Finding Memory Utilisation

Hi
I need to find memory utilisation using my java program.??
Heard about runtime class total memory and free memory but I think it returns that of JVM.
I dont want JVM's memory utilisation but the memory utilisation of the system.
Any suggestions for finding the above.

Guyss...any answers...

Find memory leak

Hi All ,
In our SAP application server (Solaris 10 X86 running on hardware HP ProLiant BL685c G5) physical memory available is day to day decreasing drastically. We suspect, there is a memory leak.
Could you please let us know how to find memory leak in Solaris.
Regards,
Rajesh.

Hi Rajesh
Memory leaks have a large number of possible causes, including:
•Unsupported hardware or software
•Custom Scripting
•Misconfiguration
•Third party hardware and software issues
The prstat command can be used to gather basic performance data to help identify if there are any processes consuming a large amount of memory. For example, the data below is sorted by the SIZE column. SIZE is the total virtual memory size of the process:
prstat -s size
If you are experiencing some of the symptoms described above or if you suspect a memory leak, it is particularly important that performance data is captured so the memory leak can be confirmed. It is important to gather at least the following pieces of information:
•Process ID (PID)
•Size of the process
•The executing command
•The timestamp information showing exactly when the data was captured.
while true
do
for pid in `cat pids`
do var=`date|cut -d' ' -f4`
echo "$var :\c" >> ps.log.$pid
ps -eo pid,vsz,rss,pcpu,args | grep $pid |grep -v grep >> ps.log.$pid
done
sleep 30
done
You could check the memory utilisation details through
#mdb -k
::memstat

Code for finding CPU utilisation for executing query

Hi, i need code for finding CPU utilisation for executing the particular query.

Use session tracing, then in trace file you can find cpu utilization for particular statement on each phase: parse, execute, fetch and the overall.
Or You can use the dbms_utility.get_cpu_time (if your database is 10g) in pl/sql:
declare
cpt1 pls_integer;
cpt2 pls_integer;
cputime pls_integer;
begin
cpt1:=sys.dbms_utility.get_cpu_time;
<some code here>
cpt2:=sys.dbms_utility.get_cpu_time;
cputime:=cpt2-cpt1;
end;
good luck

Reducing the memory utilisation of my database

Hi,
I want to reduce the memory utilisation of my database. I want to know which sqls have assigned by the oracle some OS memory in my database.I have the awr reports with me.
My questions:
1.Which section of the awr will give exactly this information?
(SQL ordered by Sharable Memory doesn't help )
2. Or can you tell me some views or tables wherein I get the needed the information which I can query against in my database?
3. How can I reduce the memory utilisation in case I get the problematic sqls?
Thanks,
Sach

I'm not sure that I understand your question. Can you clarify a couple points for me?
What memory are we talking about here? Normally, most of the RAM allocated to Oracle is going to be SGA. But SGA isn't associated with any particular SQL statement, at least not in a fashion that I could contemplate doing reporting on. Individual SQL statements require RAM temporarily in the PGA during execution, but it sounds like you're not interested in that.
What is the problem you are trying to solve here? If you want to reduce the amount of RAM allocated to Oracle from the operating system, you should be able to do that without analyzing any specific SQL statements by adjusting memory parameters. Mentioning what version of Oracle, what parameters you've set, and how much you'd like to reduce memory consumption would be helpful if you want specific suggestions for parameters to change.
What does "problematic sqls" mean in this context?

Finding Memory leaks in C using Visual Studio 2013

I am using Visual Studio 2013, and taking a course in C programming and we started
talking about memory bugs detaction, in particular memory leaks, and how to detect them using Valgrind on Linux.
I want to know if there is a way to detect such memory leaks using VS 2013. I tried searching online but it just leads to lots of articles and blogs and msdn posts and blogs with lots of words like dump files, and analyzing them, etc which is weird
because:
1) It sounds so complex, convoluted and unintuitive it is actually hard to comprehend it.
2) The main reason this is weird is due to the fact that VS is the most advanced IDE around and Microsoft spends so much money on in, yet from what I have read it seems that there is no simple way to use VS to detect memory leaks
- certainly no way that's as simple as Valgrind where I only have to compile the program and run the command valgrind -leaks-check=yes ProgramName
and it simply prints to me all location it thinks there is a memory leak and describes the error (like not freeing memory after allocating it with malloc hence having "dead" memory after the program finishes, or accessing memory that's out of
the array bounds)
So my question is how to use VS 2013 in order to achieve the same results and to find out First in high level if there are memory leaks in the program, and Second - to detect in a simple manner where those leaks are- preferably without involving dump files
(not that I know how to use them anyway in VS).

Hi MicrosoftLaw,
Thanks for your post.
Based on your issue, if you want to check if there are memory leaks in the C program from this VS2013. I suggest you could try to find Memory Leaks Using the CRT Library, for more information:
https://msdn.microsoft.com/en-us/library/x98tx3cf.aspx?f=255&MSPPError=-2147217396
In addition, I find a similar thread about this issue, please you refer the Dusty's suggestion to check this issue.
http://stackoverflow.com/questions/45627/how-do-you-detect-avoid-memory-leaks-in-your-unmanaged-code
I did some research about this issue, I found that the Visual Leak Detector extension tool is a free, robust, open-source memory leak detection system for Visual C++. So if possible, I suggest you could try to use the Visual Leak Detector extension
tool to find the memory leak for Visual C/ C++ program.
https://visualstudiogallery.msdn.microsoft.com/7c40a5d8-dd35-4019-a2af-cb1403f5939c
However, if you have any issue about how to use this Visual Leak Detector extension tool to find the memory leak for C program. I suggest you could directly to write a review to this REVIEW tab in Visual Leak Detector site.

Finding memory leaks in java

Hello,
I have a memory leak in my application. I have found other memory leaks in the software using JProfiler, but I have a problem with JProfiler finding this one. My biggest problem is the JProfiler itself. If I use short runs, the JProfiler works fine. If I run my application for more than half a day, the JProfiler eats up memory and after a while it stops responding.
I tried JProbe, but after profiling my application for 18 hours straight, it got buggy and wouldn't work correctly. It also ate up alot of memory, and couldn't process my snapshot after 18 hours of run. I saved all snapshots, and restarted JProbe. The initial snapshot was read correctly, but the final snapshot threw an NegativeArraySizeException.
So, now I am looking for other tools which are able to find memory leaks without hanging or crashing after running 24 hours. Any recommendations?

I dont know any other profiler you can use, but how about using the divide and conquer approach?
Disable a significant section of your application and let it run for a day. If the leak occurs, its in the non disabled part.
If it doesn't, its in the disabled part. Next, enable all the code. Then disable about half of the half that failed and try that. Continue doing so until
you isolate the code enough that you can look at it and hopefully find the problem. Note you will need to keep track of what you previously enabled and disabled as a test (I put comments in the code).
Alternately, you can look at functions that perform complex functionality that you suspect might be the problem and have the function return
dummy data rather than perform the functionality. If the leak goes away, its that function(s).
Example:
public String getComplexData(String arg1, String arg2){
//this section bypasses the complex code and returns dummy data
boolean x1= true;
if(x1==true)
return new String("some dummy data");
//complex functionality goes here.
Also of help would be to list everything that can cause a memory leak (I assume its a memory leak and not a resource leak such as not closing connections).
Here are some ideas:
1) persistant class variables that are a collection that have objects added to them but never deleted and allowed to be garbage collected
such as static class variables, session scope variables, or application scope variables.
2) An object tree where one of its nodes is never set to null to be garbage collected (such as a static class variable).
If you are running a web application in a clustered enviornment, try running it on only one server.

Agents on App-Server hosts alerts "Resident Memory Utilisation" 300Mb

I've recently upgraded our GRID installation to 11g - for both OMS and Agents.
But now I get alerts on both our Application-Server hosts complaining of high Agent resident memory utilisation (frequently higher than 300,000Kb)
The default warning & critical thresholds are set at 128000 and 256000 respectively - and the documentation seems to suggest that these could be trimmed downwards rather than upwards.
(Running on Windows Server 2003R2 (64) - with 12Gb of memory)
Is this situation necesarily bad or unusual?
Edited by: howard_d on 16-Jun-2011 08:43

Thanks Eric.
There are quite a few targets on these boxes (16 each) since there's a AS Mid-tier and Infra-tier on each one.
So, I've changed the thresholds upwards.
Thanks for the reassurance.

Sar command to find out total percentage of memory utilisation for a day.

Hi,
I am in a process of taking last 10 days average percentage of memory, CPU and Disk utilisation in solaris8.
Can any one help me regarding in this.
I found sar command and I got the details of CPU by using #sar -u -f sa23 command.
For memory If I try sar command with �r option , it gives only free memory details only.
#sar -r -f sa23
00:00:01 freemem freeswap
01:00:00 173009 14301230
Average 172860 14302592
Is there any way to find out total percentage of memory used?
And also
Total percentage of disk utilisation also in solaris8?

Average value of freemem is 172674.The average amount of free memory over the course of a day doesn't seem to be that useful. I'd want to look for the low points (see if we're close to running out during some periods).
Is this value in Megabytes?
# man sar
     -r    Report unused memory pages and disk blocks:
           freemem
                 average pages available to user processes.So it's in pages. You can use 'pagesize' to verify your page size. On modern SPARC systems, it will be 8KB.
from this value can we calculate total memory utilized for this day? like totalmem - freemem = usedmem Depending on what you mean by utilized, yes. Memory can be used for a disk cache, but that use is not shown by decreasing freemem. Uses that are counted are kernel reservations, runtime pages for applications, and direct memory allocations (malloc, etc.)

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson
Power Mac G4 Quicksilver 867 Mac OS 9.2.x 17" Studio Display, 512MB RAM

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson

Need Help finding Memory for Mac Pro

Hello,
I need to buy some memory for some of our computers and want to make sure I get the right ones. While searching I have yet to find one that actually says it is specifically compatible with our computers.
Here are the computer specs:
Model Name:          Mac Pro
Model Identifier:          MacPro1,1
Processor Name:          Dual-Core Intel Xeon
Processor Speed:          2.66 GHz
Number Of Processors:          2
Total Number Of Cores:          4
L2 Cache (per processor):          4 MB
Memory:          1 GB
Bus Speed:          1.33 GHz

I know they need to be installed in pairs so I'm looking for either a 2GB Upgrade (2x1GB) or 1GB Upgrade (2x512MB).
Thank you in advance,
Randy

Amazon has excellent top tier likely better $40 2x2GB which I and others have been buying up.

IPhoto keeps "finding" memory card

iPhoto '09 problem.
iPhoto keeps "finding" the memory card from my camera as a device (even when the card is not connected), not just once but again and again and again .... at least 10 times .... sometimes it doesn't stop and have to force iPhoto to stop. have to re-start if I want to have a chance to work with iPhoto. Very frustrating.
Any ideas on what is going wrong? how can i fix it?
Thanks in advance.

Try trash the following file
com.apple.ImageCaptureNotifications.DeviceDiscoveryDatabase.501
from HD/Library/ Caches
and restart your mac.

How to find memory taken by a process using top command

I wanted to know how to find the memory taken by a process using top command. The output of the top command is as follows as an example:

I hope, my question is clear as to how to find the memory taken by a process using top command.
Please revert with the reply to my query.
Regards

Have you tried "man top" to see the documentation for the top command?
How about the following: http://lmgtfy.com/?q=show+memory+with+top+command
The 5th column (VIRT) shows the amount of RAM + swap
The 6th column (RES) shows RAM
The 7th column (SHR) shows memory shared between processes

How to find memory used by page tables

Is there a way to find out how much memory is currently being used by page tables? I am new to Solaris ;-)
I want to quantify the advantages of Intimate Shared Memory (in the context of a large Oracle database with lots of concurrent users). I want to contrast this against Linux which does not have a method of allowing different processes to share page tables that map onto shared memory. Thus, with a large number of concurrent connections where each connection creates a new process that maps onto the Oracle shared memory, a significant amount of memory can be consumed just by the page table entries.

Yes, a very recent acquisition :-) ......I'm busy working my way through it, just taught myself about mdb today but I still can't figure how to get the amount of memory being used by page tables only. The dcmd ::memstat can give me the total amount of memory being used by the kernel but I would like some more detail than that.
On Linux you can simply look at /proc/meminfo and it contains a wealth of information. I was hoping Solaris would be similar....but isn't that always the case when doing something new? We hope it's like what we already know :-) Below is an example from Linux showing that 1860 kB have been to store page table entries.
[root@makalu ~]# cat /proc/meminfo | grep PageTables
PageTables: 1860 kB
[root@makalu ~]#
