hp-ux 11.31 show "real" memory usage?

Hi,

You should use the latest version of kmeminfo tool. The output which you provided is not the actual one.

Not possible to come to a conclusion with this output. But from my experience kmeminfo is the great tool to analyse physical memory usage.

You can get the tool from HP if you could contact them.

No -- you know that you have 3Gb laying around idle that another SAP could use... and you have 45% of memory (50% max - 5% min) which SAP can contend for. That won't cause paging [swapping is when processes are deactivated and should only happen under critically low memory situations] per se -- if the file-backed pages are unmodified, they'll just be dropped. If they were modified, they have to be sync'd eventually anyway.

A trivial way to test the effect of raising your workload by N Gb is to write a program with mlock privileges, allocate N Gb and mlock it -- then look at swapinfo (is any swap actually used), po in vmstat (may get a spike since UFC pageouts count, but should settle down), etc. But in essence -- the memory between max and min is available and fairly easily reclaimable for new workloads. No promises that less memory available for filecache won't affect performance of the system aftwerwards, of course if there's a lot of file I/O involved in said workloads.

Did you try using glance. Glace give you much moe detailed information.

Does you system has any zombi's ?

>UVK: Does you system has any zombies?

Why do you care? They don't take memory/CPU resources.

Hi!

I do not have glance installed.

I will contact HP support for latest kmeminfo tool.
