JDeveloper Hangs Up

I am running JDeveloper 3.2 on NT with Oracle 8.1.7 on an Intergraph TD-Z 2000. It has a 6 GB hard drive and 514 MB RAM.
I am having a problem with JDeveloper constantly hanging up.
Has this been reported before? Is there a patch for this problem?
Thanks
Dave

I upgraded to 3.2.3
With resolution set to 1280 x 1024 when I invoke the Entity Object Editor the application hangs up and the process must be killed.
I changed resolution to 1024 x 768 and when I invoke the Domain Wizard, the application hung up. I killed the process.
Now I can no longer run the JDeveloper application at all. Neither by double_clicking on the shortcut on my desktop, double-clicking on my project file, nor running the exe file itself.
The application hangs while initializing.
I'm thinking seriously about abandoning JDeveloper altogether and using another IDE.

  • ADF FACES: jdeveloper hangs on opening a .jspx file

    I may not have had this file open since updating to EA13, but I'm not positive. Upon trying to open the file (code below), jdeveloper hangs. It sucks down roughly 50% of the CPU and the memory footprint slowly grows (about 3 MB per minute). As of now, I've tried restarting jdeveloper and then opening the file, but the behavior is the same. I have let it run for nearly 15 minutes and it is still hung (to the point that the display is not redrawn when a window, such as the task manager, is closed after obscuring part of the jdeveloper window).
    I'm running jdev version 10.1.3.0.2.223

    Helo there,
    I am having exactly the same problem, everytime I include af:forEach tag inside the af:selectOneChoice for example, preview of JSP is not shown and whole developer hangs, in task manager I can see 100% CPU occupation by JDeveloper.
    But the code itself is ok, if I run the page while editor is in Source mode Page is properly shown in browser, but when I change editor mode to Design it hangs.
    I am using Faces EA17 and JDeveloper 10.1.3
    Does anybody else face the same issue?

  • JDeveloper hangs on startup

    Hi
    I have tried to install JDeveloper on my standalone PC.
    I had JDeveloper 1.0 working but then tried to install
    the 2.0 beta. Since then no matter which version of
    JDeveloper I install (1 or 2), when I run it, it simply displays
    the title graphic and then hangs. I have deinstalled
    all previous versions, and no errors are reported when
    installing. I have a Windows NT machine with 128 MB RAM,
    256 MB virtual memory and the following other Oracle software
    installed (in three homes, as reported by Universal Installer):
    OraHome81
    Oracle 8i Enterprise Edition 8.1.5.0.0
    Oracle 8i Client 8.1.5.0.0
    Oracle Programmer 8.1.5.0.0
    OraHomeWebDB
    Oracle 8 Enterprise Edition 8.0.5.0.0
    Oracle Designer Release 2.1.2
    WebDB 2.0.5.6.1

    OAS Enterprise Edition 4.0.7.0.0
    Oracle 8 Client 8.0.5.0.0

    What could the possible problems be? I suspect that
    the Aurora system is not starting properly.

    Hi
    JDeveloper 2.0 has been in production for a while. Don't install
    the beta software anymore. Try with the production release.
    Aurora is part of 8i and JDeveloper has a client library for
    that. There is no dependency for that during startup.
    Make sure that your PC has equalto or more than 256 colors in the
    settings

  • JHS11 TP2 - Jdeveloper hangs when generating application

    Hi,
    I have got an issue with JHS11 Tp2.
    When generating the application JDeveloper seems to hang (I waited about 10 minutes before I killed it.).
    In my jdev console I see the following :

    The last JDeveloper logline (at the bottom of the IDE) is : Load done oracle.jheadstart.model.adfbc.security.query
    I tried to use a different jdev_user_dir but that did not solve my problem.
    Reinstalling JDeveloper did not solve my problem either.
    Do you have any experiences like this?

    Hi All,
    I found something. In my model.jpx file I found the folowing tag multiple times (about 3500 times):
    <AppContainee
    Name="JhsModel"
    ObjectType="JboProject">
    <DesignTime>
    <Attr Name="_SourceName" Value="jhsadfrt-11.1.1.jar"/>
    </DesignTime>
    </AppContainee>
    When I deleted all but one occurrence the generator performed normally.
    Can you tell me how to prevent this behaviour?
    Regards,
    Romano

  • JDeveloper Hangs in Win2K

    JDeveloper 3.1.1.2 Hangs and Causes Win2K to crash completely. It does this very often while it loads the plugins.
    How can I avoid this problem. Any workarounds?
    Thanks

    The problem is odd, I check the Task manager when I try to open the page. I get some CPU spikes but nothing major, and memory looks okay, over 1.5G available. This odd thing is that this is particular to certain JSPX pages we have written. Some load fast and some load slow/hang. I have check the JSPX and the Binding and I can see any common factors. It feels like JDev tries to get access to something during the setup of the designer for the page but is blocked? On some pages we are waiting 4-5 minutes for the designed to show the page.
    I don't think the pages are very larger (what is large?), I mean we have a good number of components particularly Panel Groups etc.. As an example one of our pages which takes time has the following, 2 tables, 2 select many, 2 Box Layout, 3 buttons, 1 text field. 3-5 minutes to load.
    Thanks for your help.

  • JDeveloper Hangs

    I have the following client configuration:
    - Windows 2000
    - Oracle 8.1.6 DB
    - Just loaded JDeveloper version 3.1.1.2
    I have the following server configuration:
    - Windows NT
    - Oracle 8.1.6 DB
    After loading JDeveloper, I restart my PC. After launching JDeveloper, it hangs while trying to load. The JDeveloper window title bar displays "Oracle JDeveloper [Loading addins..].
    Is there a problem running JDeveloper on the same system as the local DB? Is there a conflict with the DB on the server? My local connection is set up to JDBC-thin.

    Problem Solved!
    After a day of investigation, I was able to activate JDeveloper as follows:
    1) I ran JDeveloper and it hung.
    2) I checked the Application Log on the Windows 2000 Event Viewer.
    3) The last item in the log had the following message: "WMI ADAP was unable to load the perfproc.dll performance library due to an unknown problem within the library.
    4) I searched the web and found that this was a known problem.
    5) The given answer was to run "exctrlst" from the command prompt, and to disable(uncheck) the performance counter.
    6) Once done JDeveloper loads and operates properly.
    If anyone also has encountered this problem, please post on this topic.

  • JDeveloper Hangs in JSPX design mode

    hi,
    I have been working with a project in JDeveloper (ADF Faces) the last six months and things have been going fine. Now that we are only a few weeks from release we are suddenly getting performance problems and the IDE hangs on certain jspx pages when we try to show them in Designer Mode. Our version is 11g (11.1.1.0.0).
    We get the following IDE exception:
    SEVERE: lock starvation; thread 'status-0' blocked on lock 'orderclosure.jspx' for more than 20,000ms:

    We need to solve this fast, can anyone give us some pointers.

  • BUG JDeveloper hangs when Completion Insight invoked with accelerator

  • JDeveloper Hangs when debugging JPDA on Solaris

    Has anyone been able to JPDA debug on the Solaris platform? My system hangs when a break point is encountered.

    I need more info so I can help:
    What JDK do you have?
    What VM are you using when you debug? (Project Settings Dialog, Runner panel, Virtual Machine combobox).
    Can you copy the java command from the debugger log window and paste it into your reply here?

  • 10g BPEL process upgrade to 11g hangs in Jdeveloper and Ant script

    I have successfully upgraded several 10g (10.1.3.4) BPEL processes and ESB services using Jdeveloper 11g (11.1.1.6.0) migration wizard and deployed them to an 11g environment. Both 10g and 11g environments are up and running.
    However, my 11g jdeveloper hangs when migrating the next BPEL process. It hangs at the message box with the title: "Migration Status". I tried the Ant script and it hangs too. It hangs after printing out:
    "CompositeRefs
    [upgrade] WARNING: UPGBPEL-02009: No Binding setup for : "soapCheckPrivileges"
    . This will cause compilation of the upgraded project to fail. Check SOA Upgrade
    documentation on manual steps necessary to bind this composite reference. If ne
    cessary, upgrade and deploy any dependencies. If planning to retain 1013x nodes
    in this projects dependency tree, check earlier part of this log for 1013x WSDL
    URLs that can be used."
    I guess it makes sense since Jdeveloper and Ant script use the same code base for migration.
    One other observation is that if I kill the hanging jdeveloper process and reopen it and go through the migration wizard again, it will be successful without hanging. However, when I fix all the wsdl reference and do a build and deploy to sar. The resulting sar is defective and cannot be deployed to Weblogic even if both build and deploy to sar report success. The defective sar contains only scac.log and scac-log.xml, not even composite.xml.
    One difference between this BPEL process and others I have successfully upgraded is that it depends on an ESB service (this esb service has been upgraded and deployed to 11g).
    Any ideas?
    Thanks,

    I will answer my question. I killed the migrating Java process and the migrating wizard will report failure of migrating the .jpr file. Actually, the only thing missing in the migrated .jpr file is deployment profile which I can generate from deployment menu. And I can deploy the migrated process. This works as a workaround.

  • JDeveloper 10.1.3 EA1 hangs during JSF development

    Hi,
    Create a new project (web project) and invoke the JSF JSP wizard to create a JSF page. Click on the source editor and try editing some code or copy and paste code from another JSF application. JDeveloper hangs. It is using almost 100% of CPU. I have to kill JDevW.exe in the task manager to get my system back to normal. Right now, it is becoming impossible to do any JSF development at all with the EA1. Please advice.
    Thanks

    Hi,
    It works now. I do not know what has a changed. The only thing that I can notice is that I am using a new workspace. Previously, I created the JSF project under a workspace that consisted of many projects; most of them were a direct checkout from CVS. Anyway, thanks for you help. I will let you know if I come across the problem again (of course with the actual step to reproduce the issue).
    Thanks

  • 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 and SuSE linux

    Hi all
    Does anybody else use JDeveloper 10.1.3 with SuSE linux ? I currently have SUSE linux 10.0, (kernel 2.6.13-15.8-smp), JDev version 10.1.3.0.4 SU2I with jdk 1.5.4 and I am facing various problems where JDeveloper hangs or behaves unexpectedly. For example if I create a JSF page as a jspx document then the visual editor does not display data correctly.
    My machine is 2.8 GHz P4 CPU with 2 GB of RAM so I do not think that I am having any problem with my system resources.
    I have also read somebody else complain about the debugger being very slow on SuSE linux so I want to know if anybody else is facing similar problems.
    Thanassis

    Hi Guys,
    I no problem running jdev 10.1.3 on my latest SuSE ;). however, i got problem in running the debugger. the problem is the debugger stepping so slow. each step takes about 5-10 seconds . i have no idea how to solve this problem. but it has no problem on kubuntu 5.10 at all. i wonder i could be the kernel. but just my guess only.
    please let me know how to solve it. thz guys.
