Maximum size of an array

Hello,
I'm using LabVIEW2009 under windows XP (4Go RAM).
When I create a large array using the "Initilaize an array" fucntion (for example a 2D 512x512 array of U16), I've an error message "Insufficient memory" while this table weighs only 520kb if I try to use it (for example, save it to a binary file). My final need if a 2D 512x512 array of double precision.
Is there a maximum size for array in LabVIEW? If yes, could we modify it?
Thank you in advance,
Eric

That's very strange, you are correct the array is not that big.
Is your code making a lot of copies of the array?
Can you initialize the array on a fresh start:
-Reboot your PC
-Start LabVIEW
-Create an empty VI
-Place the initalization inside this VI
Run code.
One thing to advice, make one of your constants a control, this will prevent LabVIEW from doubling the memory upon editing the array in memory.*
Ton
*When you initialize an error with only constants LabVIEW will make the array a Constant in memory, when you edit the array, LabVIEW needs to declare a copy. This is very usefull for read-only (lookup) array.

What's the maximum size of an array in labview? LV run out of memory

I want to create a 1D array of 40M element of Double: so I use Initialize Array, element is double 1, dimension size is 40M (and put a Sum at the end so as to make sure lv do attempt to create that array). Supposed this only need 320M of memory, and my system has over 1G free memory available as shown in Task Manager, but when Labview runs this VI, it tells me "Not enough memory to complete this operation" "Labview: memory is full, top level VI is stopped at Initalize Array", so it seems LV is unable to handle such an array, even if there is apparently more than enough free memory in the system.
Does anyone know why labview fails to allocate memory for this VI? Anyway to solve this problem?

This question has been asked many times. Have you tried to do a search? Arrays require contiguous memory. It doesn't matter if you have 40 GB of RAM. Unless you have a contiguous block for your array, the allocation will fail. You should read the chapter in the LabVIEW Help on managing large data sets. There are also a couple of KnowledgeBase articles.
Of course, the obvious question is: why do you need to create such a large array in the first place?

What is the maximum size of indexed array that can be created during execution of while loop?

Hello,
I am using a ring acquisition to take in images. If i write them as files in the loop, it slows down the acquisition unacceptably. Therefore i am converting image to array and storing the array until the acquisition is complete and then reading the array and converting back to image to save. The program sometimes runs out of memory (after a couple of minutes). Can anyone think of a way where i can store the array/images within the execution (without losing image information), without slowing it down and to avoid this memory problem?
I have included the VI.
Thanks in advance for any help or advice.
kindest regards,
FraserD

When you build the array of pictures you do it using auto-indexing out of a while loop. That means that memory is aquired for a copy of the previous picture array and the array is rebuilt on every iteration, this is slow and requires a lot of extra memory.
If you want to speed things up try initializing a shift register with a 3D array of a size that will be able to hold a certain number of pictures, then replace the "pages" as new pictures are aquired, replace operations do not require copying of the previous array and will thus be much much faster. The difference is exeptional when dealing with large arrays/amounts of data.
Now, the shift register buffer could be built into a functional global, and you can add a push/pop logic to it so that you can have a p
arrallell loop that works on writing the elements to disk. You could use a que for this, but I think even though you specify a size limit to the que it still aquires memory as new elements are added (correct me if I'm wrong people...:-)), so a functional global acting as a circular buffer og fixed size frame for a que should be better.

Maximum size of a virtual pool in SCVMM 2012R2

I have a Windows Server 2012 R2 running SCVMM
2012 R2 and an over-committed virtual storage pool. In Server Manager the capacity of this storage pool is 128TB which
translates to 140TiB which makes sense since the maximum allowed size by the storage array is 140TiB.
This same storage pool is shown under VMM with the size of 131,072GB (131TB)
which is 144TiB.
Where is this size coming from? Is this the maximum size allowed by the SCVMM? Or does SCVMM use
different measurement units?

Hi,
You can see the actual limit and also modify it using Siebel Tools. In your case, when you're talking about Contacts, the desired BC is "Contact Attachment".
-> Open Siebel Tools -> Business Component -> "Contact Attachment" -> Field -> "ContactFileSize" -> Check Property "Validation".
e.g. if Validation is "<= 5000000" it means that file can have a maximum size of 5 MB.
Adjust to your needs.

Keeping Unique 1D Size in 2D array

Is there a way to force Labview to maintain the original array dimension independently from one another when creating 2D or even possibly 3D arrays? It appears to be autosized every set of inputs to the maximum size. But I want to maintain each set of array size independent from one another. How do I do that?

Sure. Here is a screenshot showing buffer allocations. Note the extra copy of the cluster using the traditional extraction of a single element from the array of clusters of arrays. It is not there if using the In Place Element. Code is is LabVIEW 8.5 (when the In Place Element was introduced).
Note that in LabVIEW 2009, the buffer viewer will show a buffer on the output of the index array in the In Place Element. This buffer is not a full copy, but a static allocation to handle indexing an out-of-bounds element.

Export buffer maximum size

Hi,
For the parameter buffer used in export what is the maximum size we can give as input.

BUFFER
Default: operating system-dependent. See your Oracle operating system-specific documentation to determine the default value for this parameter.
Specifies the size, in bytes, of the buffer used to fetch rows. As a result, this parameter determines the maximum number of rows in an array fetched by Export. Use the following formula to calculate the buffer size:
buffer_size = rows_in_array * maximum_row_size
If you specify zero, the Export utility fetches only one row at a time.
Tables with columns of type LOBs, LONG, BFILE, REF, ROWID, LOGICAL ROWID, or DATE are fetched one row at a time.
Note:
The BUFFER parameter applies only to conventional path Export. It has no effect on a direct path Export. For direct path Exports, use the RECORDLENGTH parameter to specify the size of the buffer that Export uses for writing to the export file.
Example: Calculating Buffer Size
This section shows an example of how to calculate buffer size.
The following table is created:
CREATE TABLE sample (name varchar(30), weight number);
The maximum size of the name column is 30, plus 2 bytes for the indicator. The maximum size of the weight column is 22 (the size of the internal representation for Oracle numbers), plus 2 bytes for the indicator.
Therefore, the maximum row size is 56 (30+2+22+2).
To perform array operations for 100 rows, a buffer size of 5600 should be specified.

Size restrictions on arrays and vectors

Hi all!!!
I want to know whether there is any restriction on maximum size of array and vectors.
If I have thousands of records to be displayed on browser through JSP, can I initialise the arrays/vectors with that no.
Whether it will have adverse effect on performance.
Thanks in anticipation

Array lists (and vectors) use an array as backing data store. And since array indices are ints, the maximum number of elements in an array list is Integer.MAX_VALUE (2 ^ 31 - 1).
About the performance: if you know how many elements you are going to add (albeit not precisely), you can create the array list with an initial capacity. This will improve performance because a new array is created when an element is to be added but the capacity has been reached.
Kind regards,
Levi

Set Maximum size for a subpanel created with splitter bars in LV8

Does anyone know how to set the Maximum size for a subpanel created with asplitter bar? If I show one cluster in the subpanel and use the scroll bar to scroll, I can see more (blank) area than I want. I just want the user to be able to scroll a cluster within a subpanel while the cluster is larger than the view area of the subpanel. I don't want to let the user scroll outside the cluster.
Ravi Beniwal

I apologize for the mixup in terminology. Please read Pane wherever the word Subpanel was used.
Please see the attached VI for a description of my problem.
I would really appreciate any help with this.

Set maximum size in Text Form Field Options for a field in bi publisher RTF

Hi All,
How to set maximum size in Text Form Field Options for a field in bi publisher RTF.
I have a RTF whch is having a field in that i need to add some validation condition but after adding certain condition in Add help text tab ,it is not accepting after certain length, how i can increase the length to unlimited,please help me on this
Thnaks

Form fields have some restrictions if your are using version lower than 11g.
They can accommodate only 393 chars. You can add the text in both status bar and help key, which can in total consume 393 chars.
If your code logic is more than that, it can be split into multiple form fields as Avinash suggested or you can use sub template logic and handle coding over there. Again in sub template code can be within/outside form fields.
So there is no option for user to increase the size of form field.

SharePoint Foundation 2010 maximum size WID

Hi,
I've installed SharePoint Foundation 2010 using the Windows Internal Database. I'm a bit confused about the maximum size of the database. On several websites I read that the max size for an SQL express database is 4GB.
Is this the same as the Windows Internal Database? Or can it grow bigger?

Are you sure you mean the Windows Internal Database? The SharePoint foundation installer will install SQL Server Express edition.

Windows Server 2008 R2 Security Event Log Maximum Size

I have a customer with logging requirements on domain controllers that are exceeding the maximum log size they have configured for the security log. When they attempted to increase the maximum size of the security event log via Group Policy, the settings
did not take effect. When an attempt was made to increase the security event log manually on the domain controller via the properties of the log, an error is generated whenever the value was changed.
The Maximum Log Size specified is not valid. It is too large or too small. The Maximum Log Size will be set to the following: 196608 KB
The 196608 KB value is the value that it is currently set at. Testing on other logs, application, system, has lead to the same result.
wevtutil.exe sl security /ms:<n> produces similar results. There is no error message given but the value doesn't change when you run wevtutil.exe gl security
When viewing the registry value MaxSize under HKLM\Current Control Set\Services\EventLog\Security the change is reflected, but the log does not seem to get any larger.
What one would expect to be a two minute change in a group policy object has turned into something much more difficult. Any idea what could be causing this?
Joseph M. Durnal MCM: Exchange 2010 MCITP: Enterprise Messaging Administrator, Exchange 2010 MCITP: Enterprise Messaging Administrator, MCITP: Enterprise Administrator

I verified that it was not another policy - the domain is pretty simple without many policies, only policies applied are:
Default Domain Policy (no event log settings)
Company Domain Policy (no event log settings)
Default Domain Controller Policy (no event logs settings)
Company Domain Controller Policy (...\Event Log\Maximum security log size 4194240 kilobytes)
The value was 196608 before, the plan was to change the group policy setting to 4194240 and I expected it to be that easy. However, the values didn't change.
4194240 is divisible by 64
Used multiple tools to try and change
Group Policy
Event Viewer
wevtutil.exe
registry editor
While some of the methods display a larger event log, the actual size of the event log still seems to be limited to 196608 kb.
Thanks,
Joe

How can i increase the maximum size of a text column in Access

hello,
i am inserting data in the MS-Access database through my servlet and am getting the exception whenever the length of the text data is more than 255 characters as in Access the maximum size for character data column is 255 can anyone tell me if there is any way by which i can increase the maximum limit of the column size in Access ,i.e. to make it more than 255.

A text field in Access has a maximum size of 255 characters. If you want to store text information in Access larger than 255, you need to use the memo rather than text data type. There are special considerations for using an Access memo data type and accessing it through JDBC. Specifically, I believe it must be accessed as a binary object (BLOB), rather than text when using the JDBC-ODBC bridge. There are lots of discussions within these forums regarding how to manage, and the issues with using the Access memo data type.
Good luck!

I want to set a maximum size for pictures when FF shows websites. How can i do that? NO I DONT MEAN "HOW TO ZOOM".

I have FF 34 but this problem has been there for a lot of earlier versions. On many webpages there are pictures that cover my whole screen, and I want to set maximum size for showing images on webpages.
I ONLY wanr to change the maximum size of the images, AND IAM NOT asking about how to zoom the webpage.

Do you want to hide large images or merely make them smaller by setting a max-width and max-height?
You would probably have to use JavaScript (bookmarklet) to achieve this reliably.
There are bookmarklets to make large images fit in the window to avoid a horizontal scroll bar
You can try this code in the userContent.css file (adjust the max-width accordingly).
*http://kb.mozillazine.org/userContent.css
<pre><nowiki>img { max-width: 1024px !important; height: auto !important; }</nowiki></pre>
The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.
*http://kb.mozillazine.org/Editing_configuration
*Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
*Use a plain text editor like Notepad to create a (new) userContent.css file in the chrome folder (file name is case sensitive)
*Paste the code in the userContent.css file in the editor window
*Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userContent.css. Otherwise Windows may add a hidden .txt file extension and you end up with a not working userContent.css.txt file

Forms: How to set a maximum size in Text Fields with automatic size

¡Hi!
When I set a text field on my forms and I use automatic size for te text that the user can write, if the user don't need more space than the field size, when the text appears, Adobe Acrobat Pro always set the text-size to 14 or higher. How can I set a maximum size for that text? For example... 12 or 10...
Thank you very much,
Best regards from Spain,
David.

Ok. If I use a single line text field, changing the height of the field seems to be a simple way to solve the problem, but... what should I do when the fields are multi-lineal?
Thanx for your quick answer.
