Tutorial project runs very very slow.

Hello,
I have just started to work with OAFramework and I am trying to execute the tutorial project. After configurating all my enviroment I am able to run properly this project with "Run > Run test_fwktutorial.jsp" but the problem is that it runs very very slow. It takes at least 5 minutes to load the "Hello World!" and the same time to load the other pages.
We work with Patch Jdeveloper 5455514 and our system is Oracle Applications 11.5.10 RUP4.
We are connected to our system via a VPN client. Could it be the reason for this poor performance or are there other things I shoud have to modify?
Thanks in advanced,
Xavier

Hi Xavier,
There can be multiple reasons why the Jdeveloper is very slow. VPN might be one of them. Try accessing the Oracle Applications using the VPN connectivity and observe the speed. Try to do some transaction and notice whether database is slow or not. You can also double click the jpx file and check for the db connectivity by clicking on 'Test Connection' and see how much time it takes. The other reasons why the Jdeveloper is slow might be because you have multiple projects opened. You can also try to close the Jdeveloper session and restart again by deleting the myclasses and systems folder.
See whether one of these approaches help.
Thanks

  • Make project run smoother

    Hello all,
    A general question on a finished project. I'm using Captivate 5 on an "average" PC running XP.
    I have a project of around 90 slides, most with audio but with simple animations. Pictures fade in and out and some instructions on how to use a system in general. Nothing advanced so to speak.
    I feel the project runs a bit slow when I have published it and click through it. When I click a button it takes a while for it to jump to the disired slide and so on.
    I set the preloader to 100% and also added a "loading-slide", that doesn't do anything, in the beginning of the project to let it set.
    Any ideas on how I can make it run better?
    Thanks in advance.
    Kind regards,
    Patrik

    Thanks for the replies.
    On the "home screen" of the presentation which is also the first slide, you have a lot of different options on what you would like to click on, so it's more branching than linnear.
    One thing I noticed is that the option in the top left corner, which most people are probably gonna click first is in the very end of the project in Captivate. So you reckon it would flow better if I perhaps moved that to the first couple of slides in Captivate?
    I'm mosty using "jump to slide", is that an issue as well?
    The project has a coupel of text animations, but mostly png.-files fading in and out.
    Thanks for the help.
    Kind regards

  • My macbook pro is running very slow and very very hot

    hi everyone I have a 13 inch mid 2012 MacBook pro,
    it is running very very slow and extremely hot, I downloaded a program called smc fan control and it is reading the internal temperature of my computer as 80 degrees Celsius. I was looking on the forums and saw that I should run an apple hardware test. which I have done and it is coming up with Error 4/MOT/4/40000002: EXHAUST-2003
    what does this mean? is it something to do with my fan?
    also there is a very strange clicking noise when I lift the mac up or if its on its side and sometimes it just randomly freezes,  the computer does not respond and then it restarts.
    what do I do?
    please help!

    " the fan didn't seem congested with dust, at least not enough to cause any malfunction."
    The lint and crap builds up in the heat exchanger radiator. It's the grilled thing at the output of the fan.
    https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Unibody+Mid+2012+Fan+Replacemen t/10367
    Look at step 6. It's that grilled thing at the top of the fan. If you remove the fan that radiator is probably clogged with lint. Brush it all away and if possible blow out the fan with compressed air. Make sure the fan turns freely and doesn't feel stiff.

    This isn't a MBP radiator but the problem will look like this.

  • Reasons why CS6 is running very very slow?

    I have InDesign CS6 and the program is running extremely slow. I have googled and tried all troublshooting options but still cannot even highlight a sentence without it taking 30 seconds. Just going from one document to the next takes a very very long time. Besides for turning preflight off and other tricks is there anything else I can do to fix this problem?

    Are you working documents from an older version of Indesign? I found that even though the document is "converted" Indesign CC has major problems with any older version's files.
    I had to convert all my old files by copying masters and pages to a new, blank indesign cc document. All the speed issues went away.
    Unfortunately, even though you can open the file, I don't feel it's compatible because you can't really work at that speed and still be profitable.
    But hope that helps...

  • I am using ipod touch 4g 8 gb, with ios6 software. It is getting very very slow even after i reinstalled the software. Apps like temple run 2 and subway surfers are getting stuck and it is very very slow.My ipod has 2.6 gb free space.

    I am using ipod touch 4g 8 gb, with ios6 software. It is getting very very slow even after i reinstalled the software. Apps like temple run 2 and subway surfers are getting stuck and it is very very slow.My ipod has 2.6 gb free space. What is the problem. I am not getting to know. Even after i reinstalled these apps it is still getting stuck and it is very very slow. Is this what i get after paying so much money for ipod. Is this what i get very poor perfomance.

    Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
    Next
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup. See:                                                
    iOS: How to back up                                                                                     
    - Restore to factory settings/new iOS device.

    Re: Mail under Mountain Lion is painfully slow / unusable

    Finally - I have a fix. It was related to address book problems.
    The solution is highlighted here:
         https://discussions.apple.com/message/19037910#19037910
    *** Be warned though - make sure you already have contacts up in iCloud before doing this:
    1. Bring up System Preferences, go to iCloud and uncheck "Contacts"
    2. You need to remove the folder /Users/<your_name>/Library/Application Support/AddressBook
    If you have issues removing, quit Mail and Contacts
    If you don't have contacts in iCloud, try renaming the folder
    3. Reboot the machine
    4. Bring up System Preferences, go to iCloud and now check "Contacts"
    Now when you bring up Contacts, it should sync with iCloud, Mail and Messages will work fine.

  • W/ this latest version, getting MANY "the connection was reset" pages, plus VERY VERY VERY slow loading. I'm running Windows 7 on a new Dell. What is up w/ that?

    w/ this latest version, getting MANY "the connection was reset" pages, plus VERY VERY VERY slow loading. I'm running Windows 7 on a new Dell. What is up w/ that?
    I don't know how else to phrase that. I'm a pretty good user, but after defragging, backing up, and getting rid of a bunch of files that "may" slow down performance of firefox, the fact is, "the connection was reset" comes up five or six times a day--AND the browser is going slow as molasses. I haven't had this much trouble since before I got my new dell.

    hello whatagem123, it is never a good idea to stick with outdated versions of firefox just for the sake of addons, as this will put the integrity of your system and your the personal data on it at risk - there are various [https://www.mozilla.org/security/known-vulnerabilities/firefox.html known security vulnerabilities (some of them highly critical)] that were fixed in later versions!
    so please [[Update Firefox to the latest version]] & [https://www.mozilla.org/en-US/plugincheck/ update your plugins] (your java plugin has security vulnerabilities that are actively and widely exploited on the web).
    afterwards i'd recommend resetting firefox - this will keep your bookmarks and passwords but will get rid of most other customizations. this might well fix both the issues you've described in your question...
    [[Reset Firefox – easily fix most problems]]

  • T500 running very very slow on specific WIFI network only???

    Hi,
    This problem is driving me absolutely crazy. It means that I can only use my PC at home if I use a cable connection to the router....
    Problem is that on my home network my T500 is having a very very slow access to the internet via wireless. On all other wifi network I have connected to there is no issue and speed is high.
    Also several colleagues have been here with their T500 and none of them experience any issues with speed. We all run on the same t500 model, ordered at the same time and with same setup. We use Windows XP.
    I have tried to update all drivers, I have called my network provider who have updated router software, changed frequency and all other things they could do to avoid interference etc.
    I have two other PC's at home - none of them have any issues.
    I have done a web seacrh and could see that I am far from alone with this strange issue of a T500 being slow on only a specific network (often a home network). Many different routers are involved, so I dont think it is  arouter problem (would also mean that my colleagues identical t500s would have issues right??).
    Have there been any reolution to this T500 problem??
    Best regards and with hope of "salvation" :-)

  • Large Premiere Pro CS6 Project running very slowly

    Hi there folks. I'm about to ask a question to which I'm fairly certain the answer is "You need to upgrade your RAM and Video Card." But I thought I'd toss the question out to Adobeland just for the slightest, minesculest chance there might be a software fix.
    Basically, I have a huge project for this promo. About 4TB worth of footage all in all. Almost all of it is PRORES 4444 from an Alexa (which runs like a charm) but there's also a great deal of full hd XDCAM transcodes of several of a networks full feature films (They're about 80GB each).
    These films are killing my project. I can't even watch them for more than a few seconds without Premiere just stalling out, that's fine, I can cope with that. But apparently just having them in the project is enough to slow the whole thing down even when I'm only using a few clips on my 60" timeline. It takes 45 minutes for the project to fully load up, and I'm constantly clearing the cache.
    I'm running a Mac Pro (Mid 2010) 2 x 2.4Ghz Quad-core Intel Xeon, 12 GB 1066 Mhz DDR3, ATI Radeon HD 5770 1024MB using OSX Lion 10.7.5....
    If there's any little software tweaks or fixes that can speed up Premiere.
    PS - I've tried using project manager to create a new trimmed project with handles, but for some reason this never works for me. It just makes copies of the entire original clips without trimming them. I've also tried transcoding the Larger files to smaller versions, but this process is taking way too long and keeps crashing
    Any advice would be greatly appreciated.
    Much Love
    Martin

    In After Effects you 'purge' the cache to free up RAM, in order to preview other compositions. In Premiere, it is a bit different, because this program works with different cache files and different ways of storing them. There are files used for previews/renders, created by the user - and files for caching information about media used in the project (metadata, waveforms etc.), created by Premiere. The only ones you can delete are the render files, found in Adobe Premiere Pro Preview Files (if you don't need them at one point; they can be easily recreated by rendering again). All the others (the ones you say that you delete through 'Preferences') need to be kept, because Premiere works with them. I assume this is the reason it takes that long when opening the project, because Premiere needs to re-cache everytime. Don't delete them and see how it goes.
    Just as a reference point for you: I have a powerful computer (dual Xeon, dual nVidia, 64GB RAM), and I still have to decrease the playback quality sometimes to 1/2. The lowest I can go is 1/4, and I assume your Premiere allows decreasing at least to 1/8, with the rest of values grayed/unselectable.
    I think you need a better graphic card first, one that is accepted by Premiere, for its CUDA capabilities. Check their website, I think your Radeon is not allowing the use of Mercury Playback.
    Best,
    Mark

  • InDesign CC 2014 is very very slow when working with a table.

    InDesign CC 2014 is very very slow when working with a table. Every 1/2 - 1 hour it nearly falls back, impossible to work with. While this project must be finshed quite soon..
    What the hell is the matter with this Creative Cloud. I havea very fast iMac form 2014. I closed all other programmes, even cannot listen to music now. More people with this problem??

    @Martien – How complex is your table?
    How many cells? Merged ones as well?
    Complex formatting of texts inside the cells?
    Complex formatting rules of table rows and/or columns?
    Many images inserted?
    If yes, and the table is running through many text frames of many pages, I fear, you can do nothing against slowness.
    Nothing but: Greek text, not showing the page contents in the Pages Panel, in short: anything you can do to get better performance in redrawing of the screen.
    If you have the chance to break up one big table in several parts, do that and edit its parts one after another isolated. Pehaps in different documents.
    Then merge the parts in one table, if you want to flow it from page to page.

  • Qemu with kvm is very, very slow

    Hi!
    I first installed kvm by following http://wiki.archlinux.org/index.php/Kvm
    And I also tried the "using qemu with kvm support" method from http://wiki.archlinux.org/index.php/QEMU
    With both methods, a VM is very, very slow (when i start an iso, you literally see it render the things, and after that when you get the grub menu, it takes ages for the pointer to move if you press the arrow keys).
    I'm on a Dell laptop with Intel C2D cpu with VT support (and enabled in bios, I checked)
    [dieter@dieter-dellD620-arch ~]$ egrep '^flags.*(vmx|svm)|model name' /proc/cpuinfo

    anyone an idea?

    try qemu-kvm-0.10.5, it's the stable qemu with additional kvm support:
    http://sourceforge.net/projects/kvm/fil … z/download
    also, in the qemu monitor you can check to see if kvm is used with "info kvm" .. should return "kvm support: enabled"
    finally, the grub menu is using old BIOS APIs and cpu pooling since it's running in 16bit mode with no drivers. It uses up 100% of one of my cores when I leave a VM on the grub menu. Make sure you run a serious OS soon and check performance there.
    Thanks
    - i am using 0.10.5 (this is the version that Arch has packaged)
    - it says kvm enabled, and you're right, once it goes out of grub, it goes much faster!
    - apparently my keyboard arrows are just plainly being ignored

    Hi,
    the plan isn't showing any problem (the cost isn't high) so it's not possible to use it to troublehshoot the query. Please provide more information: 4-digit Oracle version, and depending on the version, either SQL real-time monitor report or dbms_xplan output with rowsource stats (option "iostats last" after running your sql with ALTER SESSION SET STATISTICS_LEVEL = ALL).
    Also, when reporting a performance problem it would be wise to avoid expressions like "very, very slow" replacing them with something more useful like "my query is taking 2.5 hours to retrieve 30k rows".
    Best regards,
    Nikolay
