唐SIR：
   切换主备库的时候，出现切换成功，但是关闭主库失败，如下所示：
   提示没有权限关闭原主库，这可能是什么原因导致的？
   DGMGRL> switchover to dorcl188;
   Performing switchover NOW, please wait...
   New primary database "dorcl188" is opening...
   Operation requires shutdown of instance "orcl188" on database "orcl188"
   Shutting down instance "orcl188"...
   ORA-01031: insufficient privileges
   Warning: You are no longer connected to ORACLE.
   Please complete the following steps to finish switchover:
        shut down instance "orcl188" of database "orcl188"
        start up and mount instance "orcl188" of database "orcl188"

  双向连接 sys/oracle_4U@orcl188 以及 sys/oracle_4U@dorcl188 都是没问题的
  现在每次切换，都要手动去关闭重启新的备库（原主库）
