Purpose

Oracle database 10gR2 provides two new options to access and manage Automatic Storage Management (ASM) files and related information via command line interface - asmcmd and ASM ftp. This article will talk about asmcmd and provide sample Linux shell script to demonstrate the asmcmd in action.

Scope

asmcmd can be used by Oracle database administrators to query and manage their ASM systems. Oracle Support Services engineers can use asmcmd to easily retrieve ASM related info for diagnosing and debugging purposes.

asmcmd can be used against ASM versions 10gR1 (10.1.0.n) and 10gR2 (10.2.0.n). In ASM version 10.2 asmcmd is provided by default ASM installation.

To use asmcmd in ASM version 10.1 environment we can just copy relevant files from 10.2 installation into the 10.1 environment as follows. 

Linux/UNIX:

Copy/ftp asmcmd and asmcmdcore from 10.2 install into 10.1 $ORACLE_HOME/bin , where $ORACLE_HOME is the oracle home where ASM is installed. These two files should be owned by the oracle user and the dba group, and have the following permissions:

asmcmd: 550

asmcmdcore: 440

Windows:

Copy/ftp asmcmd.bat and asmcmdcore from 10.2 install into %ORACLE_HOME%\bin, where %ORACLE_HOME% is the oracle home where ASM is installed.
