To answer this question, you need to understand the different advisors in Oracle Database that help with tuning and optimization.
Option A) SQL Tuning Advisor - This option is incorrect because the SQL Tuning Advisor is responsible for analyzing individual SQL statements and suggesting improvements to their execution plans. It focuses on optimizing SQL query performance, not the allocation of memory within the database.
Option B) SGA Tuning Advisor - This option is incorrect because the SGA Tuning Advisor is responsible for analyzing the System Global Area (SGA) configuration and making recommendations for optimizing memory allocation for different components of the SGA, such as the Shared Pool, Large Pool, and Buffer Cache. However, it does not specifically determine if the space allocated to these areas is adequate.
Option C) Memory Advisor - This option is correct because the Memory Advisor is responsible for analyzing the memory usage within the database and making recommendations for the optimal allocation of memory to different components, including the Shared Pool, Large Pool, and Buffer Cache. It determines if the space allocated to these areas is adequate and suggests changes if necessary.
Option D) Pool Advisor - This option is incorrect because there is no specific advisor named "Pool Advisor" in Oracle Database. It is not responsible for determining the adequacy of space allocation in the Shared Pool, Large Pool, or Buffer Cache.
The correct answer is C) Memory Advisor. This option is correct because the Memory Advisor analyzes the memory usage and determines if the space allocated to the Shared Pool, Large Pool, or Buffer Cache is adequate.
