Oracle linux 7.5安装oracle 12c dg一直提示ORA-01017

这几天在生产环境安装12c dg很不顺利，参照以前6.X装12c dg，参数什么的一样，可一直提示ORA-01017，listener.ora/tnsnames.ora/设置没啥问题。

如下为后续在自己备库测试环境搭建参数：

listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = racdg)

      (ORACLE_HOME = /u01/app/12.2.0/grid)

      (SID_NAME = racdg)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = racdg)

      (ORACLE_HOME = /u01/app/12.2.0/grid)

      (SID_NAME = rac)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = rac)

      (ORACLE_HOME = /u01/app/12.2.0/grid)

      (SID_NAME = rac)

    )

  )

tnsnames.ora

RAC =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.168)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = rac)

      (UR=A)

    )

  )

RACdg =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.188)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = racdg)

      (UR=A)

    )

  )

*.local_listener='-oraagent-dummy-'  这个参数我不屏蔽，一直会提示 ORA-01017: invalid username/password

我屏蔽了这个参数后，再次重启数据库，问题解决。  实在有些纳闷，这个参数不是管控动态注册的吗？而且以前其他版本这个参数我都没有去屏蔽都没问题。不知道有没有其他朋友碰到类似问题，还请解答下。
