From an java developer's point of view, is it worthwhile (time-wise) to take the oracle 10g certifcation (either the OCA or OCP)? The certification seems to be geared towards DB admins.

unless you want to be an Oracle DBA. Oracle's certification is only good
for Oracle DB, not for Java, J2EE, portal, or web services,....

No I partialy disagree with you.
Because twice when we face a problem in our application mostly developers don't have DB vision and they look for solution only in application, our developer are stronger than me but I provided wise solution for problem on DB side, and they appreciated me
It is not related to developement but it make sense to have it.

Another example is once we have a project for our test environment and I should do lots of hardcoding, the project easily implemented because of my knowledge about oracle's data dictionary.

My OCP give me a very good ideas in developement.

Personally, it is better to have some knowledge with applications that you might always work with. This can improve the system infrastructure/performance if you know the 'features' of certain applications.

There has been an ongoing argument about where to put business logic: middle layer or back storage. One of OCP I know does not like to (or can not) use middleware at all. I agree knowledges on DB is important and helpful: queries, data modeling, stored procedure (not use it for business logic), triggers, ...

I think Oracle SQL (9i) - Exam IZO-007 is quite useful for Java developers but 10g exams are very admin directed. I suggest you go for 007 exam (9i) since it is equally relevant for 10g.

Hello. I just passed SCJP yesterday . I do not really know what to do next but besides a SCWCD certification I would also need something on databases.
I want to get OCP9i .
My question is : Do I need to go through their outrageaous priced training ?(Sun does not force you to use their training).
I would like to buy a study guide and prepare as I did for SCJP trough practice.
I know there are 2 exams for OCA9i and the some other to get OCP . What can you say about this ?

Hi

Oracle basically has two developer certifications paths:
PL-SQL - It a certification language test, like SCJP
Forms - Its is a proprietary web based GUI used by Oracle only.

I think that Forms certification it is not necessary at all. Usually companies only look for this kind of skill if they use Oracle's ERP software (Oracle Applications - this is my case) or they don't want to use any middleware (like J2EE for example). Botton line: PL-SQl has a broader range.

Thank you Mr. Americo Suiza.
I understand what you say. The point is that my company will pay for only one certification at a time and I do not know whether they will agree with this high price tag for OCP9i.
Basically I would like to have something that says : You can program in Oracle SQL and PL/SQL ... like the one I have for Java.

Mihaio,

So you should try "Oracle PL/SQL Developer Certified Associate" (OCA) certification. I took the following tests:

1Z0-001 Introduction to Oracle: SQL and PL/SQL.
1Z0-147 Program with PL/SQL

I used the following books:
- Oracle 8i Certified Professional - SQL & PL/SQL Exam Guide (Exam 1Z0-001)
Jason S. Couchman - ISBN 0-07-219153-8
- Very good book. Covers all the exam subjects

- Oracle Developer PL/SQL Program units exam guide (Exam 1Z0-101)
Steve O' Hearn - ISBN 0-07-219336-0
- Very good book as well. Unfortunately it covers only 80% of the exam. Some topics for 1Z0-147 are not covered. You have to search for additional sources.

I personally recommend, Feurstein books. They are the bible for any PL-SQL developer.

At [ UD: removed link to copyrighted material ] you can find some old editions of PL-SQL books. They are still valid for certifications purposes.
