unzipping problem

Hi,
I have downloaded the oracle 9i software from oracle website.
The file is in the following format.
"lnx_920_disk1.cpio.gz"
I need to unzip this file for installing oracle9i in my system.
I tried with the following command to unzip the file
"$gunzip lnx_920_disk1.cpio.gz"
but i am getting the error "gunzip:lnx_920_disk1.cpio:Read only file system".
How to unzip the above file?
Your help in this regard is highly appreciated.
cheers

Look at the message, it says "read only file system".

You could do

gunzip <lnx_920_disk1.cpio.gz >/some/writeable/partition

or even

switch to where you want to extract it to and do

gunzip </path/to/lnx_920_disk1.cpio.gz | cpio -ivdu
