SolutionWhat seems to have been posted ar minimums from Oracle's metalink database. Oracle seems to assume nothing else runs on the box but their stuff.
I'm attaching a working kernel configuration kmtune output from a box that Runs 9.2.0.4 and ias 10G

Re: Kernel Changes
I agree with Steven, you need for SHMSEG at least 150 (thats for 1-2 small instances) more reasonable is to set it at >200...
e.g.
semmni 4306
semmns 8612
semmnu 4112
semume 30
shmmax 1073741824
shmmni 512
shmseg 200
st_large_recs 1
swchunk 4096
sysv_hash_locks 200
vps_ceiling 64
All the best
Victor
