So I guess the "Oracle Certified Expert, Oracle Database 11g Release 2 SQL Tuning" would be the logical next step?i would agree.
Is "Oracle Certified Expert, Oracle Database 11g Release 2 SQL Tuning" too complicated for me.You don't know what's in the test. This is wonderful news. Studying for the test will teach you lots of new things about writing and tuning SQL. In my posts one concept gets repeated over and over again. The value of a certification is not in getting a piece of paper to stick in a filing cabinet. The value comes in what new skills you gain in getting ready to pass the test. If you don't know the information and you don't study for the test, than yes, you won't pass it. If you prepare for the test until you do understand the objectives, then you should be able to pass the test.
Because I don't have experience with topics listed in objectives, mostly never heard of.
What study guide?None exist yet. There's no doubt that I will be writing a study guide for this exam. It won't be out until sometime after the test is in production. I don't publish guides for which I don't hold the certification. You don't have to wait for it though. You can use the exact same source I will use in creating it -- the Oracle documentation. I guarantee that every single topic on the OE page and every single question that is on the exam is answered somewhere in the documentation.
