What's your OS?
Find out which files belong to your database; query
datafiles, logs and controlfiles. Possibly tempfile,
depending on the version of your oracle, and wither
you use 'em or not.
Shut down your instance; backup all files you found
in the previous step, and the password file.
I assume you already have a backup of the oracle environment, or take it as a calculated risk not to backup, but reinstall.
Or: fire up rman and backup database. rman allows for incremental backups; the above method is not.
More details (lots of 'em...) on e.g. OTN (otn.oracle.com) or Dizwell (http://www.dizwell.com/html/backup.html)
