To use Oracle views, you need to do a couple of things.

Make sure that you have an entry in user_sdo_geom_metadata for the geometry column.

Add a pkey:
alter view <viewname> add constraint <constraintname> primary key (<columnlist>) disable novalidate;

Yes it is FDO_IDENTITY, you can  use comma to separate fields if needed

Caching and using of FD schema in applications is something we could talk a lot about in MG, Map and FDO :).
I have changed 3 times in provider in diff. versions if it cache FDO schema or not.

thanks for the information. I have deployed the SL King FDO metadata table
along with the SL Kinf FDO provider for Oracle on MGE 2010 (it works fine).
Which column of the SL Kinf FDO metadata table is actually defining in an
Oracle View the primary key? I would like to set my 'FID' as a primary key
in the FDO class.

Is it maybe the FDO_IDENTITY?!

With the Autodesk Oracle provider upon Oracle Views I have many issues that
concern probably the PK identifier (highlight colour does not show, new
added layers do not show up in MGE Studio, if not restarting the WWW and MG
service, ...). I think there is a lot of caching behing MGE or the Autodesk
