Clear event queue

Hi folks,
This is probably very easy but I haven't found an elegant solution:
I have some variable 'eventtrigger' change a couple of times a second. After running my program for a while - 'eventtrigger' has already been updated a couple of times - I start a subroutine which listens to 'eventtrigger' in an event structure. The problem is that all the updates of 'eventtrigger' that occurred before the subroutine was started are queued up, and so I'm not triggering on what's happening now but on outdated stuff.
So far I clear the event queue by having a do-nothing-but-trigger event structure triggered by 'eventtrigger' in a while loop, plus a timeout event that is just a bit shorter than it takes for 'eventtrigger' to be updated. I stop that while loop when there is a timeout event.
Surely there must be a better way to clear the events that happened before?
Cheers,
WEnte.

I typically compare the actual value with the value from the event terminal and short out the event if they are not equal.
Here is a quick demo.
I am not sure how to apply it to your situation, because I don't know the details of your code. Still, maybe it can give you some ideas.
How does the event get triggered a few times per second? Is this via signaling properties?

Swing event queue, modal dialogs, event threads, etc...

Hey all,
So I am playing around with the focus manager, swing event thread and event queue, etc. Learned quite a bit. I am also playing around with test automation of our UI, using jfcUnit. I have written a few simple apps to play aorund with record/playback, coding tests, etc. What this thread is about though, is figuring out how modal and non-modal dialogs "take over" the event thread/queue? The reason I ask is, if I put a simple test harness like tool embeded in my app as a separate pop-up modal dialog, and from within it there is a GUI that I can use to select a "Test" to run. Now, when I run this test, jfcUnit needs to run on the main window, not within my non-modal dialog. What I am not sure of, however, is that if by using a non-modal dialog all events will go to the main event thread? I mean, I know if I mouse over my second non-modal frame (spawned from the application frame), that events will trigger for that dialog. I remember reading somewhere that modal dialogs "block" the main event queue, all left over events are given to the newly added event queue (presumably by the modal dialog) and existing left-over events get moved to the event queue. If that is the case, I am curious why events for the "old" queue are moved to the new queue if they were orginally intended for the old queue? I would think a "flush" before adding a new queue would be more appropriate so that the old queue can process all of its intended events.
Now, I am just about to try this, but I am hoping a non-modal pop-up will not interfere with the jfcUnit running the UI of the main window. I am guessing, however, that it might. How are non-modal dialogs handled in terms of events and the event queue? Is it the same as modal dialogs? Or is there no blockage of the mainwindow event queue? If there is no blockage, than any sort of automation based on relative positions to a window may occur on the non-modal dialog, in which case it's best to hide the non-modal dialog during running of these tests.
What are your thoughts, or better yet, knowledge of this topic? A decent explanation from a developer standpoint and not from the API's which dont give some of the more detailed info I am seeking is what I am hoping to get out of this.
Thanks.

Check this out. First, AWTListener has a LOT of
different types you can register it for. I ORd all
them together and when I ran my app, it took almost 30
minutes for it to show up because of the huge stream
of events being spit out via System.out. ...Yes, that doesn't surprise me in the least. There's hundreds of events that are fired around, usually unbeknownst to the user for every little thing. Lots of component and container events, in particular.
Just make sure you OR ( using | not || ) ALL the
"mask" values you want to watch for. That may be why
you aren't seeing anything. When I did all that, and
opened a menu, a ton of events came out.Maybe, I'll try that again, but I did specifically add an ActionEvent mask to get action events, and that should be all I need to get action events on buttons or menu items, and it wasn't getting them for either. It was only getting events on buttons when I used SwingEventMonitor, but not menu items.
So I don't quite understand enough of the underlying event handling. Although, I suspect it could have something to do with the fact that these are Swing components, not AWT components (which their native peers) and it's pretty clear from AbstractButton (or was it DefaultButtonModel) how ActionEvents are fired, and they don't seem to have any connection to the code that deals with AWTListeners.
My problem is that I kinda need a way to catch events without having a listener attached directly. Normally, I would have a listener, but there's this situation whereby an action may be triggered before I can get hold of the component to attach my listener to it. Perhaps I can get mouse press/release and just deal with it that way.
Let me know if you did that and still didn't see what
you were looking for. After playing with this, I am
guessing the main reason for AWTListener is to
register a listener for a specific type of event,
instead of listening to them all, hence avoiding lots
of extra overhead. Then again, the main event
dispatcher must do a decent amount of work to fire off
events to listeners of specific awt event types.Yes, it's definitely that. There's no point in sending events if no one is listening for it, so it does save some time.
You are right, popup menus I think are dialogs, I
don't know for sure, but you can access them via the
JMenu.getPopupMenu() and JMenu.isPopupShowin().
However, I am still not getting my test stuff working
quite right.
Yes, for menu popups. For a JPopupMenu on a right-click on any component (tree or whatever), I had a need to know about that from any arbitrary application (it's this GU testing app I'm working on), and since the popup menu doesn't belong to any component before it's shown, I couldn't necessarily know about it til it was displayed. I managed to use a combination of HierarchyEvents (using an AWTEventListener) and "component added" ContainerEvents. Not a simple matter, but it seems to work well.

How to clear outbound Queue in SXMB_MONI

HI Experts,
Unable to process the file in SXMB_MONI as a result the files are getting strucked with the QUEUE and now how to clear this queues for processsing the file...
and another i have configure the server with 611 client but while executing the client of the server is showing 001 and we didn't observe initially as it is working fine but when we observed now it is found
is this has an impact..
do we need to do any other certain configurations at the Server end..
regards,
Kishore

> There is no URL in SXMB_ADM, how to provide an url there, and even before we didn't get this problem as the files are successfully processsing for the past 3 months in PDN, and now we are getting this problem.
>
Hello,
I have understood your problem but you are not following the steps which we are mentioning here.
For your above problem you need to follow ONLY step no1 & 2 mentioned in the blog since steps are common for acitvating the proxy and thats way you are getting confused that why I am asking you to follow that blog.
In the blog step 1 will simply help you creat the RFC destination.
Step 2 will help you to use the above RFC destinaiton as an url.
In opionion if you resolve this problem first then it will be easier to solve your queue problem.
Please let me know if you need more help/clarification in this regard i will help you.

Error while deleting events from the integration event queue

I am trying to delete all the events from the integration event queue after reading it, like this (this is in Java):
        IntegrationEventWS_DeleteEvents_Input input = new IntegrationEventWS_DeleteEvents_Input();
        input.setDateTime("");
        input.setLastEventId("");
        try {
             ((Default_Binding_IntegrationEventWS)onDemandStub).deleteEvents(input);
        } catch (Exception e) {
             log.error("Deleting events from integration queue failed: ", e);
        }Alas, I get the following error message:
Invalid method parameter(s): 'File Id'(SBL-ODS-50007)What does this mean? What is this mysterious "File Id" it supposedly gets? I don't see it anywhere in the SOAP message I'm sending and it isn't mentioned anywhere in the docs.
Thanks in advance for any input.

Dont keep this attributes null
input.setDateTime(""); //Put a Default Time way in
the past. Ex:"1/1/2000"
input.setLastEventId(""); //pass the eventIdThe documentation states that those two are optional (although they are not nillable, for some reason). I tried to set the date to today, but I got the same result. Since setting a date is supposed to delete all events older than that date, I don't think setting it in the past will delete anything.

Workflow in event queue based on a deleted object

Hi all,
I'm facing a problem with a workflow that goes to the event queue, meanwhile the object is deleted and then the WF is released from the event queue in Error. The WF is based on the BO BUS2032 (sales order).
Here are the steps:
1-Sales order created or changed --> event generated --> WF linked to that event goes to event queue
2-Meanwhile the WF is the event queue waiting to be released, the sales order is deleted
3-The WF is released from the event queue but in ERROR status (this is because the BO instance does not exist anymore)
In this scenario, is there a way to end the WF with CANCELLED status instead of ERROR? is there anyy FM or exit you know ehere I can check if the BO still exists once the WF is released from the event queue?
Thanks!!!!!

Some questions/options:
1) How/why does the WF go into an error exactly? Does it try to complete the first step? What if you put a condition step as a first step in the WF and check whether the object is initial and if it is, then cancel the workflow.
2) How about deleting the event from the queue from some user-exit/badi in the sales order deletion. If I remember correctly the events when queued are in table SWEQUEUE. Probably you can find some function to delete events from the queue. Take a look for example function SWE_EVENT_QUEUE_DELETE to see the idea. Or take a look into transaction SWEAD. There you can delete events from queue. Check what it does and do the same in your code.
3) Is this really a big problem? Are there so many sales orders deleted?
In general I think that the whole event queue seems to many times cause lots of problems (the event queue job disappears, WFs will not get started, and whatever.). I try to avoid using it.

Flush Event Queue doesn't work with "Key up"

Hi,
probably just a simple thing I am missing here. See the attached VI (including SubVI). In case 1 I fetch the Key Up event for ENTER and issue a Value Change on the Stop Button. This results in a check for the string length and in case it is too short brings up a dialog telling you the ID string is too short and brings you back to the ID entry. Unfortunately - when confirming the dialog with ENTER instead of using the mouse on the button theKey Up event fired again and therefore fetched by the Event Structure.
So I thought I just flush all events in the queue. To be sure, I put a time value on the flush function which proceeds AFTER the dialog is completed, so the ENTER Key Up should be deleted as well. Bummer is - it doesn't work. Anyone know why?
I tried as well with the dynamic event, which I unregistered right after the Stop Event is issued in the Key Up case. I then "re"register for the Key Up event at the same time/position as the flush event queue function is positioned now in the VI below. Still no joy.
What is my mistake? Thanks a lot.
Solved!

I don't understand 2 things:
a) Why is the Key up event even fired? It doesn't come from the VI where the event structure resides and to which "Instance" the event is bound (VI->Key up), but from the dialog box (which is a different VI). Unless a calling VI inherits all events from its SubVIs or something like that.
b) Why isn't the event fired by the button in the dialog box discarded as the flush event queue function is supposed to perform?
Because you are slow. Not you personally. But compared to the computer, you just don't stand a chance. So you hit the Enter button on the dialog. That dialog's OK button activates on the key down. So the dialog is long gone by the time you manage to get your finger off of the Enter key. In fact, you loop should be back around to be waiting for an event first. So it is waiting for an event when you finally get your finger off of the button. Hey, we have a Key Up event!
Your current checking for the validity of the id is just flat out annoying. Use the Key Down? event to check for a valid character being entered. Notice the '?' in my choice of event there? That means it is a filter event. This means you can throw away (discard) the character being pressed before the control even sees it. You could also discard if there are already enough characters (Greater Or Equal, not Equal).

Error "Event Queue Overflowed" with the "Write file to Citadel Server"

Hello,
I can import data from a file and I can see the data
in the historical database without troubling.
But I always have this error "Event Queue Overflowed", that don't perturb my data and my application (I have just this boring message).
I have tried many things :
- increasing the size of my input buffer (-> 1.000.000, no change) : I don't think so that it's important because I've tried with a value of 100 and anyway sometimes my application works with this small value of 100.
- increasing the File_location tag size (-> 260). No change.
- My write to Citadel.cfg is in the LabVIEW folder.
Can you help me ?
Thank you.

Continuous event queue ?

Hi,
I'm using LV6.1 and I got a little problem with events. How do I make a continuous event queue for activex component, that means LV will respond every time when mentioned event fires instead of it responds just once. Does anyone have an example ?
Thanks in advance!

It seems silly to even use two loops:
If you require two loops and want to use an event structure (maybe the rest of the code requires it), you can manipulate the event timeout, e.g. as follows.

Terminating Event to Event Queue due to Work Item Lock

I have a dialog workflow task based on an asynchronous method defined with a terminating event. When the user executes the work item, the method generates the terminating event (via a V2 change document) but the work item is enqueued (locked) by the same user (locked when they execute the work item from SBWP) and therefore the terminating event goes into error and is placed in the event queue. The background job which processes the event queue does not redeliver the event so it stays in the event queue and the work item fails to complete. Other than dequeing the work item lock myself with a function call how do I get around this catch 22?

Hello Martin,
Actually, the locking happens whether I have the task as asynchronous or synchronous. The problem is the timing. If the user does not release the lock (by backing out of the dialog which is executed) prior to the terminating event attempting to enqueue and complete the work item then the event goes into error and is inserted into the event queue (and lingers there indefinitely, almost). Another issue with the asynchronous approach is that even if the user backs out of the dialog before the event actually attempts to complete the work item they will still see the work item in the inbox unless they click the refresh button when they get back to the inbox.
I have changed the task to synchronous but here is my scenario and another question.
The process being workflowed is the approval of service entrysheets (similar to an invoice if you are not familiar with External Services). In our process, there are a large number of documents being created and requiring approval by particular approvers. It is a normal scenario for an approver to have, lets say 25 documents in his inbox awaiting approval. It was not practical for him to have to navigate back and forth between his inbox and the approval task screen. Therefore, I give the users the option of (when executing a work item) having all the documents in his in-box (for this particular task) be presented in an approval list screen. They can then do a mass approval of the 25 documents with 1 click and 1 navigation. This list screen is also available to be executed outside workflow via a tcode. So, when the user executes the mass approval (either from the inbox or outside workflow) the work items are terminated via the terminating event assigned to the approval task.
A couple of issues remaining:
1) Given my example of 25 work items (user executes 1 work item from in-box
and I displayed all 25) being approved, when the user returns to the in-box, the 24
items remain in his inbox until he clicks the refresh button since these were not actually "executed" from the workflow engines point of view. However, these were terminated successfully because they were not "locked".
<b>Question:</b> Is there a way (user exit?) to trigger the inbox refresh automatically.
2) Now, the issue with the actual work item which the user executes from the inbox. As I mentioned, the work item is locked as soon as the user executes it and is not released until they back out of the dialog or logoff. So, here is what happens: If the terminating event is sent before the lock is released the event is sent to the event queue. If they then back out back to the in-box, its OK since I put some code in the SWO1 object type program (rememeber, its now synchronous) which will determine if they did the approval/rejection and the work item will complete and the event in the event queue will be deleted the next time the Event Queue Background job runs (it deletes any events for work items already in COMPLETED status). However, lets say they simply log off rather than backing up to the in-box or they don't do anything and are eventually logged off by timeout. In this case the code in the object type program to determine if the approval/rejection was done does not get executed (control does not return to the object type program) and the work item remains in "STARTED" status and remains in the users inbox and the event is in the event queue. So, now we have a work item that should be completed still sitting in the users in-box and the terminating event in the event queue. So the next time the user goes to their inbox the work item is still there. The interesting thing is that though this may be confusing to the user, if they then attempt to execute the work item, they will get a message: "Work item currently being completed by event" (Message SWF_RUN 644) and the event sitting in the event queue gets redelivered and completes the work item. To alleviate this problem I was thinking of adding a call to SAP_WAPI_WORKITEM_COMPLETE in the approval list screen after they do the approval but I'm guessing it wont work since it probably will try to enqueue the work item and it will still be locked.
Hopefully you haven't nodded off reading this rambling note...
Thank you,
Bob

Automatic clearing of queue with HP-LJ4250TN on IPP

After installing my HP LJ4250 network printer over IPP it prints but doesnt automatically clears the printing queue and it holds on pause. I have to manually clear the queue and resume printing everytime. Sometimes when I print a doc of multiple pages it breaks down the print job in different tasks also and I am not able to print a whole document at once without clearing the queue tasks finished and resuming the job.
I installed the printer using CUP and got the driver that came with Mac OS X (10.6.4). Does anyone knows how to resolve this problem?

Unfortunately...same problem exists
I also get a fast message that the printer doesn't support IPP and there after print job accepted. It does print but doesn't empty the queue and sets the printer queue on pause. For a next printing job I have to clear the queue manually and resume printing.
Any more suggestions?

SNMP Traps is not being sent clear event when DB is UP

Test Traps everything else is also coming fine. Listener, Database Errors, down etc are all coming in fine thru' SNMP. SNMP traps and OEM all working ok. Question is for database up event there is no CLEAR event being sent. Is there anything else that needs to be configured?

Hello,
Under interface for specific interface: snmp trap link-status

Also in newer IOS
The snmp-server enable traps snmp [ linkup] [linkdown] form of this command replaces the snmp trap link-status interface configuration mode command.

Workflow Runtime Event Queue Data

Does a script exist to cleanup the runtime data in the WF Event queue's ???

Actually, this can be done automatically by setting the Queue Table retention time. There is DBMS_AQADM.ALTER_QUEUE/ALTER_QUEUE_TABLE API to alter the amount of time processed messages are retained in the queue.

To Clear the Queue

Hai Experts!
Requirement: We are using a RFC Lookup in Message Mapping. When there is any Lookup failure then we stoped the message mapping by throughing an Exception. When there is more number of Lookup failed message then we are facing a block in Queue and futher we cannt continue any message processing.
Atthat time we are mannually clearing the queue and restart the process again.
There is any other way to solve this.Pls guid us.
Regard's
Preethi.

Hi Preethi,
As per my understanding we have to route this messages to seperate queue EOIO. if your messages are getting stucked in Queue when ever the exception occurs you have to manually clear queues..or else the other messages will get piled up in the queue...
Rregards,
Naveen
