论坛上一个朋友的帖子，自己使用sql_trace 跟踪了dbms_logmnr.end_logmnr的后台执行过程。。

自己做了一下。。关键部分如下：
=====================
PARSING IN CURSOR #1 len=137 dep=1 uid=0 ct=47 lid=0 tim=10262706437 hv=4235843831 ad='30e2795c' sqlid='a603td7y7mq7r'

END OF STMT

=====================
可以看出 执行了dbms_logmnr.end_logmnr之后，数据库清除与logminr有关的动态性能视图所包含的事务变化内容。。
