一种跨中心系统的清算文件灾备恢复方法

本文提出了一种在异地双活系统架构中本地系统故障后在异地恢复金融交易清算文件的方法,可通过按文件生成场次备份生成清算文件所需的文件生成条件表,分场景恢复清算文件。在备份的条件表是故障前最新数据时,在异地可直接恢复控制信息,并接管文件生成业务;在备份的条件表不是所需的最新数据时,可以恢复前一场次的条件表,同时利用交易主键文件勾兑交易数据,能在异地及时补生成已丢失或还未来得及生成的清算文件。同时针对清算文件生成有多个场次的特点,灾备恢复采取了参数配置方式,易扩展。

A Clearing File Recovery Method in Cross-center System

This paper presents a clearing file recovery method in another center of a cross-center financial transaction system when current running center is out of service. It can recover clearing files in different scenes using file producing condition tables those are backed up according to files producing batch. Compared to existing method, it can use less resource of software and hardware without file data missing, and in order to reduce the workload of staff, this paper also provides a disaster recovery toolkit that is parameter configurable and highly extensible.
