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");

[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?

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.

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:

Application waits for a responce from the DB ...

Hi friends,
I have a multi threaded .NET application that interacts with ORACLE 10g DB.
When the multi thread is executing for less than 4hrs continuously there is no problem, but if it continuous execution for more than 5hrs the application doesn't respond.
To track the problem i have followed the standard logging process i.e. to a file. When i analyzed the file i could see the application sending a request to the DB and waits for the reply, but the server doesn't reply.
One thing to be looked in is that the same piece of code was execution for 5hrs.
I have no idea of this behavior, some one please help me out ...

Hi Pierre Forstmann,
I am not a ORACLE DBA expert but managed to get some information,
Error message in database alert log file.

I would like to know what would be the reason that all the 10 session have disappeared from V$SESSION.

They're still working on fixing that Bug - https://bugzilla.mozilla.org/show_bug.cgi?id=608589 - a fix for another Bug - https://bugzilla.mozilla.org/show_bug.cgi?id=613888 - landed earlier this week which might have fixed it. Unless you are willing to install a nightly Trunk which has the latest fixes, you'll have to wait for 4.0b10 for the fix.

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.

Waiting for a thread to die.

Hello, I hope you can help me...
I am writting a jdk1.4.1 Swing application that displays a small animation. This animation is processed from within a separate thread. My program makes a call starting this 'animation thread'. For practical reasons my program needs to wait for this thread to die (and thus the full animation to be shown) before it can continue. I am waiting for the animation thread to die using Threads 'join' method. However the problem with this is that I am forcing the GUI thread to wait resulting in the animation being calculated but not displayed. And so... how can I fix this... all I want is to wait until the animation is shown.
What I would like to do is:
1. Start animation;
2. wait intil animation has completed;
3. continue with program.
Any help or advice will be greatly appreciated.
Thank you in advance.

Maybe this design could work for you. You divide your program into three parts running in three separate threads.
1. The main thread handling GUI stuff and coordination of the two other threads.
2. A working thread doing most of what the main thread is now doing.
3. The animation thread.
With this division of labour the working thread is waiting for the animation thread to finish (the main GUI thread isn't). The main thread will be free at all times to react to the users input or updating the screen or whatever, while the other two threads are cooperating to produce the animation.

Please wait for the group policy client - shutting down issues

Hi
I have issues with shutting down machines. When machine is connected to company's LAN everything works fine. However, if machine is connected to VPN - Juniper NC - 1 hour or more it always hangs when it is shutting down. When I shut down the machine
(verbose mode on), first stage is:
Please wait for the system Event Notification service.
This ends exactly
after 3 minutes. Next stage:
Please wait for the group policy client windows 7
...is never timed out (even after few hours). Machine never shuts down.
In Application logs there are always these 4 events when machine is unsuccessfully shutting down:
6005: The winlogon notification subscriber <Sens> is taking long time to handle the notification event (Logoff).
4627: The COM+ Event System timed out attempting to fire the Logoff method on event class {D5978650-5B9F-11D1-8DD2-00AA004ABD5E} for publisher and subscriber . The subscriber failed to respond within 180 seconds.
The display name of the subscription is "ISensLogon2". The HRESULT was 80010002.
6006: The winlogon notification subscriber <Sens> took 180 second(s) to handle the notification event (Logoff).
6005: The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (Logoff).
Sens is timed out after 3 minutes while there is no 6006 event for GPClient and machine is stuck there for ages (Please wait for the group policy client
stage). I noticed in System logs that machine always hangs if there is this error
5783: The session setup to the Windows NT or Windows 2000 Domain Controller \\server for the domain X is not responsive. The current RPC call from Netlogon on \\machine to \\server has been cancelled.

I tried with signing out from VPN before shutting down machine, I even switched off WiFi but machine still hung. If i tried to get GP results before shutting down machine it takes ages and it is stuck in "Getting the user name" stage.
Gpupdate /force never updates policy (It stops at Updating Policy...). I tired with installing different hotfixes which did not resolve the issue. I never have any
issues with logging in, no GP scripts are applied when user is logging off or on, no roaming profiles. The only issue is when machine needs to be shut down.
I excluded 1 machine from GP and left it on VPN for a few hours, several times. It always shuts down successfully. I applied GP back one by one and the one which is presumably causing an issue is Avecto which adds admin rights when VPN application
starts (event 100):
Process started with admin rights added to token.

I guess there is a DNS issues when machine is on VPN which leads that GP cannot be applied / updated. Not sure if or why Avecto would have an impact on this. When machine is trying to shut down it still somehow thinks it is connected to DC. What
I also noticed are several explorer crashes while machine is on VPN.
Does anyone have same issues? All machines are Dell with Juniper NC (VPN).
Thanks,

Hi,
According to event log, Winlogon process takes a long time to handle logoff event. That's to say winlogon process is waiting for response to logoff.
According to your description after, this problem is most probably caused by Avecto. You can try to disable or uninstall it temporarily for test.
To make further troubleshoot with this problem, you can try to use WPT (Windows Performance Tool) to make troubleshoot.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.<br />
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Waiting for the end of the process

I'm executing a command using the Runtime class and I have to wait until the end of the command to get the results. But, I don't want to sleep the thread for some undeterminated time. I'd like it just to wait until the command ends.
See in this code:
try
String result="";
Process p = Runtime.getRuntime().exec("sh"); //open a new shell
InputStream is = p.getInputStream();
OutputStream os = p.getOutputStream();
os.write("ifconfig -a | grep PROMISC -c\n".getBytes());
os.flush();
try {
Thread.currentThread().sleep(1000);
/*command should take some time to execute so wait for 10 secs .... I don't like this .... I would prefer waiting for the end the command ifconfig*/
catch (InterruptedException eIE) { }
while (is.available() > 0)
result = result + ( (char) is.read());
System.out.println(result);
catch (IOException e) {
System.out.println(e);

AFAIK you can only detect if the shell process has finished, as sub-processes of the shell are not visible to your Java program (without resorting to OS-specific syscalls).
You can write "exit" (or whatever terminates your shell) in the output stream as the last command - this will quit the shell as soon as all commands are finished, and that will be visible to your prog. Note that you should not run ANY of the shell commands in background then, as this could cause the shell to exit before the commands are finished (and, depending on the system, even signal the subprocesses).

Waiting on unknown threads to finish

I have made the ExecutionService class, and now i have a small problem. The point of the class was to split the job normally done by one thread into as many as possible. Now, i need the thread that called executeInstantly/waitToExecute to wait until the requested task(s) are done, and there are no more tasks to process. What would be the best way to implement that? Note, only one thread will be adding to the Queue of tasks, and its the same one that needs to wait on them to finish.

You would use a java.util.CountDownLatch if you only wanted to wait for the tasks currently executing and waiting in the queue (for example, there would be no tasks added AFTER the waiting began). I think this is suitable for your situation since you said there would be just one thread adding to the queue.
Pseudocode:
class ExecutorService {
    private volatile CountDownLatch counter = new CountDownLatch(Integer.MAX_VALUE); //start countdown latch at really high values
    private AtomicInteger activeThreadCount = new AtomicInteger(0); //keep track of threads actually working
    private BlockingQueue queue; //keep waiting tasks
    class PermTask implements Runnable
        public void run()
            while (!shutdown)
                Runnable task = queue.take();
                activeThreadCount.incrementAndGet();
                try
                    taskToRun.run();
                finally
                    activeThreadCount.decrementAndGet();
                    counter.countDown();
    public void waitForTasksToComplete()
        int totalTasks = queue.size() + activeThreadCount.get();
        counter = new CountDownLatch(totalTasks);
        counter.await();
    }This would take a bit of cleaning up, for instance you have to protect the activeThreadCount and the counter so that the values don't change in the middle of some work (a ReadWriteReentrantLock might work nicely here - the PermTask would acquire Read Locks so they don't block each other. The wait... method acquires a Write lock to it waits for Reads to finish, and blocks more Reads until it is done). But it should get you started.

Error during creation of application entity for the plug-in.

Hi Experts,
As part of creating Content Database source for SES....
We,
1 Activated the Oracle Internet Directory identity plug-in for the Oracle Content
Database instance.
2) However after activating Identity plug-in for Oracle Internet Directory.... ......... we used the csPlugin.ldif file to create an application entity for the plug-in by running the following command "$ORACLE_HOME/bin/ldapmodify -h oidHost -p OIDPortNumber -D "cn=oracle" -w password -f csPlugin.ldif" ....but in the process executing the above command.... getting the following error(we gave correct login details):
SASL/DIGEST-MD5 authentication started
ldap_sasl_interactive_bind_s: Invalid credentials (49)
How can i resolve this.
I have another query...in the command "$ORACLE_HOME/bin/ldapmodify -h oidHost -p OIDPortNumber -D "cn=oracle" -w password -f csPlugin.ldif" which user name should i specify..... is it "cn=oracle" or "cn=orcladmin"
Thanks
peter.

Hi Raford,

We have followed the installation details provided in "SESAdmiistratorGuide".
In that guide.... during creation of Content Database source he did not mention any entry for "SES keystore location", and the exception which we are getting is related to "SES keystore location: null" (please look into the exception stack).
could you please guide us.
Thanks
peter.
