ArcSDE should support zlinux (SLES or RHEL for System z, IBM Mainframe)

Does anyone have any idea about when or why not ArcSDE would be certified on zlinux (SLES or RHEL).
Now, ArcSDE is only supported linux on:
Linux x86, on CPUs that adhere to the x86 architecture (32-bit), with supported Linux releases
Linux x86_64, on CPUs that adhere to the x86_64 architecture (64-bit), with supported Linux releases

Now, my real question is:
Can I use
Oracle db server(zlinux, SLES11SP2 for mainframe, Oracle 11gr2) + Arcgis server(windows) + APP server(windows or linux, weblogic) to deliver a three-layers application architecture for an GIS system.

Someone told me it's impossible because the ArcSDE is not certified on zlinux, there are 3 lib file should be put into the Oracle db lib link:
libst_shapelib.so
libpe.so
libsg.so

Is this true?

ArcGIS does not support zLinux.  You can generally use Oracle on unsupported
platforms, but only as a two-tier architecure (Direct Connect), or with an application
server on a supported platform (but doing so isn't supported).  ST_GEOMETRY
SQL support would require a listener on a supported architecture (also unsupported).

Esri platform support decisions are made by senior management, not by the users
or participants in these forums.  You can create a new idea at the web site created
for Esri software suggestions, but I doubt that zLinux has the market share which
is generally required before a new platform is added.
