RMAN中建立Catalog 用数据库的例子

RMAN中可以备份metadata到control文件，也可以备份metadata到数据库中，此数据库称为catalog database。

本文参考网上文章，建立一个例子：

使用机器：

机器1：target 机  o_target.loc  192.168.10.111  要备份的数据库。

机器2：catalog 机 o_catalog.loc 192.168.10.112 RMAN catalog metadata 所保存的位置。

由于涉及到两台机器。

分别进行说说明：

在机器1上的/etc/hosts文件：

-----------------------------------------------------

[root@o_target ~]# cat /etc/hosts    
# Do not remove the following line, or various programs    
# that require network functionality will fail.    
127.0.0.1               localhost.localdomain localhost    
::1             localhost6.localdomain6 localhost6    
192.168.10.111  o_target.loc o_target    
192.168.10.112  o_catalog.loc o_catalog    
[root@o_target ~]#     
-----------------------------------------------------

在机器2上的/etc/hosts文件：

-----------------------------------------------------

[root@o_catalog ~]# cat /etc/hosts    
# Do not remove the following line, or various programs    
# that require network functionality will fail.    
127.0.0.1               localhost.localdomain localhost    
::1             localhost6.localdomain6 localhost6    
192.168.10.111  o_target.loc o_target    
192.168.10.112  o_catalog.loc o_catalog    
[root@o_catalog ~]#

-----------------------------------------------------

启动target机的数据库和lisenter:

-----------------------------------------------------

[root@o_target ~]# su - oracle    
[oracle@o_target ~]$ sqlplus / as sysdba

然后，在catalog机上，建立连接到target机的本地服务名：

-----------------------------------------------------

[root@o_catalog ~]# xhost +

[root@o_catalog ~]# su - oracle

Catalog机上，为rman 用户进行准备：

-----------------------------------------------------

[root@o_catalog ~]# su - oracle

在target机器上、为了从catalog机器上可以访问到target机器，进行设置：

------------------------------------------------------

[oracle@o_target ~]$ sqlplus / as sysdba
