跨平台传输数据库
RMAN的convert database命令被用来将整个数据库从一个平台移动到另一个平台。当源平台与目标平台字节序相同时，RMAN会在目标平台自动完成创建新数据库的大部分操作。当跨平台传输数据库时convertdatabase命令的处理过程将会很长。与传输表空间一样，RMAN的convert database命令可以在源平台或目标平台执行。
当跨平台传输数据库时文件会自动被传输到目标平台，这些文件包括：
1.属于永久表空间的数据文件,注意，不管源平台与目标平吧的字节序是否相同，传输数据库的数据文件必须要进行转换不能简单的从一个平台复制到另一个平台。与跨平台传输表空间不一样，传输整个数据库要求特定类型的数据块，比如undo段，要被重新格式化确保与目标平台兼容
2.如果使用PFILE，PFILE文件会被传输。如果使用SPFILE，会基于SPFILE生成PFILE并将其传输，并在目标平基于PFILE来生成新的SPFILE。注意，在大多数情况下，PFILE文件中的有些参数对于新数据库需要手动修改。例如db_name,control_files
跨平台传输数据库的限制
跨平台传输数据库的主要限制是源平台与目标平台必须有相同的字节序。例如，当将数据库从Windows平台传输到Linux平台（都是小字节序）或者从HP-UX到AIX(都是大字节序),不能将整个数据库从HP-UX传输到Linux平台上。然而，可以在目标平台上创建一个新数据库，并使用表空间传输功能将需要的表空间从源数据库中使用跨平台与跨字节序传输到目标数据库中。
在源平台执行转换
将32位windows平台上的数据库jingyong(10.2.0.1)迁移到32位的Linux平台上(10.2.0.5)。在源平台上执行RMAN的convert database操作的步骤如下:
1.将源数据库以只读模式打开
C:\Users\Administrator>sqlplus / as sysdba SQL*Plus: Release 10.2.0.1.0 - Production on 星期二 3月 31 15:08:36 2015 Copyright (c) 1982, 2005, Oracle. All rights reserved. 连接到: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options SQL> shutdown immediate 数据库已经关闭。 已经卸载数据库。 ORACLE 例程已经关闭。 SQL> startup mount ORACLE 例程已经启动。 Total System Global Area 419430400 bytes Fixed Size 1249320 bytes Variable Size 125833176 bytes Database Buffers 285212672 bytes Redo Buffers 7135232 bytes 数据库装载完毕。 SQL> alter database open read only; 数据库已更改。
2.对源数据库执行dbms_tdb.check_db检查
SQL> set serveroutput on
SQL> declare
2 db_ready boolean;
3 begin
4 db_ready :=dbms_tdb.check_db('Linux IA (32-bit)',dbms_tdb.skip_readonly);
5 end;
6 /
PL/SQL procedure successfully completed
3.对源数据库执行dbms_tdb.check_external来识别外部对象
SQL> set serveroutput on; SQL> declare 2 external boolean; 3 begin 4 external:=dbms_tdb.check_external; 5 end; 6 / The following external tables exist in the database: SH.SALES_TRANSACTIONS_EXT The following directories exist in the database: SYS.TEST_DUMP, SYS.SUBDIR, SYS.XMLDIR, SYS.MEDIA_DIR, SYS.LOG_FILE_DIR, SYS.DATA_FILE_DIR, SYS.WORK_DIR, SYS.ADMIN_DIR, SYS.DATA_PUMP_DIR The following BFILEs exist in the database: PM.PRINT_MEDIA PL/SQL procedure successfully completed
4.执行convert database命令，指定目标平台和输出文件名称。RMAN会生成需要移动到目标平台上的文件，包含以下文件:
--数据库完整的数据文件副本
--在目标平台使用的新的PFILE参数文件，包含来自源数据库PFILE或SPFILE中的设置。在目标平台使用之前需要进行相应修改
--传输脚本，包含在目标平台创建新数据库的SQL语句
RMAN> convert database new database 'jingyong'
2> transport script 'E:\oradata\transport\transport_db_script.sql'
3> to platform 'Linux IA (32-bit)'
4> db_file_name_convert('E:\oradata\JINGYONG\DATAFILE', 'E:\oradata\transport','
E:\oradata\JINGYONG', 'E:\oradata\transport');

6.在目标主机上创建数据库需要的目录，并修改PFILE参数文件中的相关参数，并修改传输脚本中指示数据文件的位置。
创建相关目录
[oracle@oracle11g dbs]$ mkdir -p /u01/app/oracle/admin/jingyong/adump [oracle@oracle11g dbs]$ mkdir -p /u01/app/oracle/admin/jingyong/bdump [oracle@oracle11g dbs]$ mkdir -p /u01/app/oracle/admin/jingyong/cdump [oracle@oracle11g dbs]$ mkdir -p /u01/app/oracle/admin/jingyong/udump [oracle@oracle11g dbs]$ chmod -R 777 /u01/app/oracle/admin/jingyong*
修改PFILE参数文件
