Step2:配置Oracle Dataguard

接着step1我用Rman duplicate测试下.

1,2两步请参考step1中的1，2

3.startup nomount (standby),一定要是nomount.

4.rman duplicate(primary)

4.restart standby database.

5.check dg ok

6.但是发现duplicate 有报错信息,这个是因为备库没有配置log_file_name_convert的原因,同样redolog也没有生成.

7.下面我配置一下这个参数

RMAN>

可以看到上面没有报错,而且redolog也产生啦

[root@dg2 oradata]# ls
con.ctl  sysaux.dbf  system.dbf  undotbs1.dbf
[root@dg2 oradata]# ls
con.ctl  sysaux.dbf  system.dbf  undotbs1.dbf
[root@dg2 oradata]# ls
con.ctl  redo1.log  redo2.log  redo3.log  sysaux.dbf  system.dbf  undotbs1.dbf
[root@dg2 oradata]# ls
con.ctl  redo1.log  redo2.log  redo3.log  sysaux.dbf  system.dbf  undotbs1.dbf

8.看来还是duplicate简单的很多.接下来我会继续测试先做rman备份然后在去配置init parameter
