Oracle工具之--ASM与文件系统及跨网络传输文件 Oracle DBMS_FILE_TRANSFER可以实现文件系统和ASM磁盘组之间实现文件传输及ASM磁盘组之间跨网络的传输。
DBMS_FILE_TRANSFER：
The DBMS_FILE_TRANSFER package provides procedures to copy a binary file within a database or to transfer a binary file between databases.
[oracle@node1 ~]$sqlplus / as sysdba
SQL> desc dbms_file_transfer
文件系统与ASM磁盘组之间文件传送：
1、查看datafile存储信息
建立Oracle directory（ASM存储）
SQL> create directory asm_dir as '+DG1/prod/datafile';
Directory created.
建立Oracle directory（文件系统）
[root@node2 ~]# mkdir /u01/bak
[root@node2 ~]# chown oracle:dba /u01/bak
SQL> create directory fs_dir as '/u01/bak';
Directory created.
3、表空间做热备
16:04:26 SYS@ prod1>alter tablespace users begin backup;
Tablespace altered.
备份ASM磁盘组文件到文件系统：
SQL> exec dbms_file_transfer.copy_file('ASM_DIR','users.259.852292709','FS_DIR','users01.dbf');
PL/SQL procedure successfully completed.
参数信息：
1、源文件目录
2、源文件名
3、目标文件目录
4、目标文件
16:04:36 SYS@ prod1>alter tablespace users end backup;
Tablespace altered.
4、验证文件传送情况
[oracle@node2 ~]$ ls -lh /u01/bak
total 5.1M
-rw-r----- 1 oracle asmadmin 5.1M Jul 7 17:18 users01.dbf
文件传送成功！
5、从文件系统传送文件到ASM磁盘组
16:07:51 SYS@ prod2>exec dbms_file_transfer.copy_file('FS_DIR','users01.dbf' ,'ASM_DIR','TEST01.DBF');
PL/SQL procedure successfully completed.
Elapsed: 00:00:02.25
6、验证文件传送
ASMCMD>cd +dg1/prod/datafile
ASMCMD> ls
