Hello Frank,

According to this article: https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/create-enterprise-geodatabas... 

You must have ArcGIS Desktop (Standard or Advanced), ArcGIS Pro (Standard or Advanced), ArcGIS Engine with the Geodatabase Update extension, or ArcGIS Server installed on the computer where you'll create the geodatabase. If you're using Oracle or SQL Server, you must also install and configure a database management system client on the computer where the ArcGIS client is installed.
