I have installed ArcGIS desktop 10.3.1 and can no longer make direct connections to ArcSDE 10.1 installed on Oracle 18.104.22.168.0. I can still make direct connections from Desktop 10.2.2. I get an error "This release is either invalid or out of date. Table not found SDE.GDB_Release. This is a table that does not exist in the Oracle geodatabase tables according to to the ESRI documentation and what is in my SDE schema. What's up?
I am able to make an application server connections to the database. I am using the 11.2.0 client.
