AsyncEventListener receive duplicate events

Hello

I'm running a problem with some AsyncEventListeners who receive duplicate events. There are four tables with listeners (the listener code is the same for everyone).

When a row is inserted in one of the tables there are four events in double received by the listener of the table (I checked this by writing instructions for debugging in a file).

Here are the instructions to create the table:

create table sqlfire.proxy_0

(integer k, value varchar (500))

GROUPS of SERVERS ASYNCEVENTLISTENER ("proxy_0") (proxy_0)

;

create table sqlfire.proxy_1

(integer k, value varchar (500))

GROUPS of SERVERS ASYNCEVENTLISTENER ("proxy_1") (proxy_1)

;

create table sqlfire.proxy_2

(integer k, value varchar (500))

GROUPS of SERVERS ASYNCEVENTLISTENER ("proxy_2") (proxy_2)

;

create table sqlfire.proxy_3

(integer k, value varchar (500))

GROUPS of SERVERS ASYNCEVENTLISTENER ("proxy_3") (proxy_3)

;

Here are the instructions that add each AsyncEventListener:

CALL THE SYS. ADD_ASYNC_EVENT_LISTENER (' / taq_us | username = gpadmin | password = gpadmin | tableName = lineitem "");

CALL THE SYS. ADD_ASYNC_EVENT_LISTENER (' / taq_us | username = gpadmin | password = gpadmin | tableName = lineitem "");

CALL THE SYS. ADD_ASYNC_EVENT_LISTENER (' / taq_us | username = gpadmin | password = gpadmin | tableName = lineitem "");

CALL THE SYS. ADD_ASYNC_EVENT_LISTENER (' / taq_us | username = gpadmin | password = gpadmin | tableName = lineitem "");

I have attached the code AscynEventListener (MicroBatchListener.java).

For any help or suggestion would be greatly appreciated.

Thank you

Hi Sean,.

SYS. ADD_LISTENER is unchanged and still supported in 1.0.2. It should work without any problems even in older versions.

  • Receiver output events 8 to CVI exit 7

    Hi all, I am facing a strange behavior when you change an old program written in CVI 7.1. CVI 8.5 is installed on my machine, so the active execution engine is one of the most recent version.

    If you change the program in CVI 7 IDE, I found that a table receives events still undefined in this version. Specifically, it receives a EVENT_MOUSE_POINTER_MOVE event when the mouse points control; I also noted an EVENT_LEFT_CLICK_UP event. I did not the specific tests for other events.

    He is an annoying problem with a simple solution: just by adding the line

    If (event > EVENT_MARK_STATE_CHANGE) return 0;

    at the beginning of the function removes any possible confusion due to unexpected events; reception of events in the IDE, both in the compiled application.

    Having noticed this fact, there are two issues I'd like someone can answer:

    Q1: is this expected behavior? In other words, the events are coded inside the runtime engine so that I have to consider my controls will receive the events mentioned in the TEN running? I wonder if I need to add the output line of filtering on all programs that are likely to be running the RTEs more recent than the version that they were built with: in other words, the compatibility declared with new RTEs could lead to unpredictable behavior.

    Q2: is this consistentbehavior? In other words, I can rely on these events passed to the controls exactly as if the application was developed in the more recent IDE?

    Yes, this is the expected behavior. I realize that the reminder to receive new events when you install a new version of the CVI is probably not an obvious side effect, but it's a side effect of the architecture of the CVI runtime engine. As mentioned by jr_2005, that is why it is important to respond only to specific events in your reminder. As mentioned by ebalci, you can work around this by using a local RTE by copying the version of this editor, you want your application to use in the same directory as the executable file.

    However, if the recall does respond to specific events, this behavior should be no problem. As you have noted, it is only when you have the code in an event of default, or outside the switch statement, as it can cause unexpected results.

  • We recently had Comcast to att uverse & changed our settings in outlook express but now receive duplicate emails

    Outlook express duplicate messages

    We recently had Comcast to att uverse & changed our settings in outlook express but now receive duplicate e-mail messages.  I have leave copy on the server checked so that we can access our messages from multiple computers, do not know if there is anything else that needs to be changed to avoid this problem.

    Pretty much confirms that it is outside interference. You have McAfee on both machines? Close all programs and temporarily disable McAfee on both machines. Send a short test message now.

    Norton and McAfee are two of the worst programs to use with Windows e-mail clients. They cause conflicts and must be removed in favour of a less intrusive program like NOD32, (not free), Avast or Microsoft Security Essentials, (both free). I use MSE on all my machines and it works fine.

  • GlobalEventListener received an event twice

    Hi all

    I use the GlobalEventListener to receive an event. However I just send the event once, but I have the event twice in the eventOccurred() can someone help?

    I would almost bet money on the fact that you have saved the two listeners.  Make sure that you really only a single listener.

  • Need help: receiving duplicate service Eloqua App Cloud Action notice

    We have developed an application using the eloqua action service & have notification service configured in a way to our web hook and it works fine, it send a notification to our service once the campaign is activated & send us all records of contacts, but we receive duplicate notification.

    • We receive lots of contact as notification POST records in batch of 5000 but we receive notifications, duplicate & same batch of documents several times
    • hasMore flag is supposed to tell us if they had more records, but it is still as fake and we continue receiving duplicate notifications.

    Looks like that issue an eloqua https://community.oracle.com/message/12866151, please help.

    Thanks TJ fields-Oracle

    Here is the solution,

    • You must reply with a response of 200 level or Eloqua will continue to scream assuming you never received & keep sending multiple opinions until it times out at the end fix this problem resolved by the issue of duplicate notification.
    • and now that my process to receive data directly from eloqua as part of the notification service will not use the bulk import value in hasMore flag is not serious.
  • Image with enabled set to false still receives click events

    I have a simple image with a click event and the button is set to enabled = false and it still receives click events. Does anyone know how to disable the image if it receives no click events. I want only the image to send a click on some points, then the other event not to do... Thanks to all those who can help

    I didn't think allowed aims to control the actual events - rather the native behavior resulting from events. My suggestion is that you either remove the headphones when you don't want to see the clicks, or place the code in the listener that runs the effect selectively.

    If you want you could simply encapsulate your headset with a test for the license:

    private void handleImageClick(event:MouseEvent):void {}
    If ((event.currentTarget_as_InteractiveObject).enabled) {}
    ... Things //Your here
    }
    }

    It will run only then the code when the image is selected.

    If you want to have the image as the button, you can extend it and save a listener in the constructor for the click event. Inside the listener, if not enabled, call event.stopImmedatePropogation ().

  • Receiving duplicate E-Mails

    I continue to receive the same batch of emails - from different senders - and spent a good part of the morning removing them. My client is Outlook Express and I am running windows XP Home Edition. How to stop receiving these duplicates?

    First, make sure that the account is not listed twice in tools | Accounts. If it's OK, follow these steps.

    Tools | Accounts | Mail | Properties | Advanced. Uncheck: Leave a copy of messages on the server. Then, remove the Pop3uidl.dbx file. You will get the messages once more, but it should be.

    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.

    In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.

    With OE closed, find the Pop3uidl.dbx file and delete it.  Another will be created automatically when you open OE.

  • Receive duplicate emails.

    I use Windows Mail. Recently, I did a tour and need to access my e-mail through the server of my ISP. They have me remove my password in the Windows mail program (in the "servers" tab) to keep my mail on their server. Now that I'm home, I entered my password, but now I'm getting duplicates of every email that I receive. I talked to my ISP - they said that it is a problem of Windows Messaging. How to avoid e-mail duplicate?

    You are the OP with a different display name? What mail client do you use?

    Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the CPUs, slows down sending and receiving and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for the loss of messages. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:
    http://www.oehelp.com/OETips.aspx#3

    Why you don't need your anti-virus to scan your email
    http://thundercloud.NET/infoave/tutorials/email-scanning/index.htm

    Note that for some AV programs, it may be necessary to uninstall the program and reinstall in custom Mode and uncheck analysis when the option is the result of e-mail messages.

  • Cannot edit or duplicate events

    I have implemented some new features, but when I go on edit information (to change the time, add banners etc) it won't save my updates on SOME of them. Some I can edit without problem, but the rest will not update after I click on 'Save' - the information is just like the original.

    Also, when I try to reproduce an event that I am taken to the screen after clicking on 'Save' that says 'Unprocessed request, contact Support'. I suspect that this is a bug that I was able to exercise these functions in the past with no problems.

    Any advice greatly appreciated

    Hello

    We are aware of this problem and to research the root cause of this... With the information available to us, we assume that this only happens with events created before C9.2... New events should not have this problem. Please correct me if I'm wrong...

    We'll let you know as soon as an update is available for the same thing. Until there solution is to create a new event instead of duplicate/edit old events.

  • How certain actions between received the event and related events

    Hi all!
    Sorry my bad English :(

    I want to review the event data (to compare with the form of java method courses) after the event received and match, but before he bound.
    How could I do?

    Have you checked RCD_VALUE?

    You have Network KEY and you can extract the data from table RCD with this NCE KEY.

    ignoreEvent will not work in your case because it is not a custom connector.

  • BlackBerry smartphones, receive duplicate emails

    My boss received a copy of every email sent to her.

    The BB has a single e-mail account - company that she uses on our Exchange Server - and the BlackBerry Manager software on our Exchange Server lists only him once.

    What could cause to pick up emails in double like that? Its user profiles are not, to my knowledge, duplicated anywhere to cause this.

    -Well 2nd e-mail can come only through BIS (blackberry internet services) and if you deleted it on the "e-mail setup" icon there are no average 2nd E-mail will come on the device.

    -Log in the website of the BIS from your PC if you know the user name and pw for BIS account and delete the e-mail from there as well and on BB under Options-advanced options-service book; remove entries from service book two under the name "[email protected]".
