In this post, we shall create a new database using DBCA and will see if there are any changes in that.
To start with, let’s start the DBCA
DBCA initializes and the welcome screen appears.
When we proceed next, though we shall see choose the option of creating database using advanced configuration, we can see the first change that option to uncheck the database being a multi-tenant is no longer available. So from 21c, new database must be multi-tenant databases.
We proceed with the screens giving the inputs.
Next change is that now, the option to select the creation of sample schemas is not available.
And finally, we have the database created.
So, there are not many changes in the DBCA except two that I mentioned. We shall keep on exploring 21c database in the next posts.
Hope that helps.
