I want to connect ArcGIS 10.6 to an Oracle 12c Enterprise Edition. However, I found different informations on the Esri websites on how to do so.
- I followed this website (http://desktop.arcgis.com/de/arcmap/latest/manage-data/gdbs-in-oracle/connect-oracle.htm) and executed it step by step. All worked fine, as far as I can tell. However, I got an Error message telling me that:
Failed to connect to specified server. Do you want to continue? Cannot connect to database because the database client software failed to load. Be sure the database client software is installed and configured correctly.
- I found this ESRI website https://desktop.arcgis.com/de/arcmap/latest/get-started/introduction/whats-new-in-arcgis.htm where it states that "Oracle Instant client will not work.", directly contradicting the instructions on website 1.
So what is right, respectivley, how can I connect ArcGIS 10.6 to Oracle 12c?
