摘要
常规的医院Oracle数据库容灾备份方法数据恢复时间过长,因此设计一种全新的医院Oracle数据库容灾备份方法。先以成本和时间有效的容灾系统模型体系(Cost and Time Effective Disaster Recovery System,ETDRS)为基础,结合遗传算法选取了有效的Oracle容灾备份编码例子,再根据智能合约构建了有效的数据库容灾备份平台,从而实现了Oracle数据库容灾备份。实验结果表明,设计方法在不同数量数据块下的数据恢复时间均较短,备份效果较好,有一定的应用价值。
The conventional hospital Oracle database disaster recovery backup method takes too long to recover the data,so a new hospital Oracle database disaster recovery backup method is designed.That is,based on the Cost and Time Effective Disaster Recovery System(ETDRS)model system,an effective Oracle disaster recovery coding example is selected by combining genetic algorithm.Then an effective database disaster recovery platform is constructed according to the smart contract,so that the Oracle database disaster recovery is realized.The experimental results show that the designed method has a shorter data recovery time and better backup effect under different number of data blocks,which has some application value.
