RMAN複製資料庫（四）
使用set newname命令轉換檔名
這種方法是使用set newname命令來對複製的資料檔案進行重新命名，使用logfile子句來指定聯機重做日誌的名稱和大小。
1.建立輔助例項的密碼檔案(這裡輔助例項名為dup)
[oracle@jingyong1 dbs]$ orapwd file=/u01/app/oracle/product/10.2.0/db/dbs/orapwdup password=oracle entries=10; [oracle@jingyong1 dbs]$ ls -lrt -rw-r----- 1 oracle oinstall 2560 Mar 24 14:47 orapwdup
2.建立輔助例項網路連線,修改監聽檔案，使用靜態監聽來監聽輔助例項
[oracle@jingyong1 admin]$ vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = dup)
(ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.11)(PORT = 1521))
)
)
給輔助例項增加網路服務名
[oracle@jingyong1 admin]$ vi tnsnames.ora
dup=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =dup)
(UR=A)
)
)
測試網路連線
[oracle@jingyong1 admin]$ export ORACLE_SID=dup [oracle@jingyong1 admin]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 14:57:08 2015 Copyright (c) 1982, 2010, Oracle. All Rights Reserved. SQL> conn sys/oracle@dup as sysdba Connected to an idle instance.
3.建立輔助例項的引數檔案
[oracle@jingyong1 dbs]$ vi initdup.ora db_name=dup db_unique_name=dup control_files= /u01/app/oracle/oradata/test/control01.ctl remote_login_passwordfile=exclusive compatible = 10.2.0.5.0 db_block_size=8192 sga_target=160M sga_max_size=160M pga_aggregate_target=16M [oracle@jingyong1 dbs]$ export ORACLE_SID=dup [oracle@jingyong1 dbs]$ sqlplus / as sysdba SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 21:13:44 2015 Copyright (c) 1982, 2010, Oracle.

4.啟動輔助例項
[oracle@jingyong1 dbs]$ export ORACLE_SID=dup

這裡一定要斷開啟動輔助例項的會話否則在執行復制操作時會出現如下錯誤 ：

在目標主機(執行被複制資料庫的主機）配置輔助例項的網路服務名
[oracle@oracle11g admin]$ vi tnsnames.ora

6.確保有需要的備份和歸檔重做日誌對目標資料庫（被複制的資料庫）進行備份（包含資料檔案和歸檔重做日誌）
[oracle@oracle11g admin]$ export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'

7.執行duplicate命令，如果沒有配置自動通道，那麼至少手動分配一個輔助例項。如果需要的話使用logfile子句將重做日誌的名稱與數量可以設定為與目標資料庫一樣。為複製資料庫的資料檔案指定新的檔名。如果是使用PFILE引數檔案啟動輔助例項需要指定file引數檔案，且pfile引數檔案必須儲存在執行RMAN執行復制的主機上。這裡輔助例項使用SPFILE引數檔案來啟動，並使用自動通道:
