大家好，我是讯享网，很高兴认识大家。

首先说下测试环境：单实例DG，数据库版本为11.2.0.1.0，db_name='TEST'，DB_UNIQUE_NAME=TEST(主备库都是TEST)

主库和备库可以正常同步，做ddl、ddm操作都可以同步，但是我查看归档日志的时候备库比主库多一个归档日志，然后我把主库关掉，那个备库多出来的归档日志就没了。

后来我做主备切换，发现不能切换，下面是我的配置方法，以及日志

主库归档日志：

备库归档日志：(红色表示多余的归档日志，把主库挂掉，就没了)

遇到这种情况，应该怎么做，我在网上查了一下，网上一般说的都是备库有归档日志没有应用，或者主库有归档没有传过去，但是和我遇到的问题还是有点区别，我这边是可以正常传归档，但是备库比主库多了一组。
