The pricing must be improved.

Oracle Database Cloud Service could improve by adding some cross-region replication features.

In a future version release, they should add failover features.

There is always an issue when we configure different products in Oracle. Oracle should work on the solution's compatibility issues with the operating system.

It would be nice to have a data dictionary reporting feature in the solution. 

Oracle’s support services need improvement. The process of sharing information between PDBs within the Container Database could be better. 

Oracle Database Cloud Service is a good engine and at the moment, there isn't any new feature I can think of that I'd like added to the service. The only problem I see in Oracle Database Cloud Service is it's more commercial, so it has a relation to how it deals with customers. I don't feel secure in a deal with Oracle because that team changes the conditions each year, and there's no representative from the team that talks to my company about new needs. Oracle needs to improve its relationship with customers and partners in general.

I think the program is rather expensive, so I would like to see it becoming more affordable.
