JDeveloper performance unacceptable

Hi,
I am using JDeveloper 10.1.3.2.0 on Windows XP (SP2).
It runs on a laptop with a 1.8 GHz CPU and 2 Gb of memory.
Apart from JDeveloper, I am only running Firefox and MS Outlook.
The performance of JDeveloper is absolutely unacceptable.
JDeveloper is not responding to my keyboard.
When I enter some text in the editor, the cursor stops blinking and the screen is not getting updated for several seconds.
I am working on a rather small Java application, the total size of all files is less than 1 megabyte. I am not running any databases or OC4J.
According to the Windows Task Manager, JDeveloper is using 50 Mb of memory, and 419 Mb of virtual memory.
Of the 2Gb of RAM in my pc, 910 Mb are still available.
Why is JDeveloper using so much virtual memory when there is plenty of RAM in my machine?
Thanks in advance,
Marcel.

I never saw this unless I was doing a lot of different stuff like running an application on my embedded OC4J or something like that.
You might want to try to run jdev.exe instead of jdevw.exe. That will give you a console in which JDeveoper will show extra information, like for example an out of memory error, exceptions and so on.

  • JDeveloper performance with XSL Mapper

    Hi All,
    Not sure if this is the right place to ask this question since it has to do JDeveloper performance with SOA and not ADF.
    In the XSL Transformation mapper tool, whenever I do an auto-map between two large schemas, my JDeveloper memory usage hikes up to about 1.3 GB and then both the JRE and JDeveloper hangs although the transformation finishes. The problem is that sometimes it hangs before you can save it. It almost seems like a memory leak.
    NOTE: I am not getting any out-of-memory error since I increased already increased the memory.
    Any help to optimize and solve this problem will be very helpful.
    Thanks!

    chk this
    http://docs.oracle.com/cd/E11036_01/doc.1013/e10295/xslt_mpr.htm
    you should have SOA composite application extension for this..
    if you dont want a visual transformation then you can use the jdeveloper project properties -> Run/Debug -> edit run configuration -> XSLT

  • JDeveloper performance

    I recently downloaded JDeveloper Studio 10.1.3 and what I am finding is that it is really slow. This is on a Dell laptop, XP Pro SP2 with an Intel Core Duo processor and 1GB RAM that is only a couple of months old, it is a quick machine. I have Oracle 10g R2 installed along with Apex 2.2 and Developer Suite 10g R2 and all of those run just fine. But JDeveloper is just so slow as to be almost unusable. I'm talking 2 or 3 seconds to respond to a keystroke in the editor, or 5 or 6 seconds to repaint the screen after being minimised or switching between tabs. Has anybody else noticed this or is there something I can do to make it run a bit faster? Is 1GB RAM considered sufficient? Even with JDeveloper open and the database running Windows Task Manager reports at least 150MB physical RAM being free.
    I'm also sure that the machine is virus and malware free.
    Any suggestions welcomed because it is driving me nuts!
    Regards,
    Steve

    The thing that fixed it for me was uncommenting the line in the jdev/bin/jdev.conf file with this on it:
    AddVMOption -Dsun.java2d.noddraw=true
    All the rest of the tweaks on the various blogs mentioned in this and other posts on the subject didn't change the performance at all.
    Oddly, enough, the issue is described in the jdev.conf file. Considering that this is a Windows option in a Windows distribution it's surprising that the sun.java2d.noddraw=true option isn't set in the first place.

  • [BUG] JDeveloper performance bug

    Hi,
    I am working on ADF faces and hit a performance bug:
    When displaying the "design view" of a jsf page, Jdeveloper hangs for more than 15 minutes (thats why it is a bug, not a simple issue), then it displays it correctly.
    Host is a P4 3Ghz with 2GB RAM.
    Configuration:
    ADF Business Components     10.1.3.36.73

    Hi,
    just a suggestion... Please control whether you run another process in background. In windows op. sys. look at task manager and control processer usage and memory usage!? is there any weird resource consuming!? Also control your disk fragmentation!? Is your hard disk fragmented too much!?
    Also, in the beginning, my designer in jdeveloper was not shown because of my locale setting. My locale setting was Turkish (tr) and user interface designer didn't show the user interface components during page design. After I changed locale to en_us, the designer shows the user interface designer properly. just check it!
    I couldn't help any more according to your feed back :-)
    best regards...

  • Jdeveloper performance issue

    Jdeveloper 11.1.1.6
    I observe that Jdev is very slow & hangs often, though I am having 8 GB RAM in my PC. Found certain articles in the web to improve Jdev performance & made the following changes in the Jdev configuration files:
    $JDEV_HOME/jdeveloper/jdev/bin/jdev.conf
    #AddVMOption -XX:MaxPermSize=256M
    AddVMOption -XX:MaxPermSize=1024M
    AddVMOption -DMainWindow.MemoryMonitorOn=true
    $JDEV_HOME/jdeveloper/ide/bin/ide.conf
    #AddVMOption -Xmx640M
    #AddVMOption -Xms128M
    AddVMOption -Xmx640M
    AddVMOption -Xms640M
    After making the above changes (rows prefixed with # are the original values; getting virtual memory issue if these values are increased more than these), I observed only marginal improvement.
    Any thing else to be done to improve Jdev 11.1.1.6 performance?

    Hi Timo,
    I work on a PC with Windows 7 64 bit OS. Java version details given below:
    java version "1.7.0_15"
    Java(TM) SE Runtime Environment (build 1.7.0_15-b03)
    Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
    I do have an anti-virus software, but I don't see a problem there as my other applications work smoothly.
    My jdev hangs mostly when I drag & drop a data control into my form. Other operations like drag & drop within the structure, switching to XML source, typing in XML source etc. are slow.
    While running Jdev, I have my outlook, pl/sql developer & the browser windows. I checked in task manager. Hardly 70-75% memory is occupied.

  • JDEVELOPER PERFORMANCE PROBLEM

    Hello All,
    Jdeveloper 9i with OA extension is very slow in my machine.Im running with 512MB ram and the database is remote. The browser is waiting for a long time when JDeveloper shows the following message
    Tutalii: D:\Jdev9iOA\jdevbin\jdev\appslibrt\iasjoc.zip archive
    what may be the problem.
    Thanks,
    Kannan

    Thanks for your reply,
    When accessing server side objects (like table,view etc) there is some delay but its not that much longer. So from your query can i guess this, if the server is slow then it will afftect the performance of jdeveloer. If it is can we do anything on this.
    Thanks,
    Kannan.

  • Jdeveloper performing one time indexing

    I have successfully installed Jdeveloper 9.0.4 on Windows 2000 OS; after i have opened the IDE and i have created my first project in a new Workspace the system become very slowly because Jdeveloper is "Performing one time indexing of file....".
    What does it mean?
    How can I stop this process?
    How can I start this process manually (for example when i stop working....)?
    Thanks!
    Leonardo

    I find it really impossible to believe the amount of RAM which JDeveloper consumes. Even after feeding it with 512 MB RAM for which i had to go for a motherboard change (my older board only supported 256 max) and changing the processor to 1.8 Ghz Pentium my system is slow when Jdeveloper is running.
    Now if i have to run the oracle database server and an application server like websphere, i guess even a supercomputer would give up.
    Just as a side-remark Visual studio.NET architect along with SQL server and IIS runs good in 128 MB ram and in 256 MB it flies
    My apologies for hurt sentiments, if any

  • Unacceptable Performance - Unacceptable Point Patch Policy

    There are known issues with Flash CS3. Notable of these are
    the publish crashes on all platforms. I find it completely
    unacceptable that Macromedia > Adobe's perspective on patches is
    typically 'a paid upgrade will patch the program'.
    This is completely unusual in the industry and the fact that
    you now hold the monopoly on good (great tools, but not perfect
    tools) is no excuse for not fixing issues with your software. I
    find it pretty deplorable that you will fix known issues by
    pitching an upgrade. 'Pay to upgrade or live with the issues' is no
    way to be.
    Flash crashes on me no less than 10 times a day. Most of
    these crashes occur at publish time. I save my work often, but even
    a 15 minute loss is aggrevating. When Flash locks or crashes,
    windows can lock things like the context menu from use - this
    requires a restart. So a Flash crash ends up doing these things:
    1. Interruption of flow
    2. Loss of work
    3. Loss of time
    This can equate to a momentum loss, time loss, and work loss
    of up to an hour. Multiply this by 4 to 10 times a day and you can
    only imagine how steamed a developer can get.
    I use Vista, but I understand that this issue also occurs on
    Mac. I use video editing software, word processing software,
    spreadsheets, and other authoring software that doesn't crash. Why
    am I expected to live with this until Adobe releases a full point
    release?
    Can I get an amen from any other developers out there? I'd
    love Adobe to be as responsive to developers (IDE users, I've seen
    a lot of catering to the more hardcore programmer types that tend
    NOT to use the IDE anyway). as they are to the public with Flash
    player updates.

    You realize, of course, that the "you" referred to in your
    post is not Adobe. This is a user-to-user forum. If you're unhappy
    with Adobe policy, write to them directly. The likelihood of anyone
    from Adobe with any influence reading this forum or this post is
    next to null.
    That said, as a Flash user since 2000, I'm flabbergasted at
    the attitude that Flash is somehow "perfect" upon release and no
    bugs exist. I was hoping this policy would change when Adobe bought
    Macromedia, since Adobe tends to release a few patches for each of
    its major apps as bugs are uncovered.
    But alas, no hope. I once cornered one of the leaders of the
    Flash development team at an official Macromedia event a couple
    years ago and brought this up. He replied that they "need to focus
    all their resources on developing the next release." I had to
    withhold myself from being really rude in response.

  • Jdeveloper performance issues on Core 2 Quad PC

    Hello,
    I'm fairly new to the forums, I've read a lot but never posted anything, well, on to the problem.
    At work my company uses Jdeveloper, I'm on a low Pentium Dual Core @ 2.66Ghz, and 2GB of ram, not the best computer but it does the job.
    I recently installed the latest version of Jdeveloper at my personal computer (at home) which is a Core 2 Quad @ 2.4Ghz, 4GB ram, Nvidia 8800GT 512MB.... It's a good computer and Jdeveloper is a lot slower on my personal computer than on my work's computer.
    I've noticed that Jdeveloper uses both cores at work, but only 1 out of 4 at my home's computer, anyone know what seems to be the problem here? why isn't it seeing the rest of the cores? I checked the jdev.conf settings and the 1 core thing isn't on, it should see all 4, any ideas?
    Help would be greatly appreciated. Thanks in advance for your replies.

    Hello Frank,
    I've had this computer since December, and every program either uses 2 Cores or all 4, I've read about certain programs not able to identify a Quad core as such and only use 1 core.
    None of my programs does this... except for Jdeveloper and it's irritating that even programs I don't need or like can use several cores and Jdev (the one I actually need to go fast) doesn't seem to be able to recognize the processor or something...
    Anyone have any experience on this?
    Thanks in advance for your replies.

  • CATS: From ITS (CATW) to Web Dynpro, performance unacceptable

    Hello all,
    we just changed the R/3 from 4.7 to ERP6. Within that change of release we should have changed the CATS-UI in the portal too.
    Formerly we had the external ITS using service CATW. That solution is no longer supported by SAP for ERP6. So we imported the new Business Package for ESS containing the working time application, setup the SLD, JCO connections and all the relating stuff. We made an end user test and ran into a performance disaster.
    Using a normal Client PC (around 1 GB RAM, between 1.9 and 3.GHz CPU, Windows XP, IE6) it is not possible to work in an acceptable mode.
    There are mainly two issues. First the speed at all is out of question. Secondly, when a user clicks on a time cell, he cannot directly write something into it, the application first has two mark that cell for itsself, it flickers two times (slowly...slowly...) and then is ready for input.
    We cannot offer such an application to our users.
    We had no choice and had to reanimate the service CATW via the internal ITS, but as it is not supported we are left out in the rain when facing problems.
    Does anybody have similar experience ? Is there a way to speed up that application into an acceptable response-time-range ? As we are also using other Web Dynpro applications (e.g. leave request), that are not that slow, there is a slight hope that the reason lies in this specific application and there perhaps is a workaround.
    Thank You !

    Hello Andreas,
    I know this is a very old thread but you might still help me.  We are migrating from R34.7 to ECC6 and we also have a problem because we customized the CATW ITS application so badly that it will be nearly impossible to implement theses changes in the new ESS based CATS.
    We thought that we could keep for some time the old ITS but according to SAP note 709038: "the SAP ITS 6.20 cannot be used to connect to system based on SAP NetWeaver 2004s".
    However it seems that you managed to do so (ITS 6.20 - SAP NetWeaver 2004s), can you confirm ?
    Best,
    Julien

  • Performance unacceptable after installing lion on late 2007 MacBook Pro

    I have a mid-2007 MacBook Pro with 2Gb of memory and a 2.4GHz Intel Core2Duo.  Since installing Lion, Safari is all but unusable, it takes forever to load, every page I try to load stops the entire computer with the spinning beach ball, I haven't even tried flash sites. iTunes hangs every time I download a podcast at the processing file stage.  I keep iTunes open to feed my AppleTV, but after a few hours of watching I have to restart iTunes because everything starts to hang.  To say nothing of what happens when iTunes starts automatically downloading podcasts.  Syncs with my iPad have been hit or miss.  The entire machine seems slow and sluggish.  I tried running one app at a time, and that helped some, but it didn't fix the problem.  I am assuming this is a RAM issue and have ordered more, but Apple said it would work with 2Gb of RAM.  I don't call this working.
    So my question is does it save memory to run apps in full screen or should I keep them as just windows?  I have tried to kill all the extras, and I have been trying to just do one thing at a time, but I have honestly never had this kind of reaction to a new OS when the machine was in spec.  And I have been upgrading since system 7.  Is 4Gb going to be enough?  Is the processor just not fast enough to handle it?  Upgrading to a new machine is not an option at all, and I really like the working bits of Lion I have seen, but am I stuck?

    I haven't done permissions yet, but I have rebooted several times. I had an issue with the superdrive not recognizing DVDs, so I zapped the PRAM and did the SMC thing.  Plus, I've tried rebooting just to see if that would help, but it has not.
    I have been watching istat and there's some free memory but not a lot.  I was fine under snow leopard, I never had any troubles until I started running a lot of stuff at once.  I agree that this is almost certainly memory. It gets worse the more things I try to do at once.  Everything hangs whenever there's an operation to be done (syncing, downloading). It just feels like the machine is choking.
    I saw an article earlier on one of the Mac RSSs that the writer was having problems with Safari consuming up to a gig of memory just sitting idle with a few tabs open.  I'm not going to bother with Safari until I put the memory in, Chrome runs pretty well, even if I can't really do the full-screen thing.  I guess at this point I'm just looking for help for what I can do to conserve memory until more arrives.  And I'm a little annoyed at Apple for saying Lion works with 2Gb of RAM when it really doesn't.  If you can't use the browser or the iTunes, how can you even hope to run Photoshop?  iMovie takes 5 minutes to load and when it does it's full of visual glitches.
    I guess I'll try permissions and see if that helps. Thanks for your ideas though.

  • Nidaq OPC server performance issue

    I have an OPC client receiving data from the OPC server that is installed as part of NIDAQ and am finding the performance unacceptable.
    The client is used in another application to receive updates to 256 channels at 70Hz from a non NI OPC server over the network using DCOM and in this case the client shows about 1% processor usage and the server about 3%.
    With the NI OPC server I get about 2% processor on the client and 60% on the server and am limited to about 2Hz update rate with only 6 channels configured.
    I know the client is OK - any ideas how I can get at least 20Hz out of the NI OPC server?
    PS. Is this the correct place to ask this question? - there dosen't seem to be a place for NIDAQ questions.

    Any ideas where I might get an answer to this problem?

  • JDEVELOPER TP Reponse Time - extremely slow

    I am new to Jdeveloper and my first install is TP 4 (4.11.1.1.0.0) and it is basically unusable. When I click on New Application it takes at least 3 minutes to bring up the New Application window. If I highlight the name it takes another 3 minutes to allow me to enter one character. I have a high powered windows XP box with 4 Gig of memory and the app is only using 180Meg.
    All I did to install it was unzip the download and execute the jdeveloper.exe.
    Thanks

    Shay Shmeltzer blogged about making JDev faster sometime ago which you may find useful.
    In addition I also blogged that McAfee's disk-hog, ah, I mean Virus-Scanner also kills JDeveloper performance thanks to McAfee's lousy JAR file scanning. I can confirm this is still an issue for McAfee with the latest release as we've hit it at our current client's site.
    Both these articles are indexed at the Oracle Wiki.
    Hope this helps.

  • DBA related Issues

    Can anyone please help me in resolving these questions?
    1. A Developer call and tell you his/her process is running slow , where do you start and what you do ?
    2. Oracle is running slow , what tables you start with or what tables you are going to look at inorder to resolve this problem?
    Thanks

    1. A Developer call and tell you his/her process is running slow , where do you start and what you do ? In first place, a developer shouldn;t be working with production, he/she might with development database, I guess. I do care much if a end-user calls and complains about the performance degradation.
    If a particular process or query running slow, there are many ways to tune it. You can enable 10046 trace event, you can take the execution plan of the query and if possible tune it, you can check the wait events of the running query using v$session_wait, if you are on 10g, everything available with v$session dyanmic performance view. Perhaps, Oracle10g, has very reich feature of performance tuning.
    2. Oracle is running slow , what tables you start with or what tables you are going to look at inorder to resolve this problem?It depends on the situation, like if the db complite hangs or performance unacceptably, you need to find out whether this is happening on particular time, or when there is much load on the server, or it really performs badly all the time.
    I would start with taking statspack report in regular 15 min. time window to compare the db health.
    Let me tell you, to use 10g, AWR, db_hist tables, you need an additional licence from ORACLE.
