People,
This is more of a correction to one of my
old posts:
I believe I have previously posted that
you should not put any tuning parameters in /etc/system for solaris 10
Turns out I am wrong, if you have a busy
media server and it gets shared memory allocation errors (89s), I recommend
the following:
set
shmsys:shminfo_shmmni=256
or:
set shmsys:shminfo_shmmni=512
here’s the technote:

Thanks go to Brook from support who helped
me out on this one.
You may also need to play around with
projmod, which is whay I originally thought you don’t need /etc/system
anymore. Also when you read the Sun docs that’s the impression you get
but in practice it’s not 100% true.
Here’s some prctl output from our
emdia server:
project.max-shm-memory
privileged 16.0GB
-
deny
-
system
16.0EB max
deny
-
project.max-shm-ids
privileged
512 -

-
system
16.8M max

Any questions, shoot me a mail.
