Oracle11gR2使用RMAN duplicate複制資料庫——Backup-based database duplicate

本執行個體測試ORACLE 11g使用rman複制資料庫。11g的RMAN duplicate 可以通過Active database duplicate和Backup-based duplicate兩種方法實作。這裡的測試使用的是Backup-based duplicate。

    1、舊庫或網絡不可用，但是有備份

實驗環境：

target db：

ip 192.168.56.10

oracle_sid=mydb

oracle_version=11.2.0.3

auxiliary db：

ip 192.168.56.150

oracle_sid=oradu

1、備份target db

2、複制參數檔案和建立密碼檔案

--必須保持target DB和auxiliary DB的密碼一緻。這裡我直接把target db的密碼檔案複制到auxiliary db對應的目錄下

--target db上執行

[oracle@localhost ~]$ cd $ORACLE_HOME/dbs

[oracle@localhost dbs]$ scp orapwmydb [email protected]:/home/oracle

[email protected]'s password: 

orapwmydb                                     100% 1536     1.5KB/s   00:00    

[oracle@localhost dbs]$ scp initmydb.ora [email protected]:/home/oracle

initmydb.ora                                  100%  193     0.2KB/s   00:00    

3、把舊機器的備份複制到新機器上的對應目錄

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/34r0vd8l_1_1 [email protected]:/home/oracle/bak

34r0vd8l_1_1                                  100% 5457KB   5.3MB/s   00:00    

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/35r0vd8m_1_1 [email protected]:/home/oracle/bak

35r0vd8m_1_1                                  100% 1049MB  15.0MB/s   01:10    

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/36r0vdad_1_1 [email protected]:/home/oracle/bak

36r0vdad_1_1                                  100% 9952KB   9.7MB/s   00:00    

[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/37r0vdag_1_1 [email protected]:/home/oracle/bak

37r0vdag_1_1                                  100%   10KB  10.0KB/s   00:00    

4、更改密碼檔案、參數檔案的檔案名和參數檔案中的對應的執行個體名(執行個體名不變時不需要執行),

把目錄轉換參數加入參數檔案中(執行個體名、目錄不變時不需要)

本實驗中更新執行個體名為oradu

[oracle@localhost ~]$ mv initmydb.ora initoradu.ora

[oracle@localhost ~]$ mv orapwmydb orapworadu

vi initoradu.ora把所有的舊執行個體名mydb改為oradu，并加入轉換參數

db_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')

log_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')

建立目錄

mkdir -p /u01/app/oracle/oradata/oradu/

不改變執行個體名隻需要建立目錄

mkdir -p /u01/app/oracle/oradata/mydb/

移動參數檔案和密碼檔案到預設目錄中/u01/app/oracle/product/11.2.0/db/dbs/

[oracle@localhost ~]$ mv initoradu.ora /u01/app/oracle/product/11.2.0/db/dbs/

[oracle@localhost ~]$ mv orapworadu /u01/app/oracle/product/11.2.0/db/dbs/

5、啟動到nomount

[oracle@localhost ~]$ export ORACLE_SID=oradu

[oracle@localhost ~]$ sqlplus / as sysdba
