2、is) ,This can occur as part of an Oracle version upgrade (Oracle 8i . Oracle 11G) or within the same Oracle version: (Oracle 10.2 to Oracle 10.2). -可以将 Oracle DB 从一个操作系统迁移到另一个操作系统，比如从 windows 到 Solaris，注意这里的迁移仅仅是数据的迁移，不包含 DB 的安装介 质。这个迁移可以是不同 DB 版本的迁移，比如从 8i 到 11g，也可以是相同版 本的迁移，比如从 10.2 到 10.2.Changes
3、 within an Operating System (ie: Linux,Windows or Solaris from 32 bit to 64 bit) are not considered cross platform migrations and are performed as normal version upgrades/wordsize conversions. -改变操作系统不用考虑系统的平台，可以按照正常的 db version upgrades 和 wordsize 的改变来操作。1 解决方法There is no migration utility (Script
4、or DBUA) to perform a cross platform migration of an Oracle Database. -没有迁移工具如脚本或者 DBUA 来执行跨 OS 的数据迁移。Changing platforms requires the database be re-built and / or the data moved using one of the following methods: -跨平台的迁移需要重建数据库，然后使用如下的一种方法来完成数据的迁 移工作。 (1) Export / Import to include the use of Data

6、Standbys (7) Oracle Golden GateEach available choice will have strengths and limitations to include data types, time required and potential costs. -每一个可选的方法都有它的优势和限制，如数据类型，需要的时间和一些 潜在的消耗。The choices available will depend on BOTH the Operating System and Oracle versions on both the source and destina

8、用 DG 的异构平台来迁移时，就会有操作系统的限制。 关于这块 内容，之前有详细的 Blog： Oracle Data Guard 支持的异构平台 说明 http:/ Convert Database only works if both source and destination belong to the same ENDIAN format. -RMAN Convert DB 仅在 source 和 destination 的 ENDIAN 格式相同的情 况下才可以使用。 RMANs convert function for Transportable Tablespaces will
9、 convert from one ENDIAN format to another. 在 ENDIAN 格式不同的情况下，可以使用 RMAN convert function 来转换 ENDIAN 从一种格式到另一种格式。如：RMAN convert tablespace TBS1 to platform=“Linux IA (32-bit)“ FORMAT /tmp/%U;两端相同之后，就可以进行 Transportable tablespace 的操作。可以通过 v$transportable_platform 视图查看系统的 ENDIAN 格式： SQL column platform
