What JVM do you use?  What is the best choice?

We may be rolling forward Discoverer 10.1.2 sometime in the near future. The current release uses Sun J2RE 1.4.2-06. There is a J2RE 1.4.2-09 available, as well as JRE 5.0 Update 5. Deploying JVMs is a pain when potentially hundreds of PCs are involved, and I'm sure there will be a version of Discoverer sometime in the future will prefer a different JVM.
What's the best choice, which JVM is supported & solid with the existing 10.1.2 release as well as potential future releases?

Hi,
the plus works as standard with J2RE 1.4.2-06. Right, but that isn' a must cause you can change that.
Oracle said this:
"Dynamic Versioning for SUN Plug-in is a standard Sun feature and is described at Sun website:
http://java.sun.com/j2se/1.4.2/docs/guide/plugin/developer_guide/using_tags.html#in-ie
The changes documented are not supported by Oracle. While the changes documented have been tested on a limited number of platforms, these changes are provided without any claims to their accuracy"
The solution is easy:
1. Under the path ...\discoverer\config from App-Server you find the 'configuration.xml' file
2. Open this file and search for 'jvm name' for 'sun'
3. Change the classid="clsid:CAFEEFAC-0014-0002-0004-ABCDEFFEDCBA" (static versioning ! ) through this classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" (dynamic versioning !!) and save the file
4. Restart the discoverer App-Server - ready
From now the Plus will use every version above J2RE 1.4.2-06 and only if there is an older version he will download his own version.
We tested this with several versions 1.4.2-xx and with JRE5-3. It works.

Norbert

  • What application are you using for student collaboration?

    The only part that is missing from iTunes University is real time student collaboration. What application are you using to bridge the gap? Thanks, Ed

    Yeah, I'm not sure I know what you mean either. 
    Q:  If you're asking which server-side code to use on Windows IIs Servers?
    A:  ASP or ASP.net and MSSql.  Since Microsoft built these languages, you would get the best support from MS Expression.
    If you're asking for software that helps you write code, you'll need to be more specific about which code you want to write and for what purpose.

  • What JVM is being used in my Internet Explorer ?

    I have a web-bases/java-bases application that does not work when JRE 1.4 is active.
    I disable it for Internet Explorer in the Java Plug-In Console on the Browser tab and then things work fine.
    How do I know what JVM is being used then ?
    Some configuration info :
    WinME, IE 6.0, JRE 1.4

    When you install JRE1.4.0, it asks if you want to link the JRE to IE and Netscape 6...if you answered yes, what it does is to create and automatically select a new option box in IE (see Tools-->Internet Options-->Advanced-->Java Sun-->Use JRE1.4.0...) -- if you elected not to link the JRE, the option box is not created.
    Without the new option box, IE works like this:
    1) Unless the applet has been converted with the HTMLConverter that comes with your SDK, IE will run the applet with its native JVM which is version 1.1.5.
    2) If the HTML file has been converted, IE will check to see what version of the JRE is required and what is already on the system. If a different JRE is required, it will prompt the user to download the required JRE and then run the applet -- if the user doesn't want to do the download, the applet will simply fail to start.
    Hope this helps!

  • What method should be used for resizing the particular JTable Column width

    I have a four table. Only one table which are on top have a table header. I want that when user resize the topmost table with a mouse other table colume also be resized automatically. So I want to know that what method should be used for resizing the particular JTable Column width.
    Thanks
    Lalit

    maybe you can implement a interface ComponentListener as well as ComponentAdapter with your topmost Table.
    for example:
    toptable.addComponentListener(
    new ComponentAdapter(){
    public void componentResized(ComponentEvent e){
    table1.setSize(....);
    table2.setSize(....);
    /*Optionally, you must also call function revalidate
    anywhere;*/
    );

    If your PC fits the following specifications, you can setup iCloud to automatically sync contacts with your iPhone:
    Microsoft Windows 7 or 8
    iCloud Control Panel 2.1.2 or later
    iTunes 11 or later (for iTunes in the Cloud and iTunes Match)
    Outlook 2007 or 2010 or iCloud.com
    Safari 5.1.7 or later or Internet Explorer 9 or later (for iCloud.com and Bookmarks), Firefox 16 or later or Chrome 23 or later (for iCloud.com)

  • What tool do you use

    Hi,
    I have a warehouse environment with planing data. Partitioned tables by range ( date) mainly.
    Size is in > 1 - 6 TB. ( 9R2 and 10gR2 on AIX)
    Using GControl only.
    I'm wondering what could be the way to create subsets of the production database, for test purposes?
    Are there any effective 3-rd party tools/suites or native Oracle functionality?
    What one should look into eventual 3-rd party tools?
    What do you use?
    Thx,

    The idea of using a different schema is just so that you can keep the same table_names and schema in the target database for the selected data. You would be able to use a full export and import of the special schema that holds all of the data of interest.
    Instead of CTAS you can use CREATE DDL followed by INSERT SELECT statements for your partitioned tables.
    There is not built-in feature to quickly do what you want without serious study to understand the data relationships and target the data in question. The query= on an export might be useful but extracting the data into holding tables is probably the better route where the number of objects is not one or two and the relationships vary especially if some of the relationships are not defined to the database.

    And so I wondered, what do you use? IMO a terminal font should be, readable, monospaced (doh) and a little thick.

  • What browser are you using with OS 9.x?

    Would you all please state which internet browser you are using with OS 9.x and the strengths/weaknesses you are experiencing with it?
    I switch back and forth between Mozilla and Internet Explorer but fewer and fewer websites work properly with them. If there is a better browser than those two I would add it to my old Wallstreet running 0S 9.1.
    Again, what browser are you using with OS 9.x and what are its good/bad points?
    Thanks!

    (Almost forgot
    I have an iCab filter set up for Yahoo on my OS 9.2.1 iMac.
    For the URL string I use (asterisk)yahoo(asterisk)
    For the Scripts filter I use the Netscape identity and have all versions checked except "JScript", and everything is checked in the "Allow" section.
    For the Network filter I use the Firefox identity and have the HTTP "referer" set to "Always".
    I don't use Yahoo Mail much on that machine, but those settings allow me to use the Address book to select addresses and send messages with attachments. (I'm not sure about viewing attachments, though, and I'm almost positive that address auto-complete doesn't work.)

  • I'd like to get your opinion: POLL: What font do you use?

    People,
    I am curious to know what font you guys use for text in your various corporate projects? I'v used Helvetica for years, as it is corporate and clean, but I am looking for others.
    POLL: What font do you use - let's say for corporate brochure/annual reports texts?

    Jack,
    You may also have a look at some of the font talks in the Typography forum, or start a thread there; among the latest was this one: http://www.adobeforums.com/webx?128@@.ef602ce.59b709a5
    Obviously, the wrapping should fit the contents.
    When all is said, I still prefer the fairest font.

    I had built an integration between Sitecore and Eloqua and posted some info on the AppCloud.

  • What Camera are you using?

    Hi,
    What camera are you using for you shot?Let share about the Semi Pro cam together: Fix Lens with manual Focus and Zoom,Affortable Price...

    Well, before I got my Digital Rebel XT I dreamed of the Powershot S2 IS. Then the S3 came out...but I was hookoed on my Rebel XT. I hear the S5 is a monster...
    Now, my 20D is probably more prosumer. I wouldn't call it a pro camera, although it is legendary for it's use on the sports areana and weddings by pros. For my money, any camera with a pop-up flash and automatic modes is not a pro camera. Having said that, I hope no one starts throwing eggs and tomatoes!
