ORACLE之搭建DG（ADG方式）

目录(?)[+]

1.准备工作

        首先得准备两个能够PING通，并且装了Oracle软件且已经建库的Linux虚拟机。操作系统不限，至少有一个虚拟机已经建好库，最好两个都建好相同SID的库，这样少很多创建目录的麻烦，这里库的SID都是orcl，Linux严格区分大小写，所以SID的大小写得注意。

        我这里有两个名为PD和ST的Linux虚拟机。

        PD:192.168.56.42（主库）

        ST:192.168.56.43（备库）

2.在主库做一些操作

    2.1强制force logging

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.


Total System Global Area 1653518336 bytes
Fixed Size          2253784 bytes
Variable Size        1006636072 bytes
Database Buffers      637534208 bytes
Redo Buffers            7094272 bytes
Database mounted.
SQL> alter database force logging;    --修改数据库为强制记日志，这是必须的操作，主库的每一步操作都得记录到日志中去。

Database altered.

    2.2开启主库的归档模式

SQL> alter database archivelog;       --修改数据库为归档模式，因为dg是通过传送归档日志到备库然后应用来保证主备库一致的。

Database altered.

    2.3创建standby redo log

SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 4 ('/u01/app/oracle/oradata/orcl/redo04.log') size 50M;
Database altered.

SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 5 ('/u01/app/oracle/oradata/orcl/redo05.log') size 50M;
Database altered.

SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 ('/u01/app/oracle/oradata/orcl/redo06.log') size 50M;
Database altered.

SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 7 ('/u01/app/oracle/oradata/orcl/redo07.log') size 50M;

Database altered.

SQL> select group#,type,member from v$logfile;


    GROUP# TYPE    MEMBER
---------- ------- --------------------------------------------------
         3 ONLINE  /u01/app/oracle/oradata/orcl/redo03.log
         2 ONLINE  /u01/app/oracle/oradata/orcl/redo02.log
         1 ONLINE  /u01/app/oracle/oradata/orcl/redo01.log
         4 STANDBY  /u01/app/oracle/oradata/orcl/redo04.log
         5 STANDBY  /u01/app/oracle/oradata/orcl/redo05.log
         6 STANDBY  /u01/app/oracle/oradata/orcl/redo06.log
         7 STANDBY  /u01/app/oracle/oradata/orcl/redo07.log

    2.4创建pfile

SQL> create pfile from spfile;--这里创建pfile是为了做一些主库参数的配置，并且还得拷贝到备库再次修改成备库的配置。

File created.

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

    2.5创建主库归档目录

[oracle@PD orcl]$ mkdir archivelog  --建立这个目录是为了存放主库的归档日志文件，并且这个目录会和其他数据文件等等一起拷贝到备库。
[oracle@PD orcl]$ cd archivelog/
[oracle@PD archivelog]$ ls
[oracle@PD archivelog]$ pwd
/u01/app/oracle/oradata/orcl/archivelog

    2.6在主备库同时创建静态监听listener和tnsname

建议用net manager建立

主库orcl_pd:192.168.56.42

    2.8用pfile启动主库，并创建spfile

SQL> shutdown immediate

Database dismounted.
ORACLE instance shut down.
SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initorcl.ora'

    2.9创建主备库的备份目录

主库

[oracle@PD orcl]$ mkdir /u01/app/oracle/oradata/orcl/backup

备库

[oracle@PD orcl]$ mkdir /u01/app/oracle/oradata/orcl/backup

    2.10将口令验证文件和pfile发送到备库

name="code" class="sql">[oracle@PD dbs]$ pwd
