Re: Not allowing a process to swap from physical mem to swap
It can only be done in the code i think. It needs to alocate lockable memory. This memory cannot be swaped out.
What you can do is install PRM v >2. You can configure memory usage and "CAPPING" by a PRM group. Check http://docs.hp.com for PRM configuration.
Hope this will help,
Gideon

Re: Not allowing a process to swap from physical mem to swap
I believe you need to look up the
plock() & mlock()
system calls.
Do a
man 2 plock or mlock
for further details.

Re: Not allowing a process to swap from physical mem to swap
The process could have hung, therefore not be runnable, and then have been paged out as other runnable processes needed memory. But when you examined it, it's already paged out so it appears that it hung because of paging out. You may have the timeline reversed here: subprocess hangs, then it gets paged out.
Just a thought...
