SQL Server High-availability scenarios Scenario One:asynchronous Mirror + AliasProgram IntroductionThe database server configures an asynchronous mirroring relationship, and the program client connection string configures the alias connection.1. Create an alias in the SQL Server client configuration, replacing the server name or IP address with an alias in the client's connection string settings.2. Write a utility that updates the alias when mirroring

The reliability of the computer system is measured by the average time of no fault (MTTF), that is, the average time the computer system can run normally before a fault occurs. The higher the system reliability, the longer the average fault-free time. Maintainability is measured by the mean service time MTTR), that is, the average time it takes to repair and restore the system to normal after a fault occurs. The better the maintainability of the system, the shorter the average maintenance time.
