Compressor 4.1.3 hangs Waiting for Create Disc to Finish

Compressor 4.1.3 hangs at the "Waiting for Create Disc to Finish" stage. The audio and video streams have been created and are in Finder. The correct drive has been selected in the Actions section and there is a disk in the drive. I have run Compressor Repair. However there is no activity at the drive (which otherwise works fine and will burn a disk from Finder). Anyone any ideas?

I'e not run into this before. Try a different clip – preferably a QuickTime movie. Bring that into Compressor and mark a short section with in and out points. Choose Hard Drive for Output Device in the Job Action section. What happens after you submit it?

Waiting for another script to finish...

I can no more start or stop FMS3 server, it says :
Waiting for another script to finish...
According to the start script, i check
/home/fms/tmp/script.lck and i have this file as empty, what should
i do then ?
Do you all have this file ? /home/fms/tmp/script.lck ?
Jerome

My reply is late i just read your problem after having the same, it locked up my whole Ubuntu system.
Its easy to solve just delete the lock folder you see. Server should restart and work fine.

Application waits for the thread to finish

Hi all,
I have a class let say test that extends Thread.
In my application i say:
test Xtest = new test();
Xtest.start();
System.out.println("Thread finished");
I need my application to wait for the thread to finish for it to continue, i.e. in my example print "Thread finished" .
Can someone help me.
Thanks in advance for your help.
Best regards,
Saadi MONLA

This should work:
test Xtest = new test();
Xtest.start();
Xtest.join();
System.out.println("Thread finished");

Time Machine hang- Waiting for Index to become available (100)

Hi- I'm trying to create a new Time Machine backup to a new external HD (FW800). I've formatted the drive as Mac OS Extended and told TM to use this as the backup drive. I should note that I've done TM backups in the past with a different drive which was a USB2.0 drive, but just got this FW800 and thought it would be much faster to use.
Anyway, now I'm getting the dreaded 'Waiting for Index to become available (100)' message from the TM buddy widget. This keeps repeating every few seconds. I let it run overnight and about 14 hours later, TM backed up 6G from a 150G total. As I watched the backup run, it's copying over about 1M every few minutes. How can this be? I've read through some of the forum entries and I tried placing the external drive in the Spotlight exclusion, and I also uninstalled any traces of Norton that I had installed. Nothing is making this backup go any faster.
So why in the past, has the first backup run fairly quickly, and now this is running like it will take several days to complete?
Please- any help will be greatly appreciated!! thanks.

As far as the communication issue, the external drive mounts just fine, and I can access it in the finder, so I don't believe physical connection is the culprit here.
Not necessarily. A marginal connection may work, but with lots of retries, resulting in things being quite slow. It's fairly rare, but can happen.
I just don't understand why just months ago, the first TM backup started right away and now this is taking forever- Is this a change that was released in an update from Apple in how TM works?
No. In fact, they're supposed to be somewhat faster on Snow Leopard.
How can I delete every trace of previous TM backups and completely start from scratch?
You can erase the drive. If you're going to do that anyway, you might as well reformat it, with the GUID *Partition Map Scheme.* APM should work fine, but if you ever want to use it as a boot drive, GUID is preferred for an Intel Mac.
There's obviously something that's causing this indexing thing to take so long that's never happened in the past.
Try the reformat. (You'll probably have to exclude it from Spotlight again.)
Is it a multi-interface drive? If so, try connecting via USB temporarily.
If that doesn't help, try just copying a large file or folder and see how fast it is. If that's slow, too, you know it isn't Time Machine but something else associated with your F/W card, port, cable, or drive.

JDev 11 hangs - Waiting for Designer to initialize ...

This was working yesterday. The only change is that I updated my system today. I did get new open-jdk libraries. This "shouldn't" be an issue since I put my JDK in .bash_profile as the first entry in the path.
java -version returns:
[klee@laptop ~]$ java -version
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Server VM (build 11.2-b01, mixed mode)
[klee@laptop ~]$
I am running (attempting to run) the Linux version of JDeveloper 11 (11.1.1.0.1). My laptop has 4 GB of memory.
When starting, Jdeveloper has the intial startup, once the screen goes to the IDE, I see the Waiting for Designer to Initialize. The load from java goes from roughly 161% down to 3%, then nothing changes.
Any suggestions besides reload JDeveloeper (I have already done that twice in the last month. That solution is getting old - reminds me of running Windows...
Thanks,
Ken
As a side note, how do you enclose code so it has the nice indentation? the pre tags only seem to work for the first few lines, then the font changes from monospace back to the default. I tried code tags, which just printed code and /code (with less than and greater than brackets) at the beginning and end - didn't do much...

[Solved] systemd does not wait for the unit to finish

My problem is described in the title. I have made a test by enabling the following unit:
[Unit]
Description=/etc/rc.local Compatibility
[Service]
Type=forking
ExecStart=/bin/sleep 1000
TimeoutSec=0
RemainAfterExit=yes
After=network.target
[Install]
WantedBy=multi-user.target
The unit is well started (a process sleep 1000 exists). But with a type=forking, systemd is supposed to hang in this case. Instead, the graphical.target is launched, systemctl list-units mention it as dead, but the display manager is started before the sleep 1000 completes. Ho can I force systemd to wait?
Last edited by olive (2015-03-16 16:49:34)

olive, now you're making even less sense. I didn't say the sleep example was stupid and I didn't question your reasons for doing/wanting this.
I suggested you add "Before=display-manager.service" and you respond "I added Before=graphical.target and it didn't change anything."
I also tried to explain why systemd has no reason to delay the display-manager.service. You could have asked for further clarification, as berbae has now done. Let's try a longer explanation.
Service startup
Services can be started in different ways, as configured with Type=. This determines when a service is considered "started" (or when the service's start-up is considered finished). When a service reaches this state (some time after being started), units that are supposed to start After= this service will be started (and no sooner).
With simple systemd has no further information about the start-up process. It launches whatever you specify in ExecStart and this is the main process that continues to run till the service stops. systemd assumes this type of service is started immediately. All the other types have some way for the process to indicate to systemd (either directly or indirectly) when it has finished starting.
Actually oneshot is also a bit special and that is where RemainAfterExit comes in. For oneshot, systemd waits for the process to exit before it starts any follow-up units (and with multiple ExecStarts I assume it waits for all of them). So that automatically leads to the scheme in berbae's last post. However, with RemainAfterExit, the unit remains active even though the process has exited, so this makes it look more like "normal" service with
begin of unit/startup ---- end of startup ------ end of unit
This is the relevant behavior for this thread. First sleep starts, then after 1000 seconds, start-up finishes and follow-up units will be started. Then either the unit dies, or (with RemainAfterExit) it stays "active".
The man page describes how "end of startup" is determined for each Type.
Targets
Targets are meant to group units together, to provide synchronization points (and replace runlevels). When you start a target, all its units will be started (in parallel if possible). The man page says:
Unless DefaultDependencies= is set to false, target units will
implicitly complement all configured dependencies of type Wants=,
Requires=, RequiresOverridable= with dependencies of type After= if the
units in question also have DefaultDependencies=true.
This means that (by default) when a target is requested, all it units are started first. Only after all units have finished starting, the target itself will be started (and since the target doesn't do anything by itself, this startup is basically instantaneous). Without this dependency, the order between the target and its units is unspecified, so in theory the target could finish starting immediately while its units are still being started.
Back to olive
graphical.target has these DefaultDependencies, so it is not started until all its units (like display-manager.service) and other After= dependencies (like multi-user.target) have finished starting. Your sleep service has to be started before multi-user.target starts (again due to default target dependencies). So first display-manager and the sleep service are started and after 1000 seconds, the sleep service finishes starting and then (assuming all other dependencies were quicker) multi-user.target is started and graphical.target as well (assuming display-manager didn't need 1000 seconds).
If you want display-manager.service after the sleep service, add a Before/After line to specify that (this was your original goal and my suggestion).
olive wrote wrote:However, units that are parts of the graphical target are still launched before the graphical target become active. I am still unable to completely delay the starts of the graphical target before a specific unit completes.
It should be clear now how this works. "units that are part of the graphical target" can only mean "units that are wanted/required by the graphical target" but that is basically all the units that are started when you boot your system, because multi-user.target is a part of graphical.target. And your sleep service is a part of multi-user.target, so in fact you're saying you want to delay starting the sleep service until the sleep service completes
What you probably intended was to delay all units that are a part of graphical.target but not of multi-user.target until after the sleep service. I can't think of an easy (or even good) way to do this and this post is already too long, so I'll table that for now.

DBMS_SCHEDULER wait for job/program to finish

Hello All,
I've run into a little limitation on my understanding of DBMS_SCHEDULER.
I have an executable script which does a network scan. My goal is to lauch this from an application, and wait (could be 5 minutes or 2 hours) for the scan to finish before I return the results.
Where I'm a little confused, is the flow of the entire process works when I want to wait for the program to complete:
1 - Define a program?
2 - Apply arguments?
3 - Apply credentials
4 - Define a chain?
Literally, I'm not sure how to tackle this task. I simply wish to launch to job and wait for it to finish before I go retreive the file from the server. This is what I have so far, just bits and pieces.
Mayeb I simply missed somethign in the docs, and I'm overcomplicate things.
Thanks in advance to the community for you assistance.

Hi Again,
I wrote a sample class to test the connection and my select statement and I was able to reproduce it outside the application. This class has no update at all and it never returns (hangs at iteration number 7 for the first loop).... Another test (removing timeout set which I think it is not related) shows that it stops at Iteration 4 breaking limit 40 (so it is random).. Also, I tried with TRANSACTION_SERIALIZABLE and got same behavior . THIS does NOT happen with db2 driver using same sample.. Please help!!

Waiting for a thread to finish

I've been researching this issue for a couple of days, but I dont think I know enough about threading to ask the right question in a search engine. Sorry if this is a basic blunder....I dont write swing often and it shows.
I have a swing app that includes a long task so I have implemented a progress bar. I need to wait until the progress bar task completes before continuing to the rest of the method. I've tried:
1. Putting the progress bar within a while loop (while task not complete...) but the progress bar dialog does not render fully. I've even added repaint, but still the dialog looks blank.
2. SwingUtilities.invokeLater, but it doesnt wait until the progress bar is finished
3. SwingUtilities.invokeAndWait, though after all the reading I did about deadlock conditions I didnt like the idea. However I was desperate so I tried it and got an error:"Cannot call invokeAndWait from the event dispatcher thread".
4. Putting the code that needs to occur after the progress bar in an "invokeLater" thread
5. I've also used the ProgressBarDemo from the java.sun example with the swingworker hoping the worker thread would handle the issue.
A much smaller version of the code is below:

Asynchronous Call - collect values without waiting for sub VI to finish executing

Hi All, I'm relatively new to LabVIEW and for the first time I'm attempting to make use of Asynchronous calls in a program.
What I would like to accomplish, generally, is this: At the beginning of the main vi, begin running a sub-vi in the background. This sub-vi is collecting streaming data from an instrument with a refresh rate of 50Hz. At various points in the main vi I would like to call the instantaneous value of that streaming data from the sub vi, passing it back into the main vi, while allowing the sub-vi (the streaming data collection) to continue running. The reason for this, is that I need to collect the data from this instrument many times wihtin a loop, and the connection initialization to the streamin data instrument is both slow and faulty, and takes too long if I have to initialize the connection, collect the data, close the connection, each time I wish to collect the data. I would prefer to initialize the connection once at the beginning, have a stream of continuous data being collected in the background, and then at certain points within the main vi loop, query that streaming data for its instantaneous value, but allow the streaming data sub vi to continue running.
I recognize that a method to allow the streaming data collection sub vi to run in the background is to use the Asynchronous call method - however, to collect the data I need to use an asynchronous wait, which will only collect the data if the streaming data sub vi finishes executing. How can I collect the data at a particular instant while still allowing the subvi to keep running (thereby minimizing the number of times the connection to the instrument needs to initialized)?
Any suggestions or alternative methods would be great!
Thanks
Jason

This is typically solved in a different way than what you envision. Have your parallel deamon post its current values to a buffer. This could be a global variable (gasp!!) or an intelligent global variable (a VI with loop that executes always once and has an unitialized shift register that can either be initized or read based on a control input). You can add extra code to the read and write selection such as scaling etc to turn the intelligent global into an action engine that does extra things on its different methods.

I downloaded my Adobe Creative Suite 5.5 design standard, student and teacher licensing and it load ed. I am waiting for an email to finish up but I have not received it yet, I had the serial number entered in and everything should have been good to go.

I downloaded my Creative Suite 5.5 student teacher licensing software. I all loaded fine in my Mac but at the end of the download it gave me a message that I would need to check my e-mail for further steps in order to be able to use the software. I have not received this e-mail yet. I had my email listed as <Removed by Moderator>
Is there something that I need to show as proof of being a student yet? I had to give my student id number in order to get the serial number. I did not use my student e-mail address though. If that is the issue I can supply that also. <Removed by Moderator>
Help. Please

Parent class not waiting for child class to finish

hi,
i have class a and method x in class a which calls class b. its fine till there. but before my class b's action is completed, in which i have to choose a file and display those files in jtable, the remaining lines in method x getting executed. what do you think the problem is.
i.e. my parent's class method is completely getting executed before the child class (frame) returns the result and is closed. where do u think the problem.
please help.

i dont know if i made myself clear. i am giving my code below.
class A{
btnClick{
pnlProductsImport _pnlProductsImport=new pnlProductsImport(dataSource,config,parent,importFile);
_pnlProductsImport.setVisible(true);
_pnlProductsImport.show();
getProducts()
here its showing my pnlProductsImport class screen and before I close that screen, getProducts method is getting executed. as I know, the control passes from class A to pnlProductsImport at show() and when its closed, it will execute remaning lines i.e getProducts, but in this case, it shows the subclass, and immedietly, executing remaining lines. but its also fact that my subclass (pnlProductsImport) implements Runnable, but thread starts only after some time when I click on one of the buttons on the screen.... and i want that getProducts() method to execute only when subclass closes completely.
thanks

Seconds waiting for Loading to be finished.

I asked a guy from Apple Netherlands this week if it was normal that Aperture spends about 5 seconds loading an image after it has been selected. He said I should ask other users with similar configurations to compare because he did not know. Well, here I am.
There is no delay in the images to appear in the viewer or anything, but it takes seconds before I can make edits (using the palettes). Caching seems to be improved between 1.1.1 and 1.1.2 so that a much larger number of images that have been allowed to fully load earlier, don't need to load again when selected.
Is this 'normal' behaviour or is there anything wrong with my machine (2.0GHz G5 DP - 2.5GB RAM - X800) or perhaps anything to tweek to get a speed boast?

Unhappily, this is completely normal with Aperture. (It would be even worse if you didn't have the X800 card.)

Getting a JFrame to display from a JSP, remaining JSP code waits for frame

Hello,
I'm new to Java and just started using JSPs. My objective is to call a display window (from a JSP) that shows the user a list of project selections. Once the user has made their selections and clicked a Submit button, the display class captures the selected projects to the request object as an attribute and then closes the window. The next command in the jsp then forwards the request attribute to a controller. I'm having trouble getting the display window to show-the JSP seems to hang and then timeout. Is there code I'm missing to get the JSP to stop processing while it waits for the choices to be made in the JFrame?
Below is the JSP code and the class I'm calling. I'm seeing all my debug System.out statements but no JFrame pops up. In the JFrame class, the line f.addWindowListener(... does the capture of user selections to the request attribute.
Any help will be greatly appreciated!!
JSP:
<%@ page language="java" contentType="text/html;charset=UTF-8" import="com.plumtree.remote.portlet.*,edu.app.projects.*" %>
<%
    request.setAttribute("action", "prefDisplay");
    request.setAttribute("orderby", "title");
    ServletContext jc = getServletContext();
    DualListBox dual = new DualListBox(request,(String)jc.getAttribute("db.driver"), (String)jc.getAttribute("db.connectionstring"),"title");
     JFrame f = dual.getFrame();
     f.setVisible(true);//expect code to stop here and display frame, waiting for the user to finish.
        //Debug code that tests if frame is visible at this point -came true though did not see Jframe displayed
     if(f.isShowing()){
     System.out.println("Jframe visible");}
       //Send to ProjectsController
      request.getRequestDispatcher("pc").forward(request, response);%>               ---------------------------------------------------------------------------------------------

Hmm, I was trying to avoid writing an applet. Seems my only other option then is to write a JSP that returns a javascript menu populated by options from a database call. Then I'd have the user click submit to send the options to another JSP that simply sets the request attribute and forwards to the controller. Will this be a sound alternative?
