I need to create couple of File Systems to install Oracle software and for other stuff that come along with it.
I used fdisk to create a partition (/fdisk /dev/sda) , but it is creating a ext2 partition. How to create a ext3 partition??
Also I am not sure about the entries that are required to edit the "/etc/fstab" for the newly created filesystem.
Can someone guide me with a step-by-step process?
I really appreciate your help.

Fdisk is fine for creating the "partition"
you format it as ext3
[root@bill01 ~]# fdisk /dev/sda
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 4500.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Thank YOU very much for quick response. I will use "mkfs.ext3" as you suggested.
