Oracle ASM实例同filesystem间的文件传输

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;

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

3:使用rman的convert命令来实现，同样适用于10g
