The Study of Adjustment and Optimization of Oracle Database in Information System

With the increasing amount of data of information system, it is necessary to adjust the performance of oracle database and optimization, in order to meet the demand of long-term use of the information system´s data. In this article, based on oracle database performance evaluation and influence factors analysis, we choose a method for better improvement and study of oracle memory structure, and find a way to adjust and optimize the memory allocation, after that apply it to the existing information system. Finally, through the comparison of the oracle database performance change, we come up with the idea that adjust memory allocation can improve database performance of information systems.
