Question 41
In your multitenant container database (CDB) containing pluggable database (PDBs), the HR user
executes the following commands to create and grant privileges on a procedure:
CREATE OR REPLACE PROCEDURE create_test_v (v_emp_id NUMBER, v_ename VARCHAR2,
v_SALARY NUMBER, v_dept_id NUMBER)
BEGIN
INSERT INTO hr.test VALUES (V_emp_id, V_ename, V_salary, V_dept_id);
END;
/
GRANT EXECUTE ON CREATE_TEST TO john, jim, smith, king;
How can you prevent users having the EXECUTE privilege on the CREATE_TEST procedure from
inserting values into tables on which they do not have any privileges?

Question 42

SQL> DBMS_STATS. SET_TABLE_PREFS ('SH', 'CUSTOMERS', 'PUBLISH', 'false');
What is the effect of executing this command?

Question 43
Examine the parameters for a database instance:
Your database has three undo tablespaces and the default undo tablespace is not autoextensible.
Resumable space allocation is not enabled for any sessions in the database instance.
What is the effect on new transactions when all undo space in the default undo tablespace is in use by active transactions?

Question 44
In a recent Automatic Workload Repository (AWR) report for your database, you notice a high number of buffer busy waits. The database consists of locally managed tablespaces with free list managed segments.
On further investigation, you find that buffer busy waits is caused by contention on data blocks.
Which option would you consider first to decrease the wait event immediately?

Question 45
You create an Oracle 12c database and then import schemas that are required by an application which has not yet
been developed.
You want to get advice on creation of or modifications to indexes, materialized views and partitioning in these
schemas.
What must you run to achieve this?
