Persistence of Automatically Tuned Values (77)

原创 IT综合 作者:tsinglee 时间:2007-10-23 11:22:56 0 删除 编辑

Oracle Database remembers the sizes of the automatically tuned components across
instance shutdowns if you are using a server parameter file (SPFILE). As a result, the
system does need to learn the characteristics of the workload again each time an
instance is started. It can begin with information from the past instance and continue
evaluating workload where it left off at the last shutdown.

Oracle数据库能记住上次实例关闭时各动态调整组件的值 ,前提条件是使用了spfile .
so , 当实例启动时 , 系统不需要再计算workload , 而可以继续评估上次实例关闭时的workload
