[原]配置RMAN恢复目录应注意兼容性

      近日打算对灾备的Oracle备份进行优化，其中一项就是引入恢复目录（Recover Catalog）进行管理，但是在测试过程中遇到了一个问题，记录如下：

      创建恢复目录所需要的表空间、相应的用户并赋予相应的权限：

create tablespace rman
datafile 
  '/u02/oradata/mydb/rman01.dbf' size 50M autoextend on
logging
segment space management auto
extent management local;

create user rman
identified by rman
default tablespace rman;
alter user rman quota unlimited on rman;

grant connect to rman;
grant resource to rman;
grant create any view to rman;
grant recovery_catalog_owner to rman;
revoke unlimited tablespace from rman;

      在注册target为Oracle 11g（11.2.0.2）的数据库时出现了错误。

[oracle@test01 admin]$ rman target / catalog rman/rman@catalog

      经查证是RMAN的各组件之间的兼容性所导致的问题，下表转自：http://download.oracle.com/docs/cd/E11882_01/backup.112/e10643/compat003.htm#i634479

      作为catalog的数据库版本是10.2.0.1，这就是问题所在。
