Errata and Enhancements


The test section is not intended to be used as a comprehensive Oracle technical exam, and the technical questions in this code depot are only intended to be examples. The only way to accurately evaluate the Oracle skills of a job applicant is to employ the services of an experienced Oracle DBA and conduct an in-depth technical interview and skills assessment.

Also note that the expected answers from the questions are highly dependent upon the version of Oracle.  We have tried to make the questions as version neutral as possible, but each release of Oracle brings hundreds of changes and new features, and these example questions may not be appropriate for your version of Oracle.  All of the interview questions presented in this book should be administered by an experienced Oracle DBA.


Enhancements to the expected answers are noted in red.


Page 35, question 7


7. What dictionary file tells the size of each database file?


The best answer is dba_data_files, although sys.file$ and sys.v$datafile are also correct.


Page 40, Question 11

11. What are the types of table triggers ?


 Skill Level:  Intermediate to High


Expected Answer: There are 12 types of triggers  in PL/SQL  that consist of combinations of the BEFORE, AFTER, ROW, TABLE, INSERT, UPDATE, DELETE and EACH key words. 








Page 44, Question 10

10.  (On UNIX ) When should more than one DB writer process be used? How many should be used?


Skill Level: High


Expected answer: If the UNIX  system being used is capable of asynchronous IO, then only one is required. If the system is not capable of asynchronous IO, then up to twice the number of disks used by Oracle number of DB writers should be specified by use of the initialization parameter for your Oracle release that sets the number of DBWR processes.


Async IO usually indicates a multi-threaded model for disk access will be used and Oracle states several times that with async IO most systems don't need multiple db writers, however, in some cases multiple db writers can be helpful. The number varies from twice the number of cpus to the number of disks expected to be used, which ever value is smaller

Hear what people are saying:

Ted from the Bay Area, CA says:

This was very enjoyable read and I'm very happy to see that many of the details about using the Oracle9i dynamic SGA are revealed. The problem has always been that the Oracle documentation tells you about the new features yet fail to tell you about how to apply them.

After reading this book I was able to understand the automatic-tuning methods in Oracle10g and they made sense because the author revealed some of the mechanisms that they use. The online scripts are very nice also, with many I had never seen before.

Martin from San Francisco, CA says:
This book is a great help to me as an IT manager that lacks knowledge of Oracle but routinely needs to hire Oracle DBAs. The questions and answers are particularly helpful in the interview process. Selecting technical professionals has always been difficult when I lack the familiarity with the technology to parse between the experienced applicants and those who simply throw around buzz words and catch phrases. Using this text I can grade the applicants and weed out the inexperienced ones.
