The design of Oracle database system should give attention to both performance and data reliability. Which reliability designs will reduce the performance of Oracle?
I'm going with C. Archive Mode. It's like trying to run a marathon while carrying a 50-pound backpack. Sure, it's reliable, but it's gonna slow you down!
A. Multi-mirror log groups are a great way to ensure data reliability, but the additional I/O required can definitely impact performance. It's a tradeoff.
B. Using Oracle RAC is a great way to improve performance and reliability, but it can also add complexity and potentially impact performance in certain scenarios.
I think the answer is C. Archive Mode. It's designed to ensure data reliability, but it can impact performance due to the additional overhead of archiving logs.
