Here are my notes on the defaults (from Solaris 2.4 admittedly):

set semsys:seminfo_semusz = 96
set semsys:seminfo_semopm = 10
set semsys:seminfo_semume = 10
set semsys:seminfo_semaem = 16384
set semsys:seminfo_semmap = 10
set semsys:seminfo_semvmx = 32767
set semsys:seminfo_semmsl = 25
set semsys:seminfo_semmni = 10
set semsys:seminfo_semmns = 60
set semsys:seminfo_semmnu = 30

set shmsys:shminfo_shmmin = 1
set shmsys:shminfo_shmseg = 6
set shmsys:shminfo_shmmax = 1048576
set shmsys:shminfo_shmmni = 100

Here's the correct syntax.

The solaris FAQ says:

3.52) How can I change the SYSV IPC parameters?

    The following parameters can be used to change the number of
    semaphores, the amount of shared memory and the number of IPC
    messages.  They're set in /etc/system, as usual.

    set semsys:seminfo_semusz = <value>
    set semsys:seminfo_semopm = <value>
    set semsys:seminfo_semume = <value>
    set semsys:seminfo_semaem = <value>
    set semsys:seminfo_semmap = <value>
    set semsys:seminfo_semvmx = <value>
    set semsys:seminfo_semmsl = <value>
    set semsys:seminfo_semmni = <value>
    set semsys:seminfo_semmns = <value>
    set semsys:seminfo_semmnu = <value>

    set shmsys:shminfo_shmmin = <value>
    set shmsys:shminfo_shmseg = <value>
    set shmsys:shminfo_shmmax = <value>
    set shmsys:shminfo_shmmni = <value>

    set msgsys:msginfo_msgseg = <value>
    set msgsys:msginfo_msgssz = <value>
    set msgsys:msginfo_msgtql = <value>
    set msgsys:msginfo_msgmap = <value>
    set msgsys:msginfo_msgmax = <value>
    set msgsys:msginfo_msgmnb = <value>
    set msgsys:msginfo_msgmni = <value>
