PMFJI here, but one crucial misunderstanding you may have -- z/Linux
does *not* run under z/OS.  z/Linux runs in its own virtual machine
under z/VM (or on a bare LPAR), z/OS runs in its own separate LPAR
(though you *can* run z/OS in a virtual machine under z/VM, you probably
wouldn't want to for performance reasons).

IOW, Oracle will run in a separate z/Linux under z/VM in the LPAR that
z/VM runs on (can be on an IFL).  You will still need communications
between the Oracle under z/Linux and your z/OS applications just as you
do today, but the communications can be internal to the CEC instead of
over an external network.
