Linux oracle 11g关机后长时间启动中止

我的意思是用

shutdown immediate

关闭数据库，但它在20分钟后还没有完成。然后我用

shutdown abort

关闭它。 启动时，需要3-4个小时才能将

装载

状态更改为

打开

。 下面是alter.log：

此问题与磁盘有关吗？

关闭后，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.大量的数据块需要恢复，因此oracle将向前滚动 重做以恢复损坏的块。 2.磁盘性能

对于第一种方法，您可以通过设置快速启动\u mttr\u目标参数来减少它，或者您可以根据您的系统经验将重做日志文件大小设置为正确的值。

对于第二种情况，您应该使用性能更好的磁盘。

这意味着在您立即关闭时发生了一个巨大的事务，通过执行关闭中止，您只是在启动时推迟了回滚，并解释了启动时间为何如此之长。在这种情况下，文档是可用的：
