I've been testing the DBCA to clone an existing PDB and noticed this strange behavior:
- Default behavior when the “Create a new administrator” option is not selected:

- The “Create a new admin” option was selected and a password was provided, then the “Create a new admin” option was unchecked again:

3) Workaround
- Click in the “Create a new administrator” option
- Provide any password
- Click in “Next”
- Click in “No” to cancel
- Uncheck the “Create a new administrator” option
- Click in “Next”
Now, we can proceed with PDB cloning without creating a new administrator


This looks like a bug to me.
DBCA version:
$ dbca -version
