Hi, After aplying the patch, I tried to connect with ArcGIS 10.5.1 Desktop to Oracle 12.2 64bits (Enterprise Linux - Oracle Developer days virtual machine). The ArcGIS 10.5.1 Desktop create the database connection but when I select it to connect, the ArcGIS Desktop blocks and stays Not Responding. I used several oracle client (and instant) both x64 and x32 (12.2 and 11.2.0.4 as it says on patch) I can connect through sqldeveloper and sql plus easy connect. Thanks, Gonçalo Revez
