About extend memory used in ST02

Dear expert
Is there a way to know how extend memory is used in ST02
When system start,no user log on we can see:
SAP Memory      Curr.Use % CurUse[KB] MaxUse[KB]
Extended memory     1.95 122，880 208,800
But we can find ,after user log on,the extend memory wiill increased.
SAP Memory      Curr.Use % CurUse[KB] MaxUse[KB]
Extended memory     54.92 3,452,928 3,768,320
I checked sm04 and stad,no such large amout of memory used.
We can see the problem in Y55.
Is there any way to know how the extend memory is used?
Thank you very much for your help.

The value specifies the size of the roll area in bytes.The roll area is one of several memory areas from which the memory
requirements of user programs are satisfied.For technical reasons, approximately the first 250 KB of a user context is always
stored in the roll area, additional data
1) to the limit ztta/roll_first in the roll area, then
2) in extended memory, to the limit ztta/roll_extension    or, if extended memory is exhausted, then
3) in the roll area again, until the roll area is full, then
4) in the heap memory (PRIV mode), to the limit    abap/heap_area_dia or abap/heap_area_total or until    the address space or
the swap space is exhausted.
Tthe case of non-dialog work processes, the sequence 1) 3) 4) 2) applies. After this, terminations occur, with errors such as:
STORAGE_PARAMETERS_WRONG_SET or an error code that indicates a memory bottleneck.

648 max , testing base and extended memory

I dont see the thread i answered to one time that someone spoke of using ddr400 with 648 max or max-L board and they were getting testing base and extended memory error from the LED's. Well i just got the same error today and my system would not boot i cut the power to the PS. and turned it back on it would start to boot and hang i could barely get to the windows logo sometimes the vid card wouldnt even boot the logo to the screen. This is with an updated mobo that msi sent me that i had just put in , it seemed to run fine at first then this problem started occuring. The only difference i had in the setup from the previous outdated board was i had the mem in DIMM 3 and not DIMM 1, so i moved the memory back over to DIMM 3 and now the problem is gone. Just something for those of you with the same problem to try.
Oh and i forgot one more issue, i cannot set the dram speed in the bios manually i have ddr 333 it should be 167 mhz so i set it to 4/5 and the system will not boot at all i end up having to reset cmos. I called MSI about that and they told me to just have it set to SPD , I said i know that and im fine with leaving it that way but it should let me set it manually if i wanted to and that i wondered if that had anything to do with the random " testing base and extended memory " problem.

It was probably myt thread...
http://www.msi.com.tw/program/e_service/forum/viewindex.php?threadid=6204&boardid=10&styleid=1
Have done some testing with both DDR333 and DDR400 and my results are in the thread.
Right no I'm using my DDR400 as DDR333, manually set to 167MHz, using DIMM1, and havn't seen any problems. I'll try the DIMM3 to see if I get any changes.
And by the way.. I tried setting my DDR400 manually to 200MHz and it wouldn't boot at all. After a lot of ugly language I finally got it back to the BIOS....after a reset of the CMOS.
Seams like you should use SPD if you want to use the correct freq for your RAM.
Have you tested the new 1.3 BIOS?

K8N Neo2 boot problems, freezes at testing base and extended memory

I recently bought a motherboard/cpu combo and been having problems. I'll start with my system specs:
MSI K8N Neo 2
AMD 64 3000+ Rev E
XFX Geforce 6600GT
Corsair Valueselect 184-Pin DDR SDRAM Unbuffered DDR 400 , 4 512MB sticks
400W Powersupply
I ordered a mother/cpu combo along with other parts to build a new computer. Finally everything arrived a couple days ago and I started building. First I installed the mb, cpu, ram and vid card to make sure everything was working. When I started it up I got nothing. So I started messing around and dropped the ram down to only one stick and used the D-Bracket. I figured out the cpu had been dislodged during shipping, got it installed again and was able to boot up could get into the bios etc. I put back in my other three sticks of ram everything seems to be working. Next I hooked up the hd, cd/dvd etc. Tried to boot up and it freezes after listing the total memory. Looking at the D-Bracket it shows it freezes at Testing Base and Extended Memory. So I unplug everything back down to just cpu, ram and vid card to see if it still works. It freezes again at testing base and extended memory.
At this point I drop the ram back down to one stick. It boots up and I can get into the bios again. So I shut everything off and put back in the rest of the ram. Turn it on and it freezes at the same point. Hmm, drop it back down to one stick and I can make it through to the bios. Now I'm just frustrated and want to see if I can get my other components working and maybe windows installed then I'll come back to figuring this out. So I save and exit the bios, while it's rebooting again it freezes at the Testing base and extended memory.
After playing around with it some more over the past day here is what I've come to see. If I move one stick of ram around I can get past the testing extended memory to get into the bios or up to the point of needing a boot disk etc. If I reset or reboot it from this point it will freeze. If I just leave my computer alone and off for around 30 minutes I can start it up once then it will freeze. Now I'm just confused why it will intially start up as everything is ok but freeze if it resets. Everytime it freezes it will be at the Testing Base and Extended Memory.
Some things I have tried while talking to a friend about the problem is clearing the cmos and also putting in the ram settings in the bios. Neither seems to work. I've done a lot of searching on google and in this forum and haven't seen anyone talk about a problem like this so hopefully I'm not missing anything.
If there's anything else you guys need to know about my setup let me know. I also hope I wrote this all clearly because at this point I'm pretty frustrated.
Thanks!

Ok, newest update.
After clearing the cmos I put in a stick of ram. Everything loaded up ok and I went into the bios and entered the values (2.5-3-3-8) and 2.75V. To my amazement it didnt' lock up after saving and exiting and it made it through to the Disk Boot Failure etc. So I hit the reset button to see if it would go all the way through again and it froze again with D-Bracket LEDs showing the Testing base and extended. I turned off the case with the on off switch in the back and powered up again. It went right through in the past I'd have to wait. So it seemed like things were a little better.
So I put in a second stick of ram and it booted all the way through, tried to reset to see what would happen and it froze. Turned power on and off and it froze not making it anywhere. Tried that a few more times and it would always freeze right away making no progress.
Back down to one stick of ram and it works again where I can go into the bios, save and exit and it'll make it through a full boot up to Disk Boot Failure. Weird thing was once after just hitting the reset button it actually made it all the way through. So it seems to act differently almost everytime.
To me at least there doesn't seem to be a logical way I can think of what the problem could be.

Extended memory is virtual memory space or Real Memory ?

HI ,
I would like to know whether the extended memory is virtual memory or its real memory. What is the parameter used to set the usage of the real memory of the system and the virtual memory of the system ( I want to know with ref to UNIX environment), and also clear about the hep memory( virtual or real).
Thanks in Advance
Rajesh Babu

Hi, I hope this will help:
The virtual memory consist of physical memory and OS swap space. Virtual memory can be allocated by the SAP system.
In the virtual memory exist shared memory and local memory.
Your question was regarding extended memory. Extended memory (user context) exist in shared memory. Heap memory exist in local memory.
Check this for more information on this topic:

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. (continued)

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. The only way I have to fix it is to change some kind of compability settings or try and access it in a new way, and every time it crashes/closed/computer blue screens that setting will no longer work.
That is a short term solution, but eventually I'll run out of ways to access firefox successfully. I've tried many solutions, and some worked, but only once. I have yet to find a permanent solution for this problem.

First please update your plugins to make sure you are up to date. Shockwave Flash player has a newer version 16. In order to better manage the memory that Firefox uses please see these troubleshooting steps: [https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram Firefox Uses too much RAM]
You also mentioned that Firefox crashes, we're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

Extended memory 50% free,but work process reach PRIV

hi,
many dialog work process reach PRIV mode though extended memory is 50% free.
profile parameters as below :
ztta/roll_first     1 MB
ztta/roll_extension     2GB
ztta/roll_area     6MB
abap/heap_area_dia     2GB
can anyone throw light ?

Hi Krishna,
In addition to the parameter you have mentioned check these parameter as well in the system.
A process going into PRIV means that either it has exhausted its quota of extended memory (ztta/roll_extension) or that the total extended memory (em/initial_size_MB) has been used up by other sessions.So increase these 2 parameter to start with and then tune others.
rdisp/ROLL_SHM                32768       8 kB Part of roll file in shared memory
rdisp/PG_SHM                  16384       8 kB Part of paging file in shared memory
rdisp/PG_LOCAL                150         8 kB Paging buffer per workprocess
em/initial_size_MB            61440       MB    Initial size of extended memory
em/blocksize_KB               4096        kB    Size of one extended memory block
em/address_space_MB           4096        MB    Address space reserved for ext. mem. (NT only)
ztta/roll_extension           2000000000 Byte Max. extended mem. per session (external mode)
abap/heap_area_total          64424500000 Byte Max. usable heap memory
abap/heaplimit                40000000    Byte Workprocess restart limit of heap memory
Also,consider setting rdisp/wppriv_max_no and rdisp/max_priv_time,so that system performance is not much impacted.

Is heap memory is particular for a workprocess?and extended memory too?

Is heap memory is particular for a workprocess?and extended memory too?
All the while I need to know is :is more than one workprocess can be in Priv mode?

Yes - heap is workprocess exclusive memory.
Extended memory is shared on the instance.
Yes - more than one WP can go to PRIV mode.

Question about extend calendar using scal? help,help

recently, we received a mail from sap which saying about extending calendar using scal;
I have read sap notes:1529649 , 501670
and my steps will be:
1> in our qas system using scal
change holiday calendar: choose CN China holiday calendar to change and then enter validation from 1995 to 2098(for example)
2> change factory calendar: choose CN China factory calendar to change and then enter validation from 1995 to 2098(for example)
3> in scal , choose menu: extras-->update calendar buffer
4> transport this change to our prd system.
5> go to scal in prd system to check
6> update prd system `s calendar buffer in scal
I do know whether my steps is right?
I have two questions:
1> we are a chinese compary, and we use several languages:TRADITIONAL CHINESE , SIMPLIFIED CHINESE and ENGLISH;
whether i should change other holiday calendar,such as british calendar?
2> Is there something wrong about my steps?
thanks a lot.

Hi,
You are correct, But You can change it on QAS due to client will not modifiable.
Goto Developement System and run scal.
Most important is to change/extend factory calander and save it. Request will be generated as Workbench. Transport it to Production System.

Question about sap memory

May I ask that how long did you restart your sap system? Because in our sap system, the memory usage is always rising,     in the beginning of sap starting, the computation memory usage is 60%, after several days, it becomes 90%, and then uses paging space,,   some memory used by sap work processes will not release automatically.
It is necessary to restart sap system after several weeks?     Could you give me some advices?

Hi, can you check the t-code st02 are many swaps after long time running ?
Check and post here the
St02 --> detail analysis meny --> Storage. you can see the Virtual memory allocated "Total", how mutch it and User storage for all work processes, Storage Shared Between Work Processes --> total allocated.
Per your configuration looks --> 3 GB are SGA_MAX_SIZE ? or it not seted up ?(in any case db_cache:2GB + shared_pool:1GB = 3GB) the extended memory are em/initial_size_MB = 4096 , also for sap buffers are set some memry,for OS itself, the Heap are also 2Gb, as you can see 8 GB are not enogth and you will see
swap's. Are this greatly affects the performance?
I'm not work with AIX, mey be it some specific AIX problem's to try to read:
Note 973227 - AIX Virtual Memory Management: Tuning Recommendations
Note 78498 - High paging rate on AIX servers, in particular DB servers

Now SAP Expert recommand us extend memory em/initial_size_MB to 20GB, then
how much the memory configuration in OS level has to be enlarged before change extended memory in application level ?
Thank you,

Extended memory, lack of

I have just upgrade my system, KT4 ultra 6590 BSR mobo,Athlon xp2400 and when I boot, the ram counter always shows 4096KB. I have tried it with 256 meg, 512 meg and up to 3 multiples of each, all of which work in my old computer. Same mobo. After thoe boot screen, the next screen says "windows NT requires at least 7 meg extended memory to run and you do not have sufficient" Something seems to be limiting the memory to 4096 KB. Any ideas.

Hi,
It looks like your board is damaged.
You better replace it.

I not buying the memory from crucial, but I buying in canadacomputers.ca
I need to find which ram is compatible within 7 days or else I can't refund.
pls help

crucial was the best memory back in the SDram days but in DDR i would say mushkin is the best check the sticky post at the top of this forum compatiable ram that is if your using a K7N2 board
