Maximum size of a single update metadata.

Hi,
I have written a tool to parse WSUS update file, it parses a single update each time. But my tool takes a huge amount of memory for some updates, as they are large in size. For a update on windows8, the metadata size of a update is 18Mb. I wanted to know if
there some maximum size limit on the size of the metadata, for a single update.
Thanks,
Suraj

Hi,
Based on one of the documents from SAP,
When you are creating dimensions for your application set you should be aware of the following maximums for any one dimension.
u2022 The maximum number of fields in a table (a dimension = 1 table) is 1024.
u2022 The maximum record size is 8064 bytes (a record = 1 row in a table)
The two maximums above relate to the underlying SQL database in which BPC information and data is stored. They need further explanation as to how they relate to a BPC dimension. In BPC a field equals a property. So you can have up to 1024 properties in a dimension. One other factor that has an impact on the actual number of properties you can have in a dimension is the number of levels you have defined. SQL Server creates a set of properties for each level within the dimension. For example, you have 10 properties and three levels in your dimension, your total number of fields is 30. The second limiting factor is the size of the record. To determine record size you have to figure out the number of bytes (a byte equals a character) in each level. Since levels are repeated you only need to figure out the number of bytes in the first level and then multiply that number by the number of levels. To come up with the total number of bytes for a level you simply add up the field size for each field and multiply it by 2 (1 character = 2 bytes).
Hope this gives you some idea.

  • Is there a maximum size limit for a single file?

    I haven't been able to find a statement of the maximum size of a file. We're looking at storing several 5-10gb files in one file library.
    Is it possible?
    How badly would that impact performance?

    maximum size of a file. All files are stored as Binary Large Objects (BLOBs), A BLOB max size is (4 gigabytes -1) * (the value of the CHUNK parameter of LOB storage). Oracle Content Services configures its LOBs to have a 32K chunk size
    Note that there is a overhead by storing large files, you should compress your files if possible before storing them.

  • 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.

  • Maximum size of a JComboBox in a GridBagLayout

    I'm having a problem with a JComboBox inside a GridBagLayout. The general layout is a GridBag with labels / combo / textfields on the first line, a large table in a scrollpane that takes all columns on the second line, and a few labels / combo / textfields on the third.
    As long as the combo on the first combo is empty, it looks fine. When it gets populated, the combo gets resized to the size of the largest text. I would like to have it smaller and truncate the text.
    I tried to set maximum size, but the GridBag doesnt care. I've been trying with weightx but no success.
    What should I do ?

    And I would be interested which LayoutManager you prefer using.I don't use a single Layout Manager. I use a combination of Layout Managers to do the job. Thats why this question doesn't have a specific example. Remember LayoutManagers can be nested. The default layout manager for a frame is a border layout. That great for the general look of your application.
    a) you add a toolbar to the north
    b) you add a status bar to the south
    c) you add your main panel to the center.
    the main panel in turrn may use nested panels depending on your requirements. I don't do a lot of screen design but I typically use BorderLayout, FlowLayout, GridLayout and BoxLayout. GridBagLayout and SpringLayout have too many constraints to learn and master. They may be good for a GUI tool that only uses a single layout manager for the entire GUI, but I believe a better design is to break down the form into smaller more manageable areas and group components and use the appropriate layout manager for the group. That may or may not be a GridBagLayout for the small group, but I don't think you should force the entire form to use a GridbagLayout.

  • Maximum size HardDrive for Ultra 30

    Does anybody know what the maximum size harddrive is for an Ultra 30.
    I've been able to put a 40+ gig harddrive into an Ultra 5, but the Uktra 30 does not seem to accept a 38+ gig harddrive. It gives a trap error that I can't remember off hand.
    Thank you,
    James

    Hello James,
    larger disks (> 36 GB) should work fine. You might even use one of these 143 GB drives that cost a multiple of what the Ultra 30 is worth.
    Reseat the harddisk, then use probe-scsi-all at the ok-prompt. Is the harddisk detected ?
    Probably your drive was previously used with another operating system and therefore contains partition information (label) that Solaris doesn't like.
    Unfortunately your description is very vague. When did the problem appear (during booting from the first harddisk, when this drive was inserted in the second bay OR when invoking format after booting from CD) ? Maybe the drive is damaged and interfers with the other devices on the SCSI bus (first harddisk, CD-drive).
    In the first case install this harddisk (temporarily) in the first bay (the original one removed) and boot from CD (into single-user mode with verbose display). If the boot fails, the harddisk is bad.
    In the second case it might help if you remove the partition information when installed in the previous system (PC).
    Happy New Year !

  • Maximum size for autoflow?

    Hi,
    Is there a maximum size for autoflowing documents? Or possibly a maximum complexity?
    We have a large Word docx document, with many (400+) footnotes and a few cross-references. On trying to import it to ID CS5, it manages to import the text (the first page arrives, and we get a missing fonts message); but as soon as we try to autoflow throughout the rest of the document, the program freezes.
    I've been slowly paring the document down to smaller and smaller sizes, but anything over about 60pp in Word seems to freeze InDesign's autoflow.
    I've tried saving the Word files out as RTF files: this seems to help, and we can place up to about 160pp, but that's still a very long way short of the complete document.
    I've also tried saving the Word files out to Word 2003 format; that doesn't seem to do as well as the RTF files.
    If I break down the Word files into chunks small enough for ID to handle, then the autoflow works fine: but then we have to go through and replace all the cross-references that have been put in by the original author, as they end up referring to different Word files (which isn't possible, as far as we can tell).
    So, is there an upper limit on the file size that we can place, or just a limit on the number of footnotes or cross-references that we can import? Or could it be (in a unsurprising way) that I'm missing something really obvious?
    Thanks in advance,
    Dave

    A maximum on the number of footnotes? Hmmm ... Okay, let's try. (Several minutes of frantic copying later:)
    (That's in CS4, not '5, but since there are no improvements in the footnotes I'm fairly certain it didn't get worse either.)
    Both CS4 and CS5 behave horribly when importing Word files (as this one-and-a-half year old blog post proves: http://www.betalogue.com/2009/02/12/indesign-cs4-bugs/), and so I have a developed a habit of nail-biting-then-followed by importing troublesome Word files with CS3. Try that, if you have one lying around. It's easy: import into CS3, save, open that with CS4 (or CS5), done.
    If you don't have the older version, try to make it InDesign as easy as humanly possible. Open the document in Word, and:
    * Switch off Track Changes and Accept All that are still logged.
    * Search for images, first using the shortcut code "^g", and then by browsing (since Word -- heh heh heh -- cannot always find all of its own images!). Delete the images.
    * Remove all section breaks.
    * Save As an older Word version -- '97 might do the trick. Newer Word file formats suffer from feature bloat as much as any of Adobe's programs.
    With InDesign, don't import it into a document that's bursting at the seams with paragraph/character styles and master pages. Make a temporary new, blank document, and import into that. When you got it, you can safely copy-and-paste into the real target document.
    The number of pages ID can import at once has not been a problem for me, yet. I've successfully imported single Word docs that came in as a +1500 page document -- after applying formatting, 700 pages of real text remained. (At that point everything turned ..  a .. bit .. slowwww ... so I cut it up into separate files, after doing as much 'global' search-and-replaces as I could stand.)

  • Maximum size of an .air package

    hi forum,
    are there any limitations / recomendations for a maximum size
    of an .air package?
    i'm currently developing on an air application which will be
    distributed via cd/dvd. the app will have access to an fixed amount
    of image data (about 1,5 gb), i'm not shure whether its better to
    keep the data outside of the .air app installer an write an
    postroutinie which autmatically copies the data from cd to
    harddisk, or simply include the whole data whithin the .air file?
    last version would save a lot coding but i don't know if ther
    are limitations in the size of an .air packege

    Does anyone have any info on how to write a post-routine
    which automatically copies the data from cd to hard-disk?
    David
    hi david,
    thanx for your reply. think we have the same problem. here
    are my ideas to resolve this problem:
    1) writing a post-routine:
    as far as i know there is no standard post-routine function
    implemented in air. so we have to fake it. maybe this way:
    - create a prefereces.dat where you store all the application
    preferences (serialized data) in
    - create a "firstRun"-flag inside this file with the value of
    "false"
    - in the application init() method check this value
    - if set to "true" - run the application
    - if set to "false" call a "copyContent()" method
    - this method should prompt for a "toc.xml" (open a file
    dialog) which is stored on the cd
    - this toc.xml should keep all infos which content should be
    copied
    - now the user has to manualy go to the cd-drive an select
    the file. (you shoud check the file schema, whether its "your"
    provided file)
    - for later use- save the native path of the toc.xml in the
    flag "toc-path" inside the preferences.dat.
    - now copy all files (asynchronus) listed in the toc.xml
    (excluding the files in the "local-toc.xml", see below)
    - for "aborting proccess issues" you should also write a
    local empty "local-toc.xml" to the users hdd
    - for each copied file you should write an the associate
    entry from the cd's toc.xml to this local-toc.xml
    - this is important because if for some reasons the whole
    process fails (by user or system), we do not have to copy the whole
    stuff again
    - if all files ar copied correctly, set the firstRun flag to
    "false" - run the application
    - if not, exit the application
    - next time the app starts, it looks for the firtsRun flag
    again.
    - if its still set to "true" (cause the copy process wasnt
    successfull first time), the app matches the local-toc.xml with the
    toc.xml from the cd (read the path from the toc-path flag first, if
    not valid - do a new file dialog prompt)
    - now the "rest" of the content will be copieed
    - this procces loops till everything is well copied :+)
    2.) write a "real" installer
    - write a real installer with an installer build tool e.g.
    NSIS
    3.) hack air
    - try the new air wrapper tool
    "shu-player"
    - it wraps the air package in a single .exe
    - this a tool like mdm zinc for flash
    4.) hope
    - .... that adobe provides post-routines in the next release
    of air :+)
    well, hope this helps - this are just ideas which havent been
    realized.
    i'll keep you to date whether one solution works ...

  • What's the maximum size and length that go onto a DVD

    I'm trying to put a whole load of home videos onto DVDs. What is the maximum size that can be burnt onto a DVD. There are a lot of hours on here, about 15 and I was hoping to try and get about 3 hours per DVD is this possible?
    Thanks
    Tom

    If you're referring to a video DVD which will plan on a TV set via a DVD player then a single layer DVD disk can hold 120 minutes of playing time which includes the basic material and any animated menus in the project.
    A double layer disk can hold 240 minutes.
    If you are creating a data disk with the files copied to it then its a matter of grouping the files into batches of either slightly less than 4.7 GB for single layer and 9.4 GB for double layer.
    if you're referring to  video DVD discs follow this workflow to help assure the best qualty video DVD:
    Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image  menu option. This will separate the encoding process from the burn process.
    To check the encoding mount the disk image, launch DVD Player and play it.  If it plays OK with DVD Player the encoding is good.
    Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

  • What's the maximum size.......

    What's the maximum size of an ImageIcon to be supported by a Label???
    I'm trying to show a 3.5 Mb image and doesn't show it. But a 1 Mb does....
    Can anyone tell me why this happens???

    Well maybe you have to set the size of the Label to the size of the Image - use setPreferredSize() to set the size of the label....
    otherwise you can do something like this :
    //Get the Icon
    icon =
    new ImageIcon(YourFrame.class.getClassLoader().getResource(
                   "/images/yourImage"));
    //Get he Width of the Label on which the Image is placed
    int width = imageLabel.getSize().width;
    //Get the height of the label on which the Image is placed
    int height = imageLabel.getSize().height;
    //Get the Scaled image
    Image scaledImage = image.getScaledInstance(width,height,Image.SCALESMOOTH);
    //Set the Image of the Icon
    icon.setImage(scaledImage);
    //Update the Image Label
    imageLabel.updateUI();
    --j

    Hello,
    CM Repository in DB Mode:
    If there is a large number of write requests in your CM usage scenario, set up the CM repository in database mode. Since all documents are stored in the database, this avoids unintentional
    external manipulation of the data.
    CM Repository in FSDB Mode:
    In this mode, the file system is predominant. If files are removed from or added to the file system, the database is updated automatically.
    If you mainly have read requests, choose a mode in which content is stored in the file system. If this is the case, make sure that access to the relevant part of the file system is denied or
    restricted to other applications.
    What is the maximum size of the document that we can upload in a CM (DB) and CM (FSDB) without compromising the performance ?
    There are the following restrictions for the databases used:
    ·  Maximum number of resources (folders, documents) in a repository instance
       FSDB: No restriction (possibly limited by file system restrictions)
       DBFS and DB: 2,147,483,648
    ·  Maximum size of an individual resource:
       FSDB: No restriction (possibly limited by file system restrictions)
       DBFS: 8 exabytes (MS SQL Server 2000), 2 GB (Oracle)
       DB: 2 GB
    Maximum length of large property values (string type):2,147,583,647 byte
    What is the impact on the performance of Knowledge Management Platform and on Portal Platform when there are large number of documents that are in sizes somewhere from 100 MB to 500 MB or more.
    The performance of the KM and Portal platform is dependent on the type of activity the user is trying to perform. That is a heavy number of retrievals of the large documents stored in the repository for
    read/write mode decreases the performance of the patform. Searching and indexing in the documents will also take a propertionate amount of time.
    For details, please refer to,
    http://help.sap.com, Goto "KM Platform" and then,
    Knowledge Management Platform   > Administration Guide
    System Administration   > System Configuration
    Content Management Configuration   > Repositories and Repository
    Managers    > Internal Repositories   > CM Repository Manager
    Technically speaking the VM has a restriction according to plattform.  W2k is somewhere around 1,2G and Solaris, I believe, 4G.
    Say for instance I was on a W2k box I allotted 500+ for my J2EE Engine that would leave me with the possiblity to upload close to 600mb documents max.
    See if the attached documents (610134, 634689, 552522) can provide you some guidance for setting your VM to meet your needs.

  • Maximum size of XML files and number of IDocs for IDoc receiver adapter

    Hi Guys,
    We have an XML file to IDoc scenario where XI picks up an XML file with multiple Customer records in it, it does a simple mapping and creates one DEBMAS06 IDoc per record in the XML file. All IDocs are sent in a single file in XML-IDOC format to IDoc adapter which then posts the separate DEBMAS IDocs to R/3.
    a) What is the maximum size of XML files that XI can handle with mapping involved ?
    b) What is the maximum number of IDocs in a single file that the receiver IDoc adapter can handle ?
    The first time this interface runs almost 200,000 Customer records will be exported in one XML file.
    Thank you.

    Hi,
    Well it is difficult to find out the  maximum Size of xml messgaes that can be processed by XI and also Maximum number idocs an recevier Idoc adapter can handle.
    This totally depends on your production system loads and the limits can be set totally on trail & error basis..
    In my heavy loaded production system, i found out that the maximum size of the successfull messages after processing by XI is around 75 MB (seen in transaction SXMB_MONI). Whereas messages with size around 100 MB went into error.
    I havent encounter any such limits with respect to Idocs.
    I would suggest that you divide your data into smaller chunks and sent it part by part instead of sending it all once since you data size is huge.
    You can vary your batch size as per your system load.
    Regards,
    - Deepak.

  • Request: Ability to update metadata via spreadsheet view or csv file upload

    A fairly simple change to make Muse more efficient and user-friendly.
    I'm in the process of building out a medium size site for a client (90+ pages) - my first experience using Muse - and editing metadata is a pain. I've planned the site: page titles, descriptions, page names, etc, but updating metadata isn't the first step in my creation process and now I'm going back through updating information. My have a 2013 Mac Pro and 2013 Macbook Pro and both systems take time to update this information with so much data buffering and being updated.
    My request:
    The ability to update metadata across a site without the changes being executed until we applied the changes. For example, changing site view to a spreadsheet view with each pages information. Then, I could update a bunch of pages and hit enter, and walk away while it takes 5 minutes to update. This would also eliminate the hassle of requesting page properties from each page separately.
    Thanks in advance.

  • HttpSession maximum size

    Hello all,
    I was asked to research if HttpSession object has an inherited maximum size. I read the servlet spec (2.3) and there was nothing there about the maximum size of a session. Searched the forums and found some pointers but nothing concrete. I even saw a similar question with zero replies to it so if you think this is a silly or stupid question just say so. :)
    My presumption was that there is no set max size for the session object, that it depended of the capability of the server machine. Is there some vendor specific limitations (BEA vs. IBM vs. Tomcat vs. Sun) in implementation of the HttpSession interface? For one reason or other a member of my team thinks that there is some kind of limitation on the session size.
    Thanks in advance
    Dmitry

    A HttpSession has the same inheret limitations on its size as a ArrayList, a HasMap or any other Java object. Usually, the HttpSession is an ordinary Java object stored in some kind of Map global to the servlet-container. There is nothing special about it.
    General advice: dont store multiple attributes in a HttpSession. It is messy and unnecessary. Define a class that represents the state of a user session. Store one such object in each new HttpSession. Retrieve it when new request in the same sessions arrive and modify the session state object.
    As said: there is no special limitation on the size of such an object. I assume it speaks for itself that consuming large quantities of server memory for a single user is not a very wise thing.
