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
