Bogus information for Becoming Another User! 20 mars 2012
Par Reginald - Publié sur Amazon.com
Format: Broché Achat vérifié
In the book and ebook in Chapter 9 Database Security and Auditing , the authors have cut and pasted the classic Becoming Another User method used in previous issues of their book and previous versions of Oracle.

select password from dba_users
2 where username = 'SKING';
PASSWORD
------------------------------
83C7CBD27A941428
1 row selected.

In 11g their method does not work. If you select on the dba_users table for the password you only get a null return for it. So their classic method does not work. Instead the correct method is to query using some built in functions, like so:

select
'alter user "'||username||'" identified by values '''||extract(xmltype(dbms_metadata.get_xml('USER',username)),'//USER_T/PASSWORD/text()').getStringVal()||''';' old_password
from dba_users where username = 'USERNAME';

This will yield the following output string :

alter user "USERNAME" identified by values 'F894844C34402B67'

I would expect an suthor of Mr. Loney's caliber and Mr. Bryla's stature to have adequately done their homework. If they got this little item wrong, what other items did they get wrong in their book?
I have read every one of the Handbooks since Oracle7 and I have enjoyed them tremendously. They have saved the day for myself and many other DBAs. But when you are a trusted source, we expect you to have validated your work and assumptions. I realize it is one minor gaff, but the repercussions could be huge.

I am glad my boss asked me to verify that the Becoming Another User method in your book actually worked, otherwise I would have been left in a bad situation.

I hope you guys put out an errata to correct these errors. Is there a web site with the corrections? For the owners of the printed copy (I own the printed copy and the ebook) getting the word to them might be a little more difficult.

The rest of the book was good, but no longer so excellent. If this error has already been identified and addressed, then thank you.
If not, shame on you and your technical proofer for not finding it.
Okay, Add It To The Shelf If Someone Else Foots The Bill 26 juin 2015
Par Stephen Mann - Publié sur Amazon.com

Most of the time I find myself needing the content in this book to be about 1.5 to 2 times more than I get. Don't get me wrong, there have been plenty of times I found what I wanted, but the book really needed to be thicker (and therefore more expensive) to be the Swiss Army Knife I need. Maybe it should have been a double volume affair. like the Sams "Unix Unleashed" became in its most useful iteration. I dunno.

There are some topics that are simply appetite-whetters too, requiring a further search for information before whatever it is can be of use.

People often say, and in this specific case they are right, that there is no substitute for the Oracle Manual. I guess this was intended as a more detailed quick-start guide than the 2-day admin manuals.

Good, useful, but in no way indispensable.
