Everything you want to know about the 1z0-045 test

September 13th, 2008

Q. What is the pre-requisite for taking the 1z0-045 test?

A. 1z0-045 is an upgrade test for all Oracle 8i OCPs (1z0-020). Therefore, to give 1z0-045, you must be 8i OCP. 1z0-045 is titled as Oracle Database 10g DBA New Features for Oracle8i OCPs. The best way to study for any certification is self-studying and getting hands on the software.

Q. How can I register for the test?

A. You can register yourself through the Oracle registered testing centers. After getting yourself registered for the test, you can contact the testing center to know the schedule (date and time) of your test. Oracle certifications can be taken only at authorized Prometric testing centers worldwide. The test date may depend on your choice (and availability of slot) in your selected test center. You may choose to register yourself online at Prometric Website .

Everything you want to know about the 1Z0-040 test

August 28th, 2008

Q. What is the pre-requisite for taking the 1Z0-040 test?

A. The prerequisite for the 1Z0-040 test is Oracle Database 10g: New Features for Administrators Release 2 (1z0-030). The 1Z0-040 (OCP) is a step that upgrades your 9i OCP credential to 10g credential. Generally, one test is required for OCPs to upgrade to each new release of an Oracle DBA track. The Oracle Database 10g certification track is a step towards a successful career as an Oracle professional. However, you must be well experienced with the SQL before you take the test. Self-studying and self-schooling can certainly help you prepare for the test. This will require a lot of dedication and practice managing a database and newly added features in 10g.
