cat 主庫 check unique lin 創建 庫文件 lgwr err

oracle 11.2.0.4 運行以下腳本，使用活動數據庫復制技術創建dataguard備庫報錯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‘
;
}

報錯信息如下：

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恢復時不指定 nofilenamecheck 參數，則在數據文件相同文件名恢復時會出現RMAN-005001錯誤，當主庫，備庫的數據庫文件目錄是一樣的時候，必須使用 nofilenamecheck參數告訴rman主庫和被創建的備份庫擁有一樣的文件目錄和文件名。
修改腳本如下，再次嘗試創建備庫成功：

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‘
;
}
