kernel parameters

I got an answer before getting a copy of my own posting.
ORIGINAL QUESTION
Hello everybody?
I was requested to modify the kernel parameters for oracle.
OS: Solaris 2.5.1 with recommended patches, on an E6000.
I added the following lines to the /etc/system:
*
*
* Variables for Oracle
set shmsys:shminfo_shmmax=134217728
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=150
set shmsys:shminfo_shmseg=10
set semsys:seminfo_semmns=2500
set semsys:seminfo_semmni=750
set semsys:seminfo_semmsl=300
set semsys:seminfo_semmap=750
set semsys:seminfo_semmnu=2500
set msgsys:msginfo_msgmap=1000
set msgsys:msginfo_msgmax=2048
set msgsys:msginfo_msgmni=600
set msgsys:msginfo_msgssz=8
set msgsys:msginfo_msgtql=1000
After rebooting the machine, the output from sysdef -i looks like this:
*
* IPC Messages
*
0 entries in msg map (MSGMAP)
0 max message size (MSGMAX)
0 max bytes on queue (MSGMNB)
0 message queue identifiers (MSGMNI)
0 message segment size (MSGSSZ)
0 system message headers (MSGTQL)
0 message segments (MSGSEG)
*
* IPC Shared Memory
*
0 max shared memory segment size (SHMMAX)
0 min shared memory segment size (SHMMIN)
0 shared memory identifiers (SHMMNI)
0 max attached shm segments per process (SHMSEG)
*
Why the Shared Memory and the Messages parameters turned into 0??
What am I doing wrong?
ANSWER:
>From Jeff Waskilko:
"shared memory isn't initialized until it's used. Once you start
your database, you'll see the proper values reported."
The same happens with the rest of the parameters.
THANKS:
Thanks for their answer to:
Jeff Wasilko <jeffw@smoe.org>
Charlie Mengler <charliem@anchorchips.com>
and to the rest of the people whose answers are still on
their way.
