hpux 11i kernel parameter limitation

[Victor Lee]

Hi

I am trying to increase the shmmax kernel parameter on an hpux 11i (or 11.11) system. The system refuses to increase it beyond the 1Gb limit. How can I increase it beyond 1Gb?
shmmax is a "dynamic" kernel parameter.

thx

Here are a couple of links that should help you. Judging from the shmmax page, it appears that you are on a 32-bit system. If that is the case then 1GB is the limit.

hi,
the system os is of 32 bit, which has the limit of shmmax of 1gb. you need to convert 32bit to 64 bit(from the core os cd) and then increase the shmmax

[Vincenzo Restuccia]

shmmax :
Maximum
0x40000000 (1024 Mbytes) on 32-bit systems
Maximum 1 Tbyte on 64-bit systems

Hi

thanks for all your replies. the system is an L3000. when I do "getconf KERNEL_BITS" it says 64. therefore I believe this machine to be a 64 bit machine. how does one increase shmmax on a 64 bit machine? maybe there is some file that contains kernel param limits that I need to edit?

thx

Victor,

I just happened to have an L3000 in house for a couple of days. I tried setting 'shmmax' past 1Gb in sam and I got the same error message. I looked around and found this recent thread from the forum that explains how to get around it. You have to modify a file in /etc/conf/master.d to get past it.

Have fun!

That last link is to the US ITRC site which us Europeans cant get to without the usual logout/login problem which is very annoying. Can some US member please cut and past the info on how to get around this from the link and put it in a reply here please ?

Thanks,

Stefan
