====================
Question:
1.How about my hp-unix system running status
2.why free memory large than real size

You'll get a cleaner output with -f filename.
free may be talking about virtual memory?

[Don Morris_1 · Accepted solution]

No, free is physical memory (at least physical memory available to user space) available.

It is larger than the real portion because real is how much physical memory is in use by User space (not the total physical memory on the entire box). There's nothing odd about that -- this box just has a bunch of RAM hanging around.

As far as Question (1) [Running status]... I don't really know what you're asking. It is running, doesn't seem to be doing all that much (so either you've got bottlenecks beyond belief in your workload or just aren't running much of anything). What in particular are you wondering about it?

Wtianchai,

Try to use Glance -> memory report to see your current status of your memory usage.

Shalom,

When a system is "not" healthy users have a way of letting you know. Usually it begin's with a whiney voice and uses the word "slow"

A good way to check for performance after or before a complaint.
