reserved memory

Peter Budai_1 — Fri, 01 Dec 2000 09:53:04 GMT

Hi !

When I run swapinfo on my system (HP-UX 11, 2GB RAM, 4 x 1GB device swap), it tells me that 1.7GB of memory is "reserved". I think, it is reserved, but not allocated from the swap by running processes, and it will never be used.

Question: how I can find out, which process reserve how much memory and how I can change this ?

Thanks

The reserve figure is the total memory used by currently running processes which is unlocked - ie. these processes can be paged out if needed. So you currently have 1.7Gb used by currently running processes.

If you want to find out who is using what memory use ps -el and look at the SZ column, or use glance or top. Also use ipcs -ma to see who is using what amount of shared memory.

Check the online manual on your system for swapinfo(man swapinfo).
