I'm trying to figure how much memory per process is using?
I think it's the TRS column x 4k (127800 x 4).
Am I right? Any advice is greatly appreciated.
Code:
PID TTY STAT TIME PGIN SIZE RSS LIM TSIZ TRS %CPU %MEM COMMAND
753726 - A 13:01 0 154100 281900 xx 88783 127800 7.4 2.0 aaaa
975236 - A 12:40 0 179268 307068 xx 88783 127800 7.2 2.0 bbbb
934076 - A 12:31 0 173252 301052 xx 88783 127800 7.1 2.0 cccc
651342 - A 12:38 0 154136 281936 xx 88783 127800 7.1 2.0 dddd
840036 - A 1:02 0 18332 146132 xx 88783 127800 0.6 1.0 eeee
954714 - A 0:55 0 19776 147576 xx 88783 127800 0.5 1.0 ffff
942566 - A 0:57 0 17500 145300 xx 88783 127800 0.5 1.0 gggg
663972 - A 0:56 0 19840 147640 xx 88783 127800 0.5 1.0 hhhh

Having so many posts, you should be already familiar using code tags - you got a PM with a guide how to do that. Some less font formattings would be ok too, thank you.
Hello all,
I would be happy if any one could help me with a shell script that would determine all the processes running on a Unix server and post a mail if any of the process is not running or aborted.
Thanks in advance

Hi All,
I have a process running on my AIX 5.3 server box. The process runs fine for 5-6days but then crashes. The log file shows malloc failure and the svmon (Virtual memory size), ps -lef (SZ value) are also gradually increasing. But unfortunately MALLOCDEBUG and any other memory debugging... (3 Replies)
Can someone please help me with a script that will help in identifying the CPU & memory usage by a process name, rather than a process id.This is to primarily analyze the consumption of resources, for performance tweaking.

Hi Experts,
Our servers running Solaris 10 with SAP Application. The memory utilization always >90%, but the process on SAP is too less even nothing.
Why memory utilization on solaris always looks high?

I want to write a shellscript which determines if a particular process is long running than my specified threshold time.

Hi,
This thread has been posted before on linuxquestions.org, but no answer, maybe because this is unix question and not linux.

Hi,
Below is the code snippet I use on Linux (Centos) to retrieve the Process Name, PID and memory consumed on Linux (Centos) host:-
top -b -n 1 | awk -v date="$tdydate" -v ip="$ip" 'NR>7 {print date","ip","$12,","$1,","$10}'
Any idea how the same can be retrieved on an AIX host? This... (1 Reply)
Hi Experts,
I am facing one problem here which is one process always stuck in running state which causes the other similar process to sleep state . This causes my system in hanged state.
On doing cat /proc/<pid>wchan showing the "__init_begin" in the output.
Can you please help me here... (0 Replies)

Team,
I have multiple batchjobs running in VM, if I do ps -ef |grep java or tomcat I am getting multiple process list.
How do I get my exact tomcat process running and that is unique? via shell script? (4 Replies)

posix_madvise
posix_madvise(3C) Standard C Library Functions posix_madvise(3C)NAME
posix_madvise - memory advisory information
SYNOPSIS
#include <sys/mman.h>
int posix_madvise(void *addr, size_t len, int advice);
DESCRIPTION
The posix_madvise() function advises the system on the expected behavior of the application with respect to the data in the memory starting
at address addr, and continuing for len bytes. The system may use this information to optimize handling of the specified data. The
posix_madvise() function has no effect on the semantics of access to memory in the specified range, although it may affect the performance
of access.
The advice to be applied to the memory range is specified by the advice parameter and may be one of the following values:
POSIX_MADV_NORMAL Specifies that the application has no advice to give on its behavior with respect to the specified range. It is
the default characteristic if no advice is given for a range of memory.
POSIX_MADV_SEQUENTIAL Specifies that the application expects to access the specified range sequentially from lower addresses to higher
addresses.
POSIX_MADV_RANDOM Specifies that the application expects to access the specified range in a random order.
POSIX_MADV_WILLNEED Specifies that the application expects to access the specified range in the near future.
POSIX_MADV_DONTNEED Specifies that the application expects that it will not access the specified range in the near future.
These values are defined in <sys/mman.h>
RETURN VALUES
Upon successful completion, posix_madvise() returns zero. Otherwise, an error number is returned to indicate the error.
ERRORS
The posix_madvise() function will fail if:
EINVAL The value of advice is invalid.
ENOMEM Addresses in the range starting at addr and continuing for len bytes are partly or completely outside the range allowed for the
address space of the calling process.
The posix_madvise() function may fail if:
EINVAL The value of len is zero.
