Oracle DataGuard 简单配置

Oracle DataGuard 简单配置

Oracle DataGuard  太恶心了，弄了这么长时间～下面我来介绍一下最简单的安装方法～

1，首先装两个相同目录的oracle（可以选择不同的目录），因为我用的是虚机，所以默认装在c:\app下

2，在primary库上配置client参数，tnsnames.ora 和 listener.ora， standby上面也是同理～

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = C:\app\product\11.2.0\dbhome_1)
    )

  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.70.254)(PORT = 1521))
    )
  )

ORCL254 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.70.254)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
 
ORCL253 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.70.253)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

3, enable logging:

进入sqlplus，执行alter database force logging;

4,查看日志是否归档

archive log list;

如果没有的话就执行，

SQL> STARTUP MOUNT;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE OPEN;

5，重新定义pfile文件

create pfile='c:\pfile.ora' from spfile

修改对应的pfile文件（其他文档说还要备份，不用累他们～），在后面加上下面这些内容

DB_UNIQUE_NAME=orcl254
LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl254,orcl253)'
LOG_ARCHIVE_DEST_1='LOCATION=c:\app\oradata\orcl\ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcl254'
LOG_ARCHIVE_DEST_2='SERVICE=orcl253 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl253'
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
FAL_SERVER=orcl
FAL_CLIENT=orcl
DB_FILE_NAME_CONVERT='oradata\orcl253','oradata\orcl254'
LOG_FILE_NAME_CONVERT='oradata\orcl253','oradata\orcl254'
STANDBY_FILE_MANAGEMENT=AUTO

执行：

create spfile from pfile='c:\pfile.ora'
