HP-UX memory usage allocation
Hi all,
I have a HP-UX Server with 4 gigabytes of physical RAM. When I use the 'Glance' utility to see what my memory utilization is, my memory usage shows up maxed out at 99%. I shut off all the known processes that I'm running on that box and the memory utilization is still at 78% (with Swap Space Util at 45%). Also, the buffer cache is at 1.5 GB usage.
I am wondering if there is a tool out there that will let me check exactly WHICH PROCESSES is using so much memory. I need the memory allocation breakdown by user processes. (does 'top' suffice?)
What is the buffer cache size? Is that a manual setting in the kernel setting?
thanks for any suggestions!

NAME
unlockable_mem - OBSOLETE kernel tunable parameter
DESCRIPTION
The tunable is obsolete and has been removed.
Memory locking allows the privileged user to specify which pages need to remain in memory, and unaffected by the swap process. This fea-
ture allows you to ensure that memory access times are unaffected by delays introduced by memory paging and swapping. For example, locking
is a tool provided to privileged users on a system that is short on physical memory. Instead of having these privileged processes swap
like the rest of the processes, they can lock portions of their address space. Once the pages are locked in for the privileged processes,
they will no longer have to worry about memory contention. The unprivileged processes however, will have to compete for memory.
provides you with a limiting factor on this privileged behavior, by setting the amount of memory which cannot be locked by user processes.
WARNINGS
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
