SQLSERVER数据库优化配置

SQL Server开启READ_COMMITTED_SNAPSHOT
--查询数据库状态
select name,user_access,user_access_desc,
    snapshot_isolation_state,snapshot_isolation_state_desc,
    is_read_committed_snapshot_on
from sys.databases
 
--设置数据库为SINGLE_USER模式,减少锁定时间
ALTER DATABASE dbname SET SINGLE_USER WITH ROLLBACK IMMEDIATE
ALTER DATABASE dbname SET ALLOW_SNAPSHOT_ISOLATION ON
ALTER DATABASE dbname SET READ_COMMITTED_SNAPSHOT ON
ALTER DATABASE dbname SET MULTI_USER
