This is what I have :

# Controls the maximum shared segment size, in bytes
kernel.shmmax = 68719476736

# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 4294967296

# Oracle Database 11g Express Edition Recommended Values
kernel.sem = 250 32000 100 128
fs.file-max = 6815744

Is this a new installation or has it worked before?

First guess is that you do not have the shared memory and semaphores configured 
- should be in /etc/sysctl.conf
