There seems to be no such authority in Harbin. If you want to get OCP certificate, you must go through the original factory training or WDP channel authorized by Oracle Bone Inscriptions. If you participate in the original factory training, the cost is not less than 30 thousand, because the price is too high, so generally fewer people will choose this way; Most people will choose to attend OCP training courses in Oracle Bone Inscriptions officially authorized training center. WDP Center in Chongqing is located in Shiqiaopu, Oracle Bone Inscriptions, Sizhuang, Chongqing, and it is also one of the few professional DBA training institutions in China.

At present, most OCP certification courses in training institutions are Oracle 1 1g, which requires three exams. The cost of each exam is almost RMB 1500, and OCP certification can only be obtained if all three exams are passed.
