本篇文章给大家分享的是有关如何从ASM复制文件到文件系统，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
版本10.2.0.5
1、使用RMAN：
$ sqlplus "/as sysdba"
SQL*Plus: Release 10.2.0.5.0 - Production on Fri Mar 16 10:02:41 2012
Copyright (c) 1982, 2010, Oracle. All Rights Reserved.
Connected to an idle instance.
SQL> startup mount;
ORACLE instance started.

SQL> select file#, name, bytes from v$datafile where file#=5;
FILE# NAME BYTES---------- -------------------------------------------------- ---------- 5 +DATA01/dbname/datafile/users.264.730552875 524288000
$ rman target / nocatalog
Recovery Manager: Release 10.2.0.5.0 - Production on Fri Mar 16 10:06:08 2012

[@more@]
2、使用dbms_file_transfer包：
SQL> select open_mode from v$database;
OPEN_MODE----------READ WRITE
SQL> create or replace directory SOURCE_DIR1 as '+DATA01/dbname/onlinelog/';
Directory created.
SQL> create or replace directory ORACLE_DEST as '/arch2/';
Directory created.
SQL> SQL> BEGIN 2 dbms_file_transfer.copy_file(
3 source_directory_object =>'SOURCE_DIR1',
4 source_file_name => 'group_1.274.730565825',
5 destination_directory_object => 'ORACLE_DEST',
6 destination_file_name => 'group_1.274.730565825'
7 ); 8 END; 9 /
PL/SQL procedure successfully completed.
SQL> ! ls -l /arch2/group_1.274.730565825-rw-r----- 1 oracle oinstall 524288512 Mar 14 10:49 /arch2/group_1.274.730565825 |
