Oracle Database 19c Performance and Tuning Management Sample Questions (Q15-Q20):

NEW QUESTION # 15
Which application lifecycle phase could be managed reactively?

  • A. Testing
  • B. Production
  • C. Design and development
  • D. Deployment
  • E. Upgrade or migration

Answer: B

Explanation:
The production phase of the application lifecycle is often managed reactively. While proactive measures and performance tuning are essential, unforeseen issues can arise in production that require immediate attention and resolution. Reactive management involves monitoring performance and responding to issues as they occur, ensuring the application maintains acceptable performance levels for end-users.

NEW QUESTION # 16
Which two statements are true about the use and monitoring of Buffer Cache Hit ratios and their value in tuning Database I/O performance?

  • A. A 60% cache hit ratio can be observed for database instances which have very good I/O performance.
  • B. The buffer cache advisory view v$db_cache_advice provides advice on cache hit ratios appropriate for the instance workload.
  • C. The performance of workloads that primarily generate full table scans and fast full index scans are always affected by the cache hit ratio.
  • D. A 99% cache hit ratio can be observed for database instances which have very poor I/O performance.
  • E. Both the RECYCLE and KEEP buffer caches should always have a very high cache hit ratio.

Answer: B,D


NEW QUESTION # 17
Which two actions can cause invalidation or loss of one or more results in the SQL Query Result Cache?

  • A. A request was made by the RCBG background process in a physical standby database that is opened read only and whose primary has a result cache.
  • B. result_cache_max_size is set dynamically to 0.
  • C. Decreasing the value set for RESULT_CACHE_REMOTE_EXPIRATION.
  • D. One or more results were aged out of the result cache.
  • E. A request was made by the RCBG background of a non-RAC database.

Answer: B,D

Explanation:
The SQL Query Result Cache stores the results of queries and PL/SQL function calls for reuse. However, entries in the result cache can be invalidated or lost under certain conditions:
A: Results can be aged out of the cache when the cache becomes full and new results need to be stored. This process ensures that the cache does not exceed its allocated memory and that it contains the most recently used entries.
B: Setting theRESULT_CACHE_MAX_SIZEparameter to 0 will effectively disable the result cache and all cached results will be lost, as Oracle will no longer allocate any memory to the result cache.

NEW QUESTION # 18
Examine these commands, which execute successfully:

Which statement is true?

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

Answer: D

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 # 19
Examine this statement and output:

Which three statements are true?

  • A. Session 9857 is not waiting.
  • B. Session 8779 may be waiting for a user or application response.
  • C. Session 8779 may be waiting due to a network problem.
  • D. Both 9822 and 8779 sessions are waiting for operating system resources.
  • E. Session 9857 waited 1354 seconds for another process, which was also waiting for a transaction to end.
  • F. Session 9822 will always stop waiting if the session that owns the TX enqueue issues a COMMIT statement as session 9822 is the first session in the transaction queue.

Answer: B,C,F

Explanation:
For this SQL statement and output, we can analyze theEVENTcolumn to understand the type of wait:
B: The event "SQL*Net message from client" typically indicates that the session is waiting for a response from the client. This can be due to a network issue, user response, or an application processing delay.
E: The event "SQL*Net message from client" also implies that the session is idle waiting for the client (a user or an application) to send a request to the server. This event usually indicates that the session is not actively working but is instead waiting for the next command.
F: The wait event "enq: TX - row lock contention" suggests that session 9822 is waiting for a row-level lock held by another session. If the holding session issues a COMMIT or ROLLBACK, the lock will be released, and session 9822 will stop waiting. Since this session is experiencing row lock contention, it implies it's waiting for a specific transaction to complete.
