Oracle DBA / DBMS post Interview Questions with Detailed Solutions - 3

1. Explain the difference between a hot backup and a cold backup and the benefits associated with each. - A hot backup is basically taking a backup of the database while it is still up and running and it must be in archive log mode. A cold backup is taking a backup of the database while it is shut down and does not require being in archive log mode. The benefit of taking a hot backup is that the database is still available for use while the backup is occurring and you can recover the database to any point in time. The benefit of taking a cold backup is that it is typically easier to administer the backup and recovery process. In addition, since you are taking cold backups the database does not require being in archive log mode and thus there will be a slight performance gain as the database is not cutting archive logs to disk.

2. You have just had to restore from backup and do not have any control files. How would you go about bringing up this database? - I would create a text based backup control file, stipulating where on disk all the data files where and then issue the recover command with the using backup control file clause.

3. How do you switch from an init.ora file to a spfile? - Issue the create spfile from pfile command.

4. Explain the difference between a data block, an extent and a segment. - A data block is the smallest unit of logical storage for a database object. As objects grow they take chunks of additional storage that are composed of contiguous data blocks. These groupings of contiguous data blocks are called extents. All the extents that an object takes when grouped together are considered the segment of the database object.

5. Give two examples of how you might determine the structure of the table DEPT. - Use the describe command or use the dbms_metadata.get_ddl package.

6. Where would you look for errors from the database engine? - In the alert log.

7. Compare and contrast TRUNCATE and DELETE for a table. - Both the truncate and delete command have the desired outcome of getting rid of all the rows in a table. The difference between the two is that the truncate command is a DDL operation and just moves the high water mark and produces a now rollback. The delete command, on the other hand, is a DML operation, which will produce a rollback and thus take longer to complete.

8. Give the reasoning behind using an index. - Faster access to data blocks in a table.

9. Give the two types of tables involved in producing a star schema and the type of data they hold. - Fact tables and dimension tables. A fact table contains measurements while dimension tables will contain data that will help describe the fact tables.

10. What type of index should you use on a fact table? - A Bitmap index.

11. Give two examples of referential integrity constraints. - A primary key and a foreign key.

12. A table is classified as a parent table and you want to drop and re-create it. How would you do this without affecting the children tables? - Disable the foreign key constraint to the parent, drop the table, re-create the table, enable the foreign key constraint.

13. Explain the difference between ARCHIVELOG mode and NOARCHIVELOG mode and the benefits and disadvantages to each. - ARCHIVELOG mode is a mode that you can put the database in for creating a backup of all transactions that have occurred in the database so that you can recover to any point in time. NOARCHIVELOG mode is basically the absence of ARCHIVELOG mode and has the disadvantage of not being able to recover to any point in time. NOARCHIVELOG mode does have the advantage of not having to write transactions to an archive log and thus increases the performance of the database slightly.

14. What command would you use to create a backup control file? - Alter database backup control file to trace.

15. Give the stages of instance startup to a usable state where normal users may access it. - STARTUP NOMOUNT - Instance startup. STARTUP MOUNT - The database is mounted. STARTUP OPEN - The database is opened

16. What column differentiates the V$ views to the GV$ views and how? - The INST_ID column which indicates the instance in a RAC environment the information came from.

17. How would you go about generating an EXPLAIN plan? - Create a plan table with utlxplan.sql. Use the explain plan set statement_id = ‘tst1′ into plan_table for a SQL statement. Look at the explain plan with utlxplp.sql or utlxpls.sql

18. How would you go about increasing the buffer cache hit ratio? - Use the buffer cache advisory over a given workload and then query the v$db_cache_advice table. If a change was necessary then I would use the alter system set db_cache_size command.

19. Explain an ORA-01555 - You get this error when you get a snapshot too old within rollback. It can usually be solved by increasing the undo retention or increasing the size of rollbacks. You should also look at the logic involved in the application getting the error message.

20. Explain the difference between $ORACLE_HOME and $ORACLE_BASE. - ORACLE_BASE is the root directory for oracle. ORACLE_HOME located beneath ORACLE_BASE is where the oracle products reside

9. Read the following code:
   

   CREATE OR REPLACE PROCEDURE find_cpt
   (v_movie_id {Argument Mode} NUMBER, v_cost_per_ticket {argument mode} NUMBER)
   IS
   BEGIN
    IF v_cost_per_ticket  > 8.5 THEN
   SELECT  cost_per_ticket
   INTO            v_cost_per_ticket
   FROM            gross_receipt
   WHERE   movie_id = v_movie_id;
    END IF;
   END;

   Which mode should be used for V_COST_PER_TICKET?

   1. IN

   2. OUT

   3. RETURN

   4. IN OUT

10. Read the following code:
    

    CREATE OR REPLACE TRIGGER update_show_gross
         {trigger information}
        BEGIN
         {additional code}
        END;

    The trigger code should only execute when the column, COST_PER_TICKET, is greater than $3. Which trigger information will you add?

    1. WHEN (new.cost_per_ticket > 3.75)

    2. WHEN (:new.cost_per_ticket > 3.75

    3. WHERE (new.cost_per_ticket > 3.75)

13. Read the following code:
    

    CREATE OR REPLACE FUNCTION get_budget(v_studio_id IN NUMBER)
    RETURN number IS
    
    v_yearly_budget NUMBER;
    
    BEGIN
          SELECT  yearly_budget
          INTO            v_yearly_budget
          FROM            studio
          WHERE   id = v_studio_id;
    
          RETURN v_yearly_budget;
    END;

    Which set of statements will successfully invoke this function within SQL*Plus?

    1. VARIABLE g_yearly_budget NUMBER
       EXECUTE g_yearly_budget := GET_BUDGET(11);

    2. VARIABLE g_yearly_budget NUMBER
       EXECUTE :g_yearly_budget := GET_BUDGET(11);

    3. VARIABLE :g_yearly_budget NUMBER
       EXECUTE :g_yearly_budget := GET_BUDGET(11);

    4. VARIABLE g_yearly_budget NUMBER
       :g_yearly_budget := GET_BUDGET(11);

14. CREATE OR REPLACE PROCEDURE update_theater
    (v_name IN VARCHAR v_theater_id IN NUMBER) IS
    BEGIN
          UPDATE  theater
          SET             name = v_name
          WHERE   id = v_theater_id;
    END update_theater;

    When invoking this procedure, you encounter the error:

    ORA-000: Unique constraint(SCOTT.THEATER_NAME_UK) violated.

    How should you modify the function to handle this error?

    1. An user defined exception must be declared and associated with the error code and handled in the EXCEPTION section.

    2. Handle the error in EXCEPTION section by referencing the error code directly.

    3. Handle the error in the EXCEPTION section by referencing the UNIQUE_ERROR predefined exception.

    4. Check for success by checking the value of SQL%FOUND immediately after the UPDATE statement.

15. Read the following code:
    

    CREATE OR REPLACE PROCEDURE calculate_budget IS
    v_budget        studio.yearly_budget%TYPE;
    BEGIN
          v_budget := get_budget(11);
          IF v_budget <>

    You are about to add an argument to CALCULATE_BUDGET. What effect will this have?

    1. The GET_BUDGET function will be marked invalid and must be recompiled before the next execution.

    2. The SET_BUDGET function will be marked invalid and must be recompiled before the next execution.

    3. Only the CALCULATE_BUDGET procedure needs to be recompiled.

    4. All three procedures are marked invalid and must be recompiled.

16. Which procedure can be used to create a customized error message?

    1. RAISE_ERROR

    2. SQLERRM

    3. RAISE_APPLICATION_ERROR

    4. RAISE_SERVER_ERROR

17. The CHECK_THEATER trigger of the THEATER table has been disabled. Which command can you issue to enable this trigger?

    1. ALTER TRIGGER check_theater ENABLE;

    2. ENABLE TRIGGER check_theater;

    3. ALTER TABLE check_theater ENABLE check_theater;

    4. ENABLE check_theater;

18. Examine this database trigger
    

    CREATE OR REPLACE TRIGGER prevent_gross_modification
    {additional trigger information}
    BEGIN
          IF TO_CHAR(sysdate, DY) = MON
    THEN
    RAISE_APPLICATION_ERROR(-20000,Gross receipts cannot be deleted on

     Monday);
          END IF;
    END;

    This trigger must fire before each DELETE of the GROSS_RECEIPT table. It should fire only once for the entire DELETE statement. What additional information must you add?

    1. BEFORE DELETE ON gross_receipt

    2. AFTER DELETE ON gross_receipt

    3. BEFORE (gross_receipt DELETE)

    4. FOR EACH ROW DELETED FROM gross_receipt

19. Examine this function:
    

    CREATE OR REPLACE FUNCTION set_budget
    (v_studio_id IN NUMBER, v_new_budget IN NUMBER) IS
    BEGIN
          UPDATE  studio
          SET             yearly_budget = v_new_budget
          WHERE   id = v_studio_id;
    
          IF SQL%FOUND THEN
                  RETURN TRUEl;
          ELSE
                  RETURN FALSE;
          END IF;
    
          COMMIT;
    END;

    Which code must be added to successfully compile this function?

    1. Add RETURN right before the IS keyword.

    2. Add RETURN number right before the IS keyword.

    3. Add RETURN boolean right after the IS keyword.

    4. Add RETURN boolean right before the IS keyword.

20. Under which circumstance must you recompile the package body after recompiling the package specification?

    1. Altering the argument list of one of the package constructs

    2. Any change made to one of the package constructs

    3. Any SQL statement change made to one of the package constructs

    4. Removing a local variable from the DECLARE section of one of the package constructs

21. Procedure and Functions are explicitly executed. This is different from a database trigger. When is a database trigger executed?

    1. When the transaction is committed

    2. During the data manipulation statement

    3. When an Oracle supplied package references the trigger

    4. During a data manipulation statement and when the transaction is committed

22. Which Oracle supplied package can you use to output values and messages from database triggers, stored procedures and functions within SQL*Plus?

    1. DBMS_DISPLAY

    2. DBMS_OUTPUT

    3. DBMS_LIST

    4. DBMS_DESCRIBE

23. What occurs if a procedure or function terminates with failure without being handled?

    1. Any DML statements issued by the construct are still pending and can be committed or rolled back.

    2. Any DML statements issued by the construct are committed

    3. Unless a GOTO statement is used to continue processing within the BEGIN section, the construct terminates.

    4. The construct rolls back any DML statements issued and returns the unhandled exception to the calling environment.

24. Examine this code
    

    BEGIN
          theater_pck.v_total_seats_sold_overall := theater_pck.get_total_for_year;
    END;

    For this code to be successful, what must be true?

    1. Both the V_TOTAL_SEATS_SOLD_OVERALL variable and the GET_TOTAL_FOR_YEAR function must exist only in the body of the THEATER_PCK package.

    2. Only the GET_TOTAL_FOR_YEAR variable must exist in the specification of the THEATER_PCK package.

    3. Only the V_TOTAL_SEATS_SOLD_OVERALL variable must exist in the specification of the THEATER_PCK package.

    4. Both the V_TOTAL_SEATS_SOLD_OVERALL variable and the GET_TOTAL_FOR_YEAR function must exist in the specification of the THEATER_PCK package.

25. A stored function must return a value based on conditions that are determined at runtime. Therefore, the SELECT statement cannot be hard-coded and must be created dynamically when the function is executed. Which Oracle supplied package will enable this feature?

    1. DBMS_DDL

    2. DBMS_DML

    3. DBMS_SYN

    4. DBMS_SQL
