What three actions could you perform to improve the response time of the queries without modifying the SQL statements?
- A. Create an STS for the statements, run SQL Access Advisor for the STS, and implement any generated recommendations for materialized views.
- B. Set QUERY_REWRITE_ENABLED to TRUE at the instance level.
- C. Set the QUERY_REWRITE_ENABLED to TRUE at the session level.
- D. Set QUERY_REWRITE_INTEGRITY to ENFORCED at the instance level.
- E. Create an STS for the statements, run SQL Tuning Advisor for the STS, and implement any generated recommendations for materialized views.

Examine Exhibit 1 to view the query and its execution plan.
Examine Exhibit 2 to view the structure and indexes for the EMPLOYEES and DEPARTMENTS tables.
Examine Exhibit 3 to view the initialization parameters for the instance.
Why is sort-merge join chosen as the access method?
- A. Because the OPTIMIZER_MODE parameter is set to ALL_ROWS.
- B. Because of the LIKE operator used in the query to filter out records
- C. Because the data is not sorted in the LAST_NAME column of the EMPLOYEES table

Which statement is true about the execution?
- A. Rows are fetched from the SALES table, and then a hash join operator joins with rows fetched from indexes on the PRODUCTS table.

What must be done to ensure that an optimizer uses the latest statistics of the table?
- A. Set the STALE_PERCENT preference to 0.
- B. Use the FIRST_ROWS_n hint in the queries.
- C. Set the OPTIMIZER_MODE parameter to ALL_ROWS.
- D. Set the OPTIMIZER_DYNAMIC_SAMPLING parameter to 0.
- E. Unlock and gather statistics for the table after inserts are done and lock them again.
Correct Answer: E 🗳️
Explanation: Only visible for ActualPDF members. You can sign-up / login (it's free).
You are administering database that supports an OLTP workloads. Most of the queries use an index range scan or index unique scan as access methods.

- A. When the statistics for the table are not current.
- B. When highly selective filters is applied on an indexed column of a table with sparsely populated blocks.
- C. When the histogram statistics are not collected for the columns used in where clause.
- D. When the rows are filtered with an IS NULL operator on the column with a unique key defined
- E. When a highly selective filter is applied on the indexed column and the index has very low value for clustering factor.
