I have two users Bob and Alice in Oracle, both created by running the following commands as sysdba from sqlplus:

   create user $blah identified by $password;
   grant resource, connect, create view to $blah;

I want Bob to have complete access to Alice's schema (that is, all tables), but I'm not sure what grant to run, and whether to run it as sysdba or as Alice.

Happy to hear about any good pointers to reference material as well -- don't seem to be able to get a good answer to this from either the Internet or "Oracle Database 10g The Complete Reference", which is sitting on my desk.
