Rafal Grzegorczyk Thanks for your response! My question is: what user do you use for these connections? A proxy user would work, but then this user needs to have all object priviliges to all schemas included in the SQLcl projects project. And if a new object is created, this has to be granted to get the projects export working... so that's why I'm wondering if you use SYS as user for your "Dev admin" connection?!

Michael Abele dev_admin is an ADMIN user at OCI, so it will always have the required grants. For exports, you should always use a user who has the privileges required for the schemas included in the project. For OCI, it can be ADMIN, for non-premise, it could be a user with a role assigned ( and that role should have everything required). Basically, is up to you.

Rafal Grzegorczyk thanks a lot for your detailed explanation!
