随着Oracle 版本的升级，RMAN 也得到增强，在Oracle11g中的RMAN 支持不同操作系统和不同DB 之前的使用，关于RMAN 的兼容性，参考：
Oracle RMAN 兼容性 及 不同版本和不同平台之间使用 常见问题说明
这篇文章演示一个linux 下10g 恢复到11g中的示例。
Target 端：
DB： 11.2.0.3
Source 端：
OS：Oracle Linux 6.1 64位
DB： 10.2.0.5
1. 将10g 数据库 还原11g上
2. 升级还原的10g数据库到11g。
具体操作步骤如下。
在Source 备份之前，需要执行一下utlu112i.sql 脚本，如果不执行，那么在升级时执行 @?/rdbms/admin/catupgrd.sql 脚本时会报如下错误：

Miscellaneous Warnings
**********************************************************************
WARNING: --> Database is using atimezone file older than version 14.
.... After the release migration, it isrecommended that DBMS_DST package
.... be used to upgrade the 10.2.0.5.0database timezone version
.... to the latest version which comes withthe new release.
WARNING: --> EM Database ControlRepository exists in the database.
.... Direct downgrade of EM DatabaseControl is not supported. Refer to the
.... Upgrade Guide for instructions to savethe EM data prior to upgrade.
WARNING: --> Your recycle bin is turnedon and currently contains no objects.
.... Because it is REQUIRED that therecycle bin be empty prior to upgrading
.... and your recycle bin is turned on, youmay need to execute the command:
.... prior to executing your upgrade toconfirm the recycle bin is empty.

**********************************************************************
Recommendations
**********************************************************************
Oracle recommends gathering dictionarystatistics prior to
upgrading the database.
To gather dictionary statistics execute thefollowing command
execute dbms_stats.gather_dictionary_stats;
**********************************************************************
Oracle recommends reviewing any definedevents prior to upgrading.
To view existing non-default events executethe following commands
while connected AS SYSDBA:
Events:
SELECT (translate(value,chr(13)||chr(10),' ')) FROM sys.v$parameter2
WHERE UPPER(name) ='EVENT'AND isdefault='FALSE'
Trace Events:
SELECT (translate(value,chr(13)||chr(10),' ')) from sys.v$parameter2
WHERE UPPER(name) = '_TRACE_EVENTS' AND isdefault='FALSE'
Changes will need to be made in theinit.ora or spfile.
