Start contact Oracle, in June 2003, participated in a project, developed using PL / SQL and Pro * C. Programming is relatively easy, and later discovered that he did not know how Oracle started and closed (previously used SQL Server and MySQL). In the design, the external process (ExterNel Routine) needs to be called, and this external process is also access to the database (this external program is implemented by Pro * C). The program is written very simple, but during the test process, it is always wrong. In the process of survey, it has begun to understand Oracle in-depth, knowing Oracle_SID, Service_name and other concepts, and discovers one problem in the design. At this time, it is interested in Oracle. At that time, there was a very nice Oracle entry (why did you remember), a preliminary understanding of the architecture of Oracle 9i. The company organized a 3-day short-term Oracle training, with an initial understanding of Oracle's backup and recovery. During this time, I set my own development direction on the route of Java Linux Oracle (all of Free, although Oracle spends money during actual deployment), this is what I want to participate in the OCP test. The OCP exam is really expensive, especially to get 9i must participate in a factory training, more than 9,000, this thought is basically canceled. I am a certification fan, I haven't participated in any certification yet. I feel that I can learn the purpose of learning. Although the later work is also related to Oracle, it is only related. Connect Oracle through JDBC, basically in contact with any Oracle-specific knowledge. I have begun to consider replacement work, and I will have an idea of OCP and resurrected. But it is more than 20,000 yuan in the flower, after all, it is a bit uncomfortable. Some people have taken OCP in the company, but isn't it the same job? After discovering the Oracle University Library, I have a lot of heart, 12,000, a better than 20,000. Later, it can be described as "peak circuit", I have not replaced work, the company invites the Oracle training teacher to the company to conduct OCP training, and let me take the OCP test. After more than a month after training (we have two days a week), it is now ready to test. The way the exam is, first test 8i, upgrade to 9i. 8i exam is going to expire, time is more tense. I first examine 1Z023, Administration and Architecture. Time is October 22. I at the time of training materials is the set of Sybex and Electronic Industry Press. (The textbook is 9i), read half, can't see it, let me not say that it is not authentic, some are wrong. After a few days, I think I still look at the SG, English version, and most of the words don't know, I don't understand that I don't understand if each word knows. Efforts to learn .....
