oracle 测试库搭建,Oracle Study之--通过RMAN克隆测试库
Oracle Study之--通過RMAN克隆測試庫
通過使用數據庫備份，DBA可以在同一服務器或其它服務器上建立副本數據庫。這個副本數據庫可以和主數據庫有相同的名稱(拷貝)或與主數據庫名稱不同(克隆)。ORACLE在數據庫拷貝和數據庫克隆之間惟一不同的是拷貝的數據庫不能更改名稱。使用RMAN的復制數據庫特性，可以從RMAN備份創建一個新的數據庫，并為這個副本數據庫保留已有的數據庫名稱或者賦予新的名稱。
RMAN術語和命令：
A．輔助數據庫(Auxiliary database)：RMAN將目標數據庫復制到該數據庫實例。要創建該數據庫的參數文件、路徑和口令文件。必須在RMAN數據庫復制之前以非加載(NOMOUNT)模式啟動輔助數據庫實例。
B．復制(Duplicate)：從其它數據庫的RMAN備份創建一個新的數據庫。要在RMAN執行復制的位置配置數據庫并啟動Oracle的實例。從RMAN的角度來看，目標數據庫被復制到副本數據庫。
C．設置新名稱(Set newname)：在一個RMAN運行塊內為數據文件設置新的名稱，提供給該參數的文件名稱覆蓋任何該數據文件的輔助數據庫名(用SET AUXNAME)或者輔助數據庫參數(DB_FILE_NAME_CONVERT)。這個新名稱的值只在運行塊內有效。
D．設置輔助名稱(Set auxname)：為數據文件設置輔助名稱，這個輔助名稱將在RMAN會話之間存在。如果不希望以后的RMAN命令中使用這個設置的名稱，則必須將該名稱設置為NULL。
E．日志文件(log file)：可以在Duplicate命令中作用這個關鍵詞，以指定副本數據庫創建的聯機重做日志文件。如果沒有特別指定這個關鍵詞，則RMAN將在輔助參數文件中的LOG_FILE_NAME_CONVERT參數決定的路徑中生成日志文件。如果沒有這個RMAN關鍵詞，而且也沒有設置輔助參數，則RMAN將在目標數據庫同樣的位置創建日志(假設已指定了NOCHECKFILENAME選項)。
F．不檢查文件名(Nocheckfilename)：默認情況下，RMAN將檢查在副本主機上被恢復到主目標數據文件路徑下的數據文件，以確保不會被錯誤地覆蓋。使用該選項可以覆蓋這個默認的操作。這樣就需要手工確保RMAN沒有覆蓋任何已存在的數據文件。應當謹慎使用這個命令，以防止覆蓋數據文件。
在Duplicate命令執行的過程中，RMAN執行了一系列工作。當連接到目標、輔助和或選的目錄數據庫后，RMAN將進行以下操作：
1)根據最近發生的或者是提供的恢復停止點來決定復制操作將使用哪個基本的備份。
2)根據輔助數據庫參數或RMAN設置的命令和選項來決定將數據文件保存在輔助數據庫實例的什么位置。
3)為輔助數據庫讀出備份片或映像拷貝并恢復數據文件。這個RMAN的功能與執行正常的數據庫還原是一樣的。
4)根據恢復停止點將任何增量備份應用于還原數據文件。這個增量方式的應用與用RMAN發布恢復數據庫命令的任務是一樣的。
5)根據恢復停止點從磁盤或備份將所有歸檔日志文件應用于還原數據文件。
6)為輔助數據庫創建新的控制文件。
7)當重新設置聯機重做日志文件時，打開副本數據庫。新的聯機重做日志文件將根據RMAN復制數據庫命令中指定的或者根據轉換的輔助參數文件進行創建。

2、建立pfile 文件
08:59:31 SQL> create pfile from spfile;
File created.
3、建立克隆庫的目錄[oracle@RH4?dbs]$?mkdir?-p?$ORACLE_BASE/admin/clonedb/bdump
[oracle@RH4?dbs]$?mkdir?-p?$ORACLE_BASE/admin/clonedb/cdump
[oracle@RH4?dbs]$?mkdir?-p?$ORACLE_BASE/admin/clonedb/udump
[oracle@RH4?dbs]$?mkdir?-p?$ORACLE_BASE/oradata/clonedb
4、將主庫pfile 拷貝生成clone 庫的pfile，并生成clone庫的口令文件
[oracle@RH4 dbs]$ orapwd file=orapwclonedb.ora password=oracle entries=3;
[oracle@RH4 dbs]$ cp initdb01.ora initclonedb.ora
[oracle@RH4 dbs]$ vi initclonedb.ora將db01?替換為?clonedb，并增加以下內容：
db_file_name_convert?=?("/u01/app/oracle/oradata/db01"?,"/u01/app/oracle/oradata/clonedb")log_file_name_convert?=?("/disk1/oradata/db01","/disk1/oradata/clonedb","/disk2/oradata/db01","/disk2/oradata/clonedb")
5、將clone 庫啟動到nomount[oracle@RH4?dbs]$?export?ORACLE_SID=clonedb
[oracle@RH4?dbs]$?sqlsqlplus?'/as?sysdba'
