A Correct answer
Explanation

CELL_OFFLOAD_PLAN_DISPLAY determines whether Oracle's EXPLAIN PLAN displays Exadata storage filter predicates. Setting it to AUTO or ALWAYS enables this feature, allowing database administrators to verify if query predicates are offloaded to storage cells. The option False is incorrect because it disables showing these storage predicates.

AI explanation

To answer this question, we need to understand the purpose of the CELL_OFFLOAD_PLAN_DISPLAY parameter and its effect on the SQL EXPLAIN PLAN command.

The CELL_OFFLOAD_PLAN_DISPLAY parameter determines whether the SQL EXPLAIN PLAN command displays the predicates that can be evaluated by Exadata Cell as STORAGE predicates for a given SQL command.

Option A) True - This option is correct. The CELL_OFFLOAD_PLAN_DISPLAY parameter does determine whether the SQL EXPLAIN PLAN command displays the predicates that can be evaluated by Exadata Cell as STORAGE predicates for a given SQL command. If the parameter is set to true, the predicates that can be offloaded to the Exadata storage cells are displayed in the EXPLAIN PLAN output.

Option B) False - This option is incorrect. The CELL_OFFLOAD_PLAN_DISPLAY parameter does determine whether the SQL EXPLAIN PLAN command displays the predicates that can be evaluated by Exadata Cell as STORAGE predicates for a given SQL command.

The correct answer is A) True. This option is correct because the CELL_OFFLOAD_PLAN_DISPLAY parameter does have an effect on whether the SQL EXPLAIN PLAN command displays the predicates that can be evaluated by Exadata Cell as STORAGE predicates for a given SQL command.
