First off: you could have looked it up by searching the forum, for example here, post #6, if you didn't want to read the man page where the various options to ps are also explained. No problem, i will write it down once again:

Code:
ps -Alo pid,vsz,args

"pid" gives the process number, "vsz" the virtual memory used by the process, "args" the commandline used to start the process. Add/rearrange columns for your needs. You will also find some other useful commands to gather information about memory usage in this thread. Especially the output of vmo -a would be interesting.

Your systems are both not swapping (although one uses a very small fraction of the swap) but you can anticipate beginning swap activity even before it happens: issue vmstat -vs and have a look at the number of "revolutions of the clock hand" (or similar - i can't access an AIX system right now). This is the number of times the free memory page scanner has already searched the whole memory for free pages. The faster this number grows the nearer the system gets to the point where actual swapping starts.

And a last tip: when issuing vmstat you should use the -w option always. You will get a neatly formatted table again this way.

I hope this helps.

wincache_fcache_meminfo - Retrieves information about file cache memory usage

SYNOPSIS
array wincache_fcache_meminfo (void ) DESCRIPTION
Retrieves information about memory usage by file cache. RETURN VALUES
Array of meta data about file cache memory usage or FALSE on failure The array returned by this function contains the following elements: o memory_total - amount of memory in bytes allocated for the file cache o memory_free - amount of free memory in bytes available for the file cache o num_used_blks - number of memory blocks used by the file cache o num_free_blks - number of free memory blocks available for the file cache o memory_overhead - amount of memory in bytes used for the file cache internal structures EXAMPLES
Example #1 A wincache_fcache_meminfo(3) example <pre> <?php print_r(wincache_fcache_meminfo()); ?> </pre> The above example will output: Array ( [memory_total] => 134217728 [memory_free] => 131339120 [num_used_blks] => 361 [num_free_blks] => 3 [memory_overhead] => 5856 ) SEE ALSO
