oracle 测试库搭建,Oracle Study之--通过RMAN克隆测试库
Oracle Study之--通過(guò)RMAN克隆測(cè)試庫(kù)
通過(guò)使用數(shù)據(jù)庫(kù)備份，DBA可以在同一服務(wù)器或其它服務(wù)器上建立副本數(shù)據(jù)庫(kù)。這個(gè)副本數(shù)據(jù)庫(kù)可以和主數(shù)據(jù)庫(kù)有相同的名稱(拷貝)或與主數(shù)據(jù)庫(kù)名稱不同(克隆)。ORACLE在數(shù)據(jù)庫(kù)拷貝和數(shù)據(jù)庫(kù)克隆之間惟一不同的是拷貝的數(shù)據(jù)庫(kù)不能更改名稱。使用RMAN的復(fù)制數(shù)據(jù)庫(kù)特性，可以從RMAN備份創(chuàng)建一個(gè)新的數(shù)據(jù)庫(kù)，并為這個(gè)副本數(shù)據(jù)庫(kù)保留已有的數(shù)據(jù)庫(kù)名稱或者賦予新的名稱。
RMAN術(shù)語(yǔ)和命令：
A．輔助數(shù)據(jù)庫(kù)(Auxiliary database)：RMAN將目標(biāo)數(shù)據(jù)庫(kù)復(fù)制到該數(shù)據(jù)庫(kù)實(shí)例。要?jiǎng)?chuàng)建該數(shù)據(jù)庫(kù)的參數(shù)文件、路徑和口令文件。必須在RMAN數(shù)據(jù)庫(kù)復(fù)制之前以非加載(NOMOUNT)模式啟動(dòng)輔助數(shù)據(jù)庫(kù)實(shí)例。
B．復(fù)制(Duplicate)：從其它數(shù)據(jù)庫(kù)的RMAN備份創(chuàng)建一個(gè)新的數(shù)據(jù)庫(kù)。要在RMAN執(zhí)行復(fù)制的位置配置數(shù)據(jù)庫(kù)并啟動(dòng)Oracle的實(shí)例。從RMAN的角度來(lái)看，目標(biāo)數(shù)據(jù)庫(kù)被復(fù)制到副本數(shù)據(jù)庫(kù)。
C．設(shè)置新名稱(Set newname)：在一個(gè)RMAN運(yùn)行塊內(nèi)為數(shù)據(jù)文件設(shè)置新的名稱，提供給該參數(shù)的文件名稱覆蓋任何該數(shù)據(jù)文件的輔助數(shù)據(jù)庫(kù)名(用SET AUXNAME)或者輔助數(shù)據(jù)庫(kù)參數(shù)(DB_FILE_NAME_CONVERT)。這個(gè)新名稱的值只在運(yùn)行塊內(nèi)有效。
D．設(shè)置輔助名稱(Set auxname)：為數(shù)據(jù)文件設(shè)置輔助名稱，這個(gè)輔助名稱將在RMAN會(huì)話之間存在。如果不希望以后的RMAN命令中使用這個(gè)設(shè)置的名稱，則必須將該名稱設(shè)置為NULL。
E．日志文件(log file)：可以在Duplicate命令中作用這個(gè)關(guān)鍵詞，以指定副本數(shù)據(jù)庫(kù)創(chuàng)建的聯(lián)機(jī)重做日志文件。如果沒(méi)有特別指定這個(gè)關(guān)鍵詞，則RMAN將在輔助參數(shù)文件中的LOG_FILE_NAME_CONVERT參數(shù)決定的路徑中生成日志文件。如果沒(méi)有這個(gè)RMAN關(guān)鍵詞，而且也沒(méi)有設(shè)置輔助參數(shù)，則RMAN將在目標(biāo)數(shù)據(jù)庫(kù)同樣的位置創(chuàng)建日志(假設(shè)已指定了NOCHECKFILENAME選項(xiàng))。
F．不檢查文件名(Nocheckfilename)：默認(rèn)情況下，RMAN將檢查在副本主機(jī)上被恢復(fù)到主目標(biāo)數(shù)據(jù)文件路徑下的數(shù)據(jù)文件，以確保不會(huì)被錯(cuò)誤地覆蓋。使用該選項(xiàng)可以覆蓋這個(gè)默認(rèn)的操作。這樣就需要手工確保RMAN沒(méi)有覆蓋任何已存在的數(shù)據(jù)文件。應(yīng)當(dāng)謹(jǐn)慎使用這個(gè)命令，以防止覆蓋數(shù)據(jù)文件。
在Duplicate命令執(zhí)行的過(guò)程中，RMAN執(zhí)行了一系列工作。當(dāng)連接到目標(biāo)、輔助和或選的目錄數(shù)據(jù)庫(kù)后，RMAN將進(jìn)行以下操作：
1)根據(jù)最近發(fā)生的或者是提供的恢復(fù)停止點(diǎn)來(lái)決定復(fù)制操作將使用哪個(gè)基本的備份。
2)根據(jù)輔助數(shù)據(jù)庫(kù)參數(shù)或RMAN設(shè)置的命令和選項(xiàng)來(lái)決定將數(shù)據(jù)文件保存在輔助數(shù)據(jù)庫(kù)實(shí)例的什么位置。
3)為輔助數(shù)據(jù)庫(kù)讀出備份片或映像拷貝并恢復(fù)數(shù)據(jù)文件。這個(gè)RMAN的功能與執(zhí)行正常的數(shù)據(jù)庫(kù)還原是一樣的。
4)根據(jù)恢復(fù)停止點(diǎn)將任何增量備份應(yīng)用于還原數(shù)據(jù)文件。這個(gè)增量方式的應(yīng)用與用RMAN發(fā)布恢復(fù)數(shù)據(jù)庫(kù)命令的任務(wù)是一樣的。
5)根據(jù)恢復(fù)停止點(diǎn)從磁盤或備份將所有歸檔日志文件應(yīng)用于還原數(shù)據(jù)文件。
6)為輔助數(shù)據(jù)庫(kù)創(chuàng)建新的控制文件。
7)當(dāng)重新設(shè)置聯(lián)機(jī)重做日志文件時(shí)，打開(kāi)副本數(shù)據(jù)庫(kù)。新的聯(lián)機(jī)重做日志文件將根據(jù)RMAN復(fù)制數(shù)據(jù)庫(kù)命令中指定的或者根據(jù)轉(zhuǎn)換的輔助參數(shù)文件進(jìn)行創(chuàng)建。
