Oracle XE 11g R2 doesn't start

I am running Ubuntu 13.04. I am attempting to install Oracle XE 11g R2. It seems that everything was fine until I got to configuration of the database as root I ran /etc/init.d/oracle-xe configure command. I have received the following output


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 look at the logs I get the following error ORA-01034: ORACLE not available.  After receiving this error I have attempted to start Oracle manually.

ORA-00845: MEMORY_TARGET not supported on this system



As you can see I got ORA-00845: MEMORY_TARGET not supported on this system error. Ok let's see what's going on with my partitions


/u01/app/oracle/product/11.2.0/xe/config/log# 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/blah/.Private  633G  238G  363G  40% /home/blah

For some reason I have two tmpfs filesystems one is 6Gbs and another just under 800 Mbs. I figured if I add the following line to my fstab file I'll be fine

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