Progress bars dont work in a cluster environment

When you go to the host:port it works but when you go to the link in a clustered environment they stop working.
Any suggestions?

I am using jdev 11.1.2.1. I have 3 progress bars on the page. two of them render and the third one does not.
It renders perfectly in a non cluster environment. I am not seeing where the problem is.

Can Contribute work in Web cluster environment

Hi
I have 2 web servers behind load balancer. Our websites are identical on these two web servers. We use load balancer to direct http traffic to split the load of internet hits. We have a central server behind these 2 web servers. Our web editors can map network drive to the shared folders on that central server and update html files. I have replication software configured on central server to replicate html files from the central server to our web servers.
Is that possible to use Contribute in our environment? In order to create a connnection, I have to enter a http URL first, and then I enter the shared path on central, it gave me error "cannot verify your connection information". I am sure the URL (not URI) I entered doesn't include file name.
When I use Contribute to connect to a standalone server, it worked fine.

> When I use Xcelsius it really crashes/freezes up when I have just a medium amount of data in the XLS tab. I want to be able to expand Xcelsius use in a production environment where I am updating the data on a frequent basis and it would support a larger data set.

Xcelsius itself seems to be prone to locking up, crashing, etc. But when you export to Flash and use the flash object (say in a web page) I haven't seen that. With large data sets it can take time to intialize, though.

Yes, you can use Crystal to read and process the data, then pass it to a flash object you created in Xcelsius. See the chapter Integration with Crystal Xcelsius and Flash in Crystal Reports 2008 - The Complete Reference.

Conduit bar dont work in new firefox version

I have a personal Conduit Toolbar and since I have installed Firefox 14 beta it doesn't work. What´s happen? In other browser (all) it work's fine, only in Firefox doesn't.

Hi Eandrade, can you link to the download page of the toolbar? It might be that it's not yet compatible to the latest version of Firefox. Unfortunately I don't know which toolbar you mean, but if you link to it I can have a look.

Progress Bar Never 100%

Ok, kind of an odd issue, but I've got a script that can take a considerable amount of time to run due to all the sub-scripts. Anyway, I've setup a progress bar to work with it so I can tell how far it is. The only problem is, unless there is an alert or something that pauses the script (like a pop-up), the bar NEVER shows 100% full; even if I use an in-script pause such as the sleep command. Any ideas how to fix this? An example script is below and also never reaches 100% filled bar.
#target photoshop
var list = ["one", "two", "three", "four", "five", "six"];
var w = new Window ("palette");
var progress = progress_bar (w, list.length);
for (var i = 0; i < list.length; i++) {
    progress.value = i+1;
    // user functions
    $.sleep (400);
progress.parent.close();
function progress_bar (w, stop) {
    var pbar = w.add ("progressbar", undefined, 1, stop);
    pbar.preferredSize = [300,20];
    w.show ();
    return pbar;
I've also tried adding "w.show();" immediately after the "progress.value = i+1;" and still nothing; but like I said, if an alert pauses the script, it will work right. Any ideas?
Thanks for any help!

Lol, ok, now I feel stupid. I actually found the fix for the issue on my own. To fix it, simply replace the $.sleep(400); with w.update(); (the sleep is pointless and pretty much just slows down your script).

How do I programmatically change progress bar limit?

Hello all. I have a custom control and one of the indicators is a progress bar. The bar is used to show the position of a life test fixture as the fixture moves up and down. I would like to have the max limit of the bar to be set by the user. The user enters a number and the bar maximum will be that number. That way the bar is more indicative of actual fixture movement. How would I programatically do this?
I read about using the Range property, but I can't seem to access it. Is this because the progress bar is part of the cluster? Would I need to separate the progress bar from the cluster, get the Range property set up, then put the bar back into the cluster?
My problem here is that since this is a custom control, it is set as a typedef, with my vi using 12 copies of it. So if I can't get the typedef to accomplish what I want, I guess I'll have to break the link between the typedef and the vi, go into the vi, and edit all 12 custom controls to do it.

Hi Dhouston
please find the ZIP file attached. somehow i can't upload a VI
Eventhough the cluster is a typdef control, you can still right click the slide inside the cluster and create a property node.
hope this helps

Cluster environment / OBIEE 10.1.3.4.1

Hi All,
Can anyone give me more information on Clustering
1> Can we make schedulers work in a cluster environment ?
2> Max number of servers in a cluster configuration ?
Thanks
Goutham

The Cluster Server allows up to 16 Oracle BI Servers in a network domain to act as a single server.
Schedulers can also work in a clustered configuration however only one instance will always be active...
Active Scheduler. An active Scheduler is a clustered Oracle BI Scheduler instance which actively processes Scheduler jobs. The Cluster Controller determines the active instance at runtime and notifies the Scheduler cluster of this instance.
Inactive Scheduler. An inactive Scheduler is a clustered Oracle BI Scheduler instance which is not actively processing Scheduler jobs but is ready to take over in the event of an active Scheduler failure. An inactive scheduler is idle at all other times.

Indeterminate progress bar

There is an ancient thread on the subject already, but with no answer, so i decided instead of ressurecting that one to start a new qestion?
How to create a indeterminate progress bar, when you can't update/acces the palette with te script (for example when exporting a few very large documents).
I know Marc managed this kind of voodoo sometime ago, but i don't know if he is willing to share the trick, as it has been incorporated in some of his paid scripts.
So.. does anyone else have any ideea how it can be achieved?
I have been triying to use a embeded swf as a progress bar in a palette, but the palette only gets updated something like "onIdle".

I have to do the other stuff in another thread because otherwise the progress bar doesn't work right, yeah its really stupid. It is of note that this code is called from a GUI interface. Because I am calling this progbar from the GUI, it executes the progress on that thread. The only problem is that nothing else can be run on that thread when the progress bar is working, so rather than call a method, I have to create a whole new thread to do the operation.

Need help with Threading GUI progress bar

Anyone able to help? I'm sure you've seen this a million times. I've google'd around and tried examples but still can't get a progress bar to work properly under the following situation:
1. Created a panel with several components to select directory, display directory in tree etc.
2. When a specific button (Search) is clicked, I want a secondary window to popup and report progress of searching down the directory.
As you'll probably guess, the progress window isn't being updated until the end. I'm using Threads and using InvokeLater but nothing happens. Is there any good example that does the above? I can't seem to find one to figure this out.
Thanks
Speedy.
Sample code:
main.java:
========
public class Main {
public static void main(String[] args) {
MainPanel mainPanel = new MainPanel();
mainPanel.show();
MainPanel.java:
============
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
public class MainPanel extends JFrame implements ActionListener {
public MainPanel() {
this.setSize(100,100);
JButton startButton = new JButton("Start");
this.getContentPane().add(startButton);
startButton.addActionListener(this);
public void actionPerformed(ActionEvent event) {
ProgressPanel pp = new ProgressPanel();
pp.show();
SimpleTask st = new SimpleTask(pp);
st.start();
while (st.isAlive()) {
System.err.println("waiting..");
try {
Thread.sleep(100);
} catch (Exception e) {};
System.err.println("finished!");
SimpleTask.java:
=============
import javax.swing.SwingUtilities;
public class SimpleTask extends Thread {
ProgressPanel pp = null;
public SimpleTask(ProgressPanel _pp) {
pp = _pp;
this.setDaemon(true);
int i = 0;
String position = "";
public void run() {
Runnable updateGUI = new Runnable() {
public void run() {
pp.setText(position);
try {
for (i=0; i<50; i++) {
position = "Now on = " + new Integer(i).toString();
System.err.println(position);
SwingUtilities.invokeLater(updateGUI);
sleep(100);
} catch (Exception e) {}
ProgressPanel.java:
===============
import javax.swing.JFrame;
import javax.swing.JLabel;
public class ProgressPanel extends JFrame {
private JLabel label = new JLabel();
public ProgressPanel() {
this.setSize(200,200);
this.setLocation(100,100);
this.getContentPane().add(label);
setText("Start");
public void setText(String text) {
label.setText(text);
}

Ok, I'll look down that road. I should have said the Thread is being used because the current while loop will be changed to perform real work. Just an example at the moment to show what I'm trying to do. Does this make a difference? The real task will be to drill down directories, counting file types/dirs etc...

Strange progress bar

I'm having this strange problem with the progress bar in the gallery section of my site. I made the site on flash.
Go to the English section and click any image. you'll see the progress bar not working but wait a bit untill the gallery loads. There's no close button but if move your mouse pointer to the up right corner it's there, click it. Now click on the same image and you'll notice that now the progress bar and close button works fine.Anyone got a clue?
index
It's weird because when i publish the site and test it on my computer it works fine. But when i upload the files to the server this happens.
Thanks for your time

Thanks you. Yes, i've reached the conclusion that the problem only happens in certain web browsers. I've installed firefox and it works fine. But on certain versions of IE it doesn't. The scale, border will be corrected. It was only a test file.
So what should i do for it to work on all browsers?

Is it possible to have a progress bar on a J3d-applet?

I wonder if it is possible get a download progress bar to work on a J3d-applet. I have to do this with a JProgressBar, which is a Swing component. I have heard that it is hard to get Swing to work with Java3d. Is this the case?

You can try to add Canvas3D in some container like JFrame, JDialog or what ever you are using and add JProgressBar to that container as well. You may use appropiate layout as well. JProgressBar cannot be a part of your 3D world. But if u want to use simple components like Label or TextFields then u could use Overlay library at j3d.org

Web Services Session /Singleton cluster environment

Hi!
I am having trouble figuring out how to do sessions in web services.
I am trying to build an app that uses multiple GUI's in different languages (not java) and we want to implement our business layer with web services.
I need a session to save user settings, and user info so that I can avoid going to the database and ldap in every call.
So far my idea is to have a web service that deals with the authentication. If the user is valid, the web service will save in a singleton that has hashmap the user setting and return to the client the hashmap key as a token.
The client has the responsibility to save the token and to use it in later calls.
The problem that I have is that a singleton would not work in a cluster environment! And I really don't want to be passing all the user information between calls
Any ideas how can I solve this???

Hi Gaurav,
Yes, the currently running session will be taken care of by the another server node which is up and running.
Your question: Does this mean that the a session of WebDynpro application will continue to work or the changes are lost and the user needs to login again?
"The state of the session is maintained in the persistent storage after the last successfully ended request." Which means that for example a user was filling up a form and haven't saved the changes and the server crashes then the data on that form will be lost when the second server node starts processing the request. But if the user had saved the data before the server crashes that state of the session will be stored and the data of the form will be saved and user need not fill it up again. If the Server crashes in between the HTTP request session then the request is assinged to the another server node to generate the response. In none of the case user needs to login again.
Your question: Fundamentally the question is what WebDynpro uses behind the scenes for maintaining session?
It uses Java Serialization to serialize the HTTP Sessions
"Serialization involves saving the current state of an object to a stream, and restoring an equivalent object from that stream. The stream functions as a container for the object. The information stored in the container can later be used to construct an equivalent object containing the same data as the original."

Progress Bar Issue Actionscript 3 Adobe Air Program

I'm currently having an issue where when I download a file from the internet, I update the source for a ProgressBar that I've created, and I set the ProgressBar to event mode, and as the file is downloading, the progressbar's value increments as normal. When I re-download the same file (source has not changed), the value of the ProgressBar is no longer accurate or producing the same value as before. Basically, the ProgressBar works correctly only 1 time when I launch my application. Is there a proper way to reset/update the ProgressBar after each download?
I've tried everything I can think of.

Right if I had to paste the code it would take several pages lol. I haven't tried using a custom progress bar, but I may look into that. The main feature I used from the Progress bar was the ability to see how many "bytes" had been downloaded and I presented that to the user. I'm using a combination of urlStream/fileStream to download the file. And the source of the ProgressBar Component is linked to an instance called download which handles all the downloading of files. So I use the progress Event to monitor when a download is taking place, and at the same time calculate how many bytes have been downloaded. This is probably not the best way to do it, but currently the only way I know how with my limited actionscript 3 knowledge.
I have confirmed at least my download class/package is downloading the full file each time even though my Progress bar only works 1 time, so it could be some of the things you pointed out that is causing it.

Repeater, Image, Progress Bar drama.

Okay so I'm loading images dynamicaly from a database,
passing the data to an Object variable and then to the repeater. I
can load my images just fine, no real issue there, but I cannot get
my progress bars to work. Any ideas?

You need a way to refresh your code. I'd recommend throwing
in a setInterval in there.
funtion myNewFunction() {
infoLoaded = imageLoader.getBytesLoaded();
infoTotal = imageLoader.getBytesTotal();
percentage = Math.floor(infoLoaded/infoTotal*100);
infoField.text = percentage+"%";
if (percentage>=100) {
delete this.onEnterFrame;
infoField._visible = false;
setInterval(myNewFunction, 15);
//something like that.
