Which THREE statements are TRUE about Global Sequences when connected to a physical standby database with Real-Time Query enabled?

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

Global Sequences are Oracle sequences that generate unique values across multiple instances in an Oracle RAC or a Data Guard configuration. Regarding their behavior and performance when connected to a physical standby database with Real-Time Query enabled:

A: The usage of Global Sequences can indeed have a performance impact on the primary database due to the need to generate unique values that are consistent across both primary and standby databases.

D: The performance impact on the physical standby database may occur if the CACHE size is too small. This is because the standby database will frequently have to access the primary database to replenish the cache, which can increase the load and potentially lead to performance degradation.

E: Global Sequences should have the NOORDER and CACHE options set. The NOORDER option ensures that sequence numbers are provided without guaranteeing sequence order, thus improving scalability and performance. The CACHE option is used to specify how many sequence values will be held in memory for faster access.

Option B is incorrect as the LOG_ARCHIVE_DEST_n parameter's definition for standbys pointing back to the primary does not directly pertain to the creation of sequences.

Option C is incorrect because there is no requirement that the size of the cache for a sequence must be at least 100. The CACHE size can be set to a different number based on specific use cases or performance considerations.

I think option B is also true. A LOG archive_dest_n parameter is indeed required in the standby.

I agree with The size of the CACHE must be carefully considered to avoid performance issues.

I disagree with I believe option D is true as well. If CACHE size is too small, it will affect performance.

I think option A is true because global sequences always impact performance.

I'm not sure about that one, Casie. We should verify the documentation to confirm.

But do you think statement A is true? Is there always a performance impact on the primary database when using global sequences?

That makes sense, Felton. Having the parameter defined is crucial for global sequences to work with a physical standby.

I agree with you, Janine. If the CACHE size is too small, there could be a performance impact on the standby.

I think statement C is true because the CACHE option needs to be at least 100.

Yeah, no kidding. I bet the exam writer was chuckling to themselves when they came up with this question. 'Let's see if they know the ins and outs of Global Sequences on a physical standby database!' Good luck to all of us!

Yeah, me too. This looks like it's testing some pretty advanced Oracle concepts. I'll have to do some research on these features before the exam.

I'm not sure about this question. It seems to be asking about some specific Oracle database features that I'm not too familiar with. Global Sequences and Real-Time Query are new to me.
