The purpose of this note is to provide details on a potential issue which can surface from June 2019 onwards and affect the interoperability of database links between older and newer RDBMS versions. The following notes provide more details / what action should be taken :

Some Oracle Clinical releases are certified with affected RDBMS versions i.e

and database links can exist in such environments (i.e replication is set up). Also there maybe a custom setup in place which extracts data from say a source Oracle Clinical '' database using database links and the target database pulling the data is running on say rdbms In such cases the required patches should be applied.
