Solaris10 resource control - max-shm-memory

The DBAs have asked to configure a Sol10 system with 4GB of shared
memory for Oracle.
Unlike in Sol8 where I made the changes to /etc/system
       (set shmsys:shminfo_shmmax=4294967295)
Sol10 requires me to make config changes to /etc/project. I'm not too
up on Sol10 and have plagiarized the following from some docs.
      /usr/sbin/projadd -c 'Oracle User' 'user.oracle'
      /usr/sbin/projmod -s -K 'project.max-sem-ids=(priv,500,deny);project.max-shm-memory=(priv,4GB,deny)' user.oracle

My question is this:
Are all processes (user 'oracle') running under this
project entitled each to 4GB of shared mem or is the combined usage of
shared mem by all oracle processes limited by the 4GB ?

Thanks,
George
