Hi,

I'm just wondering how Solaris 7 (on Sun Ultra10)handles memory
intensive applications, i.e. what happens when it runs out of physical
memory?.... does it use the hard-drive?... basically does it handle
memory the same as any other O/S, e.g. win9x. Thanks.

There's a good overview at
http://www.sun.com/sun-on-net/performance.html. Look for the "Solaris
Memory Sizing White Paper" by Richard McDougall.

There's also a new link on that page to a 'Solaris 7 Memory Statistics
binary' that sounds interesting. Haven't tried it myself.

HI
well if you've finished reading Jim's suggestion on Sunworld you'll see
that yes Solaris does use a swap file to instigate virtual memory, as do
all Unix varients. At the base level it handles memory more like NT (but
alot better before I get flames:-) in that each processes memory is
protected from other processes, unlike 95 where one process can stomp
over another's memory which is why 95 is less stable than NT.

It handles memory in a much better fashion than win9x. Yes Solaris will
use swap(read /tmp), located on your hard drive, when it runs out of
physical memory. In fact all memory is seen as the same, from an
application point of view, weather it is real or virtual.

To Learn more check out Unix Internals, I forget who the author is but it
will tell you pretty much everything you want to know about what goes on
in Unix.
