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)
建议用net manager建立

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

2.7修改主库pfile文件

2.8用pfile启动主库,并创建spfile
SQL> shutdown immediate ORA-01109: database not open Database dismounted. ORACLE instance shut down. SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initorcl.ora' ORACLE instance started.

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
<pre name="code" class="sql">[oracle@PD dbs]$ pwd /u01/app/oracle/product/11.2.0/dbhome_1/dbs [oracle@PD dbs]$ scp orapworcl 192.168.56.43:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/ oracle@192.168.56.43's password: orapworcl 100% 1536 1.5KB/s 00:00 [oracle@PD dbs]$ scp initorcl.ora 192.168.56.43:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/ oracle@192.168.56.43's password: initorcl.ora 100% 1408 1.4KB/s 00:00
