Shown Physical Memory value of BWA in TREXADMIN

Hi,
In BWA I have four blades each with 24 GB of physical memory and 12 GB of swap space. Out of 4 blades, 2 blades are backup (This is what I can see from TREXADMIN).
In TREXADMIN -> Summary, within "Memory" section it shows 94.1 GB Phys-Available. Does anybody know where this number came from? I tried all combination of total physical memory with 2 and 4 blades but I am not getting this 94.1 GB number. Anybody?
Thanks

Thanks for replying.
Tansu,
When you say its approximate total physical memory size means it is considered for all 4 bladeds. Correct?
I checked RSDDSTATBIAUSE and DB_FALLBACK coloumn does containg zero entries as you mentioned.
I am trying to get information of BWA usage. As you know SAP recommend to have BWA usage should be within 50% to have healthy system. If I cehcekd TREXADMIN -> Summary, within "Memory its shows some kind of percentage, which I am trying understand whether it is related for all 4 blades or only 2 blades.
Thanks

Physical Memory Upgrade [SAP, Oracle parameter changes]

Hello Guru,
Good day!
I'm not sure if I'm in the correct forum, please bare with me if I'm not.
We are actually planning to increase our Production [Physical Memory] server from its current size 15360GB including [oracle, SAP & OS] to 44GB memory. Do you have any idea how can we calculate to the most needed SAP / DB parameter should be increase after we allocate the 44GB in preparation for Go-Live. Below are details of my systems [oracle version, kernel, R/3 System, OS version, SAP parameter and DB parameter.
Reason for memory upgrade: will create two client in one system with a different number of users and different plant e.g. America / Canada

I feel the best way to get the parameters which needs to be adjusted is to go for EarlyWatch Check after increasing the Physical Memory of your SAP system, as we cannot say how and which parameters needs to be checked and changed.. as there is some dependiblity also between the parameters...
All the best !

Relative size of sga_max_size and sga_target to the physical memory

Dear Experts,
I have installed oracle 10.2.0.4 on AIX 5.3 with 32 GB of physical memory.
Let us say other applications on the server consume 10 GB of physical memory.
Now how should i plan the size of SGA_TARGET and SGA_MAX_SIZE on the same.

As per Oracle® Database Performance Tuning Guide 10g Release 2 (10.2):
You must then divide the resulting memory between the SGA and the PGA.
For OLTP systems, the PGA memory typically accounts for a small fraction of the total memory available (for example, 20%), leaving 80% for the SGA.
For DSS systems running large, memory-intensive queries, PGA memory can typically use up to 70% of that total (up to 2.2 GB in this example).
Good initial values for the parameter PGA_AGGREGATE_TARGET might be:
For OLTP: PGA_AGGREGATE_TARGET = (total_mem * 80%) * 20%
For DSS: PGA_AGGREGATE_TARGET = (total_mem * 80%) * 50%
where total_mem is the total amount of physical memory available on the system.

Physical Memory: 97%

I have a SQL Server 2008 R2 on Windows Server 2008 R2, on 64-bit virtual machine, dual processors dual quad core , and 32 GB RAM.
If I restart the server, and after all the processes and services start running, the used memory is not more than 4 ~ 6 GB (I don't remember exactly, but small compared to the overall 32 GB). Every day the used memory increases for 2~3 GB!, till it reaches
97% of the physical memory (31 GB), 29 GB of them for the SQL Server:
My question is how can I know what SQL Server processes or queries causes those increases in the memory? and if it is a process or query, why the used memory is not released after that process or query finishes ?!
Honestly, there is no complain about the performance of the server, but the weird thing is that as much as I give the server RAM as much as the SQL Server takes! The server was 8 GB and I increased it to 16 then 32 GB, but the SQL Server keeps eating more
and more!

Hi,
>>If I restart the server, and after all the processes and services start running, the used memory is not more than 4 ~ 6 GB (I don't remember exactly, but small compared to the overall 32 GB). Every day the used memory increases for 2~3 GB!,
till it reaches 97%
This is the way SQL Server memory works.When you restarted it its usage was low slowly you started running complex queries on SQL server which required pages from disk now SQL server started bringing these pages from disk into memory to make sure your query
is satisfied .Now when second time you use same query it will be fast as comapared to previous attempt as now there is no use of bringing pages in memory .Now if SQL would have released memory back your time taken would have been same and you would complain
about query being slow.This is the reaosn SQL caches as much data page it can so as to satify query from meory not picking pages from disk which is costly.But if Os faces presasure and SQLOS asks SQL server to trim its memory consuption it will do it politely.So
please dont be alarmed with SQL server using memory.
PLease dont look at task manager for SQL server memory consumption it might not show you correct memory utilization .I always recommend below DMV
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
If you do not want SQL server to use much memory you can change it from sp_configure by setting lower value for max server memory.But I am in favour you shoudl not do that .Set an optimum value for max server memory leaving 7-8 G for OS and other processes
running.
>>My question is how can I know what SQL Server processes or queries causes those increases in the memory?
I have never tried that and its little difficult to find what process unless that process is runnin.There is DMV sys.dm_os_buffer_descriptor which will tell you which database is using how much memory.Below query will resturn count of page loaded by each
database
http://technet.microsoft.com/en-us/library/ms173442.aspx
SELECT COUNT(*)AS cached_pages_count
,CASE database_id
WHEN 32767 THEN 'ResourceDb'
ELSE db_name(database_id)
END AS database_name
FROM sys.dm_os_buffer_descriptors
GROUP BY db_name(database_id) ,database_id
ORDER BY cached_pages_count DESC;

Detailed memory consumption of BWA

Hi BWA experts,
My customer has faced memory compumption incresing day by day (after starting BWA 3 GB used but it increses 8,9 GB after using several days). I guess memory of BWA consists of actual index , temporary result block of query execution, exec code of BWA and so on. However there is no way to analyze memory usage , as far as I know.
Is there any way or tool ,,,etc to find out which ojects are consumed memory of each BWA blade ?
Thank you.

Hi Hiroaki,
I don´t know if I understand your question correctly. You see under Memory Info on all you host a value called "process" and you want to know which processes are behind it, or? So you want to know which query or process chain is currently active and what ressources it needs, correct?
You only can see the current load under Landscape -> Services -> Load
but directly detailed information like SM50... I don´t know where you get such information.
You can only combine your information when a process chain is running and what for a load is on BIA, but both information together on one grap I never see till now.
Best Regards,
Jens

RAC node process using 25% physical memory

We have a QA server is non-RAC, and production is two-node RAC. We have a migration app that does an INSERT from SELECT over 2 instances. All of the machines have been in successful day-to-day use for several months...our only troublespot seems to be the migration app.
Today we started the app on the QA server and watched the oracle processes using top. They ran normally and finished without any problems.
The same app started on either of the RAC nodes produced process memory errors and died.
As the app ran, there was a process reading the data from the source instance and a process writing to the target instance. We confirmed this by querying the session data. It doesn't matter which of the nodes runs which target process...the result is the same.
The reading process(session) on the source instance seems to run normally. The write process on the target instance, however, begins slowly accumulating memory in about 16M chunks and holds on to them.
We saw this in the RES and in the MEM columns of top. The target process never released any memory, but slowly grabbed it until its
RES was 4GB and the %MEM was about 30%. The app then died with process memory error. This is reproducible over several runs.
( Per Metalink Note 567506.1, the recommended value for Linux 64-bit is 4294967295 ..we have that set. )
There are other oracle processes and instances running on both nodes which do not seem to be affected. The total number of processes on each machine is around 750..much lower than the nprocs ulimit of 63K.
These process are both oracle sessions spawned by the app.
I haven't seen any info on the web or Metalink that matches these symptoms, so I thought I'd try the experts.
Why would the write session continuously use up physical memory, but only on RAC nodes?
We are running RHEL5 on Dell Poweredge 2950 w 16K Physical mem. Version of 10g is R2.0.4.

RES was 4GB and the %MEM was about 30%. How does the writer process work? Does it use PL/SQL? Does it use bulk processing? How does it call the reader process? Or does the reader process call it? Is this over a database link.
The app then died with process memory error. This is reproducible over several runs.If this is an Oracle server process, then there should be an entry in the alert log of the instance that recorded the crash and includes the name of the trace file generated by the crash.

[Urgent]How can I write to physical memory by using LabVIEW 8.2??

Hi everybody,
I am dealing with a project related to micro-EDM. We feed the gap voltage back to a NI DAQ card (not quite sure about the series number, might not be important to this problem), and we want to use this voltage to determine the command position of the motor, which is controlled by a Delta Tau PMAC motion controller. Now the problem is, the NI DAQ card and Delta Tau PMAC controller cannot communicate directly with each other. Therefore, we want the LabVIEW to write the value of voltage to a certain physical memory address, and then let the PMAC controller read that address. Is this feasible by using LabVIEW and NI-DAQ card? Which block or library in LabVIEW shall I use to achieve that? Or is there any alternative way to do it? Thanks a million!
I have to get this done by the end of this week....if you know how to do it, please let me know. I really appreciate it! You are my lifesavor!
Regards,
Xiaofei

Physical memory dump error on my A60-155

I have got a Satellite A60 and recently when just turning on the computer after a week period of not using it, it gave a 'physical memory dump' and then asked if I want to start in safe mode or last known working settings or start windows normally. None of these options worked, all the computer did was dumping its memory. So I tried the recovery disc, it loaded all the required things but yet again it did a memory dump on load up.
So I formatted the laptop and tried a newer copy of windows XP on it (Both home and Professional) doing this did work (By that I mean it installed) and windows loaded as it should, I loaded the sound drivers and all the rest of the needed drivers, restarting the computer every time I installed a new device but when it came to the 'ATI Radeon Mobility 7000 IGP' driver as soon as it restarted it dumped the memory.
As soon as the ATI driver is installed the system will not load, but the new windows I have installed does let me start on last worked settings (This removes the graphics driver) So I went onto this Toshiba website and got the driver from here seeing as ATI doesn't provide the drivers for its merchandise, and yet again it resulted in the system not loading. I need to have the graphics working because without it I cant watch films or use my CAD software I need it working.
PLEASE HELP!!

Hello
Please try to use these settings shown on this page http://www.barrett.net/xpmemorydump.html .
By the way the graphic card should be installed at the beginning. After OS installation first that should be installed is the chipset driver and than graphic card driver. After that you can continue with all other drivers.

Kernel, virtual and physical memory

Hi,
I would like to get a clarification of the uses of the terms kernel, virtual and physical memory. Functions like kmem_alloc provide non-paged 'kernel' memory, but is this a pointer to a physical memory address, or is it similar to a virtual address that gets mapped by the memory management when it is referenced like virtual memory?
Is there a way to determine a mapping between a virtual address and a physical address? (like vtophys in bsd or virt_to_phys/virt_to_bus in linux) ?
Is all memory that is normally used within a driver (e.g. messages through a STREAM or DMA areas) 'kernel' memory, and is this a direct physical memory address (as asked above)?
Many thanks
S.

Hi,
Most kernel code and device drivers will only use virtual addresses. Yes, it is right!
But I want to access a specific physical address.
Because the bus bridge chip with PCI bus-master access a specific physical address directly.
My system configuration is below:
Platform: IA32
Address map:
0x00000000 - 0x000FFFFF: Main Memory, VGA Frame Buffer, Boot ROM
0x00100000 - 0x0FFFFFFF : Main Memory(DIMM) - 255MB*
0x10000000 - 0xFEBFFFFF: PCI bus memory space
0xFEC00000 - 0xFFF7FFFF: Not Used
0xFFFF8000 - 0xFFFFFFFF: Boot ROM
*My system has 128MB DIMM on board.
The bus bridge chip access a physical address at 0x06000000.
I tested whether it would be set up correctly by using Linux as follow:
1) Memory size is specified to 96MB compulsorily.
init: Linux mem=96M
2) Access to Physical address space via virtual address in kernel space.
init_module(){
va = iormap(0x06000000, size);
*va = value;
value = *(va+n);
3) work good.
I tried on Solaris by the same way.
But I cannot find working.
1) Memory size is specified to 96MB compulsorily.
In /etc/system:
set physmem=23723 <- Page size is 4K in my system. lower than 96MB.
2) Access to Physical address space via virtual address in kernel space.
xxx_attach(){
ddi_regs_map_setup();
ddi_putX(value);
value = ddi_getX();
driver.conf
name="xxx" class="sysbus" reg=0,0x06000000, size;
And I tried access by using /dev/mem.
This also went wrong.
dose anyone have good idea?

4GB Physical Memory but 3.67GB Used

Hey there, I'm not so great with computers, I essentially know the basics, and thought might as well post a question about it and see where that takes me. I appreciate the help! Thanks in advance!
I have a 13-inch Macbook pro (Mid 2012) with 4GB memory. I was browsing around and discovered a table in the activity monitor stating the following;
- Physical Memory: 4.00GB
- Memory Used: 3.75GB
- Virtual Memory: 4.51GB
- Swap Use: 35.3 MB
From reading other questions and the responses to them I have realized that Maverick takes up a lot of memory but I'm not quite sure why my swap used isn't zero. I don't have much on this Macbook and have bought it recently. Why is the Swap use not zero? Is it a bad thing that it's 35.3MB?
The reason I was looking around was to figure out if my Macbook would be good to run downloaded games and such on; this is a shared laptop and that's what my brothers are interested in doing for the most part. Yes, we have a huge age gap.
Much appreciated,
Simran

Swap is always used. No big deal. What is a big deal is PageOuts.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
OS X Mavericks- About Activity Monitor
Memory Management in Mac OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

Physical memory inside a zone

Hi,
I have zones that have both physical and locked limits:
capped-memory:
        physical: 600M
        [locked: 512M]
rctl:
        name: zone.max-locked-memory
        value: (priv=privileged,limit=536870912,action=deny)Inside the zone I can display the locked memory with this command:
[root@zone1] $ prctl -i zone -n zone.max-locked-memory -t privileged zone1
zone: 2: zone1
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
zone.max-locked-memory
        privileged       512MB      -   deny                                 -Is there a way to find the physical property of the capped-memory from inside the zone?
Thanks.

[root@zone1] $ rcapstat -z 1 1
    id zone            nproc    vm   rss   cap    at avgat    pg avgpg
     8 zone1               -    0K    0K 200M    0K    0K    0K    0K

Primavera windows services physical memory utilization continously goes up.

Hi All,
In our primavera server, primavera services memory utilization continously goes up, even no user logged to application.
may i know, what is causing this?
Is any solution for this.

hi team,
we are having 2 node cluster setup and 3 sql server instances, those 2 nodes are active and passive.
my 3 sql server services are running on active node, here how we can find the which instance services occupied more physical memory.
go to task manager --> processes-->
here it's showing like this but it did't show the sql server instance name, how we can find the instance wise memory utilization's

Hello,
Below query will tell you SQL server utilization.And please dont refer to task manager for SQL server memory consumption.It might not always show you correct value.
http://mssqlwiki.com/sqlwiki/sql-performance/troubleshooting-sql-server-memory/
Below query only valid for SQL server 2008 and above.Run it on each instance
select physical_memory_in_use_kb/(1024) as sql_physmem_inuse_mb,
locked_page_allocations_kb/(1024) as awe_memory_mb,
total_virtual_address_space_kb/(1024) as max_vas_mb,
virtual_address_space_committed_kb/(1024) as sql_committed_mb,
memory_utilization_percentage as working_set_percentage,
virtual_address_space_available_kb/(1024) as vas_available_mb,
process_physical_memory_low as is_there_external_pressure,
process_virtual_memory_low as is_there_vas_pressure
from sys.dm_os_process_memory
go
Also some memory are allocated directly by windows which might not come from buffer pool can also increase memory consumption

Physical memory and paging

I know in SAP's world, memory means physical memory + paging. I want to know which program has contribution for swap.
Suppose there is 4G physical memory on an application server, em/initial_size_MB = 4G, abap/heap_area_nondia = 4G.
1) If there is no dialog processor running and one background job running which claims 2G memory, I want to know will swap occur?
2) If there is one dialog processor running which claims 2G memory and one background job running which claims 2G memory, will swap occur?

By ST03N you can check the workload, by OS06 the swap .
By transaction ST02 you can check the folllowing parameters:
SAP Roll area parameters
- ztta/roll_first          : First amount of roll area used in a dialog WP
- ztta/roll_area             : size of the local SAP Roll area in the work process
rdisp/ROLL_SHM      : size of SAP roll Buffer
rdisp/ROLL_MAXFS     : size of entire shared SAP roll area
SAP Extended Memory main parameters :
em/initial_size_MB : size of SAP extended memory allocated when                         the SAP instance starts up
em/blocksize_KB : size block which split SAP Extended Memory
ztta/roll_extension : maximum size of a user context in the SAP Extended memory
SAP Heap Memory main parameters :
abap/heap_area_dia       : quotas oh SAP heap memory that a dialog                                 process can allocated.
abap/heap_area_nondia : quotas oh SAP heap memory that a nondialog                    process can allocated.
abap/heap_area_total     : size that can be allocated in total by all work                    process.
abap/heaplimit           : Workprocess restart limit of heap memory
if helpful reward point is appreciated
