Enquiry Regarding Memory Allocation

Hello.
I tranfered a mp3 file to Gallery - Music Files.
The Free memory of the telephone fall down from 7.2 to 4.5 MB. But the Gallery memory raised from 4.2 to 7.3 MB.
This means that my telephone memory for contacts, calendar and so on is less than before transfering the music, right?
Howcome this is possible? My Gallery memory should fall down a bit instead raising.
How this memory thing works? What is the difference or advantages of free telephone or Gallery memory?
Thank you.

memory will be allocated for Objects or class?Ram will be allocated for the object. The object is essentially a copy of the class.
In simple terms,
Class = factory,
Object = products from the factory
So, yes memory will be allocated to store the object in RAM. Suppose you make 5 new Dog objects from a Dog class. All these objects will be in RAM. They all have a different addresses.
Hope that answers your question.

Regarding memory allocation & deallocation of memory during portal access.

Dear Experts,
Please help me with the below simple query.
I am working on webydnpro abap for develpment. Lets suppose, If i have 2 links/applications in sap portal , both are individual sap webdynpro components. If i click 1st link/application in portal, then it will call the url of web dynpro abap component. If i click 2nd link immediately after 1st link, then it navigates and opens the 2nd application. But the memory is still open for 1st application as well as 2nd application. So the load is getting increased though the user may acess the application or not .
So could anyone suggest on what should be done, for terminating the memory allocation of 1st application while accessing 2nd application and vice versa.
Regards,
Murali.

I can't offer much in the way of details, but you might want to investigate USBTMC (USB Test and Measurement Class). With a driver written to this spec, you use VISA commands to the USB instrument in exactly the same manner as a GPIB device (i.e. VISA Write "*IDN?", VISA Read "response"). Drivers that implement this are much easier to use than exposing USB Raw. This will take more work on your end but will end up with greater customer satisfaction. This is the route we're taking with some instruments developed for internal use. They may never be commercially released but the current customer (me), is very happy. The developer started by googling USBTMC and went on from there.

Regarding memory specifications

Hi,
I have some doubts regarding memory allocations...
1. On what ratio should I allocate SGA & PGA size based on RAM size...(For Ex: my RAM size is 8GB)
2. Which value should I set for sessions & open_cursors for database (Will it depend on number of users accessing database?)
Thanks in advance....

2. Which value should I set for sessions & open_cursors for database (Will it depend on number of users accessing database?)
Thanks in advance....It is also depend your application and how much concurrent session will/need.

Memory Fragmentation Problem or Bug
This situation means that a process has consumed a large amount of processor memory and then released most or all of it, leaving fragments of memory still allocated either by this process, or by other processes that allocated memory during the problem. If the same event occurs several times, the memory may fragment into very small blocks, to the point where all processes requiring a larger block of memory cannot get the amount of memory that they need. This may affect router operation to the extent that you cannot connect to the router and get a prompt if the memory is badly fragmented.
This problem is characterized by a low value in the "Largest" column (under 20,000 bytes) of the show memory command, but a sufficient value in the "Freed" column (1MB or more), or some other wide disparity between the two columns. This may happen when the router gets very low on memory, since there is no defragmentation routine in the IOS.
If you suspect memory fragmentation, shut down some interfaces. This may free the fragmented blocks. If this works, the memory is behaving normally, and all you have to do is add more memory. If shutting down interfaces doesn't help, it may be a bug. The best course of action is to contact your Cisco support representative with the information you have collected.

Internal Table Memory Allocation

Hello all,
I could understand the difference between Internal Table with occurs 0 and internal table with type declaration...
correct me if i am wrong, occurs 0 declaration occupies 8kb memory and header line 256 bytes...
But what i could not get is...
Where can i view this internal table runtime memory usage?? Should i have to check that in some transaction???
If that is the case, what transaction i should look at?? Can i view this in debugging mode??? I tried GOTO -> STATUS DISPLAY -> MEMORY USE and i have tried even SETTINGS -> MEMORY MONITORING ->MEMORY DISPLAY ON...Nothing worked..
when i go for GOTO -> STATUS DISPLAY -> MEMORY USE in debugging
memory allocated seems to be same for Internal table with occur 0 and Internal table with type declaration
I have searched a lot about this in SDN....But could not come to a conclusion......
I don't have authorisation here for DBG_MEMORY_DIFFTOOL or S_MEMORY_INSPECTOR unfortunately.....
Waiting for your replies....

Hi Jagannathan,
You can view this on Debugger(ECC6.0) onwards.
To find out how much memory internal tables occupy, choose Goto --> Display Condition --> Memory Usage.
Choose Change Settings to display a window, in which you can choose the Internal Tables button.
Hope this will assists you for your quest.

Dynamic memory allocation failure

Dear reader,
We sometimes have a problem where our windows 2012 r2 RDS virtual servers, that reside on windows 2012r2 hyper-v hosts, loose their dynamic memory and only have their startup memory left to work with. Users start complaining that things are very slow etc.
If I check several screens (RDS Broker load balancing, hyper-v manager, cluster manager and the vm's task manager) it's clear that the vm only has its startup memory allocated. I'm not sure if this happens instantly or immidiatly after the nightly reboot.
To resolve the problem we have to call all users on the vm where it happens and ask them to logoff (if they are even able to), and then we reboot the machine.
I have checked the logs from the machine where the VM resides on and the logs from the vm itself. But I cannot find anything. We also have alot of windows 2008r2 vm's with dynamivc memory, but none of those have ever had this problem.
Searched the internet, but so far it seems we are only.
Can anyone give me a lead to troubleshoot this?
Best regards,
Ruud Boersma
MCITP Enterprise administrator

Hi all,
I'm going to be "one of those people" who revives dead posts for something that is relevant but obviously not fixed... sorry in advance!
We have the exact same situation, a bunch of RDSH guests with Dynamic memory turned on (60+ of them). every day between 1-8 of them will fail to allocate Dynamic memory and will be stuck on their startup RAM amount. This really hurts our users at peak
times.
I have engaged our TAM and have raised a case with PSS, Usual story "your the only one with this problem". Which obviously isn't true.
So, we have tons of free RAM on the hosts, 600GB+ on most of them, the issue affects RDSH hosts at random, across multiple hosts and clusters.
The screen shots attached are of one of our hosts from this morning. it has 8GB startup, 8GB minimum, 32GB Maximum RAM configured, with a 23% buffer. the host has 752GB RAM FREE. Notice how the perf counter "Hyper-V Dynamic Memory Integration Service"
is reporting "0", it should be reporting "32768". also under task manager on the VM we are missing "Maximum memory" which should be just below "Hardware reserved" in the bottom right hand corner.
Looks like the balloon driver is being delayed at boot time, we are going to XPerf all the servers in the hope that we can catch the critter. It's an unusual problem.
We only have Acrobat PDF viewer, word viewer, excel viewer and two custom dot.NET applications installed on the guests. Some of the servers are also just dumb RDSH hosts, with not connection broker configured, using an F5 loadbalancer for load distribution
and session management. All guests are 2012R2 patched up to March 2015, integration Services are installed and up to date (its an enlightened OS remember).

Problem in dynamic memory allocation

Hi,
My name is Ravi Kumar. I'm working on a project to improve organizational performance which include visual studio for simulation. I'm using dynamic memory allocation to allocate space for the array that are used in the program. Now I have run-time error

Dynamic memory allocation

Hi, guys, does anyone know whether I can use dyanmic memory allocation on the Real time system with "call library function" node. DLL is programmed using C language. Thanks.
Machman

You certainly can. LabVIEW Real-Time functionality is really not much different than what you can do on Windows. The only difference being that you can now assign priorty and timing to your execution loops; essentially, you have determinism with RT whereas with Windows, you never have a guarantee.
Thus, in regards to calling a dll, you can perform this the same way you would in LabVIEW for Windows. Here's a KnowledgeBase article on how to do this if you're not already familiar.

Dynamic memory allocation on HP-UX for multiple instances on one host

Hi everyone,
I was wondering what the current possibilities are nowadays on running multiple SAP instances on one very large host with regard to resource sharing. Normally, for each instance, using PHYS_MEMSIZE etc you have to set the memory to a fixed size and then optimize it.
Preferrably we would like the memory to be allocated based upon actual usage. Is that possible at all? on HP-UX? Using third party techniques?
Thank you
Marcel Rabe

Hello Marcel,
As Juan said you may not be able to change the parameters at runtime.
The only parameters that can be dynamically switched are :
ztta/roll_first
ztta/roll_extension
ztta/roll_area
abap/heap_area_dia
abap/heap_area_nondia
abap/heap_area_total
em/stat_log_size_MB
em/stat_log_timeout
These parameters would put a cap on memory allocations, however they wouldn't help increase the total addressable memory area.
I would suggest that you consider Adaptive Computing for dynamic use of resources.

Memory Allocation to JVM

Hi
How do I allocate Contiguous memory space to JVM 1.3 in Windows and AIX?
Regards
Sudhindra

Hi
You are right. But the issues here is performance
enhancement. I feel that when we are talking about
huge volumes of data and transaction performance will
be enhanced if the memory allocated is contigous.
As far as I know all modern platforms use virtual addressing. The overhead of that applies regardless of layout of physical memory. So I am not sure how contiguous blocks would help.
So can you please tell me how to do this? Where can i
get more information about this?
Like I said maybe it is specific to your platform. If so you need to look to the docs about your platform. And the only way you are going to get any advantage from java objects from that is if you write your own jvm.

Memory Allocation

I have Premiere Elements 2 and Windows XP SP3. We have 1GB of RAM and 500 GB Hard drive with only 50% used. I save my videos on an external hard drive.
I have always satifactorily burnt my DVDs with the system as it is, including a short DVD last week. In the last couple of days I've been trying to burn my DVd but Adobe fails part through the burning process as it is running short of memory allocation. We have followed previous instructions on the forum and turned off background applications. Can anyone help? I burnt something much longer without a problem about 3 weeks ago and am a loss as to what to do.
Thanks Erika

Thanks. I don't use any stills in my DVD, just music which I import in the way I have always done and it's been ok. For information my audio clips are either MP3 Audio or Windows Media and files are up to 4.3MB. These are ripped from CD via Real Player (Windows Media seems to encode them and I cannot download to Adobe via WM)
Source: 44100HZ 16 bit and Data rate approx 23.4375 KB.
SHould I be doing anything else?
Any further suggestions would be appreciated.

Memory Allocation Error during Boot

Hi,
I am posting this on a different computer than the one on which I istalled Java because I can no longer get it to boot.
Here's the history:
I am working in Windows 98
I added a line to the autoexec.bat so that the PATH lines looked like this:
SET PATH=C:PROGRA~1\UTILIT~1\SYMATEC\PCANYW~1
PATH=%PATH%;"C:Program Files\Mts";"C:j2sdk1.4.0_02\bin
I then rebooted and tried the javac and java commands in different folders and everything worked fine. I shut down the computer and tried to reboot a day later. The following are pieces of the message I received (I don't usually go near the autoexec.bat or system settings so I have no idea how to get past these errors, nor fix them):

You should try a forum/newsgroup for Windows for more help. My own suggestion would be to load to the command prompt (or try safe mode). (Press F8 during boot to get a menu.) And then run scandisk manually. If it works, try renaming the C:\WINDOWS\SCANDISK.ALT file and rebooting.

Memory allocation model on Windows

We have an application server with 16 GB of RAM and 54 GB of SWAP.
The application server run on a Windows 2003 IA64 SP2.
We are using 6.40_ex2 kernel.
When we run intensive memory program (program that use a lot of memory in internal table) we see that all the EM is allocated in PM.
HM too is allocated in PM until the PM rech less than 200 MB.
When the PM is less than 200 MB the total VM used on the server is less than 25 GB (EM: 10 GB; HM < 10 GB).
There are SAP kernel rules that defined what allocate in RAM and what allocate in Paging file?
We think that should be a better distribution from RAM and SWAP but we don't know if it is a right consideration.

Essbase should use the amount of memory allocated in the Database settings, (plus some overhead for the Agent / App Server itself, which should be nowhere near 4G).Take a look at the database settings within the application. Look at the Index Cache, Data Cache and Data File Cache to ensure are not set absurdly high. As a test, leave them at their default values - worry about tuning them later.Also, how many Essbase applications are running on this server? Is it just the one?Regards,Jade-----------------------------------Jade ColeSenior Business Intelligence ConsultantClarity [email protected]

Memory allocation error when burning in premiere elements 2

I have premiere elements 2. I happily burnt a version of my dvd then suddenly it stopped burning and I had the above message during the burning section of the process. My computer has adequate memory to run this programme and nothing new has been added. I then downloaded Premiere elements 7 as a trial and burnt this Dvd yesterday. However today it won't burn through 7 either so i am reluctant to upgrade unnecessarily. Can anyone shed light on why I receive this error message.
Other things seem to burn but I am beginning to receive messages that Adobe is low generally on memory allocation.
