摘要
针对通信行业实践中现有超大型数据库迁移存在方案复杂和难度大等问题,给出基于Export/Import和数据泵技术的数据逻辑迁移解决方案。首先,对Oracle数据库逻辑迁移解决方案的逻辑迁移技术和迁移过程进行分析,指出迁移过程需要考虑的多种因素。然后,对方案进行具体应用。实践表明该方案具有有效性。
Due to the complexity and difficulty in the existing data migration scenarios, the data migration solution based on Export/Import and data pump technology is given. Firstly, the logical migration technology and the processe of large oracle database logical migration are analyzed, and many factors that should be considered in the migration process are presented. Then apply the scheme specificly. Practices show the solution is effective.
