关于控制文件转储后的trace文件中'Controlfile Checkpointed at scn'的含义

 Controlfile Checkpointed at scn:  0x0000.0006c3dc 05/14/2015 05:44:54

这个点从DSI中得到的信息如下：

Controlfile Checkpoint at SCN: It is updated after every checkpoint (may it be 
 tablespace, thread, or database) and is always greater than or equal to the database 
 checkpoint when the database is open.
