I'm an Oracle newbie. I have used Oracle SQL from client applications, but am now learning how to actually administer Oracle.

I installed the 9i Enterprise Edition with a default database. I know that there is a lot of example data in there and I don't really want it in there. Can anyone tell me what schema objects, users, etc... are okay to delete from this example database?

I want to use this database to work off of for learning purposes, but the default install takes up lots of space. I could drop that database, and create another, but I want to use this one in the meantime while I am learning the in/outs of Oracle.

Thanks in Advance....
