Question 1 of 30

A database administrator is tasked with optimizing an Oracle Database 19c instance that experiences performance issues during peak usage times. The workload is characterized by a mix of read and write operations, with a significant number of concurrent users. After analyzing the performance metrics, the administrator considers adjusting the memory allocation for the SGA and PGA. Which approach should the administrator take to achieve the best performance improvement?

Increase the SGA size to enhance data caching for read operations while monitoring the PGA for write operations.

Decrease the SGA size to allocate more memory to the PGA, assuming that write operations will benefit from increased memory.

Set both the SGA and PGA to their minimum values to free up system resources for other applications.

Increase the PGA size significantly while leaving the SGA unchanged, as write operations are the primary concern.
