Our IT department is considering upgrading our Oracle database servers to version 188.8.131.52.0. Does Bentley Facilities Space planner V8i fully support this version?
No, the last commercial release of Facilities Space Planner V8i predates Oracle 12 so it is not supported. Also, since Bentley Facilities Space Planner runs on ProjectWise it is also completely reliant on its base requirements as well, and the newest version of Oracle supported by ProjectWise V8i is Oracle 11g (184.108.40.206); only ProjectWise CONNECT Edition supports Oracle v12.x.
