cursor sharing for statements with different literals, hence no opportunity for ACS to operate.
