     THEN
     RAISE_APPLICATION_ERROR(-20000,Gross receipts cannot be deleted on

     Monday);
           END IF;
    END;

    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

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

Oracle DBA interview questions

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
