環境：
源庫 10.17.80.190
目標庫 10.17.80.189
uid：ictdb

—-rman 異機備份過程———————————
【源庫】
1、準備：開啟歸檔模式

1、SQLPLUS / AS SYSDBA --登入資料庫
2、SQL>archive log list  檢視是否開啟歸檔模式
2、SQL> shutdown immediate; --關閉資料庫
3、SQL>startup mount; --將資料庫啟動到mount 狀態
4、SQL>alter database archivelog; --將資料庫置為歸檔模式
5、SQL>alter database open; --開啟資料庫 
6、SQL>archive log list  檢視
7、SQL>alter system set log_archive_dest_1='location=/opt/oracle/archivelog' scope=spfile;  設定歸檔日誌目錄

--建立資料表(測試用的資料庫)：

    create table mytables (name char(32),sex char(1),age int);
    insert into mytables values('tym','m','24');
    insert into mytables values('tqq','f','25');
    insert into mytables values('add','f','111');
    insert into mytables values('from myoracle','f','0');
    insert into mytables values('from 10.17.80.235','f','0');
 

2、備份：利用rman 備份控制檔案 ,全庫和歸檔日誌;

###CONFIGURE CONTROLFILE AUTOBACKUP ON;
    run{ 
    allocate channel d1 type disk;
    allocate channel d2 type disk;
    crosscheck backup;
    crosscheck archivelog all;
    sql 'alter system archive log current';
    backup database format '/opt/oracle/rmanbackup/dbf/full__%d_%s_%p_%u.bak'
 
;
    sql 'alter system archive log current';
    backup current controlfile format '/opt/oracle/rmanbackup/control/control_%s_%p_%t';
    backup archivelog all format '/opt/oracle/rmanbackup/dbf/archive_%t_%s' delete all input;
    crosscheck backup;
    release channel d2;
    release channel d1;
    }

3、遠端拷貝備份集到目標機

cd /opt/oracle/rmanbackup
    scp -r * oracle@10.17.81.190:/opt/oracle/rmanbackup

【目標庫】

4 、圖形化介面建立跟源庫一樣的例項

    root@oracle# xhost +
    root@oracle# su - oracle
    oracle@oracle$ export DISPLAY=:3.0
    oracle@oracle$ dbca
    然後安裝提示一步一步建立跟源庫一樣的例項

    最後檢查相關目錄是否存在
    配置系統環境 設定 $ORACLE_SID 跟源db的sid 一樣

5、建立密碼檔案: 認證的密碼檔案 (可選)

cd $ORACLE_HOME/bin
orapwd file=$ORACLE_HOME/dbs/orapwictdb password=oracle entries=8
cd $ORACLE_HOME/dbs

6、恢復引數檔案: 設定ORACLE_SID環境變數,設定DBID,在nomount狀態下,恢復引數檔案

RMAN>shutdown immediate;
RMAN>startup nomount;
RMAN>restore spfile to pfile '/opt/oracle/product/11gR1/db/dbs/initictdb.ora' from '/opt/oracle/rmanbackup/control/o1_mf_s_889366833_byf59l5x_.bkp';

7、恢復控制檔案: 設定ORACLE_SID環境變數,設定DBID,在nomount狀態下,恢復控制檔案

RMAN>restore controlfile from '/opt/oracle/rmanbackup/control/o1_mf_s_889366833_byf59l5x_.bkp';

8、註冊備份集

RMAN>startup mount;
RMAN>catalog start with "/opt/oracle/rmanbackup/dbf";
RMAN>catalog start with "/opt/oracle/rmanbackup/control";

9、恢復資料檔案: 設定ORACLE_SID環境變數,設定DBID,在mount 狀態下,恢復資料檔案;

    RMAN>restore database;
    RMAN>recover database;
    RMAN>list incarnation; 
    會提示錯誤
    RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 18 and starting SCN of 7084319
    解決：
    RMAN> run {
      set until scn 7084319 ;
      restore database;
      recover database;
      alter database open resetlogs;
     }

10、檢查資料是否恢復正常；
