Which previlages must I have to allocate table spaces, create other users etc. And How can I log on in order for me top allocate these privalages to my self. I happen to be the System Administrator, and I installed this Oracle by myself. I had two Users SYS and SYSTEM for which oracle asked me to provide passwords, which I did, then I created my own account but I think I did not give myself sufficient privaleges How can I give my self more privalages to perform tasks. I'm new to Oracle Please bear.
