Hi.

You have your undo tablespace called undotbs_01 but your init.ora parameter undo_tablespace = undotbs. This should be undotbs_01.

Yes, the sizing was missing since it was only a small section of the create database command. I've added it in now to save any further confusion. Of course, if your using OMF you don't need the size or the file path to be specified.

If you use the Database Configuration Assistant (DBCA) you can get it to save the creation script rather than run it. You will then see exactly what the statement should look like.

Cheers
