报这个错误
ORA-19527: physical standby redo log must be renamed
ORA-00312: online log 7 thread 0: '/u01/app/oracle/oradata/PD1/standby07.log'
该告警的处理参考文章：https://blogs.oracle.com/Database4CN/entry/11g_%E6%96%B0%E7%89%B9%E6%80%A7_active_database_duplication1
解决方法：
在主备数据库设置LOG_FILE_NAME_CONVERT参数，即使参数的两个值相同也需要设置。例如：
LOG_FILE_NAME_CONVERT='/u01/app/oracle/oradata/PD1/','/u01/app/oracle/oradata/PD1/'，
该参数需要重启实例才能生效，之后清除备用数据库，
在备库重新执行duplicate操作即可。
/*******************************************************************************
*******************************************************************************/
将备库置于active dataguard模式下,duplicate for standby 完成后，备库处于 mount 状态，需要手动操作进行恢复操作。
