NBU Linux上oracle單實例恢復到單實例

注意：本文檔操做系統環境以Linux爲主，假設要恢復金融數據庫；

本文當主要以數據庫恢復爲主,操做系統安裝、數據庫安裝配置和NBU客戶端安裝配置忽略；

要恢復的數據庫信息：

1. 肯定要恢復的數據庫信息，若是數據庫和操做系統能夠正常訪問，則能夠登陸數據庫和操做系統查看和恢復信息相關的信息，若是數據庫甚至是操做系統不可訪問，則能夠參考《oracle數據庫信息收集》文檔，裏面記錄了oracle數據庫恢復的相關信息；

2. 爲了確保恢復後的數據庫能夠儘快使用，儘可能減小應用程序的修改，恢復完之後修改主機IP地址和原數據庫地址保持一致；

準備環境：

1. 根據《oracle數據庫信息收集》文檔，安裝操做系統和數據庫軟件，其中操做系統的版本儘可能相同，數據庫版本則須要一致；

2. 根據《oracle數據庫信息收集》文檔，掛載合適的存儲，主要是存儲的大小，所掛載的存儲不可小於要恢復的數據庫總容量大小，並配置合適的ASM磁盤組，磁盤組的大小和名稱建議原來同樣，磁盤組的容量能夠大於原磁盤組；

3. 在客戶端安裝好NBU client，並保證經過NBU client能夠正常訪問備份文件；

恢復步驟：

恢復文件說明:

在操做系統上執行以下命令：

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

列出數據庫備份信息，部分信息以下：

Spfile

建立pfile 修改pfile文件：

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

File created.

編輯pfile：

根據$ORACLE_BASE、$ORACLE_HOME建立相應的目錄：

mkdir –p /app/oracle/admin/fxzmd/adump

mkdir –p /app/oracle/admin/fxzmd/bdump

mkdir –p /app/oracle/admin/fxzmd/cdump

mkdir –p /app/oracle/admin/fxzmd/udump

用修改過的pfile 建立spfile：

關閉數據庫：

SQL> shutdown immediate

ORA-01507: database not mounted

ORACLE instance shut down.

用新的pfile啓動數據庫到nomount：

SQL> startup nomount pfile='/home/oracle/initfxzmd.ora';

最後重啓下數據庫，恢復完成；

數據庫正常恢復後配置：

修改主機的IP地址：

啓動監聽：

lsnrctl start

把spfile從文件系統放到ASM磁盤組中：

1. 建立pfile：

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

2. 建立spfile：

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

3. 修改pfile：

在$ORACLE_HOME/dbs下建立initfxzmd.ora文件，內容以下：

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

4. 刪除$ORACLE_HOME/dbs下的spfile，重啓數據庫：

SQL> show parameter spfile;

NAME TYPE VALUE

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

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

修改爲功，spfile成功放入ASM磁盤組中；

5. 爲了才dbca中能正常看到恢復過來的數據庫，須要在

/etc/oratab 文件結尾添加以下內容：
fxzmd:/app/oracle/product/10.2/db_1:N

6. 最後作一個數據庫全備！
