--?使用ASMCMD?工具管理ASM目錄及文件

--==============================

?

????在ASM實例中，所有的存儲于ASM磁盤組中的文件對于操作系統命令而言是不可訪問的，因此也無法使用常規的命令來操縱ASM磁盤中的文

件。所幸的是，我們有ASMCMD工具來代替操作系統命令來完成這部分工作。ASMCMD工具提供了類似于操作系統的常用命令，如ls?,?du?,find

,cd?,rm?,mkdir等等。借助這些工具可以更輕松的完成ASM實例的相關管理工作。

????有關ASM的相關參考：

?

1.ASMCMD文件所在的位置

????[root@oradb ~]# su?-?oracle

????[oracle@oradb ~]$ which asmcmd

????/u01/oracle/10g/bin/asmcmd

?

2.啟動ASMCMD

????[oracle@oradb ~]$ export ORACLE_SID=+ASM????--啟動前要設定ORACLE_SID環境變量

????[oracle@oradb ~]$ asmcmd

????ASMCMD>?help

???????????asmcmd [-p] [command]????????--該方式可以直接完成相應的功能而不需要進入到ASMCMD提示符下

?

???????????The environment variables ORACLE_HOME?and?ORACLE_SID determine the

???????????instance?to?which the program connects,?and?ASMCMD establishes a

???????????bequeath connection?to?it,?in?the same manner?as?a SQLPLUS?/?AS

???????????SYSDBA.??The?user?must be a member?of?the SYSDBA?group.

?

???????????Specifying the?-p?option?allows the?current?directory?to?be displayed

???????????in?the command prompt,?like?so:

?

???????????ASMCMD [+DATAFILE/ORCL/CONTROLFILE]?>

?

???????????[command] specifies one?of?the following commands,?along?with?its

???????????parameters.

?

???????????Type?"help [command]"?to?get?help?on?a specific ASMCMD command.

??????????????????????????????????????--在asmcmd命令提示符下，輸入help [命令]?，則顯示該命令幫助信息

???????????commands:

???????????--------

???????????cd

???????????du

???????????find

???????????help

???????????ls

???????????lsct

???????????lsdg

???????????mkalias

???????????mkdir

???????????pwd

???????????rm

???????????rmalias

?

3.具體用法?????

4.從上面的描述可以看出ASMCMD工具給我們提供了很多方便，這些操作命令基本上與Liunx，Unix命令相似，通過這些操作命令可以大大簡化對

????ASM實例的管理。
