First, let’s take a look at the price of Oracle certificate, Oracle certification exams each door is 135 U.S. dollars, a total of five examinations, all the examination fees plus some other expenses (books, training, etc.), to the adoption of Oracle certification exam itself , a small investment, but from today’s job market, the reward is still worthwhile.
Many people hope that in IT fields such as Oracle 10g DBA as well-paid - the annual salary of $ 75,000 to $ 140,000. For a veteran of Oracle DBA in terms of their annual salary has risen to $ 300,000. Many of them are Oracle believes that the adoption of the certification, it has been the area of Oracle database permits. However, Oracle certification is only those who have the foresight of the owner of one of the criteria evaluation.
Many IT professionals do not believe Oracle DBA technology in addition to addition to a higher gold content. Under normal circumstances, Oracle DBA can be responsible for database design, operation, backup and restore, but also pay close attention to the entire project development process. Therefore, a successful Oracle 10g DBA must have a strong technical level, but also have an excellent co-ordination, at the same time, the operating system and computer-depth understanding of the theory is also necessary. Therefore, DBA must have a computer professional, professional communications, business management degree or a master’s degree.
OCP certification exam and management in the field of Oracle is a measure of professional and technical level of a master degree of a good standard, but there does not mean you OCP certificate learned Oracle expertise. I’ve seen on a non-computer-related professions, only in this area have a 12-week courses were experienced employment, he had all the courses are aimed at the adoption of OCP examinations. However, many get OCP certificate, contact IT industry is only 12 weeks and were not able to fully understand the concepts of Oracle management. I have just seen a person get OCP certificate Oracle database management does not understand some basic concepts, this person not be a lot of things related to consider together. A certificate does not necessarily qualify
Remember, Oracle Certification only candidates for employers to understand that the Oracle database through a technical examination. In fact, Oracle certification is only one measure of a candidate one of the criteria, there are other criterias:

Excellent interpersonal skills: Oracle DBA usually IT industry and technical experts to deal with, so he or she must be able to visit the Oracle database for all the developers or programmers clear explanation of the concept of Oracle. In some cases, Oracle DBA is a management personnel, and therefore also asked him to participate in the strategic development plan as well as a database designed to have excellent interpersonal skills.
Oracle most successful professionals are asked by the computer or bachelor’s degree in information systems. For higher office, such as Oracle DBA, many employers are asking for a master’s degree in computer science or MBA.
Practical experience: This is a new certificate with the OCP people are most concerned about one thing. OCP has been a lot of work experience and no certificate of people are complaining there is no OCP certificates would not have work experience, no work experience, there will be no work. This is the talent market is now on a very difficult problem.
Database of theoretical knowledge: In addition to master the required technology OCP knowledge, a successful professionals as well as Oracle databases and database design and related software, including the standardization of database theory and the use of Unified Modeling Language (UML) face to the object model, of course, there are other methods of database design-related knowledge, such as CORBA and J2EE.
OCP can not completely measure the actual level of a person (the most important thing is can not judge his work experience), he was just a non-IT industry to enter the area to provide a way to Oracle.
In this section, we mainly look at the Oracle certification process and to further explain the Oracle exams. To further enhance the Oracle certification optional, Oracle can now provide four kinds of different certification, which are designed for working in the field engaged in Oracle, including DBA, developers and managers designed.
Oracle professional DBA Certification: This is the Oracle database management for the design of a basic certification (4 examinations)
Oracle Web Application Developer Certification: This is on SQL, PL / SQL and network development of a certification (4 examinations)
Oracle Java Developer Certification: This is a company together with Sun’s Java designed for the Oracle developer certification, a total of six examinations, as well as Sun and Oracle certifications

First, let’s look at the most popular application on the Oracle OCP certification DBAs.
