Reduced Memory System Simulator utility

[Chuck Lackey]

Is there a function or utility in HP-UX 11.23 for reduced memory simulation testing similar to the AIX 5.3 utility 'rmss?' If there is, I can't find it.

Thanks,
Chuck

Nothing like rmss on HP-UX. However, the attached program can grab any amount of RAM, write some data into the malloc'ed area and then just sit there. Now that isn't exactly the same situation as removing memory from the kernel. What happens is pretty simple. When processes try to run and there isn't enough RAM, low priority processes will be deactivated and then paged out to swap space. vmstat will show the page out rate.

You may find HP's Glance tool useful to monitor memory usage and performance.

Thanks, Bill. That's what I thought...and I'll pass the utility along to the development team to see if they find it useful for their testing.
