Installing Oracle XE 11G R2 on Ubuntu 13.04

I am installing Oracle XE 11G R2 on Ubuntu 13.04. When I attempt to configure database using start up service /etc/init.d/oracle-xe configure I get the following messages



Starting Oracle Net Listener...Done

Configuring database...

Database Configuration failed.  Look into /u01/app/oracle/product/11.2.0/xe/config/log for details


When I pick at the logs they all have  ORA-01034: ORACLE not available error. I have attempted to start database manually


sqlplus "/as sysdba"

Connected to an idle instance.


SQL> startup

ORA-00845: MEMORY_TARGET not supported on this system

After researching ORA-00845 error I figured all I need to do is to increase my tmpfs filesystem. I have edited my /etc/fstab file and added the following line


tmpfs /dev/shm tmpfs defaults,size=6g 0 0


Rebooted and ran df -h.



Filesystem               Size  Used Avail Use% Mounted on

/dev/sda1                 46G  9.7G   34G  23% /

none                     4.0K     0  4.0K   0% /sys/fs/cgroup

udev                     3.9G  4.0K  3.9G   1% /dev

tmpfs                    792M  964K  791M   1% /run

none                     5.0M     0  5.0M   0% /run/lock

tmpfs                    6.0G  164K  6.0G   1% /run/shm

none                     100M   24K  100M   1% /run/user

/dev/sda2                633G  238G  363G  40% /home

/home/username/.Private  633G  238G  363G  40% /home/username


Now I have two tmpfs filesystems a one is just under 800 MBs the other 6Gbs. Still when I try to start db manually I get ORA-00845 error.


Please help with the set up.


Thank you.
