RMANRMAN-05001: auxiliary filename conflicts with the target database

Posted 2020-09-25 ChavinKing

oracle 11.2.0.4 运行以下脚本，使用活动数据库复制技术创建dataguard备库报错rman-005001：

run{
duplicate target database
for standby
from active database
spfile
     set db_unique_name=‘dbkingstd‘
     set log_file_name_convert ‘/u01/app/oracle/oradata/dbking‘,‘/u01/app/oracle/oradata/dbking‘
     set db_file_name_convert ‘/u01/app/oracle/oradata/dbking‘,‘/u01/app/oracle/oradata/dbking‘
     set control_files=‘/u01/app/oracle/oradata/dbking/control.ctl‘
     set log_archive_dest_2=‘service=dbkingpri lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=dbkingpri‘
     set fal_client=‘dbkingstd‘
     set fal_server=‘dbkingpri‘
;
}

 

报错信息如下：

 

RMAN-05538: WARNING: implicitly using DB_FILE_NAME_CONVERT
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-05001: auxiliary file name /u01/app/oracle/oradata/dbking/system01.dbf conflicts with a file used by the target database

原因：如果在RMAN恢复时不指定 nofilenamecheck 参数，则在数据文件相同文件名恢复时会出现RMAN-005001错误，当主库，备库的数据库文件目录是一样的时候，必须使用 nofilenamecheck参数告诉rman主库和被创建的备份库拥有一样的文件目录和文件名。
修改脚本如下，再次尝试创建备库成功：

 

run{
duplicate target database
for standby nofilenamecheck
from active database
spfile
     set db_unique_name=‘dbkingstd‘
     set log_file_name_convert ‘/u01/app/oracle/oradata/dbking‘,‘/u01/app/oracle/oradata/dbking‘
     set db_file_name_convert ‘/u01/app/oracle/oradata/dbking‘,‘/u01/app/oracle/oradata/dbking‘
     set control_files=‘/u01/app/oracle/oradata/dbking/control.ctl‘
     set log_archive_dest_2=‘service=dbkingpri lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=dbkingpri‘
     set fal_client=‘dbkingstd‘
     set fal_server=‘dbkingpri‘
;
}
