数据文件传输:
    dbms_file_transfer.put_file();
    scp,单机普通文件系统->ASM
    windows->linux
    1.创建共享目录授予读写权限

    1. 源端
    2. mkidr /opt/oracle/backup
    3. create   directory   mydir as '/opt/oracle/backup'; 
    4. grant   read ,write on directory mydir  to public;  
    5. 目标端
    6. mkidr /opt/oracle/backup
    7. create  directory liunxdir  as '/opt/oracle/backup';   
    8. grant  read ,write  on directory    liunxdir   to public;

    2.创建数据库链接

    1.  create   public database link orcllink connect  to  system identified by "Oracle123" using '192.168.5.112:1521/orcl';

    3.调运存储过程传输文件

    1. BEGIN
    2.   dbms_file_transfer.put_file(source_directory_object => 'mydir'
    3.                              ,source_file_name => '08up46d2_1_1'
    4.                              ,destination_directory_object => 'liunxdir'
    5.                              ,destination_file_name => '08up46d2_1_1'
    6.                              ,destination_database => 'orcllink');
    7. END;
    8. /
