Oracle Database 19c Performance and Tuning Management Sample Questions (Q17-Q22):

NEW QUESTION # 17
Examine this statement and output:

Which two situations can trigger this error?

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

Answer: A,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 # 18
Which three statements are true about using the in Memory (IM) column store?

A. It does not improve performance for queries using cached results of function evaluations on columns from the same table.
B. It improves performance for queries joining several tables using bloom filter joins.
C. It can improve OLTP workload performance by avoiding the use of indexes.
D. It does not improve performance for queries using user-defined virtual column results.
E. It does not improve performance for queries that use join groups on columns from different tables.
F. It does not require all database data to fit in memory to improve query performance.

Answer: B,C,F

Explanation:
The Oracle In-Memory (IM) column store feature enhances the performance of databases by providing a fast columnar storage format for analytical workloads while also potentially benefiting OLTP workloads.
* C (True):It can improve OLTP workload performance by providing a faster access path for full table scans and reducing the need for indexes in certain scenarios, as the In-Memory store allows for efficient in-memory scans.
* E (True):The In-Memory column store does not require all database data to fit in memory. It can be used selectively for performance-critical tables or partitions, and Oracle Database will manage the population and eviction of data as needed.
* F (True):In-Memory column store can significantly improve performance for queries joining several tables, especially when bloom filters are used, as they are highly efficient with the columnar format for large scans and join processing.
The other options provided are not correct in the context of the In-Memory column store:
* A (False):While In-Memory column store is designed for analytical queries rather than caching results of function evaluations, it does not specifically avoid improving performance for queries using cached results of function evaluations.
* B (False):In-Memory column store can improve the performance of queries that use join groups, which can be used to optimize joins on columns from different tables.
* D (False):In-Memory column store can improve the performance of queries using expressions, including user-defined virtual columns, because it supports expression statistics which help in
* optimizing such queries.

NEW QUESTION # 19
Examine these commands, which execute successfully:

Which statement is true?

A. AWR- snapshots in all pluggable databases will be purgedautomatically after every 60 mins.
B. AWR snapshots can be purged manually in pluggable databases.
C. AD DM is enabled for all pluggable databases.
D. ADDM, AWR, and ASH reports can be purged automatically.

Answer: B

Explanation:
TheDBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGSprocedure allows setting attributes related to AWR snapshots. While the interval setting controls the frequency of snapshot generation, purging them is a separate process that can be managed either automatically (with retention settings) or manually.References:

NEW QUESTION # 20
Users complain about slowness and session interruptions. Additional checks reveal the following error in the application log:

Which file has additional information about this error?

A. ASH report
B. Session trace file SQL trace file automatically generated by the error
C. SQL trace file automatically generated by the error
D. Alert log

Answer: D

Explanation:
When an ORA-00060 deadlock error occurs, detailed information about the error and the deadlock graph are dumped into the alert log. This log contains a trace file name that you can use to find additional detailed information about the sessions involved in the deadlock and the SQL statements they were executing.

NEW QUESTION # 21
You execute the following:
EXECUTE DBMS_AuTO_TASK_ADMIN.DISABLE;
Which advisor remains enabled?

A. Automatic SQL Tuning
B. Automatic Optimizer Statistics Collection
C. Automatic Segment Advisor
D. SQL Plan Management Evolve Advisor
E. Optimizer Statistics Advisor

Answer: B

Explanation:
When you executeDBMS_AUTO_TASK_ADMIN.DISABLE, it disables all automated maintenance tasks related to the Auto Task framework. This includes tasks such as the Automatic SQL Tuning Advisor, Automatic Segment Advisor, and others. However, the Automatic Optimizer Statistics Collection (D) remains enabled as it is not part of the Auto Task framework. The gathering of optimizer statistics is controlled separately and is a critical part of the database's self-tuning mechanism to ensure the optimizer has up-to-date information about the data distribution within tables and indexes.
