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

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

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
