oracle FTP服务——Using FTP with Oracle ASM Files

若数据库用ASM文件系统进行管理，那么在文件下载、上传方面有些困难，即使使用了asmcmd工具，也没有类似cp的命令来复制其中的文件，于是oracle提供了ftp来实现一系列ASM文件的管理。

Using FTP with Oracle ASM Files

http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb22pro.htm#ADXDB5537

Oracle Automatic Storage Management (Oracle ASM) organizes database files into disk groups for simplified management and added benefits such as database mirroring and I/O balancing.Database administrators can use protocols and resource APIs to access Oracle ASM files in the Oracle XML DB repositoryvirtual folder/sys/asm. All files in/sys/asm are binary.

Typical uses are listing, copying, moving, creating, and deleting Oracle ASM files and folders.Example 28-1 is an example of navigating the Oracle ASM virtual folder and listing the files in a subfolder.

The structure of the Oracle ASM virtual folder, /sys/asm, is described inChapter 21, "Accessing Oracle XML DB Repository Data". InExample 28-1, the disk groups are DATA and RECOVERY; the database name isMFG; and the directories created for aliases aredbs andtmp. This example navigates to a subfolder, lists its files, and copies a file to the local file system.

要使用ftp必须先再监听内配置端口：

如：SQL> @$ORACLE_HOME/rdbms/admin/catxdbdbca.sql 7777 8888

用sys用户执行以上语句，后面的两个端口可以自己指定，7070是ftp端口，8080是web端口。

查看下监听:

oel57t1:oracle:rac2 > lsnrctl status

出现以下内容，表示配置成功：

Listening Endpoints Summary...
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.241)(PORT=1521)))
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.51)(PORT=1521)))
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=OEL57t1)(PORT=7777))(Presentation=FTP)(Session=RAW))
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=OEL57t1)(PORT=8888))(Presentation=HTTP)(Session=RAW))

Example 28-1 Navigating Oracle ASM Folders

ftp> open myhost 7777 ftp> user system
Password required for SYSTEM
Password: password
ftp> cd /sys/asm ftp> ls
DATA
RECOVERY
ftp> cd DATA ftp> ls
dbs
MFG
ftp> cd dbs ftp> ls
t_dbl.f
t_axl.f
ftp> binary ftp> get t_dbl.f, t_axl.f ftp> put my_db2.f

In Example 28-1, after connecting to and logging onto database myhost (first four lines), FTP methodscdand ls are used to navigate and list folders, respectively. When in folder/sys/asm/DATA/dbs, FTP commandgetis used to copy filest_db1.f and t_ax1.f to the current folder of the local file system. Then, FTP commandputis used to copy filemy_db2.f from the local file system to folder/sys/asm/DATA/dbs.

最常用的命令有：

ls 列出远程机的当前目录
cd 在远程机上改变工作目录
lcd 在本地机上改变工作目录
ascii 设置文件传输方式为ASCII模式
binary 设置文件传输方式为二进制模式
close 终止当前的ftp会话
hash 每次传输完数据缓冲区中的数据后就显示一个#号
get（mget） 从远程机传送指定文件到本地机
put（mput） 从本地机传送指定文件到远程机
open 连接远程ftp站点
bye 断开与远程机的连接并退出ftp
