9i install Solaris mount points?

I have spent the past two nights working on my first Oracle install, on Solaris 5.9. Simple install, one disk on one SUN Blade 100. This install will be used to learn Oracle hands on in preparation for Oracle certification. One of my questions involves the mount points. I understand this is a customary Solaris mount point, a directory. My question is where do I make the directory(s) /u01 /u02 etc. Absolute pathnames names would be most helpful. From my reading on the net it seems I might just need one mount point. Please advise me regarding the mount points. Again this is a non production install that will have little use. Performance is not a concern. Thank you in advance for your help. Please keep in mind this is my first install, verbose responses welcome.
