Common Oracle ASM commands

Common Oracle ASM commands
In the Oracle RAC environment, run asmcmd with the grid account to enter the asm command mode, for example:

[Grid @ oradb-node1 ~] $ Asmcmd

ASMCMD>

 

ASMCMD> du // display all disk space occupied by the ASM file in the specified ASM directory

ASMCMD> ls-ls // list the content, attributes, and disk space in the ASM directory.

ASMCMD> pwd // view the current path

ASMCMD> cd ../DATA // switch directory

ASMCMD> lsct // list information of the current ASM Client

ASMCMD> lsdg // list all disk groups and their attributes

ASMCMD> lsof // List Data File Information

ASMCMD> lsdsk // list disk Information

ASMCMD> rm-f *. dbf // delete all files with the. dbf extension.

ASMCMD> rm-fr orcldemo // Delete the current orcldemo directory

 

The root path of the ASM disk is "+" instead of "/". The following is a demonstration operation:

ASMCMD> cd datadg/demo

ASMCMD> pwd

+ Datadg/demo // The current path is + datadg/gd

ASMCMD> cd + // switch to the root path of the ASM Disk

ASMCMD> pwd

+ // The current path is the root path +

 

You can also choose not to enter the ASM command mode, such:

[Grid @ oradb-node1 ~] $ Asmcmd ls-ls // you can run the following command to view the usage of the ASM Disk:
