The result cache is enabled for the database instance. Examine the following code for a PL/SQL function: CREATE OR REPLACE FUNCTION get_hire_date (emp_id NUMBER) RETURN VARCHAR RESULT_CACHE RELIES_ON (HR.EMPLOYEES) IS date_hired DATE; BEGIN SELECT hire_date INTO date_hired FROM HR.EMPLOYEES WHERE EMPLOYEE_ID = emp_id; RETURN TO_CHAR(date_hired); END; You notice that results for the functions are not used effectively. What do you recommend for better utilization of the result cache? (Choose all that apply.)
A. Set the RESULT_CACHE_MODE parameter to FORCE.
B. Increase the value for the RESULT_CACHE_MAX_SIZE parameter.
C. Add a format mask parameter, such as RETURN TO_CHAR(date_hired, fmt) to GET_HIRE_DATE.
D. Change the return type of GET_HIRE_DATE to DATE and have each session invoke the TO_CHAR function.
