一.主庫與從庫的oracle版本必須一致﹐主庫必須設定為歸檔模式(從庫安裝oracle並建庫)
二.強制主庫為logging狀態
Alter database force logging;

三.在主庫與從庫中同時生成密碼檔案
以oracle使用者登陸
$rm $ORACLE_HOME/dbs/orapw$ORACLE_SID
$orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle entries=4

或

wmrac01$pwd
/u01/product/oracle/11.2.0/db_1/dbs
wmrac01$ll
total 21084
-rw-rw---- 1 oracle asmadmin     1544 Mar  1 15:12 hc_ccptdb1.dat
-rw-r----- 1 oracle oinstall       39 Mar  1 17:12 initccptdb1.ora
-rw-r--r-- 1 oracle oinstall     2851 May 15  2009 init.ora
-rw-r----- 1 oracle oinstall     1536 Mar  9 10:05 orapwccptdb1
-rw-r----- 1 oracle asmadmin 21544960 May  6 17:37 snapcf_ccptdb1.f
wmrac01$scp orapwccptdb1 10.118.253.47://u01/product/oracle/11.2.0/db_1/dbs/orapwccptdb

四.在主庫與從庫中設定相應的環境變數
以oracle使用者登陸

六.對主庫做一次全備份
在主庫與從庫中建立相同的備份路徑
以oracle使用者登陸

$mkdir –p /data8/backup
$chmod 770 /data8/backup

做一次完整的RMAN熱備份


$rman target/
Rman> backup database format='/data/backup/%U_%s.bak';
Rman>sql"alter system archive log current";
Rman>backup filesperset 10 archivelog all format='/data/backup/%U_%s.bak';

alter database create standby controlfile as '/data/backup/dgcon01.ctl';


七.配置網路連線

九.啟動備庫
$sqlplus ‘/as sysdba’
Sql>startup nomount pfile=’/home/oracle/pfile.ora’;
Sql>alter database mount standby database;

採用LGWR程式傳輸日誌﹐必須建立備用日誌﹐而且日誌大小與主庫一樣﹐個數比主庫多一個
首先建立備用日誌

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 111 ('/data/ccptdb/dgredo111a.log','/data/ccptdb/dgredo111b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 112 ('/data/ccptdb/dgredo112a.log','/data/ccptdb/dgredo112b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 113 ('/data/ccptdb/dgredo113a.log','/data/ccptdb/dgredo113b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 114 ('/data/ccptdb/dgredo114a.log','/data/ccptdb/dgredo114b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 115 ('/data/ccptdb/dgredo115a.log','/data/ccptdb/dgredo115b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 116 ('/data/ccptdb/dgredo116a.log','/data/ccptdb/dgredo116b.log') SIZE 50M;

 

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 221 ('/data/ccptdb/dgredo221a.log','/data/ccptdb/dgredo221b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 222 ('/data/ccptdb/dgredo222a.log','/data/ccptdb/dgredo222b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 223 ('/data/ccptdb/dgredo223a.log','/data/ccptdb/dgredo223b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 224 ('/data/ccptdb/dgredo224a.log','/data/ccptdb/dgredo224b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 225 ('/data/ccptdb/dgredo225a.log','/data/ccptdb/dgredo225b.log') SIZE 50M;

SQL>ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 226 ('/data/ccptdb/dgredo226a.log','/data/ccptdb/dgredo226b.log') SIZE 50M;


使用RMAN進行恢復
$rman target/
Rman>restore database;
Rman>restore archvielog all;
然後直接進入管理恢復狀態
$sqlplus ‘/as sysdba’
Sql>alter database recover managed standby database disconnect from session;

十.由於主庫為ASM檔案系統﹐需要將ASM格式的資料檔案轉化為普通檔案格式(如果有別名﹐則自動轉換﹐此步是可選項)

alter system set standby_file_management=manual ;

alter database rename file '/data/ccptdb/system.260.744649997' to '/data/ccptdb/system01.dbf' ;
alter database rename file '/data/ccptdb/sysaux.261.744650015' to '/data/ccptdb/sysaux01.dbf' ;
alter database rename file '/data/ccptdb/undotbs1.262.744650027' to '/data/ccptdb/undotbs101.dbf' ;
alter database rename file '/data/ccptdb/undotbs2.264.744650051' to '/data/ccptdb/undotbs201.dbf' ;
alter database rename file '/data/ccptdb/users.265.744650057' to '/data/ccptdb/users01.dbf' ;

為了standby啟用後可正常使用需要新增tempfile

alter tablespace temp add tempfile '/data/ccptdb/temp01.dbf' size 2000m;
alter tablespace temp add tempfile '/data/ccptdb/temp02.dbf' size 2000m;

由於ASM格式的資料檔案存在﹐在standby開啟後用TOAD無法正常顯示錶空間﹐需要刪除以下ASM格式的資料檔案

alter database tempfile '+DATA/ccptdb/tempfile/temp.263.744650033' offline;
alter database tempfile '+DATA/ccptdb/tempfile/temp.263.744650033' drop;

alter system set standby_file_management=auto ;


十一.關閉standby﹐重啟並高置為實時運用模式
shutdown immediate
startup
alter database recover managed standby database using current logfile;
