The only purpose I learned OCA exam is because I think this is the best way to obtain the key skills.During the past 3 months, I am sure I totally digested this book. If you only read this book and you do not have so much practical experience, I am sure you can not pass. Fortunately, I passed, but the score is very tentative.I am not a DBA.
Does the "self test" over kill. I have the feeling, the knowledge in the book is too out-of-date. After taking the real exam, I found the difficulty of the real test is between the self tests and the book.
Well,well, I just came back from the testing center. I ordered the "self test" and found I can only pass 50% in the mock tests. However, I really had not any better books to read for the test.Good luck guys.
I have very little experience in administrating oracle database. But finally I found this book is far from enough to pass the test.
If you're wondering what book you should buy to read, buy THIS ONE.My only complaints are that the question cd is not particularly helpful. I would very much recommend that you buy a question set from a provider on the internet such as Ucertify (just be careful which provider you buy from, as some of them provide the *exact* test questions, which will invalidate your results. Having passed the OCA, I can say that this book has excellent coverage of the OCA exam (and presumably the OCP too). The questions on it aren't particularly close to the actual exam. Ucertify is ok).Also be careful: The last chapter in section 1 (the section on languages and such) is in the OCP exam, not the OCA. I wouldn't bother buying any other study material for reading. The book is very comprehensive, and the topics are broken down into small digestible chapters.
It feels like it was tossed together in 20 minutes from an import of a tab delimited list of questions and answers. Ridiculous. This book will prepare you for the OCA/OCP exams, however, be aware before you start, the self-test software has the exams mismatched. The references for each question in the view section just refer you to the book, as a whole, no chapter number. Scrolling the test review does not work, neither does the print function.If I were the author of certification guides I would guarantee with the utmost certainty that the book was accurate and helpful, by having several non-certified DBAs as _well_ as OCP DBAs review and take the chapter tests.Besides all that, I still give it 4 stars it is well presented, and if this book does not prepare you, then you are probably not doing the self-tests and exercises, and are looking for a cheat-sheet cliff-note format, and I don't want to hire any DBA that needs to be spoon fed to pass a certification. The OCA exam is actually titled "OCP" and vice-versa, so if you cover the 1st half of the book, you'll need to take the "OCP" test on the software, the one with 75 questions.1) Read each chapter2) Take every quiz at the end of chapter3) Score yourself and review each wrong answerBy the time you are done and are ready for the practice test, you will be prepared.I do feel that there are a few too many errors, as other reviewers pointed out, but most of these will only hurt people who are just trying to "cram." For experienced DBAs, the errors will usually be obvious, and can be verified by doing the exercises. That said, errors are errors and should not be there if the book had been properly edited and reviewed.The self-test software gets 2 stars.
Don't expect to pass using just this book. This book has basic info for 10g R1 however exam questions based on knowledge of 10gR2 knowledge of ASM being one of them.
They are always empty in an RDBMS instance".but oracle doc says: "In a database instance, V$ASM_DISKGROUP displays one row for every Automatic Storage Management disk group mounted by the local Automatic Storage Management instance".And talking about ASM one more important thing: there is no information about templates and aliases in ASM file names which one could get on exam test.that's not the complete list of errors i'm afraid.and it's worth to notice that from december '08 the contents of the book won't be enough to get OCA/OCP:http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage.page_id=231.regards.
