The current size of the shared memory

• Setting the shared memory size linux

  Hello
  I'm a bit confused on the parameters of the kernel, can you please share your views on this one please.
  Shared for the tt in the linux kernel memory is calculated as follows:
  Shared mem = perm size size temp + journal + fresh size generals 7 MB
  
  but when I look at the linux sysctl.conf, I saw that there is a great value for sharing memory setting (default) as ~ 68 GB, then I think that I should not override/decrease this value. What is your opinion? Setting the value default (68 GB) helps my DB behave badly? Or by assigning the value calculated as in the equation makes them much faster?
  
  # Control the maximum shared segment size, in bytes
  kernel.shmmax = 68719476736
  kernel.SEM = 250 32000 100 100
  
  # Control the maximum number of shared memory pages segments
  kernel.shmall = 4294967296
  
  Thank you very much.

  The shmmax kernel parameter simply sets a limit on the maximum size of a shared memory segment individual. It has no direct effect on performance. In general, it should be set large enough to allow the largest shared memory segment you need to create but smaller then the amount of physical memory in the machine. Shmall parameter sets a limit of large system on the total amount of shared memory (all active segments added) can be allocated. It must be also, in General, lower then the [physical memory on the computer.

  If one is defined on more memory in the machine is not an immediate problem. However, in this case, it is possible to create shared memory that is larger than the physical memory of the system (as far as adequate swap space is configured), and if this happens then the overall performance of the system will be affected, probably seriously.

  Thus, work on what you need and set accordingly.

• 836: failed to create the shared memory data, error 22 store segment

  Hi, I am new to timesten and databases in general, and I'm testing the database timesten to test.
  
  I am running ubuntu linux in virtualbox and have java 6 is installed. So far, I installed the timesten database and configured the sys.odbc.ini to create a new database. However, it seems that I can't connect to a database.
  
  I connect with the orattadmin of the user (which belongs to groups both timesten and ttadmin)
  
  I run the commandes./ttenv.sh and I have the classpath for ttjdbc6.jar in it.
  then I run le./ttisql.sh, and when I try to connect to mydatabase or any other database present in the sample folder I get:

  836: failed to create the shared memory data, error 22 store segment
  The command failed.
  
  what I am doing wrong? What can I do?
  
  Thanks for your time

  A data store active TimesTen consists of a single shared memory segment allocated from o/s. The size of this segment is PermSize + TempSize + LogBufMB + ~ 20 MB. This allowance will not allow the o/s unless the 'package' kernel parameter has a value greater than the requested size of the segment. According to the Guide of Installation TimesTen, you set various parameters of the kernel on the appropriate values (memory shared, semaphores, etc.).

• TimesTen does not release the shared memory even after DB destroy

  Hello
  
  After that TimesTen DB is destroyed, the shared memory allocated to the DB is not to be released by the system.
  We use TimesTen release 11.2.1.7.0 (64-bit, Linux/x86_64)
  
  We need to restart the system for shared memory usage (outdated) by clearing TimesTen.
  
  Please let me know what is the problem here.
  
  Concerning
  Pratheej

  Hi Pratheej,

  How are actually destroy you TimesTen? are you using ttDestroy? It seems that you may force a shutdown of the master demon TT? In which case the current connections will not aware the master demon went so far that they try then access TT until they can keep the memory shared memory segment.

  Take a look at ttStatus to see which links are open. Unplug them all by default that TT will come out then memory, you can use ttDestroy.

• Change the shared memory in the Bios for the graphics - Satellite C660 217

  There is no setting in the BIOS that I can find.

  BIOS is up to date

  Hello

  It is not possible.

  Shared memory is assigned automatically and this is controlled by the graphics driver.
  But the shared memory is only used if the applications (IE game) would require more graphics RAM.

• Satellite Pro C660 - 21 d - how to change the shared memory graphic value?

  My dxdiag screen says I have almost 1700 MB of video memory, but when I try to use this memory on games these games can use 256 MB...

  I tried to change settings in the BIOS, but it does not have this setting, do not know what else could cause this problem?

  Hello

  This could be confusing, but this isn't a problem.
  Shared memory is controlled by the graphics driver and the driver affects the part of the main memory to the memory of the graphics card ONLY if its required by a running application.

  The Dxdiag shows you how much RAM could be shared and value of memory in the quizzes you shared memory which is used and who is in the game right now.

• Satellite A660/07R - change the shared memory

  I have an A660/07R y at - there a way to change the system memory that is shared on this subject, he has a card geforce 350 m 3d mink?

  Hey Buddy,

  Shared memory quantity can't be changed because it will be controlled automatically.

  But I m wondering why you ask for this as far as I know the Satellite A660 with nVidia GT350M card has own graphic memory (1 GB). This memory will be the only graphics card.

• Workload of Orion - failed to create the shared memory

  I am struck after publication using Orion:

  . / orion - run oltp

  ORION: ORacle IO numbers - Version 12.2.0.0.0

  Unable to create a shared memory (orion_setup_shmem:skgmcreate)

  Additional information: 6000

  Additional information: 1

  orion_parse_args: orion_setup_shmem failed

  I use RDBMS_MAIN_LINUX label for the use of orion.

  I noticed a similar question, but that was the 11 series Oracle.

  Can someone please provide an idea on how to solve it? TIA!

  I thought about it (thanks to Sebastian for her, rather). It has nothing to do with the version of Orion.

  I have checked/proc/meminfo and found that HugePage = 0.

  Set it to something (say 100) of the root user: echo 100 >/proc/sys/vm/nr_hugepages and fix it!

• Premiere Pro, After Effects CS5 and the shared memory pool

  This feature works fine in Win 7 x 64. I think adding more RAM and going up to 12 GB. However, I noticed that CS5 sharing memory pool is limited to 75% of the physical RAM installed. Even if that makes sense, if you have a computer with the minimum requirements of 4 GB (because Windows itself will use a little less 1 GB + /), it makes less sense to 12 GB, where 9 GB is all you can use for the pool of CS5.

  Is this the way it works, or is it possible that I can be 'greedy' and go the number of 75% for larger amounts of physical RAM? It helps to have as physical RAM as much as possible for AE previews high resolution, etc..

  It is by design.

• Change the shared memory size of the integrated graph

  Hello world

  I just updated my X 200 with 4 GB of RAM and noticed that the integrated graphics card Intel grabs a set of GB, which I think is too much.

  Is it possible to tell how much memory, it allowed to use the integrated graphics card?

  Thanks in advance.

  No, it isn't. RAM allocation, not the user management system.

• Re: Satellite L300-255: how to increase the shared memory graphic

  Hello

  My laptop is Satellite L300-255. I have improved it's ram to 4 GB. I want to increase the graphics card 1 340 MB. In the specifications of the laptop, he said that the graphics card can increase if the Ram has increased to 3 GB

  Hello

  Shared graphics memory is controlled by GPU driver. You cannot add or edit it manually.

  More depends on the Windows OS you use, because the 32-bit system can manage max 3.2 GB of system memory.

  For example:

  * (32 bit OS) *.
  System memory: 2GB | 4 GB
  Dedicated video memory: 128 MB | 128 MB
  Shared system memory: 702MB | 1214 MB
  TOTAL available graphics memory: 830MB | 1342 MB

  * (64 bit OS) *.
  System memory: 2GB | 4 GB
  Dedicated video memory: 128 MB | 128 MB
  Shared system memory: 702MB | 1631 MB
  TOTAL available graphics memory: 830MB | 1759 MB

  Hope I could help you

• Satellite L650-16W: how to change the GPU shared memory

  Hi all

  I have a question about my L650-16W:

  How can I set the size of the memory shared of the ATI Mobility Radeon HD 5650?

  I look at my system bios, but it seems that it is not possible to define the shared memory...

  > I watch my system bios but it seems that it is not possible to define the shared memory...
  You are right. It is not possible.
  You cannot change the value manually... it s controlled by driver graphics card and everything works automatically.

• Details on the implementation of shared memory to set memory_target on Oracle Linux

  Hi all.

  I have a database of Oracle 11 g Rel2 (11.2.0.4) 64-bit running on Oracle Linux 5.8 64-bit.

  Several notes on MOS, must properly configure the shared memory to make use of automatic (memory_target) memory management.

  On these notes basically to allocate memory: Mount size of t tmpfs-o shmfs = 1073741824/dev/shm

  And keep the overall starting value by adding an entry in/etc/fstab: shmfs/dev/shm tmpfs size = 1073741824 0

  My doubt is that oracle Linux uses tmpfs instead of shmfs:

  [oracle@union ~] $ df-h/dev/shm

  S.ficheros Tamaa±o Disp Uso % Montado used in

  tmpfs 7, 9G 0 7, 9G 0% / dev/shm

  [oracle@union ~] $

  [oracle@union ~] Mount $

  / dev/map/VolGroup00-LogVolroot on / type ext3 (rw)

  proc on/proc type proc (rw)

  Sysfs on/sys type sysfs (rw)

  type devpts on/dev/pts devpts (rw, gid = 5, mode = 620)

  / dev/sda1 on/U01 type ext3 (rw)

  / dev/sdb1 on / boot type ext3 (rw)

  tmpfs on/dev/SHM type tmpfs (rw)

  None on/proc/sys/fs/binfmt_misc type binfmt_misc (rw)

  sunrpc on/var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

  / dev/sdc1 on/media/respaldos type vfat (rw)

  [oracle@union ~] $

  [oracle@union ~] $ cat/etc/fstab

  / dev/VolGroup00/LogVolroot / ext3 defaults 1 1

  LABEL = / u01/U01 ext3 defaults 1 2

  LABEL = / boot/boot ext3 defaults 1 2

  tmpfs/dev/shm tmpfs defaults 0 0

  devpts/dev/pts devpts gid = 5, mode = 620 0 0

  Sysfs/sys sysfs defaults 0 0

  proc/proc proc defaults 0 0

  / dev/VolGroup00/LogVolswap swap swap defaults 0 0

  As you can see it's ride on tmpfs/dev/shm tmpfs defaults 0 0

  
  

  So the question is: is it the same? is tmpfs just a label? After all this is pointing to/dev/SHM and tmpfs.

  
  

  Best regards, Luis.
  

  I have this line in/etc/fstab on OEL 6.5 system that I use now to give me 4 GB shared memory:

  tmpfs

  / dev/shm

  tmpfs defaults, size = 4000 m

  0 0

• Use of the video memory Inspiron 580

  I got a STD Inspiron 580 on 2 years ago and I've recently upgraded the video card integrated with a GeForce GT630 2 GB card. Now I am checking the use of memory for my system, now that I have an equipped graphics card, is it possible to change the dedicated graphics memory and shared system memory because it would free up on my machine, which is currently 4 GB of RAM.

  Will also change the foregoing slow aspects of my computer down?

  Hi KRIS537,

  Inspiron 580 system BIOS doesn't have an option to change the shared memory. It is handled automatically by the system and is disabled if a video card is detected on the system. You can follow the steps below to check the memory available in the system configuration:

  • Turn on the system
  • Press F2 on the Dell splash screen
  • Highlight the system information and press enter
  • You can find the installed memory and available memory .

  

  I hope this helps. Answer please if you have any other questions.

  Hello

  As I know the laptop is equipped with the AMD Radeon HD 6250 graphics card.
  Here, you could find nice description of this GPU:
  http://www.notebookcheck.NET/AMD-Radeon-HD-6250.40958.0.html

  But back to the main issue: shared graphics card memory is controlled by the graphics driver and everything works automatically and this means that the shared memory can be assigned manually :(
