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;

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 /

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        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    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.

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>   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>
DOC>   1. Query showing jobs created by UTL_RECOMP
