Oracle database requirements for ArcGIS 10.5.x—System Requirements | ArcGIS Desktop
*You must install ArcGIS 10.5.1 (Desktop, Engine, Server) Oracle critical issues and 12.2.01 Support Patch on all 10.5.1 client machines to use Oracle 12.2.01 with ArcGIS
I think connection from ArcGIS Desktop 10.5 is not supported. You will need Desktop 10.5.1 along with the below patch:
ArcGIS 10.5.1 (Desktop, Engine, Server) Oracle critical issues and 18.104.22.168 support Patch
Also, make sure you are putting the correct hostname in the connection file.
any idea abt this ???
You must have ArcGIS 10.5 installed.....the patch is for ArcGIS 10.5.1. Desktop 10.5 and Desktop 10.5.1 are different ArcGIS Desktop versions.
So download the setup for ArcGIS Desktop 10.5.1, install it, install the patch and then try connecting to your Database.
