Your database supports an OLTP system.
Examine the parameter values configured in your database:
The CUSTOMERS table contains 8,000 rows. The CUST_ID column is the primary key and the
COUNTRY_ID column contains only three possible values: 1111, 2222, and 3333.
You execute the commands:
SQL> EXECUTE DBMS_STATS.GATHER_TABLE_STATS('SH','CUSTOMERS');
PL/SQL procedure successfully completed.
SQL> CREATE INDEX COUNTRY_IDX ON CUSTOMERS (COUNTRY_ID);
Index created.
You then perform a series of INSERT, UPDATE, and DELETE operations on the table.
View the Exhibit to examine the query and its execution plan.
Which three options would improve the performance of the query? (Choose three.)
A. creating a histogram on the COUNTRY_ID column
B. creating a SQL profile

Your database supports an OLTP workload during the day and batch processing at night. You want to monitor performance metrics to detect any degradation of performance in both types of workloads over a time period of 30 days.
Examine this list of possible steps:
1. Create a fixed baseline.
2. Create a baseline template.
3. Create a new moving window baseline.
4. Increase the retention period default value to 30 days.
5. Increase the size of the existing moving window baseline to 30 days.
6. Create warning and critical alerts for the relevant metrics.
7. Enable adaptive thresholds to detect the workload patterns and specify a high-significance-level threshold type.
QUESTION NO: 5

What must you do to analyze and generate recommendations for the SQL statements in the STS?
A. Submit the STS as input to the SQL Access Advisor to generate recommendations for SQL profiles.
B. Submit the STS as input to the SQL Performance Analyzer to generate recommendations for creating indexes and materialized views.
C. Submit the STS as input to the SQL Tuning Advisor to generate recommendations for SQL plan baselines.
D. Submit the STS as input to the SQL Tuning Advisor to generate recommendations for indexes or
SQL profiles or both.
