一般来讲，在ASM实例和文件系统之间传输文件，可以采用dbms_transfer_file包和rman实现外，或者FTP方式，FTP方式需要XML DB支持，目前还没有学会，因而先记录下前面三种方式…
1:使用dbms_file_transfer在文件系统和asm实例间传输文件，同样适用于10g
- SQL> desc dbms_file_transfer;
- PROCEDURE COPY_FILE
- Argument Name Type In/Out Default?
- ------------------------------ ----------------------- ------ --------
- SOURCE_DIRECTORY_OBJECT VARCHAR2 IN
- SOURCE_FILE_NAME VARCHAR2 IN
- DESTINATION_DIRECTORY_OBJECT VARCHAR2 IN
- DESTINATION_FILE_NAME VARCHAR2 IN
- PROCEDURE GET_FILE
- Argument Name Type In/Out Default?
- ------------------------------ ----------------------- ------ --------
- SOURCE_DIRECTORY_OBJECT VARCHAR2 IN
- SOURCE_FILE_NAME VARCHAR2 IN
- SOURCE_DATABASE VARCHAR2 IN
- DESTINATION_DIRECTORY_OBJECT VARCHAR2 IN
- DESTINATION_FILE_NAME VARCHAR2 IN
- PROCEDURE PUT_FILE
- Argument Name Type In/Out Default?
- ------------------------------ ----------------------- ------ --------
- SOURCE_DIRECTORY_OBJECT VARCHAR2 IN
- SOURCE_FILE_NAME VARCHAR2 IN
- DESTINATION_DIRECTORY_OBJECT VARCHAR2 IN
- DESTINATION_FILE_NAME VARCHAR2 IN
- DESTINATION_DATABASE VARCHAR2 IN
- SQL> select file_name from dba_data_files;
- FILE_NAME

- 3 end;
- 4 /

2: 11g的asm实例可以直接使用cp命令来实现，从asm实例的cp帮助信息上看，已经可以直接从本地数据库直接cp到远端数据库了！
- ASMCMD> cp /u01/app/oracle/oradata/ogg1/transfer_test01.dbf +data/ogg1/datafile/test01.dbf
- copying /u01/app/oracle/oradata/ogg1/transfer_test01.dbf -> +data/ogg1/datafile/test01.dbf
- ASMCMD> pwd
- +data/ogg1/datafile
- ASMCMD> ls -l

- DATAFILE UNPROT COARSE MAR 01 20:00:00 Y USERS.259.773712985
- N test01.dbf => +DATA/ASM/DATAFILE/test01.dbf.268.776809913
- N transfer_test01.dbf =>
- +DATA/OGG1/DATAFILE/COPY_FILE.267.776809311
3:使用rman的convert命令来实现，同样适用于10g
- [oracle@oel1 ~]$ rman target /
- Recovery Manager: Release 11.2.0.3.0 - Production on Thu Mar 1 20:44:22 2012
- Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
- connected to target database: OGG1 (DBID=3952830770)
- RMAN> convert datafile '+data/ogg1/datafile/SYSTEM.256.773712985' format
- '/u01/app/oracle/oradata/ogg1/system01.dbf';
- Starting conversion at target at 2012-03-01-20:47:08
