Step by Step guide to Install Oracle 11g on Ubuntu VM

After downloading the Ubuntu VMWare image, there were few more quirks to settle.
I had to install NFS and SSH on the machine to make it accessible by ssh from Windows.

Following are the commands:
sudo apt-get install openssh-server openssh-client

sudo apt-get install nfs-kernel-server nfs-common portmap

Now I setup the samba share on this machine

sudo aptitude install samba

https://help.ubuntu.com/community/SettingUpSamba

After installing the samba, create a directory on the FS which you want to share with Windows or other systems.
Then edit /etc/samba/smb.conf and add these lines to the end

[share_name]
        comment = Share to Linux
        path = /home/user/winshare
        guest ok = yes
        writeable = yes

You can use the following commands to restart the services if needed:
/etc/init.d/nfs-common restart
/etc/init.d/samba restart

Process to install the Oracle on Ubuntu starts

This page is particularly helpful and is worth reading every bit:
http://www.pythian.com/blogs/654/installing-oracle-11g-on-ubuntu-linux-710-gutsy-gibbon

It mentions the packages that need to be updated before Oracle Installation.

apt-get update
apt-get upgrade (This would update the packages from the internet and will take sometime)

Anyways follow step by step the instructions in the above link to complete the installation.

At some point of time, you will encounter insufficient disk space in Linux due to which you cannot install Oracle.
To add more disk space to the Linux VM, follow the link below

I allocated a 20GB SCSI HD to Linux VM and split it into 3 partitions. The FSTAB entries are:
/dev/sdb1 /u01 ext3 defaults 1 1
/dev/sdb2 /oradata ext3 defaults 1 1
/dev/sdb3 /data ext3 defaults 1 1

Also, the Oracle installer needs a GUI. So, you need an X-Server (like eXceed) to complete the installation.
Simply on command prompt, set DISPLAY

For bash- > export DISPLAY=ExceedHostIP:0.0

And then start Exceed on Windows and connect to the IP address of the VM linux. Try 3-4 times to connect as it may error out.

If you get a timeout error, ignore the message and press nothing. Continue with Installation and complete the post-installation steps in
