Kernel Parameters in Solaris 10
Hello,

Can anyone point me out as to how to set the following parameters in Solaris Kernel: set semsys:seminfo_semmni=16384, set semsys:seminfo_semmns=32768,set semsys:seminfo_semmsl=1024,
set semsys:seminfo_semmnu=16384,set semsys:seminfo_semume=1024,
set shmsys:shminfo_shmmax=4294967295,set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=16384,set shmsys:shminfo_shmseg=1024,set msgsys:msginfo_msgmax=65536, set msgsys:msginfo_msgmni=1024,set msgsys:msginfo_msgmnb=524288, set msgsys:msginfo_msgtql=107520, set semsys:seminfo_semopm=250, set semsys:seminfo_semvmx=32767, set maxphys=8388608

my problem is that we had a Solaris 8 server, and now was re-done with Solaris 10, and it has some problems with the print queue, the same issue was on Solaris 8 and the mentioned parameters were the ones configured and fixed the problem...


but my issue would be how to prove to my boss that the kernel parameters are ok, and this way he can focus on the Application side (database maybe??).

So maybe you can help me out with the following two questions:

1.-Is there a way to find out the current parameter values in SOLARIS 10, so that I can compare the current parameter values that I have from the old solaris 8.

2.-Were the OBSOLETE parameters in SOLARIS 10 changed for something else (another type of parameter maybe??) or something that equals them??

I'm kind of new, tried finding some info and this is what I was told but no luck, the os is SOLARIS 10:

Just put these settings in /etc/system, however you probably don't need to set most if not all of them.
They are either removed from or obsolete in Solaris 10.
Checked out the following page and found out that most of the paremeters mentioned are either obsolete or removed in solaris 10. so According to Suns Docs, these are the only ones that are not obsolete: set semsys:seminfo_semmni=16384
set semsys:seminfo_semmsl=1024
set semsys:seminfo_semopm=250

docs.sun.com:

Any idea or suggestion will be helpfull.

Thank you!!
