把路徑建好
    mkdir /oracle/app/arch
    mkdir -p /oracle/app/admin/RACDG/adump
    mkdir /oracle/app/admin/RACDG/bdump
    mkdir /oracle/app/admin/RACDG/cdump
    mkdir /oracle/app/admin/RACDG/udump
    mkdir /oracle/app/admin/RACDG/pfile
    mkdir -p /oracle/app/oradata/RACDG
    
    
    
    
    
把密碼文件ftp過去，並且改名，後面爲sid

mv orapwRACDB1 orapwRACDG


在主庫tnsnames添加
RACDG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 180.200.2.78)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RACDG)
    )
  )
 




在主庫建立備份腳本
在這個目錄下/oracle/script

run{
allocate channel c1 type disk;
allocate channel c2 type disk;
set limit channel c1 kbytes 1800000;
set limit channel c2 kbytes 1800000;
backup full
       tag 'dbfull'
       format '/oracle/rman/full%n_%s_%p_%T'
database include current controlfile for standby;
sql 'alter system archive log current';
release channel c1;
release channel c2;
}

nohup rman target / @bk.rcv log bk.log &


ftp到備機的/oracle/backup/rman
目錄不一樣


備庫listener.ora

修改下面，改成RACDG
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = RACDG)
      (ORACLE_HOME = /oracle/app/product/11g)
      (SERVICE_NAME = RACDG)
    )
  )
 
 
備庫tnsname

添加


RACDB1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RACDB)
      (INSTANCE_NAME = RACDB1)
    )
  )

RACDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = node2-vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RACDB)
    )
  )

RACDB2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = node2-vip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RACDB)
      (INSTANCE_NAME = RACDB2)
    )
  )
 
RACDG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 180.200.2.78)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RACDG)
    )
  )


添加完這個記得要在/etc/hosts也要添加
180.200.2.55 node1
180.200.2.60 node2

180.200.2.57 node1-vip
180.200.2.58 node2-vip

10.10.17.221 node1-priv
10.10.17.222 node2-priv
 

備份一下原spfile
然後create spfile from pfile='/home/oracle/new.ora';

startup nomount



創建恢復腳本
在這個目錄下
/oracle/backup/script



catalog start with '/oracle/backup/rman';
run
{
    allocate channel chan1 type disk;
    allocate channel chan2 type disk;
    allocate auxiliary channel aux1 type disk;
    allocate auxiliary channel aux2 type disk;
duplicate target database for standby nofilenamecheck;
}

運行之前記得先開監聽

nohup rman target   sys/121212@RACDB1 auxiliary / @recover.rcv log recover.log &



catalog start with '/oracle/backup/rman';

using target database control file instead of recovery catalog
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of catalog command at 02/09/2002 03:56:01
ORA-01507: database not mounted


報錯，看來有點問題
用軟連接

ln -s /oracle/backup/rman /oracle/rman

終於ok了




shutdown immediate;  
startup nomount;
alter database  mount standby database;
alter database recover managed standby database disconnect from session;




ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 7('/oracle/app/oradata/RACDG/slog7.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 8('/oracle/app/oradata/RACDG/slog8.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 9('/oracle/app/oradata/RACDG/slog9.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 1 group 10('/oracle/app/oradata/RACDG/slog10.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 11('/oracle/app/oradata/RACDG/slog11.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 12('/oracle/app/oradata/RACDG/slog12.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 13('/oracle/app/oradata/RACDG/slog13.ora') SIZE 50m;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 14('/oracle/app/oradata/RACDG/slog14.ora') SIZE 50m;

alter database recover managed standby database disconnect from session;

select sequence#,applied,ARCHIVAL_THREAD# from v$archived_log order by sequence#;

後來不知道爲毛不同步了
PING[ARC0]: Heartbeat failed to connect to standby 'RACDG'. Error is 12154.
主庫node2的alert一直報這個問題



漏了在2機的tnsname添加
RACDG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 180.200.2.78)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RACDG)
    )
  )
 
加上去之後等一下，自己就會傳歸檔過去，一切正常
