Hi,
I'm just starting with Digital UNix, so sorry if I'm asking
somthing stupid...
I have a customer trying to configure his system to run Oracle.
Oracle asks for a number of parameters to be set on SYSCONFIGTAB.
We were able to upgrade all of them fine, except for MSG_MNI and
SEM_MNI. Oracle asks for 1024 for both of them, but the maximum I can
set them to is: MSG-MNI=128 and SEM-MNI=256.
The question is: Do those limits depends on any other parameter???
Thanks in advance
Claudia

Hi Claudia
Both these parameters seem to be 32-bit signed integers, so I'd expect
you would be able to set the values you require. I don't thnk they
depend on anything else.
/*
* Semaphore information structure.
*/
struct seminfo {
int semmni, /* # of semaphore identifiers */
:
/*
* Message information structure.
*/
struct msginfo {
int msgmax, /* max message size */
msgmnb, /* max # bytes on queue */
msgmni, /* # of message queue identifiers */

What happens when you try to set them higher? How do you verify the
values?

I wasn't sure because I usually set a whole bunch of ipc parameters
when I set a machine up for Oracle. So I put
ipc:
msg-mni=2048
sem-mni=2048
(and no other ipc settings) into the sysconfigtab of my 4.0B system and
rebooted. Just as I expected:
sysconfig -q ipc | grep mni
msg-mni = 2048
shm-mni = 128
sem-mni = 2048
That pretty much rules out dependencies of msg-mni and sem-mni on other
(at least ipc) parameters. The question from .1 remains: what happens
if you set the parameters larger than the max you are currently seeing?
Does the machine spit out any comments on the console about parameters
which are not accepted?
