为了简化加强asm管理，OracleR2推出了一个新的命令行工具:asmcmd.
让我们简单来看一下这个工具的用法。
1.登录
需要首先设置ORACLE_SID为ASM实例:
[oracle@danaly ~]$ export ORACLE_SID=+ASM
[oracle@danaly ~]$ asmcmd
ASMCMD>
|
2.第一版asmcmd提供的功能
ASMCMD> help
asmcmd [-p] [command]
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.
commands:
--------
cd
du
find
help
ls
lsct
lsdg
mkalias
mkdir
pwd
rm
rmalias
|
3.同常用的Unix/Linux命令类似
cd，pwd，ls，find等命令，可以帮助用户来检索asm管理下的文件:
ASMCMD> pwd
+
ASMCMD> ls
ORADG/
ASMCMD> ls -l
State Type Rebal Unbal Name
MOUNTED EXTERN N N ORADG/
ASMCMD> cd ORADG
ASMCMD> ls
DANALY/
ASMCMD> cd DANALY
ASMCMD> ls -l
Type Redund Striped Time Sys Name
Y CONTROLFILE/
Y DATAFILE/
Y ONLINELOG/
Y PARAMETERFILE/
Y TEMPFILE/
N spfiledanaly.ora => +ORADG/DANALY/PARAMETERFILE/ \\
spfile.269.600019515
ASMCMD> ls -l DATAFILE/
Type Redund Striped Time Sys Name
