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.
