NBU Linux上oracle單實(shí)例恢復(fù)到單實(shí)例

注意：本文檔操作系統(tǒng)環(huán)境以Linux為主，假設(shè)要恢復(fù)金融數(shù)據(jù)庫(kù)；

本文當(dāng)主要以數(shù)據(jù)庫(kù)恢復(fù)為主,操作系統(tǒng)安裝、數(shù)據(jù)庫(kù)安裝配置和NBU客戶端安裝配置忽略；

要恢復(fù)的數(shù)據(jù)庫(kù)信息：

1. 確定要恢復(fù)的數(shù)據(jù)庫(kù)信息，如果數(shù)據(jù)庫(kù)和操作系統(tǒng)可以正常訪問(wèn)，則可以登錄數(shù)據(jù)庫(kù)和操作系統(tǒng)查看和恢復(fù)信息相關(guān)的信息，如果數(shù)據(jù)庫(kù)甚至是操作系統(tǒng)不可訪問(wèn)，則可以參考《oracle數(shù)據(jù)庫(kù)信息收集》文檔，里面記錄了oracle數(shù)據(jù)庫(kù)恢復(fù)的相關(guān)信息；

2. 為了確保恢復(fù)后的數(shù)據(jù)庫(kù)可以盡快使用，盡量減少應(yīng)用程序的修改，恢復(fù)完以后修改主機(jī)IP地址和原數(shù)據(jù)庫(kù)地址保持一致；

準(zhǔn)備環(huán)境：

1. 根據(jù)《oracle數(shù)據(jù)庫(kù)信息收集》文檔，安裝操作系統(tǒng)和數(shù)據(jù)庫(kù)軟件，其中操作系統(tǒng)的版本盡量相同，數(shù)據(jù)庫(kù)版本則需要一致；

2. 根據(jù)《oracle數(shù)據(jù)庫(kù)信息收集》文檔，掛載合適的存儲(chǔ)，主要是存儲(chǔ)的大小，所掛載的存儲(chǔ)不可小于要恢復(fù)的數(shù)據(jù)庫(kù)總?cè)萘看笮?，并配置合適的ASM磁盤(pán)組，磁盤(pán)組的大小和名稱(chēng)建議原來(lái)一樣，磁盤(pán)組的容量可以大于原磁盤(pán)組；

3. 在客戶端安裝好NBU client，并保證通過(guò)NBU client可以正常訪問(wèn)備份文件；

恢復(fù)步驟：

恢復(fù)文件說(shuō)明:

在操作系統(tǒng)上執(zhí)行如下命令：

/usr/openv/netbackup/bin/bplist -C fxzmd -t 4 -l -R /

列出數(shù)據(jù)庫(kù)備份信息，部分信息如下：

最后重啟下數(shù)據(jù)庫(kù)，恢復(fù)完成；

數(shù)據(jù)庫(kù)正?；謴?fù)后配置：

修改主機(jī)的IP地址：

啟動(dòng)監(jiān)聽(tīng)：

lsnrctl start

把spfile從文件系統(tǒng)放到ASM磁盤(pán)組中：

1. 創(chuàng)建pfile：

SQL> create pfile='/home/oracle/initfxzmd.ora' from spfile;

2. 創(chuàng)建spfile：

SQL> create spfile='+DGROUP1' from pfile='/home/oracle/initfxzmd.ora';

3. 修改pfile：

在$ORACLE_HOME/dbs下創(chuàng)建initfxzmd.ora文件，內(nèi)容如下：

SPFILE='+DGROUP1/FXZMD/PARAMETERFILE/spfile.259.856714109'

4. 刪除$ORACLE_HOME/dbs下的spfile，重啟數(shù)據(jù)庫(kù)：

SQL> show parameter spfile;

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

spfile string +DGROUP1/fxzmd/parameterfile/spfile.259.856714109

修改成功，spfile成功放入ASM磁盤(pán)組中；

5. 為了才dbca中能正?？吹交謴?fù)過(guò)來(lái)的數(shù)據(jù)庫(kù)，需要在

/etc/oratab 文件結(jié)尾添加如下內(nèi)容：
fxzmd:/app/oracle/product/10.2/db_1:N

6. 最后做一個(gè)數(shù)據(jù)庫(kù)全備！
