关机中止后oracle 11g长时间启动

Question

我的意思是用shutdown immediate关闭数据库，但是在20min.Then之后它还没有完成--我使用shutdown abort关闭它。当我开始时，需要3-4个小时才能将mount状态更改为open。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

关闭后，中止数据库将在打开数据库之前进行崩溃恢复。时间相关1.块的数量需要恢复，因此甲骨文将前滚重做以恢复损坏的块。2.磁盘的性能

对于第一种方法，您可以通过设置fast_start_mttr_target参数来减少它，或者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。对于第二个问题，您应该使用性能更好的磁盘。
