10g: Cube build performance:Waiting for tasks to finish

I had a question related to cube build performance. We see the following in the OLAPSYS.XML_LOAD_LOG prior to completion of parallel processing. So basically the loading of records etc. happens in 2-3 mins but then the part for "running jobs and started 6 finished 5 out of 6 tasks takes almost 30-40 minutes to complete". At this point in background it invokes the xmlloader and xml_parallel_loader. Any insights as to what specifically this steps do (solving of measures etc.) ? Also what we need to modify in terms of xml tag or anything else to improve these timings?

Thanks,

When we checked the scheduler jobs we saw xmlparallel_loader. in terms of v$session_wait we saw a db file sequential read. Following is a snapshot from the stage of finished updating partitions to starting of parallel load. Please advise.

NI Scope Wait for Acquisition to Finish Obselete in 2014

Quick Question,
In LabVIEW 2014, the NI scope Wait for Acquisition to Finish subVI is no longer used and is obsolete apparently, can some one tell me why this is and what I can use instead with the new 2014 NI scope blocks?
Thanks for your help!

Query Acquisition Status until Status is "Complete" To avoid infiate loops (missing trigger event) you should set a Timeout for the loop
Alternately use hardwae and rout the End of Acquisition event to something

Update of jlabel does not happen when i wait for thread to finish (join())

gurus please help.
I have a main application which in actionevent calls a thread, that thread calls parent method to update ths status in jlabel, but when i use thread.join() to wait for process to complete, the jlabel does not get updated, please tell me how can i update the jlabel, i have to wait for thread to finish and during run i need to update the jlabel.
thanks

hi camickr and gurus:
here is the code:
notice after pressing the Process button, the label is being updated but its not working. I called the processnow() method directly and also by thread, but in thread I have to wait until it finishes using join() but still does not work, please help. Thanks

Error while loading a Cube in BW - "Waiting for Semaphore"

Hello Experts:
I seem to be having a frequent problem while doing a Delta load from BW (3.5) cube to exactly similar cube in BI 7.0.
The load is done daily via a Process Chain. Before doing the Delta load, I also have a step to DELET Index from the
cube in BI. The Delta loads have been successful but frequently they take about 7 or 8 hours to load. The number of
records are not many 80,000 to 140,000 records range. There have been successful loads for similar range withing
7 or 8 minutes. However, when it gets hung up it takes 7 or 8 hours.
Looks like it is a Lock happening in 3.5 BW system. Tcode SM12 shows that it is locked and then in T. Code SM66, it
shows that it is hun for resources..... The message inicated is "Waiting for Semaphore". After about 7 hours, the load
automatically happens.
This is causing issues becuase the upward data loads don't happen and Users can not access the data until late afternoon
for their planning in BPC.
Is there a way this error or Waiting for Semaphore be avoided or time is reduced....? How can I achieve this? Any
fne tuning tricks anyone can suggest please......!!
Thanks a lot in advance.

Thanks to both of you.... ppreciate the feedback. I guess, I will have to wait for the situation to arise again as today's delta went normally. I will see if this happens again. I am not sure whether the Semaphore number is same as the "Work Process Number" in SM66 (which was 3 in my case) or is it the Process ID (which is 22872082 in my case).
If I go to SM50, I shoudl find either the Process ID then.
Would I be searching for the OSS notes corresponding to Process ID (in this case 22872082...? or would it for sempahore number (if it is different .... as I mentioned 3 in my case..?
Could you please clarify which is Semaphore number and if it is same as the process ID I am talking about so that I can search for the right OSS notes.
Also, finding all this will only tell me why it hung.... but is there a way we can make it kick off and not get stuck or I have to wait it out until the resources get released.....? Which in my case then would stil be a wait for 6/7 hours!!
Apreciate your feedback.
Best..... Lee

Waiting for Task Completion from multiple users

iam using Weblogic8.1 Integration BPM to design a worklist application. I need
to create a number of Tasks(number know only at runtime), assign to users and
wait for the completion of each of these task. I've tried using the Task Control
factory to accomplish this. But iam not able to hold the process instance execution
till each of these task is completed. The control gets released from the TaskControlFactory_onTaskCompleted
as soon as one of the above created task is completed.
Pls. let me know if there is a way to achieve this.
Regards
Raja V.

Try to put the onTaskCompleted Control Receive in a loop which counts how
many of these
callbacks have already arrived, and the loop exit condition would be that
the count is equal
to the number of the created tasks.

Wait for commit to finish

Hello,
I am calling a standard function that update some tables and at the end execute a commit work without the wait clause, but right after the execution of the standard function I need to perform some operations that needs all the tables to be updated, so unfortunatelly I needed commit work and wait inside the standard function.
As I cannot change the standard function I tried to use table VBHDR to check when the update process finish but I noticed in my system this table is not trustfull as there are lots of garbage there with field VBRC = 1.
So my question is how can I wait for the commit work to finish in this situation?
Regards,
Mauricio

well this a random approach but u can try this.
use WAIT UP TO n seconds give the vales as some 120 or 180 seconds.
but u cant be sure if its stable all the time.
Or u can try and call the function with the addition IN UPDATE TASK

Second tween does not wait for first to finish

Having a little problem here and as far as I can tell it is
just that the second tween starts before waiting for the first to
finish. Basically on a click event it should slide out a scroll
pane to the bottom of the screen, change the contentpath of the
scroll pane, then slide it back up.
with the code below it just slides up the new movie clip but
does not slide out the old one, if i remove the code for the new
clip to slide up the old one does do the slide out how I want it to
look.
how can I make a pause in between the two to wait.
on (press) {
import mx.transitions.Tween;
import mx.transitions.easing.*;
_root.mask._x = 54;
_root.mask._y = 109.3;
_root.scroll_pane.setMask(_root.mask);
switch (_root.loaded_clip)
case 2: var Slide_out:Tween = new Tween(_root.scroll_pane,
"_y", Bounce.easeOut, _root.scroll_pane._y, 900, 3, true); break;
_root.scroll_pane.contentPath = "Search_mc";
var Slide_up:Tween = new Tween(_root.scroll_pane, "_y",
Bounce.easeOut, 900, 109, 3, true);
_root.loaded_clip = 1;
}

Its still not working with that code but I think I can muck
around with it and figure it out, the slide out works on the old
clip now but then the new one never shows up.
The onMotionFinished was basically what I was looking for,
think I can eventually figure it out from here, thanks for the
info.

Automator doesn't wait for app to finish launching.

During "watch me do" actions that lauch an app Automator does not wait for the app to launch. This seems like a bug since Automator does infact know it is launching an app, this shouldn't be something that should require a sleep every time.

Did you try one these actions?

Make jFrame wait for jDialog to finish

I am making a project in Netbeans i have a main Frame and some Dialog windows that open up if you press some buttons.
when one window opens i want the main Frame script to pause and wait for it to complete.
i have tried 3 different ways:
questionDialog.setVisible(true);
while (questionDialog.isVisible()) {
    try {
        Thread.sleep(200);
    } catch (Exception e) {
} but that shows the frame of the dialog box but never loads the inside and the whole application freezes.
java.awt.EventQueue.invokeLater(new Runnable() {
    public void run() {
        questionDialog.setVisible(true);
while (questionDialog.isVisible()) {
    try {
        Thread.sleep(200);
    } catch (Exception e) {
}that loaded my Dialog box but the script never waits for it to close i assume it is because it waits until "later" to show the dialog box and in that time it skips the while loop.
Thread t = new Thread(new Runnable() {
    public void run() {
        questionDialog.setVisible(true);
        while (questionDialog.isVisible()) {
            try {
                Thread.sleep(200);
            } catch (Exception e) {
t.start();
System.out.println("Dialog started");
System.out.println(questionDialog.isVisible());
try {
    t.join();
} catch (Exception e) {
}but that had the same result as the first code it waited but never showed the dialog.
where am i going wrong how should i go about this?
Scott.
EDIT:
by finish i mean become not Visible. so isVisible() will return false
Edited by: ratcateme on Nov 20, 2008 3:02 PM

You don't have to do anything to do that
questionDialog.setVisible(true), this method will block the thread, it would't keep going until the questionDialog is unvisible, this is the mistake of the way 1 and way 3.
and the way 2: the while block will be execute before the questionDialog.setVisible(true) is execute, so questionDialog.isVisible() will return false
my en is very poor, good luck!

Hp34970a read vi doesnot wait for scan to finish

hi all.... i am facing problem ..im tryin to read DC current values from two channels.. i modified the advanced scan vi example..
the read
vi is not waiting for the scan to finish.... i used trigger vi outside
a for loop and i want the readings to be taken for a number of times
which is equal to the trigger count.... i even placed a time delay
between the standard event vi and the read vi....the standard event
register vi has been set for operation complete bit. Yet the read vi is
not waiting.
so can anyone let me knw if the delay helps in waiting the read vi to finish the scan??
will the read vi give out the readings for each scan or will it just display random values??
im
posting the vi here... i kept the scan count to be 15 and scan-scan
interval as 1sec. ( so it implies that im using a timer source for
triggering) I used a time delay of 0.9secs in between standard event
register vi and the read vi.
i used a for loop insted of
a while loop coz i need the number of readings = scan count. i placed
the trigger vi outside the for loop.
can anyone have a look over this vi and help me out?

final2.vi ‏59 KB

Now I placed a while loop around the standard event register vi and i am running it till i get a true in the bits set output. this time i checked the parameter'operation complete bit' instead of setting it. Only then i can see true value on the bit set output or else false.
The bit 1 is true after some time (after scanning is done), but the instrument is showing -410 error. This error actually says ' a command was received which sends data to the output buffer, but the ouput buffer contained data from previous command(previous data is not overwritten).The output buffer is cleared when power has been off or after a bus Device Clear.'
What should i do? Can you tell whether what i did is right? I atached the vi which has while loop around the standard event register vi.

Quiz slide waits for Audio to finish before proceeding to next question

Hi guys, hope you can help. I have 5 questions with audio inside narrating the question and the answer in selection. Once you you have chosend your answer then click submit button..it waits until the audio finishes then proceeds to the next question.
hope you can help
Thank you

Having this action on Slide Exit of the Quiz Results slide may not work if the user clicks a button there to Review Quiz because that will mean that the last frame of the Quiz Results slide doesn't get played.
There is an internal Captivate system variable that gets set on each question slide when it's in Review Mode, but I don't think you can read this variable via Advanced Actions. If you could read it, you could check it and then trigger the mute action on Slide Enter of each question slide.
UPDATE: Just thought of another possible workaround. There's a system variable called cpInfoPrevSlide that records the last slide you visited before the current one. You could use this in a conditional action to trigger cpCmndMute. When the user clicks Review Quiz on the Quiz Results slide it will take them back to the first scoring object in the Quiz Scope. OnSlideEnter of this slide you need to check whether or not cpInfoPrevSlide is the Quiz Results slide, and if it is, set cpCmndMute to 1. That should turn off the audio on the slides from then on.
For instruction audio on the Quiz Results slide I prefer to have the audio attached to a rollover caption. That way, the user only gets the audio if they explicitly roll over the HELP button (or whatever you call it).

If reset doesn't work, try and force the iPad into Recovery Mode.
Recovery Mode
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
3.While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.
Note: Data will be lost. You may have to repeat the above many times.

How do I make my program wait for tasks to execute

I want to write a few java classes to do things for me, namely:
1) Create a directory on a local machine which is named to the current date - that I can do with Calendar and String
2) Download the latest committed code from SVN - I suppose I will have to use a process to call SVN from command line. Does Java have a local process caller? I'm familiar with Qt's QProcess, but I'd like to do this with Java.
3) email confirmation that the tasks have executed - I can use javax.mail for that.
If anyone has comments on 2, I'd like to know, please. My greatest concern is how to make sure that steps 1-3 execute sequentially. How do I get that right?

Waiting for Task Manager to close 1 app shows up when I try to restart

Hello,
I am using Windows 8.1 on an HP envy 17. My system hangs almost every time I try to restart it. I have attempted to read the Win 7 related artcles on this topic. However, none of them seem to work. I have attempted a clean boot. I seem to have real trouble
isolating a root cause. I have also checked my BIOS for proper boot order. If anyone has an idea I would certainly appreciate the help. Thank you in advance!

Hi,
What's the app name? Have you gotten chance to get the screenshot of this app?
Did you mean that this issue still persisted in Clean boot mode?
I suggest you scan virus on your computer.
Also, we can make a xperf trace to see the cause:
Using xbootmgr to trace boot, shutdown, and reboot performance issues
http://www.cluberti.com/blog/2011/07/22/using-xbootmgr-to-trace-boot-shutdown-and-reboot-performance-issues/
Use command in this article to collect the shutdown trace:
xbootmgr –trace shutdown -traceFlags BASE+LATENCY+DISK_IO_INIT+DISPATCHER+DRIVERS+FILE_IO+FILE_IO_INIT+NETWORKTRACE+PERF_COUNTER+POWER+PRIORITY+REGISTRY -resultPath C:\Shutdown_Trace
Then post back the etl file under C:\shutdown_trace.

Waiting for Thread to finish execution

I have a program which uses a thread to copy files. While they are copying, a ProgressMonitor comes up displaying the current file being copied. After this has completed, my main program needs to be notified and go on with it's own code. Either I get the 'I'm done waiting!' message instantly, or not at all, instead of getting it after the thread completes. How do I do this?
This is what I currently have
// CLASS 1 //
//...other code is here
myMethod()
ProgressMonitorDemo pmd = new ProgressMonitorDemo();
while (!pmd.isDone())
{ wait(); }
System.out.println( "I'm done waiting!" );
}//Class 2 //

public class ProgressMonitorDemo extends JPanel
public final static int ONE_SECOND = 1000;
private ProgressMonitor progressMonitor;
private Timer timer;
private LongTask task;
public ProgressMonitorDemo()
    task = new LongTask();
    timer = new Timer( ONE_SECOND, new TimerListener() );
    progressMonitor = new ProgressMonitor( this, "Running a Long Task", "", 0, task.getLengthOfTask() );
    progressMonitor.setProgress( 0 );
    progressMonitor.setMillisToDecideToPopup( 2 * ONE_SECOND );
    task.go( );
    timer.start();
public boolean isDone()
    return task.isDone();
   * The actionPerformed method in this class
   * is called each time the Timer "goes off".
class TimerListener implements ActionListener
    public void actionPerformed( ActionEvent evt )
      progressMonitor.setProgress( task.getCurrent() );
      String s = task.getMessage();
      if( s != null )
        progressMonitor.setNote( s );
      if( progressMonitor.isCanceled() || task.isDone() )
        progressMonitor.close();
        task.stop();
        Toolkit.getDefaultToolkit().beep();
        timer.stop();

    return current;

    canceled = true;
    statMessage = null;
   * Called from ProgressBarDemo to find out if the task has completed.
public boolean isDone()
    return done;
   * Returns the most recent status message, or null
   * if there is no current status message.
public String getMessage()
    return statMessage;
   * The actual long running task. This runs in a SwingWorker thread.
class CopyMove
    private String currOldLoc, currNewLoc, type;
    CopyMove()
      while( current < lengthOfTask )
        try
          Thread.sleep( 1000 );
          current += Math.random() * 100; //make some progress
          if( current > lengthOfTask )
            current = lengthOfTask;
          statMessage = "Completed " + current + " out of " + lengthOfTask + ".";
        catch( Exception e )
          System.out.println( "<ERROR>: Long Task " + e.toString() );
}

I tried this but it froze...
public void myMethod()
ProgressMonitorDemo pmd = new ProgressMonitorDemo( );
synchronized( pmd )
   try
     pmd.wait();
   catch(Exception e){}
System.out.println( "I'm done waiting!" );
}Class 2
class CopyMove
private String currOldLoc, currNewLoc, type;
CopyMove()
    while( current < lengthOfTask )
      try
        Thread.sleep( 1000 );
        current += Math.random() * 100; //make some progress
        if( current > lengthOfTask )
          current = lengthOfTask;
        statMessage = "Completed " + current + " out of " + lengthOfTask + ".";
      catch( Exception e )
        System.out.println( "<ERROR>: Long Task " + e.toString() );
    synchronized(this)
      notifyAll();
