Remidata and Nomthie:
Thanks a lot for your replies.
As Remidata told me, I have created a new user account, then I logged
in with that new user and could create new tables on that new schema.
Here some new questions about this.
1) I am from DB2 world, so the structure that I have in mind is.
Instance -> database -> Schema -> Table.
So Remidata, with OrXpress I can only create new schemas in existing XE database?
2) I have read what Nomthie said and what I understood is that I must
shutdown database named XE in order to have a new one.?
When I go to SQL Tool and I submit the command:
"create database oratest" it shows the following errors.
ORA-01501: CREATE DATABASE has failed
ORA-01100: database already mounted.
What does it mean?.
Thanks in advance....
