I have to get an instance of Oracle XE running on my laptop. This is so I can test a plsql package I have been working on at my house. Currently out of the job. I seem to remember when I did this the last time I had to configure the tnsnames.ora and listener.ora files correctly. I would like everything to be as simple as possible. Ex, everything should be named XE or something. I can't even find the listener.ora file actually.

Need a brief walk through over the tnsnames.ora file and the listener.ora files.
