Question
New Schema
Hi,
I have a production database schema (called it Live) which currently running live on the server.
Question 1:
My question is how to duplicate this production database schema into another schema (called it Test) with same table structures, view, procedure, users, etc.
The purpose is to have another schema for user to do the testing instead of testing the production database schema.
Question 2:
Can i have this Test schema reside in the same server as production database?
Question 3:
Where can I get the Command/Guide/Solution to get this job done.
Please advice and help.
Thanks.

Create a new test database. Export data from Prod database and import into Test. You wouldn't be able to have the same table names w/in the same database, even if it is in a different schema. Plus, it's always best practice to keep Test and Production Data separated.
Take a look at the Utilities Section in the Oracle Documentation for the command options for Export/Import. Or type Exp Help=y or Imp Help=y at the command prompt.

1. You can export the whole user (if this is what you referenced by schema) with the export utility.
Create your testdata base and the user and import the dmp as the new user (See keywords FROMUSER and TOUSER in the docs if the names do not match).
2. Yes and no. The roles (if you use them) are shared over all schemas. You cannot create a role more than once in a server. I have heard about 9i that there is a virtual server option, but I wouldn't use it to create a test-DB within a production environment. If performance is not too critical I would go for creation of a new DB on the same machine.
3. The manual contain most of the commands with an example about their invocation. The complete sequence of statements you need depends very much on your actual enviroment.
