Question

我的意思是使用shutdown immediate关闭数据库，但在20分钟后它没有完成。然后我使用shutdown abort关闭它。当我开始时，将mount状态更改为open需要3-4个小时。下面是alter.log：

ORA-01155: the database is being opened, closed, mounted or dismounted

这个问题与磁盘有关吗？

Answer 1

关闭中止数据库将在打开数据库之前执行崩溃恢复。时间关系 1.块的体积需要恢复，因为oracle将向前滚动重做以恢复损坏的块。 2.磁盘性能

对于第一个，您可以通过设置 fast_start_mttr_target 参数来减少它，或者您可以根据您的系统体验将重做日志文件大小设置为正确的值。对于第二个，您应该使用性能更好的磁盘。

关机中止后oracle 11g长启动
