I did a practice to migrate the oracle database from windows to linux operation system. The following is the operational process step by step. I recorded it in my blog for the future reference.
从10g开始，RMAN新增了CONVERT的语法，使得数据库文件可以跨版本复制，从这个特性开始，操作系统以及平台不再是数据库物理文件的限制了。
Oracle支持的可转换的平台可以在V$TRANSPORTABLE_PLATFORM视图中查询：
SQL> SELECT * FROM V$TRANSPORTABLE_PLATFORM;
PLATFORM_ID PLATFORM_NAME ENDIAN_FORMAT
----------- ---------------------------------------- ---------------------------

1 Solaris[tm] OE (32-bit) Big
2 Solaris[tm] OE (64-bit) Big

6 AIX-Based Systems (64-bit) Big
3 HP-UX (64-bit) Big
5 HP Tru64 UNIX Little
4 HP-UX IA (64-bit) Big
11 Linux IA (64-bit) Little
15 HP Open VMS Little
8 Microsoft Windows IA (64-bit) Little
PLATFORM_ID PLATFORM_NAME ENDIAN_FORMAT

9 IBM zSeries Based Linux Big
13 Linux 64-bit for AMD Little
16 Apple Mac OS Big
12 Microsoft Windows 64-bit for AMD Little
17 Solaris Operating System (x86) Little
18 IBM Power Based Linux Big
17 rows selected.
Oracle支持将数据文件转换为上面这些平台上的数据文件格式。
下面是我做的实验：
source platform:
os: Windows
oracle version: 10.2.0.1.0
Target platform:
os:Linux
oracle version:10.2.0.1.0
Source database ( Windows platform), the following operations are done on Windows platform.
1, 最开始碰到的问题是要求进行CONVERT的数据库必须处于只读状态
c:>sqlplus / as sysdba
SQL>shutdown immediate
SQL> startup open read only
2, Using RMAN to convert database
C:>rman target /

Run SQL script D:TRANS_SRCIPT.SQL on the target platform to create database
Edit init.ora file D:TRANSINIT_00OJ5L2R_1_0.ORA. This PFILE will be used to create the database on the target platform
To recompile all PL/SQL modules, run utlirp.sql and utlrp.sql on the target platform
To change the internal database identifier, use DBNEWID Utility

SQL> Rem NAME
SQL> Rem utlrp.sql - Recompile invalid objects
SQL> Rem
SQL> Rem DESCRIPTION
SQL> Rem This script recompiles invalid objects in the database.
SQL> Rem
SQL> Rem When run as one of the last steps during upgrade or downgrade,
SQL> Rem this script will validate all remaining invalid objects. It will
SQL> Rem also run a component validation procedure for each component in
SQL> Rem the database. See the README notes for your current release and
SQL> Rem the Oracle Database Upgrade book for more information about
SQL> Rem using utlrp.sql
SQL> Rem
SQL> Rem Although invalid objects are automatically re-validated when used,
SQL> Rem it is useful to run this script after an upgrade or downgrade and
SQL> Rem after applying a patch. This minimizes latencies caused by
SQL> Rem on-demand recompilation. Oracle strongly recommends running this
SQL> Rem script after upgrades, downgrades and patches.
SQL> Rem
SQL> Rem NOTES
SQL> Rem * This script must be run using SQL*PLUS.
SQL> Rem * You must be connected AS SYSDBA to run this script.
SQL> Rem * There should be no other DDL on the database while running the
SQL> Rem script. Not following this recommendation may lead to deadlocks.

SQL> Rem NAME
SQL> Rem utlprp.sql - Recompile invalid objects in the database
SQL> Rem
SQL> Rem DESCRIPTION
SQL> Rem This script recompiles invalid objects in the database.
SQL> Rem
SQL> Rem This script is typically used to recompile invalid objects
SQL> Rem remaining at the end of a database upgrade or downgrade.
SQL> Rem
SQL> Rem Although invalid objects are automatically recompiled on demand,
SQL> Rem running this script ahead of time will reduce or eliminate
SQL> Rem latencies due to automatic recompilation.
SQL> Rem
SQL> Rem This script is a wrapper based on the UTL_RECOMP package.
SQL> Rem UTL_RECOMP provides a more general recompilation interface,
SQL> Rem including options to recompile objects in a single schema. Please
SQL> Rem see the documentation for package UTL_RECOMP for more details.
SQL> Rem
SQL> Rem INPUTS
SQL> Rem The degree of parallelism for recompilation can be controlled by
SQL> Rem providing a parameter to this script. If this parameter is 0 or
SQL> Rem NULL, UTL_RECOMP will automatically determine the appropriate
SQL> Rem level of parallelism based on Oracle parameters cpu_count and
SQL> Rem parallel_threads_per_cpu. If the parameter is 1, sequential
SQL> Rem recompilation is used. Please see the documentation for package
SQL> Rem UTL_RECOMP for more details.
SQL> Rem
SQL> Rem NOTES
SQL> Rem * You must be connected AS SYSDBA to run this script.
SQL> Rem * There should be no other DDL on the database while running the
SQL> Rem script. Not following this recommendation may lead to deadlocks.

SQL> DOC
DOC> The following PL/SQL block invokes UTL_RECOMP to recompile invalid
DOC> objects in the database. Recompilation time is proportional to the
DOC> number of invalid objects in the database, so this command may take
DOC> a long time to execute on a database with a large number of invalid
DOC> objects.
DOC>
DOC> Use the following queries to track recompilation progress:
DOC>
DOC> 1. Query returning the number of invalid objects remaining. This
DOC> number should decrease with time.
DOC> SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);
DOC>
DOC> 2. Query returning the number of objects compiled so far. This number
DOC> should increase with time.
DOC> SELECT COUNT(*) FROM UTL_RECOMP_COMPILED;
DOC>
DOC> This script automatically chooses serial or parallel recompilation
DOC> based on the number of CPUs available (parameter cpu_count) multiplied
DOC> by the number of threads per CPU (parameter parallel_threads_per_cpu).
DOC> On RAC, this number is added across all RAC nodes.
DOC>
DOC> UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel
DOC> recompilation. Jobs are created without instance affinity so that they
DOC> can migrate across RAC nodes. Use the following queries to verify
DOC> whether UTL_RECOMP jobs are being created and run correctly:
DOC>
DOC> 1. Query showing jobs created by UTL_RECOMP
DOC> SELECT job_name FROM dba_scheduler_jobs
DOC> WHERE job_name like 'UTL_RECOMP_SLAVE_%';
DOC>
DOC> 2. Query showing UTL_RECOMP jobs that are running
DOC> SELECT job_name FROM dba_scheduler_running_jobs
DOC> WHERE job_name like 'UTL_RECOMP_SLAVE_%';
