MicroStation v8i oracle client 12

Does MicroStation V8i supports an oracle 12 client.

Bentley Map Select Series 4 supports the oracle 12 client.

Bentley Map SS4 requires MicroStation 08.11.09.714

So MicroStation 08.11.09.714 is, i think, the right version.

But there is no separate download of this MIcroStation-version.

Of course the alternative is an oracle-11-client

Questions,

Indeed do I really need this version?

Why can't I download this version?
