How to change project.max-shm-memory in solaris

Hi,

We have existing entry in /etc/project and we want to increase it since we added physical memory in the server.

Please advise how to increase project.max-shm-memory from 24 to 40GB, and do we need to reboot the server?

Server: Solaris 10

/etc/project:

group.dba:101::::project.max-shm-memory=(priv,25769803776,deny);project.max-shm-ids=(priv,640,deny);project.max-sem-ids=(priv,4096,deny);process.max-sem-nsems=(priv,5120,deny);process.max-sem-ops=(priv,100,deny);process.max-msg-qbytes=(priv,65535,deny);project.max-msg-ids=(priv,128,deny);process.max-msg-messages=(priv,256,deny)

# prctl -n project.max-shm-memory -i project group.dba
project: 101: group.dba
