实验第33步：

下面来验证：

节选实例1上的/u01/app/oracle/admin/RDBA/udump/rdba1_ora_18378.trc：

trace文件已经说明：实例1重新夺回了对象52533所有的块的mastership。

select*from  myviewwhere"MASTER_Instance"=2 ;

无输出。这就对了，因为都被实例1master了。

DRM为4+1=5，验证了此刻又发生了一次Remaster(第3次Remaster)。

再验证：

进入实例1的/u01/app/oracle/admin/RDBA/bdump:

执行：grep-r"pkey  52533"./

输出：

进入实例2的/u01/app/oracle/admin/RDBA/bdump:
