Pinning/Locking memory on HP-UX v11

[Alexander Russell]

Please, can anybody tell me whether it is possible to lock memory (aka pin memory) on HP-UX. I have 4GB of real memory and would like to either disable memory before IPL (can I disable at a greater granularity than the memory cards I have installed, say 1MB at a time?), or disable memory by pinning it at the O/S level?

I am hoping to be able to reduce the amount of free physical memory available on my HP-UX box, until other processes start paging out.

This is because the virtual memory system does not page out non-dirty pages, so when my processes is paged back in again it is smaller, and I get an idea of how much memory my processes is really using, as opposed to how much it is given on execution by the O/S (or how much it asks for--and then perhaps doesn't use all of).
