Using Memory

In recent days I have noticed (using a Widget called iStat Nano) that the amount of Memory being used at all times is always very high. I have 512MB of RAM, and at times it says that 490MB (+ or - a few) are being used. This seems very high, as I am only surfing around Safari, and talking to people on iChat. When I first turn the computer on, the memory used is around 300MB. I was just wondering if these numbers are much higher than normal?
Oh, and as far as breaking down what the memory is being taken up by; there is 74-76MB of Wired memory, 210MB of active, 175MB of inactive, 49MB free, and a swap of 256MB.

Essentially only half of your RAM is actively being used. KB 107918, Mac OS X: Reading system memory usage in Activity Monitor tells you how to interpret the memory information.

Reducing app size and using memory

Building with release preference Blank App template will give you a ~200kb .exe, which in running state use ~7mb of memory.
It has a huge list of external dependencies.
So, is it possible to reduce app size and using memory?
Or, how safely unlink from app headers that really didnt used?

generally speaking premature optimization is not a good idea.
Normally those tricks we learned from stone age are picked by tools already.
(http://stackoverflow.com/questions/6215782/do-unused-functions-get-optimized-out)
So if you experice performance/optimization issue
optimization ususally goes with repeated measure -> optimize -> verify
cycles.

Sql server is using memory more then there max memory setting?

Hi All,
today i have faced the different issue..........
we have one SQl server 2008 prod server... it have memory issue actually total server memory is 8GB and we have allocated the 6 GB to SQL server,we checked the server no open trans and dont have running jobs also,one database is using the memory high(no
open trans)... but Sql server has used 6.5 GB (6 GB) and total server used memory is reached to 7.89 GB.
Please tell me how to find the most costly query in particular database wise and sql server internally behavior ?
how to troubleshot the above issue?
please post the your valuable answers ASAP...
Thanks,
RAM

Please refer to what Olaf said briefly.Buffer pool in SQL server only caters to memory requests which requires pages <8 KB . Almost all requests are satisfies by buffer pool and generally request for memory is small and so buffer pool satisfies the requests.
However there are some direct memory allocation by windows API which is done by windows for requests which requires memory greater than 8 KB. This memory wont come from buffer pool and this would be counted in memory utilized by SQL server. SQL
CLR,XML, linked Server, all takes memory outside buffer pool in SQL Server 2008. This behavior changed in 2012 so my statement only applies to SQL server 2005/2008 and 2008 R2.
I would run below to check SQL server memory utilization.
select
(physical_memory_in_use_kb/1024)Memory_usedby_Sqlserver_MB,
(locked_page_allocations_kb/1024 )Locked_pages_used_Sqlserver_MB,
(total_virtual_address_space_kb/1024 )Total_VAS_in_MB,
process_physical_memory_low,
process_virtual_memory_low
from sys. dm_os_process_memory
I am sure you must be using some features mentioned above.You were worried that even though there is no query running on SQL server it has still holded up the memory. This is default behavior and this is how memory management in SQL Server works. It will
not release memory untill SQLOS asks it to do so which is told by windows OS thorugh some flag that it is facing memory pressure.
Please read below for more details on memory. There is section to test whether system is facing memory crunch please read that as well.

"Nobody" using memory?

I find the following in my Activity Monitor:
101 usbmuxd nobody 0.00 2 532.00 KB 26.98 MB Intel
Who is nobody?

A google search has produced an answer to my question of what does usbmuxd do? It's the program that looks for your iPhone in order to sync it up.
http://www.ehmac.ca/anything-mac/53805-anyone-know-what-usbmuxd.html also has links to further information if you're curious.
The second post on this thread has some great info about who is nobody. Also your concern about it using memory is likely of no importance, first because it's a really small amount, and second because in the event your computer needs that half-meg desperately, I would hypothesize that it could easily be paged out to disk and freed up until you plug that thar iPhone back in. Don't quote me on that though. Who knows, maybe it's wired down.

How to check actual allocated and used memory for java process in solaris?

Hi,
I'm testing performance for java application on solaris 10. And I would like to know how to measure actual memory allocated and used for java process.
I'm setting -Xms512m -Xmx512m for my java process and I use prstat command to monitor it's memory. But I found that when I run prstat to check, in SIZE column is more than I setting (found 644).
So I'm don't know the actual memory that java process used. (In this case,is it mean the process use memory (644) more than setting (512)?)
Thank you.

With Xms/Xmx you specify the Java heap size. On top of that comes the permanent generation (default max size 64m) and the C part of the process (the JVM itself with all its libraries and data).
With "ps -e -o pid,vsz,rss,args" you get the virtual and set resident size of your processes.

How to use memory analyser in CE 7.1 portal

Hi,
I want to use Memory Analyser in my landscape, i have installaed CE7.1 on oracle DB( remote DB) on my VM.I have downloaded the memory analyzer from the eclipse site and i have the memory analyser.exe file with me. How can i use this one to use in my server case. Currently i have installaed SAP JVM_5, and how can i get the heap dump from my SAP JVM and how can i import those hepa dumps in to my memory analyzer on the virtual machine.
Regards,
Pradeep J

Hi,
there are varios ways to get a heap dump. Have a look at this page:
http://wiki.sdn.sap.com/wiki/pages/viewpage.action?pageId=33456
If you want to trigger a heap dump on your own, ust the jvmmon tool from the SAP JVM.
Then you need to copy the heap dump to a place where Memory Analyzer can open it. In Memory Analyzer just ust the File -> Open Heap Dump menu.
Does this help?

Krum

Do you still use memory Freeing apps?

Do you still use memory freeing apps now that you have an Iphone 4?
Are there any benefits to using one, while using an Iphone 4?
I used to use these apps all of the time when I had a Iphone 3g, but I haven't found the need for one on my Iphone 4.
Message was edited by: Iskor12

I'm using the app called "System Activity Monitor" I think it costs you money to buy one, but it's a nice feature, it frees up some memory automatically if you launch the app, it also shows you what processor you are running. I barely go on it but sometimes when I check I find that I only have 5 MB of ram left and it's nice that it frees it up automatically. Other than that I don't usually check it often but there are times when I do need to check it.

I don't know. I've never tried.
Look at the manual (7210midpSimGuide.pdf in the docs directory). Maybe there is something in there. In the command line options there are a bunch of tracing options that you can specify, like tracing allocations, garbage collections, stackmaps, etc.

Why is Uncategorized Used Memory keeps increasing???

Hello, I'm making an Android game with Flash pro cc. And now I'm testing performance using the Scout. So I ran my game with Flash Pro cc's Control - Test Movie - Air Debug Launcher. And I played about 5 levels of my game, but the number of "Uncategorized" under Used Memory keeps increasing. Others such as Action Script Objects, Bitmap, ByteArrays under Used Memory decreases over time which I think it means it's garbage collecting. Is it normal to have Uncategorized keep increasing??? If no, how can I fix it so that it decreases??

http://www.adobe.com/devnet/scout/articles/scout-memory-profiling.html
From the link:
Uncategorized – other memory that Flash Player is using, but doesn't yet track. This includes sound and video buffers, XML data, and memory used by Stage3D, as well as numerous small data structures that are used internally by Flash Player. We plan to add additional categories in future versions of Scout.
In my experience, it's inconsistent and can at times consume a lot, while other times not so much. It's a nuiscance category for sure. Don't count on being able to reduce it will a silver bullet.

'Use Memory Analysis' of WebiProcessing in HP-IA64

Hi. I have a question about 'Use Memory Analysis' option of WebiProcessingServer.
According to Administrator's Guide, this option prevents memory curruption when BOE works as 32-bit application.
(maxmum memory setting is limited to 2000MB)
Then in my thinking, it's useless when BOE works as 64-bit application in HP-IA64.
So it's better that turn off that check box. Is this right ?
There is no detail description about what happened when this option turned off.

Hi
Yes, as you are running a 64-bit software on 64-bit OS, your webi processes will be able to consume > 2GB RAM.
you will need to disable memory analysis which limits you upto 2GB. While disabling memory analysis will allow Webi processes to run for > 2GB memory, there will be no control wherein the process could run away after 4 GB or whereever it hits a limit and crash. Memory analysis is a good setting as it prevents webi processes from crashing.
Lastly, you must always try to design reports and processes which dont push processes to run away using such large memory footprint.

MP 530 printer - the in use/ memory is blinking

I have lost my manuel and don't know what to do with the blinking in use/memory light. It is like it is frozen and won't print from my computer What do I do?

Hello hrjohnson.
The In Use/Memory light may come on in a few different situations.
First, check to make sure that the phone cords are connected properly. The phone cord that is coming from the phone line on your wall should be connected to the 'L' jack of the printer rather than the 'Phone' jack. Also, the cord from the 'Phone' jack would go to a standard telephone or answering machine.
If the phone cords are connected properly, it may be possible that one of the phones in the home or building are off the hook or in use.
This may also occur if a fax is stored in memory. You can print any faxes from the memory from the Menu.
In rare cases, this may occur if a USB cable happens to be connected into one of the phone jacks on the printer rather than the USB port as well.
