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.

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
