Oracle Database Express Edition (XE)

Hello all,

I'm trying to get Oracle 11.2.0.2.0 XE working on Ubuntu 13.04.
For some reason I keep getting the error: "ORA-00845: MEMORY_TARGET not supported on this system". I have checked several forums for an answer. All problems had something to do with a tmpfs that is too small.
I have tried mounting tmpfs of 8G without any luck. I tried both tmpfs and shmfs.

Here's my configuration atm:

Filesystem Size Used Avail Use% Mounted on
/dev/sda6 110G 6.4G 98G 7% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 7.8G 4.0K 7.8G 1% /dev
tmpfs 1.6G 904K 1.6G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 6.0G 36K 6.0G 1% /run/shm
none 100M 28K 100M 1% /run/user
/dev/sda1 180M 45M 126M 27% /boot
/dev/sdb1 688G 2.5G 651G 1% /home
/home/ydbondt/.Private 688G 2.5G 651G 1% /home/ydbondt
shmfs 6.0G 36K 6.0G 1% /run/shm

Kernel info:
Linux DELL-YOURI 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux


I also have found another error in clsc.log:

Oracle Database 11g Clusterware Release 11.2.0.2.0 - Production Copyright 1996, 2010 Oracle. All rights reserved.
[ CLSE][1032939328]clse_get_crs_home: Error retrieving OLR configuration [0] [Error opening olr.loc file. No such file or directory]

Any ideas ?
