随着医院信息化的不断发展,应用负荷的不断增加,服务器超出正常负载能力,医院将面临服务器升级的问题。数据迁移是服务器升级过程中最重要的环节。数据迁移过程中一定要保证数据安全、无损、完整的从旧数据库服务器迁移到新的数据库服务器上。如何能实现将旧数据库服务器上的所有历史数据转换到新的数据库服务器上,并且在数据迁移的过程中,不停用业务核心部门的系统应用。本文就本院HIS服务器升级过程中实现不停用业务核心部门的系统应用下对数据迁移的安全保障实践做一讨论。
With the continuous development of hospital information, application load continues to increase, the server beyond the normal load capacity, the hospital will face the problem of server upgrades. Data migration is the most important part of the server upgrade process. Data migration process must ensure data security, lossless, complete migration from the old database server to the new database server. How to convert all the historical data on the old database server to the new database server and not to disable the system application in the business core during data migration. This article discusses the security of data migration in the HIS server upgrade process in the hospital to achieve non-stop core business applications.
