Those are the "real" process names.

You have renamed your executable so ps show you the correct name.

However you are using a 2.6.8 kernel and you don't need a wrapper (and renaming the oracle executable).
Simply set hugetlb_shm_group (look around in google) with your oracle GID and insert vm/hugetlb_shm_group in sysctl.conf accordly.
