This is how you can identify memory growth per process
The file mem1 contains the pid and rss and vsz values.
After a couple of minutes do it again but this time to file mem2
Now you can compare mem1 and mem2.
A helpful command is

Hi all,
I tried to output memory usage information while the process is
executing at a particular time. I found out some people
suggesting calling the ioctl. I followed it and wrote a test example:

#include <stdlib.h>
#include <iostream.h>
#include <fcntl.h>

Hi Guys,
I work on a AIX environment and I'm trying to write a script where I can collect all the memory used by a process. Basically I'm executing the command 'ps -fu userid' to get all the process ids and then executing the 'ps v PID' to get all the memory allocated by PPID. My question is... (2 Replies)

Hi all,
I am currently having trouble to get nmon to print me the actual CPU usage for an interval for a process.
According to the manual, something like

Hello Friends,
I need to check memory usage & availability before I could run a program if there is enough memory is left or not, so how could i achieve this? Which command output i should rely on? I have diplayed outputs of SAR, VMstat and PRstat commands below, But how could i check memory... (8 Replies)
hi all gurus:
I want to find out Solaris process memory usage, but got a bit confused, see if any one can provide me some guidance.

rcapd
rcapd(1M) System Administration Commands rcapd(1M)NAME
rcapd - resource cap enforcement daemon
SYNOPSIS
rcapd [-d]
DESCRIPTION
The rcapd daemon enforces resource caps on collections of processes. Per-project and per-zone physical memory caps are supported. For
information about projects, see project(4). For zones information, see zones(5)
When the resident set size (RSS) of a collection of processes exceeds its cap, rcapd takes action and reduces the RSS of the collection.
The virtual memory system divides physical memory into segments known as pages. To read data from a file into memory, the virtual memory
system reads in individual pages. To reduce resource consumption, the daemon can page out, or relocate, infrequently used pages to an area
outside of physical memory.
In the project file, caps are defined for projects that have positive values for the following project attribute:
rcap.max-rss The total amount of physical memory, in bytes, that is available to the project's member processes
See project(4) for a description of project attributes.
For a system with one or more zones, you can dynamically set the rcap.max-rss value for a zone with rcapadm(1M). To set a persistent cap on
memory usage within a zone, you use zonecfg(1M).
You configure rcapd through the use of rcapadm(1M). The daemon can be monitored with rcapstat(1). Configuration changes are incorporated
into rcapd by sending it SIGHUP (see kill(1)), or according to the configuration interval (see rcapadm(1M)).
OPTIONS
The following option is supported:
-d Enable debug mode. Messages are displayed on the invoking user's terminal.
EXAMPLES
Example 1 Setting Resident Set Size Cap Attribute
The following line in the /etc/project database sets an RSS cap of 1073741824 bytes for a project named foo.
foo:100::foo,root::rcap.max-rss=10737418240
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
2 Invalid command-line options were specified.
FILES
/etc/project Project database.

Solaris Zones
NOTES
If killed with SIGKILL, rcapd can leave processes in a stopped state. Use SIGTERM to cause rcapd to terminate properly.
A collection's RSS can exceed its cap for some time before the cap is enforced, even if sufficient pageable memory is available. This
period of time can be reduced by shortening the RSS sampling interval with rcapadm.
The rcapd service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/rcap:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
