Solaris 10 : Memory Capping Query
Hi Folks,
Im running solaris 10 8/07 and im trying to set up some memory capping within zones for the system project.
ie.
zone1# cat /etc/project
system:0::::rcap.max-rss=41943040
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
zone2# cat /etc/project
system:0::::rcap.max-rss=31457280
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
Now this seems to to work fine as when I check this Im getting the results I expect to see.
ie
zone1# rcapstat
id project nproc vm rss cap at avgat pg avgpg
0 system 30 192M 84M 40M 37G 0K 11G 0K
zone2# rcapstat
id project nproc vm rss cap at avgat pg avgpg
0 system 30 240M 31M 30M 42G 0K 11G 0K
However, when I check the memory usage of these zones from the global zone I get different results..
root@au11qap1i0tels2 [112] > prstat -n16 -Z
ZONEID NPROC SWAP RSS MEMORY TIME CPU ZONE
5 33 193M 84M 0.5% 0:05:43 0.3% zone1
6 33 240M 71M 0.4% 0:05:43 0.3% zone2
0 68 783M 798M 4.9% 19:05:07 0.0% global
Can someone let me know if this is a quirk with the way the rcapd communicates with the global zone ? or is something not right here ?
Thanx in advance.

Hi,
I'm running a multi-process software system on a Solaris 8 machine. When I monitor the memory usage, I see that the free memory is dropping rapidly, but I can't detect a process that uses this memory.
I'm using "top" to get the free memory and the memory usage of processes.
Thanks. (3 Replies)

Hi all
I've purchased a T3-1 server. The T3-1 has a 16 core CPU. I want to create a zone to install an Oracle DB server in. Due to Oracle licensing issues I want to limit the zone to 8 cores. I've done some research and it seems there are 2 ways of setting a CPU core limit for a zone.

NAME
install-solaris - install the Solaris operating system
SYNOPSIS
install-solaris
install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation,
install-solaris invokes either a text-based installer or a graphical installer.
The following minimum requirements for physical memory dictate which features are available during installation:
For SPARC machines:
128 MB
Minimum physical memory for all installation types
128 MB
Minimum physical memory required for windowing system
384 MB
Minimum physical memory required for graphical-based installation
For x86 machines:
256 MB
Minimum physical memory for all installation types
256 MB
Minimum physical memory required for windowing system
512 MB
Minimum physical memory required for graphical-based installation
In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea-
tures available.
install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more
details.
install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
