Whilst BICS comes with complete Schema as a Service, some customers choose to use database as a service (DBaaS) for many reasons (such as the ability to use the on-premise modelling tool and “lift and shift” the model). DBaaS has recently been upgraded to offer 12.2 as an option for the database which is what we were trialling as part of internal R&D whilst we were formulating some recommendations for a BICS customer.
Whilst doing this we encountered a couple of issues with connectivity but fortunately we were helped out by this paper that has just been released by Oracle in February 2017 called “Known Issues for Oracle Business Intelligence Cloud Service”.

In addition this paper covers a few other things you will likely want to know about, so if you have embarked on a BICS installation then I highly recommend giving this a quick read.
