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
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

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.
