utilities-p571(ASMCMD)--每日一译【2013-1-26】

Alias
An alias is a filename that is a reference (or pointer) to a system-generated filename,
but with a more user-friendly name. It is similar to a symbolic link in Unix operating
systems. You create aliases to make it easier to work with ASM filenames. You can
create an alias with an ALTER DISKGROUP command or with the mkalias ASMCMD

command.

别名

别名是一个与系统创建文件相关的或者是指向它的一个指针，这样它可以显得为一个更友好

的名字。它=同于在UNIX系统中的标识链接符。你可以创建别名在使用ASM文件名时将更简洁。

你可以建立一个别名使用“ALTER DISKGROUP”命令或者使用MKALIAS的ASMCMD命令。

An alias has at a minimum the disk group name as part of its complete path. You can
create aliases at the disk group level or in any system-generated or user-created
subdirectory. The following are examples of aliases:
+dgroup1/ctl1.f
+dgroup1/sample/ctl1.f
+dgroup1/mydir/ctl1.f
If you run the ASMCMD ls (list directory) with the -l flag, each alias is listed with
the system-generated file that it references.
ctl1.f => +dgroup2/sample/controlfile/Current.256.541956473

See Oracle Database Administrator's Guide for more information on aliases

一个别名它拥有一个最短的磁盘组的名字来替代它的全部路径。你可以创建别名在磁盘

组的级别或者在系统创建或者用户创建的子目录。以上为别名的例子：

如果你运行ASMCMD的LS（例出目录）使用-L标识，将会列出每个别名相关的系统创建的文件全称。
