Does JVM clean up after a scheduled thread has finished its task?

If a Timer class is scheduled to perform a certain task repeatedly, and when a scheduled task is finished, who will clean up or terminate or stop that thread? Is there anything that I can do to make sure those finished threads are cleaned up so that they will not occupy resources.

Further for java.util.Timer, at least in Java 6:
"After the last live reference to a Timer object goes away and all outstanding tasks have completed execution, the timer's task execution thread terminates gracefully (and becomes subject to garbage collection). However, this can take arbitrarily long to occur. By default, the task execution thread does not run as a daemon thread, so it is capable of keeping an application from terminating. If a caller wants to terminate a timer's task execution thread rapidly, the caller should invoke the timer's cancel method."
Not sure if this self-cleanup goes back to 1.4 though.

How to find out if a thread has finished execution?

Hi, Am new to multi-threaded programming. I have a question: I start a new thread from the main thread. This new thread has to update a swing component & thats it. How do I know when the new thread has finished its execution? Also, I need to kill the thread once it finishes its execution?..or will Java's GC take care of it? If I need to kill it from the code, how do I do it? I see that the destry() method of Thread class is deprecated.
Thanks.

boolean isAlive()
Also, I need to kill the thread once it finishes its execution?..No
or will Java's GC take care of it? Yes
You can do Thread.join.
See the API docs and/or a threads primer.

Hi Henryhippo,
If you have questions about play order in iTunes, you may find the following article helpful; I believe you can use the Play Next or Add to Up Next to add albums as well as songs.

Scheduled job does not stop even after the scheduling window closes

We have written custom stats gathering job whose duration has been set as 14 hours in the schedule. This job starts daily at 6:00 PM and expected to complete upto 8:00 AM next day. But the problem is that this job continues to execute even after 14 hours. If we look at the dba_scheduler_job_run_details table, then its execution duration is about 16 - 19 hours daily. We could not understand as why it is not closed when scheduling window closes? Is there any problem with the scheduler configuration?

Straight out of the docs 83 DBMS_SCHEDULER
stop_on_window_close
This attribute only applies if the schedule of a job is a window or a window group. Setting this attribute to TRUE implies that the job should be stopped once the associated window is closed. The job is stopped using the stop_job procedure with force set to FALSE.
Having said that, stop_job with force applies to whether information about the job is gathered - you would have to test, but I believe that the statistics gather will be terminated in the middle of whatever it's doing.
Update: force says:
force
If force is set to FALSE, the Scheduler tries to gracefully stop the job using an interrupt mechanism. This method gives control back to the slave process, which can update the status of the job in the job queue to stopped. If this fails, an error is returned.
If force is set to TRUE, the Scheduler will immediately terminate the job slave. Oracle recommends that STOP_JOB with force set to TRUE be used only after a STOP_JOBwith force set to FALSE has failed.

How do i connect to a wifi network after my time capsule has completed its auto setup.

Let me start by saying I contract overseas currently in Afghanistan. Ok so I have over 10 networks in my area and can not connect to a router with ethernet cable. When it does the auto setup it finds the network sometimes but doesn't stay up long enough for me to enter my password. I just dont know how or where to manually set up my network. I also dont know what information i need. I dont have access to any of the routers so this might not even be possible.
Thanks Dan

Unfortunately, the Time Capsule, and AirPort Extreme do require an Ethernet connection when they are connected to a 3rd party wireless network.
It is a bit goofy....and I don't know if it will work in your particular situation.....but here is what I do when am traveling and I want to set up a private wireless network in my room......and the hotel only provides a wireless connection. I travel with an AirPort Express and another AirPort router....two devices.
One AirPort Express is configured to "Join a wireless network", so it receives the wireless signal from the hotel. That same Express then feeds an Ethernet signal from its LAN port to the WAN port on another AirPort router, which is set up to "create a wireless network".
So, I can set up my own private network in the room and connect from multiple devices....wireless or wired...and only pay for one connection.

How to call a javascript method after the PPR event has finished ?

Hi!
How can we make a javascript method get called after the processing of ADF PPR event?
My specific use case is,
I want to call a javascript function after the data in the table is loaded...
In 10g, that is not a problem, as the data used to get loaded directly during onLoad, and so i would call my js function on load;
but in 11g , the table data is being loaded through PPR which is initiated onload, and so i needed to call my function after the PPR Response processing has been done; for which I need the name of the event triggered at that instance.
Is it possible to do this?
Regards,
Samba

Hey, I got it.
I handled the ADF Controller's PREPARE_RENDER_ID phase of the lifecycle, and then called the
script to get Executed.
The code :
    public void afterPhase(PagePhaseEvent pagePhaseEvent) {
        FacesPageLifecycleContext ctx = (FacesPageLifecycleContext)pagePhaseEvent.getLifecycleContext();
             if (pagePhaseEvent.getPhaseId() == Lifecycle.PREPARE_RENDER_ID) {
                if(AdfFacesContext.getCurrentInstance().isPostback() )
                    afterRender();
    }is written in lifecycle listener , and my backing bean extended this listener ,
and in the afterRender() method I did this :
   public void afterRender(){
            System.out.println("AFTER RENDER CALLED");
           FacesContext context = FacesContext.getCurrentInstance();
           ExtendedRenderKitService service = (ExtendedRenderKitService)Service.getRenderKitService(context, ExtendedRenderKitService.class);
           service.addScript(context, "translate();");
       }That's it.
It did work, magnificently.
Thanks for the idea.

ORB does not perform clean up after destroy() is called.

hi,
the HelloClient example (POA model) which is provided in the Java IDL tutorials, does not perform clean up after the execution is complete.
i.e. i can still find the Socket descriptors in the file system under the path (/proc/p_id/fd). Do we need to explicitly destroy the sockets inorder to perform the required clean up??the OS i'm using is Linux.
if yes, then how do i do that.... the following are the steps to reproduce the problem:
1)start HelloServer
2)start HelloClient
3)check file count in /proc/process_id/fd before calling init.
4)invoke ORB.destroy() method.
5)check file count in /proc/process-id/fd after destroy completes.I have included Thread.sleep(25000) inorder to check the file count dynamically at each stage of execution.
Any help in this regard is welcome....!!
thanks in advance

Hello:
This reply may be long after the time that you need it ... but the problem
that you are experiencing sounds very much like a bug that was fixed in the J2SE 1.5.0_10 release.
It is bug 6354718 ....
In the evaluation section of that bug they note:
Yes. It's a known bug in ORB connection management. What's happening here is, the connectionCache that maintains both inbound and outbound connections does not reclaim connections, upon ORB destroy() call. There is a connection reclaim() logic in place, but does not kick in, until it reaches certain watermark levels. Since, a single client can have a multiple ORBs and thereby multiple outbound connections (in the reported case) , with each cache having exactly one connection which leaks up on ORB exit. This leak multiplies based on the number of ORBs and time period over which client stays live, up and running.
The solution is, to walk through the connection cache and close each connection,
no matter what the watermark levels are. This can be done at the corba transport manager close() call.
Note: In the above evaluation they tell you how to fix it yourself but I believe (I haven't tested it yet ....) that if you upgrade to JDK 1.5.0_10, you should find that it has been fixed for you.
I hope that I'm not steering you wrong, but that's my take on your situation.

How do I import my address book after doing a clean install of Leopard?

I just finished doing a clean install of Leopard and I realized that I forgot to export an Address book archive before erasing my hard drive. I still have all the Address Book files stored in Application Support in my Library (on my backup hard drive) but I don't know how to get those files into Address Book. Whenever I try the different import options they are all grayed out.
I also have the Address Book files stored on my iPod Touch but syncing with my Touch doesn't seem to bring them into my computer. Is there anything I can do at this point besides entering them in one at a time?! Copying and pasting the files from the backup to the current folder doesn't seem to do any good either. It will tell me that the files I am trying to write over and in use. It says this even after I close Address Book.

Ok, I got is to work by selecting the folder itself and copying it over. Aparently it does work if you open the folder, select all the contents and then paste it. I didn't think it would matter which way you did it.

How does WebLogic clean up stuck threads?

Hi,
Using WebLogic 9.2.2 on Linux OS. In our logs, we are finding some stuck threads and it seems to be due to something WebLogic is doing. While we don't understand the cause (maybe the stack trace helps), does WebLogic do anything to remove stuck threads from its pool, or is there anything we can do to configure it to?

You can configure these actions to occur when not all threads are stuck, but the number of stuck threads have exceeded a configured threshold:
* Shut down the Work Manager if it has stuck threads. A Work Manager that is shut down will refuse new work and reject existing work in
the queue by sending a rejection message. In a cluster, clustered clients will fail over to another cluster member.
* Shut down the application if there are stuck threads in the application. The application is shutdown by bringing it into admin mode. All
Work Managers belonging to the application are shut down, and behave as described above.
* Mark the server instance as failed and shut it down it down if there are stuck threads in the server. In a cluster, clustered clients that
are connected or attempting to connect will fail over to another cluster member.

Same thing happens when i click restart.
No difference when i run it in Safe mode. And it won't let me create a new profile either. Is there anyway else i can extract my bookmarks? This is driving me crazy!

Did the crash reporter send any crash reports? 
You can see the crash reports in this folder:
"C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Crash Reports"
See: http://kb.mozillazine.org/Breakpad
See also [[Firefox crashes when you open it]]
Create a new profile as a test to check if your current profile is causing the problems. 
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]] 
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" 
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) 
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox 
If that still causes the same problem then do a clean reinstall and remove the Firefox program folder.
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

***Everything else seems fine

I have a MacBook pro version 10.6.7 with snow leopard. After an scheduled software upgrade I could not open Quicken (It said it could not open the files). Now I can only open it if I have my external drive on. Can you help?

I have a MacBook pro version 10.6.7 with snow leopard. After an scheduled software upgrade I could not open Quicken (It said it could not open the files). Now I can only open it if I have my external drive on. Can you help?
All the information that I had input on Quicken is gone. I have to have the external hard drive that I use to back up to be able to use quicken now. It is as if it was erased from the laptop hardrive

Try repairing permissions. My favorite way is with a utility called AppleJack. Info and download here. It's free. It only works when you boot in Single User Mode. When restarting or booting, hold down the Command key and S keys.
You will get a very different startup screen that looks like the Terminal app has hijacked the screen. Just let the lines of text scroll by. When that happens you will get a text entry prompt. Type in "AppleJack" without the quotation marks.
A DOS looking menu will appear. Choose 1 or d to run Disk Repair. If you get a message that Disk Repair found and corrected errors, run it again. Repeat until you get the "your disk appears to be ok" message. This rarely happens with my experience, though. This does the same thing as as booting from an external drive and running Disk Utility's repair. Only, no external drive is required!
Next, choose 2 or p to repair disk permissions. This will take a little while. AppleJack warns that it will take up to an half hour to run repair permissions. It'n never taken more than about ten minutes for my MacBook Pro.
As permissions are repaired, you will see each repair scroll on the screen. When done, the menu returns, choose q to quit. Then at the prompt, enter "exit" without the quotes. Your MacBook Pro should restart into Mac OS normally after this.
Hope this helps.

MBP does not come back after hybernation

Hello everyone,
I am enjoying my MBP except for one problem. It does not come back after it hybernates sometimes.
I hit a key, hear the superdrive do it's "thing" and then after much waiting (approximately over 10 minutes) no picture or video on the screen!
I can tell that it's still powered on because it's plugged in and when I hit the Caps Lock key it lights on and off.
The only way that I can get it out of this state is to hold down the power button, unplug the power cord, take the battery out, hold in the power button for 4 seconds, reinsert the battery and power back on.
I have to then cycle the power back off because the first time it does not come back but I just get the blank white boot screen and no 'apple'.
When I turn it back on the second time, it boots up.
Anyone else have a problem with this?
Thanks for listening!
Mark

Hello Gweedo!
Yeah I have the same issue and am up to date. Apparently this is a pretty huge problem with the Macbook Pro since the last Graphics update after updating to 10.5.2.
http://discussions.apple.com/thread.jspa?threadID=1394449
I have been perusing through that topic and hopefully they will come up with a fix for this.
The only work-a-round that I have found (but haven't tested extensively yet) is to disconnect to the wireless, turn off blue tooth, disconnect my external monitor and then go into sleep mode. Then it always comes back. But if I leave it connected to the wireless, bluetooth, and external monitor - it's a crap shoot as to weather or not it will come back up.
This is pretty frustrating because half of using a laptop is being able to hybernate and sleep properly.
I even have the 'smartsleep' installed.
Thanks for commenting everybody!

Clean up after each system upgrade

Hi,
After each upgrade my system increase its disk usage.
I type "pacman -Qet", and there is a lot of packets, but I'm not sure is it safe to delete them.
Which is the best rule to follow about cleaning the system, using pacman?

How will you know if it's needed for anything if you have no idea what that package does?
An example: what does 'git' do and why do I have it installed? Pacman shows it's not required by any package. Ah, I'm accessing some git repositories - that's why I have it installed.
You have only a couple hundred packages installed, so 'pacman -Qi <packagename>' away :-)
'pacman -Sc' should be enough to get rid of old & unneeded packages.

Does JVM clean up after a scheduled thread has finished its task?
