Hello Jasper,

when moving to Oracle 12.2 (With SLES 12) some month ago we also had terrible performance problems with several sessions, caused by FULL TABLE SCANs coming from the generated Oracle execution plans.

In our case setting parameter optimizer_features_enable='' in the db_resource did solve most of that problems.
