Too much request URI when send long MapViewer application via utl.http.request

Hi all

I am creating a website where users can select layers by using the checkboxes and then showed the layers resulting.

However, when users select a number of layers I get the error message:
Request-URI Too Large
The requested URL's length exceeds the capacity limit for this server.
request failed: URI too long
After testing this out in v3 of Firefox and Internet Explorer v6, I get the same error message in both. After reading some other threads here I know that the problem is due to the url is too long. I can't shorten the url and there's a chance that the layers more added to the database where the layers are stroed, he could become even greater in the future.

Therefore, no one knows how a XML request may be sent to MapViewer using HTML, without the use of URL. While the url is not displayed on the screen, it is sent to utl_http.request. I don't know a form would work for sending a request or if it would be, how it could be implemented using utl_http.request or any other utl.http method.

I use MapViewer 10.2 and Oracle 10.2.0.2 and I'm not able to upgrade if it was no longer useful.

Kind regards

Tim

Tim,

I do not understand your architecture - specifically how the UTL_HTTP package comes into play here. You send your XML request from the browser to the base, which will then forward to Mapviewer via the UTL_HTTP package? Or you send them directly from the browser, in which case UTL_HTTP plays no role in the picture?

To send a mapviewer request using the POST method, via a form, here's how the form would look like in simple HTML:


I did a few tests. Using the POST method, I observe no restriction: the xml query can be very large: I did tests with 16K applications and more. Using the GET method, I get chess (HTTP 400 Bad request) as soon as the resulting URL will more than 4 KB.

  • Using too much CPU only when loading the network

    When FF works closely with the network (wired or wireless) card for access to the network, CPU utilization spikes in way more than 70% and he stayed there until the page loading process finishes web.
    After the upload is complete, the CPU usage remains somewhere between 5-10%.

    When I look at clips youtube 1080 p, where FF is duty next buffer part of this clip I watch, new CPU use peaks above 70% with the flash plugin and gives a total of a 100% of cpu for a few moments and use which make this clip to stop playing or to frame bad times, and ties.

    I have been activated in about: config webgl acceleration to activate the force and that much improve the initial problem, then I activated gfx.direct2D - activated force and also to improve the problem remaining.
    I also disable the safe_mode parameter file adobe flash config protectedmode = 0.

    I have to mention that the initial problem was way to bad ... 
    

    Now I get to point when I don't know what to do so that FF does not use much CPU loading pages.
    As you can see I use to publish this version of Nightly 64 bit (I think it's the 64-bit version...) which is much more better and I would like to read youtube 1080 p clip normally, after that I have wait a few moments to buffer, before starting to play.
    Version 32 bit FF won't let me watch YouTube without framing hurt when the clip is buffered.

    I was monitoring the Task Manager and all the processes listed... and there, I can't blame antivirus or firewall to the peaks of the processor. Also if I do the rest of the network traffic, as well as inside the network custom CPU even file copy flinch.

    Can someone help or give an opinion on what setting to do, so I can eliminate these spikes?

    Thanks in advance!

    Problem solved partially:

    I have observed that the CPU spikes occur not only while I use FF or mozilla nightly, but on all web browsers (Chrome, IE, Opera, etc) that I have used, while these browsers accessing the network.

    Uninstalling the firewall of the solution of the AV portion has helped a lot and by also disabling the bed in the firewall solution of W7, but for long term use, this isn't the right answer (for my at least). Without any firewall FF work or installed works like a charm, while the CPU usage is increased at a decent level of 50% max (total tasks and running services)!

    Anyway, as I said earlier, my pc without any firewall operation is not a good think to do, so I'll replace my computer with a faster, or I'm going to overclock it at a level that zapping INTERNET and navigation will not infringe too much on the performance of the system, or... I live whit it and I accept the limitations...

    Perhaps, in the development of the FF, programmers will keep in mind that not everyone on this planet has powerful processors - and... give a few options... to decrease the CPU at acceptable levels, event, even if they use the firewall solutions that violate on the CPU while FF is buffering of data across the network.

    I should also mention that Mozilla nightly (64-bit) and FF, are always better then IE - in my opinion - which is.

  • Uncaught exception handler application when you install the application via the Desktop Manager

    Hello

    I sometimes have a problem when I install my application on the new phones (mainly with OS6 and OS7) using the Desktop Manager. When installing the application net_rim_bb_trust_application_manager raises an uncaught exception as if had been stalled and its eventqueue was too long. The application itself is installed and works perfectly after a battery pull.

    The question is a bit like the problem described in this thread:

    http://supportforums.BlackBerry.com/T5/Java-development/Autostart-on-installation/m-p/471949#M94686

    The problem is that the solution mentioned here does not solve my problem. My request to have multiple entry points and one of them is an autostart entry point but she must leave the application, unless a parameter in the application autostart enabled (which is not the default). I don't see how this should pose problems for the application manager.

    It is also worth mentioning that this happends only when the application is installed the first time on a new device or a new version of the application that is signed with a different code signing key is installed on the device. The problem will not occur if the application is uninstalled and then installed again. This makes me think that it's something with the permissions to a...?

    Someone at - it had the same problem and solved it?

    Here are the 'new' version of this same article:

    http://supportforums.BlackBerry.com/T5/Java-development/write-safe-initialization-code/Ta-p/444795

    Not sure this is the same problem however, because the user described the problem as being present during the installation, date at which the device is fully functional.

    I agree that it is likely to be a permissions issue.  I saw on some devices that the app will throw a ControlledAcessException on first installation, associated with the PersistentStore.  My suspicion is that there is a kind of race condition between the code that runs the auto-start and the code that is supply completely, for the first time the auto start run on installation, the device is not ready for it.  I thought a few seconds delay automatic start of treatment of coding, but never tested it.

  • When sending long E-mail, top bar containing the Send button will view, how to send in this situation?

    During long typing NEW e-mail, the text develops the window moves to the top and the button SEND disappears under a different toolbar at the top of the screen. How can I send an e-mail when the SEND button is not accessible? I can't pull the window and send button area down enough to allow the cursor to activate.

    There are different ways to do... The simplest is to click with the right button on the element (I think you said a toolbar at the top of the screen) which covers the button send, select 'Inspect element' or press 'Q', then click on the arrow down next to the element name and choosing 'Remove the node', then the toolbar disappeared , and you may see the submit now button.

    Hello! I was wondering if there is a signal that is sent when opening an application through the overview of the App:

    What I mean is: I develop an application, where you can insert data through the invocation. These data are not displayed, when im back to my application with the preview of the App. Is there a way I could load a function "reload" (that I create myself of course) when the user opens my app with this overview of the app?

    each type of help is very appreciated!

    Hello

    Are you seriously having over 500 DEFINITIONS of FIELD Application of IPM? If so,.

    What you can do

    In the config.cfg to UCM (DomainHome/ucm/cs/config folder) can you add this in the general section:

    IpmMaxMetadataFields = 1000 (or any number you want to increase the)

    limit to)

    This will overrride the default max value in IPM.

    After this change, restart the managed server UCM and IPM.

    Please let me know the result.

  • QlikView Thinapp start Office installation / repair of routine when sending data to Excel

    Hello

    I have a Thinapp of Qlikview 11/11.2 built with VMware Thinapp 4.7 race. The ThinApp is the installation of MS Office / repair of routine when sending data to Excel via the option "sent to Excel".

    Excel is started, the data sent are displayed, but after a few seconds the installation / repair turns on.

    When the Setup routine asks you to restart the license error message is also coming:

    "Microsoft Office is unable to verify the license for this application. An attempt of repair failed or was canceled by the user. The application will now be stopped. »

    [Compiler options]

    AllowExternalKernelModeServices = 1

    AllowExternalProcessModifications = 1

    VirtualizeExternalOutOfProcessCOM = 0

    Native MS Office installation is permitted via KMS and there is no defective behavior when Excel is started directly or through associated files.

    My goal now is to avoid the opening of installation / repair of routine and the license error.

    Any help is appreciated!

    Get rid of the changes to the package.inj you have already done and add them instead:

    In package.ini:

    VirtualizeExternalOutOfProcessCOM = 0

    ChildProcessEnvironmentExceptions = WINWORD. EXE; EXCEL. EXE; POWERPNT. EXE, OUTLOOK. EXE; MOC. EXE

    ChildProcessEnvironmentDefault = virtual

    This will make sure excel is not running in the virtual environment of your parcel.

    My problems are:

    1. Microsoft PowerPoint, Word, Excel take a long time to get on my screen.

    2. I also get the message that I ran out of memory for the application.

    3. I have to restart my computer in other applications, because I get the color wheel.

    4. I thought I erased everything related with Norton, but I always get a reminder to renew whenever I start.

    I hope that's not too much, but I appreciate your comments.

    Thank you

    2. I also get the message that I ran out of memory for the application.

    Maybe it's the origin of many of your problems.

    There could be 2 causes.

    (1) your startup disk is out of space, and OS X can create is more / var/vm/swapfile (s)

    (2) the collection of processes that are running on your system has requested more virtual memory that OS X is ready to handle.  This happens usually when there is a leak of memory in a program.

    You should start with Applications-> Utilities-> Activity Monitor and watch your memory usage.  I hope over time, you will notice that one of the applications consume much more memory than anything else.

    When your system is starting to exhibit slow performance, but it is still able to do something, run EtreCheck and then after the release in response to this forum.  It is important that you expect from your system approaches of the State where it is either going to give the out of memory performance or the application only allows you to run anything.  If you post the production of EtreCheck of a freshly booted system, it will be not as useful as the system in trouble.

    https://discussions.Apple.com/docs/doc-6174>

    You can conduct an experiment by starting in safe mode

    http://support.Apple.com/kb/ht1564>

    Safe mode does not load 3 additions of party, so if they are the problem, you will not see the same performance issues.  HOWEVER, safe mode loads some much more conservative drivers, and the Mac cannot perform fast and have a few flickering screen.  But if you can live with that period of time where a system booted normally would start to misbehave, safe mode could give you an indication that it is 3rd party additions.

    In addition, EtreCheck will show 3rd party additions, including any residual Norton Utilities that hang around.

    The forum long term contributors is discouraged unnecessary utilities unnecessary anti-virus Mac apps cleaner and useless apps expanding.  It has been our experience that all contribute to the performance of OS X problems and in some cases of the core OS X gets crazy.

    Another thing you can do is watch the Applications-> Utilities-> Console app for frequent of the journal entries, as a process that starts, dies, starts, dies, starts, dies, wash, rinse, repeat.  A dying like that process can consume a lot of resources, but do not appear in the activity monitor, neither an EtreCheck report.
