Which Process is using how much Physical Memory in Solaris 8?

If you're hoping to see exact amount of RAM memory pages in use, it may be tough - but you can make some determinations based on how much swap (hard drive partitions and other swap files) is in use.

Try something like -

ps -aefo pid,ppid,pcpu,pmem,vsz,rss,args

first to see if that helps you - pay attention to the virtual size and resident set size to start with - if you're running Oracle (for instance) it has a funky way of operating and all of the Oracle shadow processes will each report a huge vsz and rss though you really only need pay attention to the largest one.

Perhaps someone else has a more elegant solution or tool to do this - but to obtain exactly how much physical RAM is in use hasn't been the most exact science in older versions of solaris. vmstat doesn't show exactly what you're looking for in the freemem column, you could install symbel and see if it gives a better look - jeff

Download or compile the latest version of top.

hi k79

[correction_mode]

top shows memory-usage in summary and also virt (size) and resident for each task

[/correction_mode]

sorry, but found only an older screenshot:http://www.unixtop.org/top-output.gif

would grant top a try. ;-)

[edith_says:]

%MEM is the used physical memory of the task in relation to the entire physical memory

good morning, k79

you need phys. memory for _each_ process, right ?

please take look at the example screenshot: [url]http://www.unixtop.org/top-output.gif[/url]

see column 7, called "RES"

_that is_ the physical memory used by each task.

or do i understand you false ?-(

i agree, that top without options lists his default values sortet to cpu -using tasks, limited to the 24 lines of a standard console.

but using man top, you get all the options to list _all_ task, or e.g. sort by memory using or by user using etc. ;-)

please support me, if i understand you wrong.

greets, jenny
