Which three types of statistics are captured by statspack with snap level 6?

Show Suggested Answer Hide Answer
Suggested Answer: A, E, F

Statspack is a performance diagnostic tool provided by Oracle prior to the introduction of the Automatic Workload Repository (AWR). At snap level 6, Statspack captures the following types of statistics:

A (Correct): Parent and child latches are captured. Latch statistics provide information about contention for latches, which are low-level serialization mechanisms used by Oracle.

E (Correct): Enqueue statistics, which provide information on the waits for locks that manage the concurrency between users.

F (Correct): Segment-level statistics, which provide detailed information on database segments such as tables, indexes, etc., to identify I/O and contention issues.

C (Incorrect): While optimizer execution plans are an essential aspect of performance tuning, detailed execution plan capture is not part of the Statspack report at level 6.

D (Incorrect): Plan usage data refers to how frequently a plan is being used, which is more associated with AWR and not typically captured in Statspack reports.

Wait, wait, wait... did they really just ask about 'parent and child latches' twice? I think someone needs to go back to Oracle Fundamentals 101.

Ha! This question is a real head-scratcher. I'm going to go with the classic 'all of the above' approach. Can't go wrong with that, right?

Hmm, I'm not so sure. I was thinking C, D, and F might be the correct options - optimizer execution plans, plan usage data, and segment-level statistics.

I'm not sure, but I think it could be A, B, and E - parent and child latches and enqueue statistics.

I'm not sure about the third one, but I know for sure it includes parent and child latches.

I think the answer is A, B, and E. Parent and child latches, and enqueue statistics are definitely captured by statspack at level 6.
