Oracle 11gR2 使用 rman 達到 database 異機還原的目標

2013-07-13 02:13

 

1. 環境介紹 

Source DB : SIPDB   

Destination DB : SIPDB2  

SID : orcl

 

 

2.進行 Source DB 備份作業

SIPDB 要開啟 Archive Log mode

 
[oracle@SIPDB ~]$ sqlplus / as sysdba
SQL> shutdown immediate;

SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;

SQL> archive log list
Database log mode                   Archive Mode
Automatic archival                    Enabled
Archive destination                   USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence       6346
Next log sequence to archive     6348
Current log sequence                6348
 

 

在 SIPDB 建立 /data/backup 資料夾來存放備份檔案，並設定 oracle 為其 owner

 

[root@SIPDB /]# mkdir -p /data/backup/
 
[root@SIPDB /]# chown -R oracle.dba /data/backup/

 

編寫 rman 備份 script ，其內容如下

[oracle@SIPDB ~]$ cat backup_db.rman
run {
 allocate channel c1 type disk;
 allocate channel c2 type disk;
 allocate channel c3 type disk;
 allocate channel c4 type disk;
 allocate channel c5 type disk;
 backup database format '/data/backup/%d_%U_%n_%T' ;
 backup archivelog all delete all input format '/data/backup/ARC_%U_%n_%T';
 backup current controlfile format '/data/backup/%d_control_%U_%n_%T.ctl';
     }
 
#########################################
 
%d       資料庫名稱
%u       一個八個字符的名稱代表備份集與創建時間
%n       資料庫名稱，向右填補到最大八個字符
%T       年月日格式(YYYYMMDD)
 
#########################################
 
用 oracle 身份執行 rman 備份
 
[oracle@SIPDB ~]$ rman target / nocatalog @backup_db.rman

這時備份檔已經存在 /data/backup/ 了

3. 進行 Destination DB 還原作業

先在 Destination DB 主機上安裝 Oracle 11gR2，但不用建立資料庫
 
把 Source DB 的 /data/backup 中的檔案複製到 Destination DB
[oracle@SIPDB ~]$ scp -r /data/backup/ SIPDB2:/data/backup/
ORCL_2eoejq8p_1_1_ORCLxxxx_20130713                                       100%  628MB  25.1MB/s   00:25

ORCL_2doejq8p_1_1_ORCLxxxx_20130713                                       100%  725MB  25.9MB/s   00:28

複製 SIPDB  spfileorcl.ora、orapworcl 到 SIPDB2 $ORACLE_HOME/$ORACLE_HOME/dbs/ 下

[oracle@SIPDB dbs]$ scp spfileorcl.ora SIPDB2:/opt/u01/app/oracle/product/11.2.0/dbhome_1/dbs/spfileorcl.ora           100% 3584     3.5KB/s   00:00

100% 1536     1.5KB/s   00:00
 

 

複製 SIPDB  listener.ora、tnsnames.ora 到 SIPDB2 $ORACLE_HOME/$ORACLE_HOME/network/admin/ 下

[oracle@SIPDB admin]$ scp listener.ora SIPDB2:/opt/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora                                                         100%  378     0.4KB/s   00:00
[oracle@SIPDB admin]$ scp tnsnames.ora SIPDB2:/opt/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora      
 
#########################################
 
HOST 要改成自己的Hostname  (HOST = SIPDB2)

4. 進行 Destination DB 還原作業

    

在 SIPDB2 中建立 $ORACLE_BASE/flash_recovery_area 目錄

[oracle@SIPDB2 ~]$ mkdir $ORACLE_BASE/flash_recovery_area
 
將 DB 開到 nomount mode
[oracle@SIPDB2 ~]$ sqlplus / as sysdba

用 rman 回覆 control file
