Home -> Community -> Mailing Lists -> Oracle-L -> Re: Linux Memory Accounting
Thanks, though I think you knew what I meant. :)
To be more precise in what I am asking:
According to the ps man page:
rss RSS resident set size, the non-swapped physical memory that a task has used (in kiloBytes).
(alias rssize, rsz).
What's interesting is that summing RSS for all Oracle processes on the server in question (RH ES 4 64 Bit) yield 25 gig of RAM.
The server has only 12 gig of RAM.
Here's the ps command:
ps -fywluoracle | awk '{ mem=mem+$8 } END{ mem=mem*1024; print "bytes: ", mem}'
My question is: Does someone here know what is really being reported by RSS? Or is it just untrustworthy?
