I've noticed that when I find the data source for a layer in oracle sde it lists a temporary sde connection in the temp folder:
Instead of the actual sde connection that the layer is using.
Is this a normal part of python in ArcGIS Pro or is there a setting someplace that I'm missing?
What version of Pro are you using?
In Pro 2.1.2 I see Oracle SDE connections either in default Favorites location:
or in the project folder where the aprx is saved (that is project specific) but it's better to use the Favorite Location to share between aprxs.
