摘 要: | 为了保证主机系统中数据运行的安全可靠,建立双机热备份的两套相对独立又完全相同的系统,在IBMAS/500主机实现了实时备份的功能,在生产系统损坏时把用户及时切换到备份系统上继续工作,保证了生产数据的安全。同时对双机热备份系统的原理及功能做以详细介绍,该系统在辽化“二期”工程上得到应用。

Abstract: | In order to guarantee the security and reliability of data running in mainframe, two on-line back-up systems which are completely the same but relatively independent each other have heen established on duplicating computers. The on-line back-up function has been implemented on IBM AS/500. When production system is out of order switching the users into back-up system on time to continue working ensures the security of production data. The principle and function of on-line back-up systems on duplicating computers have discusstd in detail as well. This system has been applied to the second phase of Liayang petrochemical project. |
