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)     )   ) initracdg.ora 参数 *.audit_file_dest='/u01/app/oracle/admin/rac/adump' *.audit_trail='db' *.db_recovery_file_dest='+DATA' *.db_recovery_file_dest_size=1024m *.db_unique_name='racdg' *.db_name='rac' *.control_files='+DATA/racdg/CONTROLFILE/control01.ctl','+DATA/racdg/CONTROLFILE/control02.ctl' *.diagnostic_dest='/oracle/app/oracle' *.dispatchers='(PROTOCOL=TCP) (SERVICE=racXDB)' *.fal_server='rac' family:dw_helper.instance_mode='read-only' *.job_queue_processes=0 #*.local_listener='-oraagent-dummy-' *.log_archive_config='DG_CONFIG=(racdg,rac)' *.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=racdg' *.log_archive_dest_2='SERVICE=rac LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=rac' #*.log_archive_dest_state_1='ENABLE' #*.log_archive_dest_state_2='ENABLE' *.log_archive_format='%t_%s_%r.dbf' *.open_cursors=300 *.processes=1000 *.remote_login_passwordfile='exclusive' *.standby_file_management='AUTO' *.undo_tablespace='UNDOTBS1' *.service_names='racdg' *.log_file_name_convert='+DATA/rac/','+DATA/racdg/ONLINELOG/','+DATA/rac/ONLINELOG','+DATA/racdg/ONLINELOG' *.db_file_name_convert='+DATA/rac/','+DATA/racdg/DATAFILE/','+DATA/rac/DATAFILE/','+DATA/racdg/DATAFILE' *.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。
