AWR Snapshot listing empty results Oracle Database 12c Release 2 (12.2.0.1)
I was checking some performance issues in some databases and one of the issues I found was that I couldn’t get the snapshot IDs to choose the interval between “Begin” and “End” snapshot to create my report.

However, I didn’t expect to be surprised with the below error at the very beginning: I thought:” Did I miss Oracle Linux 8 isn’t supported with Oracle 19c?”.

I have already configured many accounts to use Oracle Cloud. Especially, since December 2020 I started to face some problems on the step where you must provide a credit card to simulate a payment but in fact, it works like a personal identification. So I have used the same card that I used previously in some setups, two other new cards and even asked some friends in different countries using their own cards and some of them have experienced the same erros while others could create their account successfully.
