• Change the memory allocated for the graphics?

  Hi, I have an Equium A60-181 with graphics ATi Mobility Radeon 7000. For the moment, that this GPU is using 64 MB of my system RAM that result with only 448 MB of RAM (512-64) for Windows. For a video resolution of 1024 x 768 32 bit it's a ridiculous amount of memory since it only really requires 4 MB for this. I'm not interested in games or 3d graphics, so my question is if I can change the memory allocated to recover more memory system?

  see you soon,

  Richard S.

  HI Richard,

  ATi drivers include an improved graphics option devices-> display manager that allows the value of the AMU to change. My SA30 supports load 16 MB, 32 MB, 64 MB and 128 MB.

  The same value UMA adjustable in BIOS Setup Panel.

• Change THE Memory Allocation 6.0.

  I own a 7 '' netbook Sylvania, with 128 MB of RAM and Windows CE 6.0 OS. There the cursor to change the memory allocation between the PROGRAM and the STORAGE, but it won't budge. To get YouTube running on this thing, I need to go 68 MB of RAM allocated to executing programs for about 130 MB, taking storage (use an SD card to make up the difference - easy). Is there a way to unlock the slide or modify the default setting through the registry hive files? I have already made some adjustments with explore in this way and have managed to add a file to it. I understand in hex. Thank you!

  Hello GusCD6,

  The best place to ask your question on Windows CE 6.0 is in the MSDN forums for the development of Windows Mobile. Click here for a link to the Windows Mobile Development Forum.
  They are there, the experts and would be better able to solve your problem of Windows CE and help answer your questions.

• Oracle 10g, how to determine the memory allocated is healthy or sufficient.

  Hi guys,.
  
  I have a 10.2.0.5 production database.
  Currently, my server has 8 GB of physical RAM.
  / 3GB is allocated to the SGA and 1 GB for the PGA.
  Let's say a day is needed for the application (for example, weblogic) to increase the pool of connections from 20 to 50.
  How are we able to know if the memory allocated is sufficient for the existing load as well as the increase in workload?
  CPU is altogether would apply us we can generate on the CPU. If the load is low, I assumed is quite safe to increase the connection.
  Please share your experiences of dealing with this situation.
  
  Thank you

• Resizing of the memory allocated to the virtual machine

  Hello

  I use VMPlayer on a XP and Ubuntu invited crowd.

  I was wondering if I could resize the memory of my Ubuntu virtual machine by changing the value of the variable memsize in 512 to 1024 vmx configuration file or if something more complex needs to be done?

  Thank you very much.

  Yes, with the Machine virtual shutdown, not suspended, and it's best if you close the VMware product too.

• How to change the memory allocated for VCenter server, which is a virtual machine

  I'm trying reclassification of 3.5 to Vsphere 4.1 and I improved VCenter first, making it a virtual machine.  However, when I created the server I did not allocate enough memory for it and I'm getting errors.  How can I allocate more memory for the virtual machine while it is stopped?  I can not allocate more memory, except if it is closed, but with it being the VCenter server if I stopped him so that I can access with the Vi client.  Is there a service console command?  I searched for a few hours and found nothing.

  Thank you!!

  Discover what the vCenter ON WHAT VM ESX host is marked (e), connect directly to the ESX host and find the vCenter VM and make the change.

• Get the DLL string (memory allocated for DLL)

  Hi, I'm aware there are a lot of discussions around this topic, but there are a lot of variations and I've never used before LabVIEW, and I seem to have a hard time at a very basic level, so I hope someone can help me with the below simple specific test case to put me on the right track before I pull my hair remaining.

  I've created a DLL with a single function "GenerateGreeting". When it is called, it allocates enough memory for the string "Hello World!" \0"at the pGreeting of pointer, copy this string to the pointer and sets the GreetingLength parameter to the number of allocated bytes (in the DLL in the end, I want to use, there is a DLL function to free the memory allocated for this way).

  I created a header file to go with the DLL containing the following line.

  extern __declspec(dllimport) int __stdcall GenerateGreeting(char* &pGreeting, int &GreetingLength);
  

  I then imported the LabVIEW file using the import Shared Library Wizard. That created a "generate Greeting.vi' and everything seems somewhat sensitive for me (although this does not mean a lot right now). When I run the vi, the ' GreetingLength on ' display correctly '13', the length of the string, but "pGreeting out" shows only three or four characters (which vary in each race), place of the string that is expected of junk.

  The pGreeting parameter is set to the 'String' type, the string "String pointer C" format, size currently Minimum of 4095. I think the problem is that the DLL wants to allocate memory for pGreeting; the caller is supposed to pass a unallocated pointer and let the DLL allocates memory for the string the right amount, but LabVIEW expected the DLL to write in its buffer préallouée. How to with LabVIEW? Most of the functions in the DLL in the end, I want to use work this way, so I hope that's possible. Or I have to rewrite all my DLL functions to use buffers allocated by the appellant?

  The vi , header and the DLL are atteched, tips appreciated. Edit - cannot attach the dll or the headers.

  extern __declspec(dllimport) int __stdcall GenerateGreeting(char* &pGreeting, int &GreetingLength);
  

  Although char * & pGreeting is actually a thing of C++ (no C compiler I know would accept it) and this basically means that the char pointer is passed as a reference. So, technically, it's a double referenced pointer, however nothing in C++ Specifies that reference parameters should be implemented as a pointer at the hardware level. So free to decide to use some other possible MECHANISM that takes the target CPU architecture support a C compiler constructor. However, for the C++ compilers, I know it's really just syntactic sugar and is implemented internally as a pointer.

  LabVIEW has no type of data that allows to configure this directly. You will have to configure it as a whole size pointer passed as a pointer value and then use a call MoveBlock() or the support VI GetValuePtr() to copy the data on the pointer in a string of LabVIEW.

  AND: You need to know how the DLL allocates the pointer so that you can deallocate it correctly after each call to this function. Otherwise you probably create a leak memory, since you say that the first 4 bytes in the returned buffer always change, this feature seems to assign to each run of a new buffer that you want to deallocate correctly. Unless the DLL uses a Windows such as HeapAlloc() API function for this, it should also export a function according to deallocate the buffer. Functions like malloc() and free() from the C runtime cannot always be applied in the same version between the caller and callee, so that calling free() by calling on a buffer that has been allocated with malloc() in the DLL may not work on the same segment of memory and result in undefined behavior.

• Confusion over the memory of a bunch of Java and WLS_FORMS

  Hi all
  
  Background first:
  
  Oracle Forms/Reports 11.1.2 64-bit
  WebLogic Server 10.3.6
  JDK 1.6 update 37 64-bit
  Microsoft Windows 2008 R2
  Using nodemanager to start/stop the servers managed
  
  After reading all the documentation and searched this forum and the Internet for advice, I'm still totally confused about how best to make use of memory on the server (the server I'm working now on a 8 GB). Two trains of thought that I discovered in my research:
  
  (1) do not change the size of Javaheap at all (stick with the default values) and just create additional managed servers on the same machine.
  
  (2) increase the size of the heap Java for WLS_FORMS
  
  That said, here are my questions:
  
  (A) what is the best practice approach (#1 or #2)?
  
  (B) if it is the #2, what is the approved way to increase the heap size? I tried to add - Xms and arguments - Xmx to the WLS server begin arguments in the WLS console. They are applied when the managed server is started (confirmed in the log file), but because of the way WLS_FORMS is started, there are more - Xms and arguments - Xmx applied after mine, and peaks of Java one last mention if there are duplicates.
  
  1st update: Question #2 seems to be answered by the support notes 1260074.1 (the only place I had not yet looked at)
  
  Thanks for any idea that you can provide. If there is a document that I missed somewhere, I'm happy to be told where it is, and will read and summarize the results here.
  
  Kind regards

  John,

  I'll try to comment on each of your own:

  (1) we had been make some type errors "Unable to contact forms Apache Server" (users see the error "Failed to bridge APACHE server"). The logs showed nothing interesting. I increased the memory allocated using setDomainEnv.cmd, and the error seems to have disappeared. Yes, I know it's a shotgun approach, try something without really having a reason to do it, but it seems to have helped Edit: now I have review of OHS logs instead of WLS_FORMS newspapers, I found the log messages, which brings me to Doc 1380762.1, who tells me that I need a patch. DOH. Oh crikey, forms 11.1.2.1 is out and it came out shortly after that we have downloaded 11.1.2.0 to create these environments. Good and the bad new kind of thing...

  The Apache Bridge error is relatively in line toward the front if you understand what it is say you. It is an error generated by mod_wl_ohs which is the property of SST (Apache). This module is responsible for the relationship between OSH and WLS. The Apache bridge error means that OSH (mod_wls) has been unable to get a response from the managed server WLS he called. Basically, he was unable to cross the bridge ;) The cause could be anything from the managed server does work not, management server is busiest, or there is a problem of network configuration and the server simply didn t hear appeal of OSH.

  It is all described in Note 1304095.1 MOS

  Regarding 11.1.2.1, this can be installed fresh or as a patch on 11.1.2.0. So for machines which currently installed, you can go directly to 11.1.2.1 without having to first install 11.1.2.0.

  
  .

  (2) as tony.g suggested, we are looking for what we should do to solve them "I have n servers with x GB of RAM, what should I do to configure out-of-the-box forms for stability" issue.

  As I said, there is really no 'forms' specific settings associated with how much RAM your machine has. The only exception to this is (although a little indirect) to use the grouping of the JVM. JVM pooling can reduce the size of each execution process memory footprint by moving his calls from java to the pool of the jvm, then common queries of sharing with the other running execution environments. Memory, use of OSH or WLS managed server really has nothing to do directly with the forms. Specifically to the managed server, from a perspective of forms, I would not expect the cost of memory of WLS_FORMS spending a large part due to the workload. I'm expecting increase as the simultaneous load increases, but I would not expect it to be significant. If I had to guess, see an increase of 1 m or less per user wouldn't surprise me (that's just a guess - I don't know what would be the expected values). If we were to use our older scalability guidelines (Oracle), usually we would have suggested that you should consider about 100 sessions by 1 FMV for better performance. Given that v11 uses a newer version of java and scalability is better today, I suspect that you can easily spend a couple of hundred (300 for example) or more before the performance decreases. In addition, the need to add more managed servers would be probably necessary.

  This is discussed in Note 989118.1 MOS

  
  .

  (3) HA is important to us, so we set up a cluster of servers of forms/States with a BLT in front of her. I read in the literature on the management of clusters, cloning of a managed server and with the support, how to increase the memory heap for the WLS_FORMS server. My thought process was 'If Oracle gives me instructions on how to increase the heap memory and how clone managed servers, there must be a scenario in which do have advantage." I'm trying to understand the scenarios in which we would do either of these activities.

  Refer to the note that I mentioned above. As a general rule, if you limit the number of simultaneous sessions less than about 300-400, I think the default settings should be fine. If you think you want to go beyond 300 or 400 per managed server, then probably you need to increase the heap the managed server max. Yet once again, refer to the note that I mentioned earlier.

  See also Note 1260074.1 MOS

  I am aware of the JVM pooling (Yes yell us reports) - I still have to this implementation, but it is on my to-do list.

  This is discussed in the [url http://docs.oracle.com/cd/E38115_01/doc.111210/e24477/jvm.htm]Forms Deployment Guide

• Virtual machine consumes memory allocated all

  I have 4 ESXi 4.1 on Dell PE R610 servers. I used the installation ISO Dell from their support site media to install ESXi 4.1.

  I noticed that all virtual machines consume all the memory allocated to it.

  In other words, if I look at the memory of all resource allocation the VM is private.

  It has no memory shared to do so.

  I did not make reservations for the virtual machines.

  Someone at - it other ideas as to why this could happen?

  Thank you

  This "problem" has been discussed a lot already, see threads like these:

  http://communities.VMware.com/message/1487356#1487356

  In short:

  ESX 4.x use large memory pages by default. Find duplicates MB 2 pages for GST is almost impossible with them. You can set the Advanced setting mem.allocguestlargepage to 0 if you want to force the use of small pages, but ESX breaks down large pages under contention memory itself.

• The display of file space of total Information System Page after changing virtual memory allocation?

  I thought that I understood that I could set up a file.sys page on any available partition on Windows, if I wished, for example, to create more virtual memory or move a file to another drive. However the changes I make to my computer are not appearing in the system information, after a reboot - why is - this?

  I have successfully configured internal auxiliary training to take on a pagefile.sys when you use the system advanced settings in the computer file system properties. Page created on the auxiliary drive single file memory is equal to once and a half the size of the physical memory of the computer.

  As I had created a larger file of the Page on the auxiliary drive, I then decided to reduce the Page file on the boot up to 300 MB drive. When I did make changes, I clicked on the set then OK and then I rebooted the entire computer.

  After restarting the computer, I tried to check system information for a summary of the changes I had made to the file Page and virtual memory space and I was disappointed to see that the pagefile on the auxiliary drive does not show upward. Information system had just recorded space Page MB 300 in C:\pagefile.sys file, and there is no trace of the larger Page file that I created on the auxiliary drive. How is that?

  If I go back to the virtual memory window in advanced system settings, it clearly shows I changed two files Page. Yet in Information System shows only the boot Page file drive. How is that?

  I always use Internet Explorer with only 300 MB Page file space, and it works really faster than the default virtual memory allocation, however the system soon slows down after opening about 5 instances of Internet Explorer and the system starts asking to close application windows down to save memory. So why does the system not switch to use the Page file on the auxiliary drive?

• Memory not fully usable in the pool allocation?

  Hello

  We have a few "issues" with Org CDV is deployed under the pool allocation model. It is not possible to use the RAM allocated by 100% (or any value close to 100%). When you try to start the virtual machines, we receive an error for the allocation of resources of the vCenter (lack of resources...). It turns out when you look at the list of resources that 'Used a reservation' is greater than the sum of reservation of the virtual machines that is already running.

  Example of

  Org vDC has 13 GB of RAM allocated with 20% guarantee = list of resources gets 2662 MB of booking

  VM1 is configured with 5 GB RAM = Gets a booking of 1024MB

  VM2 is configured with 6 GB of RAM = Gets a booking of 1229 MB

  Sum of reserves VM = 2253MB

  Customers point of view, it seems that there are always 2 GB available RAM, RP views (calculated) there are still the 409 MB available that are 20% of the 2 GB of RAM. If the client sets up a new virtual machine with 2 GB, tries to start, but it does not work because of insufficient resources.

  When you look at the list of resources in detail, that it's somehow clearly why it fails. The used reserve is 2521 MB, so only 141 MB are available. It is about 700 MB usable for the customer.

  I think it has to do with the charge of the virtual machines, although the General value of resource pools does not explain this difference

  This also occurs when you use other percentages of RAM guaranteed.

  This behavior is - although somewhat understandable - boring.

  To avoid calls to the technical support of customers complain about this issue (in my opinion), there are 2 possibilities

  1. explain the situation/reason for customer and tell them to order more RAM. First of all I don't think that the majority will understand it or worries. And as long as we can't calculate how it takes over is a no go.

  2. Add a buffer to the quantity of RAM. It's what we right now - we add 10%. It works, but customers see that they have more available RAM that they ordered. Integration with billing is too difficult.

  Other vCloud Director users are aware of this issue, too? STI is expected to 'fix' that in future releases? As vCloud Director auto setting RP booking limits somwhow.

• iOS app breaks down at the return of cameraUI - a memory allocation problem?

  Hey all

  try to complete my first application

  When running on iOS, the application crashes SOMETIMES after returning from cameraUI ("use" / MediaEvent.COMPLETE or cancel "/ Event.CANCEL" "").

  When I leave some other applications running on my iPhone 3 g (and not many are open), the problem goes away, which makes me think it is a problem of memory allocation

  in this aspect, can I trust the iOS to leave inactive applications to allocate more memory for my, currently active, AIR application?

  (there is no memory leak)

  This is a version of os running iPhone 3Gs 4.3.5

  the app is made with Flash Pro 5.5 overlaid with AIR 3.1 sdk and deployed by using the "deploy to app store" type (which should be the most free)

  (no crashes on Android or desktop versions)

  someone had this problem of cameraUI or a similar where an application crashes if more then some numbers of applications are open?

• Issues of memory allocation?

  In the 2 years I was using my Droid X, I never had any warning on the memory usage. When I created my Razr, it was loaded with less games and other programs that the X.

  Today, I got a caution icon indicating "Low on space of the volume. This picture gave me the opportunity to move photos, movies and songs on the removable SD card, or launch the file manager to delete or move the files manually. It lists 0 files that meet these criteria.

  Under settings/Applications/Running Applications, my benefits are as follows:

  • Downloaded: 796 MB used / 2.3 GB free
  • ALL: 762 MB used / 2.6 GB free
  • Media (internal storage) space: 8 GB used / free 0.00
  • Running: 288 MB used / 400 MB of free space

  I do not understand this allowance, or why I'm off space on the Razr when it never happened to me on the Droid X. I would appreciate a discussion and an explanation of how the memory is allocated in the Razr and what can I do to solve this problem.

  Thanks in advance!

  
  

• buffer allocation and minimizing memory allocation

  Hello

  I am tryint to minimize the buffer allocation and memory in general activity. The code will run 'headless' on a cRIO and our experience and that of the industry as a whole is to ellliminate or minimize any action of distribution and the dynamic memory deallocation.

  In our case we treat unfortunately many string manipulations, thus eliminating all the alloc/dealloc memmory is significant (impossible?).

  Which leaves me with the strategy of "minimize".

  I did some investigation and VI of profiling and play with the structure "on the spot" to see if I can help things.

  For example, I have a few places where I me transpoe a few 2D charts. . If I use the tool 'See the buffer allocations' attaced screenshot would indicate that I am not not to use the structure of the preliminary examination International, both for the operation of transposition of the table for the item index operations? As seems counter intuitive to me, I have a few basic missunderstanding either with the "show stamp" tool of the preliminary examination International, or both... The tool shows what a buffer is allocated in the IPE and will once again out of the International preliminary examination, and the 2D table converts has an allowance in and out, even within the IPE causing twice as many allowances as do not use REI.

  As for indexing, using REI seems to result in 1.5 times more allowances (not to mention the fact that I have to wire the index numbers individually vs let LabVIEW auto-index of 0 on the no - IPE version).

  The example illustrates string conversions (not good from the point of view mem alloc/dealloc because LabVIEW does not determine easily the length of the 'picture' of the chain), but I have other articles of the code who do a lot of the same type of stuff, but keeping digital throughout.

  I would be grateful if someone could help me understand why REI seems to increase rather than decrease memory activity.

  (PS > the 2D array is used in the 'incoming' orientation by the rest of the code, so build in data table to avoid the conversion does not seem useful either.)

  QFang wrote:

  -My reasoning (even if it was wrong) was to indicate to the compiler that "I do not have an extra copy of these tables, I'll just subscribe to certain values..." Because a fork in a thread is a fairly simple way to increase the chances of duplications of data, I thought that the function index REI, by nature to eliminate the need to split or fork, the wire of the array (there an in and an exit), I would avoid duplication of work or have a better chance to avoid duplication of work.

  It is important to realize that buffer allocations do occur at the level of the nodes, not on the wires. Although it may seem to turn a thread makes a copy of the data, this is not the case. As the fork will result in incrementing a reference count. LabVIEW is copy-on-write - no copy made memory until the data is changed in fact, and even in this case, the copy is performed only if we need to keep the original. If you fork a table to several functions of Board index, there is always only one copy of the table. In addition, the LabVIEW compiler tries to plan operations to avoid copies, so if several branches read from a wire, but only it changes, the compiler tries to schedule the change operation to run after all the readings are made.

  QFang wrote:

  After looking at several more cases (as I write this post), I can't find any operation using a table that I do in my code that reduces blackheads by including a preliminary International examination... As such, I must STILL understand IPE properly, because my conclusion at the present time, is that haver you 'never' in them for use. Replace a subset of a table? no need to use them (in my code). The indexing of the elements? No problem. .

  A preliminary International examination is useful to replace a subset of the table when you're operating on a subset of the original array. You remove the items that you want, make some calculations and then put back them in the same place in the table. If the new table subset comes from somewhere other than the original array, then the POI does not help. If the sides of entry and exit of International preliminary examination log between them, so there no advantage in PEI.

  I am attaching a picture of code I wrote recently that uses the IPEs with buffer allocations indicated. You can see that there is only one game of allowances of buffer after the Split 1 table D. I could have worked around this but the way I wrote it seemed easier and the berries are small and is not time-critical code so there is no need of any optimization. These tables is always the same size, it should be able to reuse the same allowance with each iteration of the VI, rather than allocate new arrays.

  

  Another important point: pads can be reused. You might see a dot of distribution on a shift register, but that the shift register must be assigned only once, during the first call to the VI. Every following call to the VI reuses this very spot. Sometimes you do not see an allocation of buffer even if it happens effectively. Resizing a table might require copying the whole table to a new larger location, and even if LabVIEW must allocate more memory for it, you won't always a point of buffer allocation. I think it's because it is technically reassign an existing table instead of allocating a new, but it's always puzzled me a bit. On the subject of the paintings, there are also moments where you see a point to buffer allocation, but all that is allocated is a 'subfield' - a pointer to a specific part of an existing table, not a new copy of the data. For example 1 reverse D table can create a sub-table that points towards the end of the original with a 'stride' array-1, which means that it allows to browse the transom. Same thing with the subset of the table. You can see these subtables turning on context-sensitive help and by placing the cursor on a wire wearing one, as shown in this image.

  

  Unfortunately, it isn't that you can do on the string allocations. Fortunately, I never saw that as a problem, and I've had systems to operate continuously for months who used ropes on limited hardware (Compact FieldPoint controllers) for two recordings on the disk and TCP communication. I recommend you move the string outside critical areas and separate loop operations. For example, I put my TCP communication in a separate loop that also analyses the incoming strings in specific data, which are then sent by the queue (or RT-FIFO) to urgent loops so that these loops only address data of fixed size. Same idea with logging - make all string conversions and way of handling in a separate loop.
