Problems with database connection #108

Closed uvchik closed 4 years ago

uvchik commented 4 years ago

I improved the error message to understand the reason. Now we get the following error message:

ConnectionError: Database (oep) connection not successful. 
URL: http://oep.iks.cs.ovgu.de//api/v0/schema/supply/tables/wind_turbine_library/rows/?
Response: [400] 
{"reason": "Connection limit for anonymous users is exceeded. Please login to get your own connection pool."}

How shall we deal with it?

Seems like the limit of anon connections to the OEP is exceeded. Busy day ;)

One simple solution is to include the user/token input in the code. The need to create a good template and improve the documentation for this is obvious.

You can find the API-Tutorials here: https://openenergy-platform.org/tutorials/

Here is the party with the token: https://openenergy-platform.org/tutorials/61201725-493f-4dd0-b9aa-6e0f6d6aa550/

I have received the same message today for trying to get weather data from open_FRED, does this mean that I need to follow the above tutorials and sign up/get a token? Or will it work if I try another day when the limit for connections hasn't been exceeded? Thanks

By now the bug is resolved but it can occur again. We should talk about the OEP connection in general.

It might have been a single event, so we may keep everything as it is until it happens again.
