below info from the Veritas NetBackup Backup Planning and Performance Tuning 
Guide UNIX, Windows, and Linux Release 6.0

Parameters obsolete in Solaris 10
The parameters below are obsolete in Solaris 10. Although they can be included
in the Solaris /etc/system file and are used to initialize the default resource
control values, Sun does not recommend their use in Solaris 10.
semsys:seminfo_semmns
semsys:seminfo_semvmx
semsys:seminfo_semmnu
semsys:seminfo_semaem
semsys:seminfo_semume
semsys:seminfo_semusz
semsys:seminfo_semmap
shmsys:shminfo_shmseg
shmsys:shminfo_shmmin
msgsys:msginfo_msgmap
msgsys:msginfo_msgseg
msgsys:msginfo_msgssz
msgsys:msginfo_msgmax

[quote="Dominik Pietrzykowski"]Just a note that you shouldn't use the Solaris 
kernel settings for Sol 10
because the default value is much bigger.

Eg shmsys:shminfo_shmmax

On Solaris 10 it will default to 1/4 of physical memory which is pretty good
on all the new boxes running Sol 10.
