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 ?

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.

BEx Analyzer Report error - microsoft office excel is waiting for another

Hi,
I am running a query from BEx Analyzer, it is throwing the error as " microsoft office excel is waiting for another application to complete an ole action "
Here in variable screen, I am trying to give input for the variables, then it is throwing the above error message.

The error message you are receiving means that an Excel macro is waiting for another macro to finish in order to proceed. It is an informational message so you understand why the system is slower than expected.
The solution is on the Microsoft side, see BOJ Note 1201513.
From the MSDN link below, you will see a description of the Display
Alerts Property:
http://msdn.microsoft.com/en-us/library/aa194195(office.10).aspx
DisplayAlerts Property
wdAlertsNone No alerts or message boxes are displayed. If a macro encounters a message box, the default value is chosen and the macro continues.
The Note suggests changing the "Application.DisplayAlerts = False" to "Application.DisplayAlerts = wdAlertsNone"

Waiting for another JSP to end.

document.dados.action = "exists.jsp?familia="+familia;
document.dados.submit();
alert('After ');the problem is that when I execute this peace of code the exists.jsp runs AFTER
alert('After '); this one...
But I wanted to do that alert before this...
I belive the question is: how can I wait in my jsp for another jsp to finish running?
Can you help me?
Thanks in advance.

Here is a link with the monthly fees:

You would be forced to select one of these plans and pay for the actiavtion as well as the first month up front. With the cheapest plan this will be a little over $100.

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");

Microsoft Excel is waiting for another application to complete an Ole actio

When I access Data Manager, I get the error message: "Microsoft Excel is waiting for another application to complete an Ole action." When I click OK, I get another error: "Cannot download the dimension list from server. Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." It never used to happen until recently. I don't know what to tell the IT guys to do. Thanks.

This is a known error in V5. I have had this error at almost every V5 customer.
The following solution (got it from support) solves it permanently.
Changes have to be made to the outlooksoft.config file and the connectionstrings in tblappsetinfo. Be sure to restart the server(s) after applying these changes.
1. In outlooksoft.config file of x:\OutlookSoft\Websrvr\bin folder on the web server change the following line:
<add key="Database_AppServerDBConn" value="Server=<servername>;Database=AppServer;Trusted_Connection=True;"/>
to
<add key="Database_AppServerDBConn" value="Server=<servername>;Database=AppServer;Trusted_Connection=True;pooling=false"/>
Please note that where I have <servername> you should put the name of your server ****
Also, add the pooling=false; to every connection string in tblappsetinfo.
I am sure this helps,
Regards,
Alwin Berkhout

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?

Package deployment keeps getting stuck with message 'Waiting for another program'

Hi, I just started working on SCCM. We have an Orchestrator runbook which creates a collection and then creates an advertisement for packages and task sequences. I was able to get a task sequence and a package successfully execute. When
creating the advertisement, I set it to RERUN_ALWAYS. However, the next time I ran our runbook which creates the collection andadvertisement (I manually deleted the previous one), it does create them but the deployment is stuck to In Progres with the
Description of 'Waiting for another program'. This just happens for packages before and not for task sequences the other day but now, it's the same issue whether I use a package or a task sequence.
I see this in execmgr.log:

yes check the exemgr.log file and also see is that package has dependency for another package? and if yes then that package is already available non DP?

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.

Patched Deployments issue: "waiting for another installation to complete"

I have some percent of computers which runs into above state in monthly patch deployments. I could minimal information from execmgmr, udpatesdeployment.log,
CliSpy and Client Center etc tools but that doesn’t offer much help to nail down the issue completely. Have any of you dealt to resolve such issue successfully ? Is there any efficient way to handle this ?
It seems I have
DeploymentA, waiting for the completion of DeploymentB, which in turn waiting for the completion of
DeploymentC. Is there any better approach I could take to nail down and resolve the issue. One of my finding is, KB articles installs (SCCM R3, SCCM Asset Intelligence) causes these issue as they restart (upgrade sort of execution) the
agent during the execution, I need to confirm these
Vasu

Hi Vasu,
This issue can be caused by a deployment was previously deployed and was now deleted. This was because the clients finished installation
and wanted to notify the Server that it is done, but since the deployment was deleted, it couldn’t Notify its progress to the site server and the CCM_DeploymentTaskEx1 got stuck.
Please use the following scripts to delete the instance to test this issue.
strService = "CcmExec"
strComputer = "."
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\CCM\SoftwareUpdates\DeploymentAgent")
Set colWMISettings = objWMIService.ExecQuery("Select * from CCM_DeploymentTaskEx1")
For Each objWMISetting in colWMISettings
objWMISetting.AssignmentId = ""
objWMISetting.JobId = "{00000000-0000-0000-0000-000000000000}"
objWMISetting.Put_
Next
'Stop service
Set objWMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objService = objWMI.Get("Win32_Service.Name='" & strService & "'")
objService.StopService()

[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.

Whether two session with for update at the same time will wait for another?

Will this scenario happen?
One session executes: select ... for update/select ... for update nowait
The other session also executes: select ... for update/select ... for update nowait
Two sessions happens at the same time unluckily. Whether they will all stand by because of "for update" or quit immediately because of "nowait"?
Thx a lot.

This situation is called 'a deadlock'. Oracle will automaticaly detect a deadlock. One of the statements will fail with ORA-00060 deadlock detected;
No, it's not.
A deadlock is when sesson-A has a lock on something that session-B needs in order to continue, and at the same time, session-B has a lock on something that Session-A needs in order to continue. They BOTH have something the other needs.
In the OP's case, at least as he described it, it is simple serialization. The one with the lower scn will go, then the next.
PS.
Why don't you try? You can setup a small table with some records, open 2 sessions to the same database and for example issue UPDATE statements:
session 1: update where id=1
session 2: update where id=2
session 1: update where id=2 - this will hang waiting for session 2 to commit and free lock
session 2: update where id=1 - ORA-00060
You may also read about deadlocks in chapter on "Data Concurency and Consistency" of "Oracle Concepts'.

VI waiting for another VI finishing before completing

Howdy
i have a goniometer.vi which should move the detectorarm 1°, then starts a spectrometer.vi and measures the spectrum. after completing measurements the goniospectrometer.vi should move another 1° and again...
i have made the spectrometer.vi a sub.vi and wanted to include it into goniometer.vi, but i have no idea how to tell the goniometer.vi that spectrometer.vi is ready for moving on.
thanks
Robert

Use a while loop. Make sure that both subvi's (goniometer and spectrometer) have error in and error out. Call the goniometer vi first and spectrometer second, wire error out from the first to error in of the second. Put some kind of exit condition to stop the loop. The first vi will execute, then when it is done the second will execute. The process will repeat until the stop condition is met.

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.
