你这个问题转化的时候会报一个错：
SQL> alter database commit to switchover to primary;
alter database commit to switchover to primary
*
ERROR at line 1:
ORA-16139: media recovery required
然后介质恢复后
SQL> alter database recover managed standby database disconnect from session;
Database altered.
在做转化就好了
SQL> alter database commit to switchover to primary;
Database altered.
