Eigentlich handelt es sich bei "Oracle Database 11g: New Features" um ein sehr interessantes Thema. Doch mußte ich leider feststellen, dass der Code im Buch enorm viele Fehler enthält und meines Erachtens zumindest teilweise gar nicht getestet wurde. So sind teilweise Syntaxfehler, manchmal auch Dreher und ähnliches enthalten. Den Test und die Einarbeitung in das Thema macht das zum Teil etwas schwierig. Kleinere Fehler sind auch im Text immer wieder enthalten. So muss alles einzeln geprüft und mit der Dokumentation verifiziert werden. Alles in allem: anstrengend und zeitaufreibend. Den Autoren muss man zugute halten, dass sie unter grossem Zeitdruck gearbeitet haben. Dennoch: Mir wäre lieber gewesen, das Buch erscheint später und dafür ist der Code besser getestet.

Um einen aktuellen Wissensstand bzgl. des Datenbankssystems Oracle zu besitzen, gilt es bei jeder neuen Version eine Fülle von Originalunterlagen zu wälzen, viele Tests durchzuführen usw., um echte praxistaugliche Neuerungen von reinen Werbeversprechen unterscheiden zu können, veränderte Verhaltensweise des Systems nachvollziehen zu können etc.
Das Buch von S.Alapati und C.Kim unterstützt bei all diesen Punkten ausgezeichnet. Es ist fachlich fundiert, absolut praxisnah & didaktisch rund.
Wenn es noch eine gute deutsche Übersetzung für das (recht leicht lesbare) englische Original gäbe, würde ich sogar einen 6.Stern vergeben ;-) ...

HASH(0x900b65b4) von 5 Sternen It's ok. Problems with examples and incorrect information 29. Dezember 2007
Von LoveOracleBooks - Veröffentlicht auf Amazon.com
Format: Taschenbuch
I was very excited to get this book. I like to stay current on Oracle database product changes. There is a great deal of information here (I have the other New Features book from Freeman but have not read it yet).

I have found a few problems with the text (I'm still reading it to be honest). First, several of the examples have errors in the code and generated errors when I tried to run them.

One such case is on page 146. A SQL query demonstrated there has some two obvious SQL errors. Clearly it was not tested, because it could not have run without an error (it bombed on me).

Another example is on page 166 where we find dbms_scheduelr instead of dbms_scheduler. A typo, yes, but one easily caught if the examples were tested.

Another example is on page 165 with a call to dbms_scheduler.set_attribute which has a typo. There are others, but you get the idea. It would also be nice if the code was available online somewhere.

The bottom line is that it seems that at least part of this code was not tested.

It also seems that the authors wrote part of this book on the 11g beta. I ran into one problem with the discussion on invisible indexes. The book indicates that you can use hints to force the use of an invisible index. When I tried this, it did not work (this drove me crazy as I was wondering what I was doing wrong!). After some research I found out that this was true in the beta but was not true in the final production cut of Oracle. Another example of what I think is a beta leftover has to do with SQL Query Result Caching. When I was trying this feature I found I could not set result_cache_mode to AUTO as documented in the book (page 176). When I looked in the Oracle documentation I found that AUTO was not a supported value.

Another problem I have is that examples are incomplete. For example, on page 162 there is a discussion on lightweight jobs. The examples are incomplete. I had to go figure out how to create a program (I had not used the scheduler before to be honest) before I could create the lightweight job. I spent about an hour fiddling with this, because another thing not pointed out by the author (or clearly in the documentation to be honest) are the restrictions on lightweight jobs. I know it's a new features book, and maybe I should know the scheduler, but I think at least the examples should be self-contained if possible.

Another twist appears on page 329. The author talks about a new feature that will eliminate failed loads on external tables. The only problem is that he does not give us any detail on how to actually use this new feature. Instead we get an example of how to create a table in Oracle 10g and he moves on to other features.

In the end, 3 stars seems about right to me. A lot of work went into this book, and I think I learned quite a bit about 11g, but I question now some of what I learned based on problems I've run into. I'll be reading the Freeman book mentioned by another review, shortly. It should provide a good contrast and check and balance.

HASH(0x900b611c) von 5 Sternen very good book written in a hurry 12. Januar 2008
Von Ahmed Baraka - Veröffentlicht auf Amazon.com
Format: Taschenbuch
I selected this book because it's written by Alapati. I've read excellent books before by this author. Unluckily, this one is not among them.
I've finished reading the first three chapters and so far I found too many typing errors, errors in the code and unprecise statements. Obviously it was written in hurry.
All in all, this book does its purpose to me to learn Oracle 11g new features but I expected higher quality from Alapati and Apress.

HASH(0x900b650c) von 5 Sternen Kindle version illustrations impossible (nearly) to read 11. April 2010
Von Amazon Customer - Veröffentlicht auf Amazon.com
Format: Taschenbuch
Taking into account the shortcomings of this book detailed in previous reviews, I found that there were really no alternatives to read while travelling if I wanted to prepare for the 11g upgrade exam. The book is OK to read, but since I was on the road, I opted for the Kindle version. I found that there is a technical problem with doing this, as the illustrations that include text (screen shots, report illustrations) are nearly impossible to read on a Kindle! I believe that the text has been reviewed adequately in the previous posts, but I hadn't seen this warning before... so people can keep this in mind when in the same situation I was in and contemplate a Kindle version rather than the hard copy. Also, you don't (obviously) get the referenced CD with the Kindle.

HASH(0x8fcea834) von 5 Sternen Decent 11g New Features Book 30. April 2008
Von Eric B - Veröffentlicht auf Amazon.com
Format: Taschenbuch
For the most part it was a decent book and gave me a great overview of the new features in Oracle 11g. However there are quite a few typos and a bit of inaccurate information (result_cache_mode = AUTO is not valid/supported).

I wouldn't say this is a bad book - it's a nice read and contains the majority of the information. I am impressed by it being one of the first 11g books out. The authors put in a lot of hard work and I congratulate them.

HASH(0x8fb14720) von 5 Sternen Oracle Database 11g Review 2. September 2008
Von George Loewenthal - Veröffentlicht auf Amazon.com
Format: Taschenbuch Verifizierter Kauf
This is the first book I have read from Sam Alapati and Charles Kim. Coincidently or not, Sam is also the author of the "OCP Oracle Database 11g: New Features for Administrators Exam Guide (Exam 1Z0-050)" book.
After completing this book I am very happy with what I have learned. The authors are very thorough in their coverage of the new features in 11g and do a good job of providing applicable real world examples.

Chapter 9 on ASM covered the new features well and Oracle has made some nice improvements. ASM is a growth area for Oracle and am looking forward to it becoming friendlier and easier to use. Moving files in and out of ASM has been made easier in Oracle 11g.

Chapter 11 on Application Development will be best utlized by developers or DBA's that are involved with development beyond the intermediate level. This chapter also introduces DBAs to APEX.

Chapter 12 is one of the most important chapters. This chapter focuses on Data Warehousing and includes the new partitioning features. The examples are easy to understand and are applicable to the real world. This chapter also does an excellent job on explaing Oracle's next generation LOBs called "Secure Files". This is a must read chapter.

If I could have added a chapter to this book it would be a chapter dedicated to RAC. Even though 11g does not bring too many new features to RAC it does have a few. For example the new features on parallel execution I do not think are mentioned. Their are also enhanced configuration assistants that can be better explained and can be found in a single place.

Overall this is an excellent book and for someone who is just starting to work with 11g this is the best place to start.
