In today’s video we take a look at the PDB Snapshot Carousel feature, introduced in Oracle 18c.
I also have a Multitenant YouTube playlist.
There’s a lot more information about this feature and other multitenant functionality in these articles.
The star of today’s video is Nassyam Basha. 🙂

My guess would be you are not in archivelog mode, so it can’t guarantee a consistent snapshot, so it’s asking you to be in read-only mode. Try again in archivelog mode.
