/etc/system changes for 8.0.5 on Solaris7

Hello,
  I have installed Oracle 8.0.5 EE on Solaris7. The install docs give some minimum settings to be placed in /etc/system regarding Shared Memory. I'm new to Unix AND Oracle, and haven't been able to find too many resources to help me with this piece of the configuration. I ended up adding the recommended minimum settings:

set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
set semsys:seminfo_semmns=200
set semsys:seminfo_semmni=100

 However, I have since seen some posts say that SHMMAX shouldn't be larger than my physical memory (which is 512 Mb). So now I'm confused - Is Oracle suggesting that I need to have 4Gb of physical memory installed to meet their minimum requirements? Is SHMMAX based on virtual addressing? If I lower SHMMAX to 524288000 (if my math is right), should any of the other setting be adjusted?

  I wanted to take Oracle's O8 on Solaris class, but they have about 7 prerequisite classes, which I just don't have the time (or budget) to take within the next month.

Thanks for any help
