Question

Quizplus · Accepted Answer

Oracle uses the user session to keep track of sequence information and ensure that each user receives a unique sequence number. This allows multiple users to access the same sequence without receiving duplicate numbers. Option A and C are incorrect because multiple users can access the same sequence, and Oracle does not create a separate copy of the sequence for each user. Option D is incorrect because Oracle's sequence generator is designed to ensure that each number is unique.
