Change hostid for software install - license issue

UNIX Solaris

Hi all.
Solaris 9.

After I change the hostid, how can I change it back without rebooting the machine?

Thanks

The normal route would be to get a new license from the software vendors if you have had to change the host running the license server, just as you would each time you upgrade the software.
