I've installed both the 9i Database and Application Server successfully, and now I'm trying to get the Java Pet Store demo to run. One of the things I have to do is create the user estoreuser and grant it both resource and connect. I basically know nothing about 9i except what I've read in a book that helped very little.

What sort of things do I have to do with the database before I can perform these operations. The database installed successfully, but are there any files I have to configure and any operations I need to do once I've installed the database?
