Event-Based Logging?

Hi i like to check how do we keep track on the ftp side logging on events such as user login, upload files etc.
What i want is simple, a logfile on the transactions that the XML DB FTP server had processed.
event=”31098 trace name context forever, level 2”
i have set this in the init.ora and restart the database.
but the problem is i not sure where to find the logfile and whether doesn't it append or replace whenever there is a new transaction.
Can anyone shed some light on the FTP server features for XML DB?
I read through the developer's guided but it doesn't help much.
Thanks.

This would generate log events to the shared server log files in the bdump directory. Typically this is found in $ORACLE_HOME/admin/$ORACLE_SID/bdump on a unix box. The name of the file will be something like ora_SID_sNNN.trc.
THere will be one trace for each shared server.

  • Query on event based job in a client schema and not SYS schema

    Hi, I am fairly new to oracle job scheduler and wanted your inputs on how to create a event based job that sends a mail based on success of another job.
    I was able to implement this with the jobs being created under SYS schema. I did get email notifcation when errors were logged in exception table.
    However, now the requirement has changed to create the jobs under a client specific schema.
    The jobs got created successfully in CLIENT schema but the event based job is not working. It does not send the email notification.
    I feel this is to do with not correctly subscribing to the event queue {sys.scheduler$_event_queue}.
    Can CLIENT schema use the agent "AGENT" created under SYS to subscribe to the Scheduler event queue {sys.scheduler$_event_queue}? CLIENT is the schema in which the all jobs and procedures are created.
    BEGIN
    DBMS_AQADM.ENABLE_DB_ACCESS('AGENT', 'CLIENT');
    END;
    --Main Job that will load data and errors will be logged into exception table
    BEGIN    
    dbms_scheduler.create_job( job_name=> 'CLIENT.LOAD_DATA',                              
    job_type=>'PLSQL_BLOCK',                              
    job_action=>'BEGIN  CLIENT.p_loaddata;                                     
    END;',                              
    start_date=>systimestamp,                              
    repeat_interval=>'FREQ=MINUTELY;INTERVAL=1;',                              
    number_of_arguments=>0,                              
    enabled=> true);
    END;
    --set raise_events attribute = job_succeeded for main job
    BEGIN
    DBMS_SCHEDULER.set_attribute ('CLIENT.LOAD_DATA', 'raise_events', DBMS_SCHEDULER.job_succeeded);
    END;
    --Event Job that will send email based on condition. Condition is checked in procedure CLIENT.p_check_sendmail; If errors are found in the exception table, this job will raise exception and will be JOB_FAILED status. This job will send a email notification.
    BEGIN 
    DBMS_SCHEDULER.create_job (       job_name          => 'CLIENT.EMAIL_JOB',     
    job_type          => 'PLSQL_BLOCK',     
    job_action        => 'BEGIN  CLIENT.p_check_sendmail;                                   END;',     
    event_condition  => 'tab.user_data.event_type = ''JOB_SUCCEEDED'' and tab.user_data.object_name = ''LOAD_DATA''',      
    queue_spec        => 'sys.scheduler$_event_queue,AGENT',      
    enabled          => true);
    END;
    BEGIN    
    dbms_scheduler.add_job_email_notification ( job_name => 'CLIENT.EMAIL_JOB',     recipients => '[email protected]',events => 'JOB_FAILED');
    END;
    Is the way i am subscribing to the event queue correct? Could you please share an example/document of event based job in a schema other than SYS and how subscription is being done to event queue?
    Thanks

    Hi,
    It's a good decision you made because you shouldn't create objects in the SYS schema. I see you're using the add_job_email_notification procedure, so I'm assuming you're on 11g onwards.
    This procedure is meant to make the job easy for you. That is, you don't need to worry about setting up AQ, the procedure does it all for you. All you need to do is setup the mail server if not already done, and call this procedure to add the mail notification. That's it.
    You can also specify a filter to the add_job_email_notification procedure, so maybe you could specify directly your CLIENT.LOAD_DATA job to this procedure.

  • N82 - How to remove a single event from LOG

    Hi
    N82 has a strong loging system, all events will log, but it is not interesting when you dont want your wife read your mobile logs :-D
    There is an option to remove all log entries but who can I only remove one event entry from the global log report ?
    usually in all systems when u highlight an entery you can press "C" key to remove it, but there isnot such option i have just one option to remove all !!!?

    From the interface, you can't. At try with my n95 many times but no luck.

  • How to create event based process chains

    Hi All,
    I would like to know about event based process chains. In connection to this, could you please answer the following queries,
    1. How to create events
    2. How to link created event to the process chain in the same BI or BW system and as well as from  
        externel BI system.
    3. How link one process chain with other process chain (i.e, After completion of one process chain, it
        should trigger other dependent process chain)
    Thanks and Regards,
    Kotesh.

    1). Doubt regarding first question.
    For example, i would like to create time based event (it should be trigger daily at specified time),
    where we have to maintain scheduling options while creating event.
    When i checked SM62 there i found only two options a). Event name and b). Description.
    Could please send any doucument link if you have.
    Ans : You can use function modules like "BP_EVENT_RAISE" in a program and schedule the program to trigger.
    2). For externel BIW system also same procedure we need to follow or any difference.
    Ans : Externally you need to trigger the same event.
    3). i found dependent process chain also had scheduling options as direct scheduling insted of start using meta chain or API. As you said dependent process chain should be mata chain. it seems dependent process chain may be Meta chain or Direct scheduilg.
    Ans : Its your choice how you want to schedule it.You can either make that dependent chain a metachain or schedule it separately.
    I found at the end of first process chain they kept one process like Raise event and second process chain connected with the help of raise event process event name. If you have any idea about this process could explain a bit more.
    Ans : May be they are raising the event in the main chain and triggering the dependent chain using this event.
    But Metachain is preferred for such thing.Though it does similar thing.
    Hope this helps.

  • How to set a default start and/or end date for New Events based on trigger date.

    I'm using the CalendarActivityListener to get current row when clicking on an existing event. As per previous posts this listener gives you access to event detail including Start Date, End Date, etc.
    However, what I want to do is to default the start (and end) dates for New Events based on the trigger date.
    I've tried the CalendarListener and can grab the Trigger Date from it - however, I can't see a way to pass this directly to the popup/dialog I'm using to create the new event.
    At present I'm putting the TriggerDate into the ADFContext session scope e.g. ADFContext.getCurrent().getSessionScope().put("TriggerDate",calendarEvent.getTriggerDate());
    Then, I've tried multiple approaches to try and "get" the TriggerDate from session scope to drop it into my new Calendar Event basically, I'm trying to default the InputField(s) associated with the Start Date using the value from the session - I've tried
    1. setting the default value for the InputField in the jspx using a binding expression i.e. value="#{sessionScope.TriggerDate}" - this actually sets the value appropriately when the jspx is rendered but, when I go to create I get a NPE and I can't debug. I assumed that it might be a Date type issue - it would appear that CalendarListener provides a date of type java.util.Date and that the StartDate attribute of my VO/EO/table is a DATE and therefore requires oracle.jbo.domain.Date so I tried casting it - to no effect
    2. Using a Groovy expression *(StartDate==null?adf.context.sessionScope.TriggerDate:StartDate)* in my calendar's EventVO to default the Start Date to the same result
    Any thoughts or ideas?

    John,
    Thanks for that suggestion - could not get it to work. However, I did manage a different approach. I finally determined the sequence of events in terms of how the various events and listeners fire (I think).
    Basically, the CalendarActivityListener fires, followed by the listener associated with the Calendar object's Create facet, followed finally by the CalendarEventListener - the final is where the TriggerEvent is available and then finally, control is passed to the popup/dialog in the Create facet. So, my approach of trying to set/get the TriggerDate in the user's HTTP session was doomed to failure because it was being get before it had been set :(
    Anyway, I ended up adding a bit of code to the CalendarEvent listener - it grabs the current BindingContext, navigates through the DCBindingContainer to derive an Iterator for the ViewObject which drives the calendar and then grabs the currently active row. I then do a few tests to make sure we're working with a "new" row because I don't want to alter start & end dates associated with an existing calendar entry and then I define the Start and End dates to be the Trigger Date.
    Works just fine. Snippet from the listener follows
    BindingContext bindingContext = BindingContext.getCurrent();+
    *if ( bindingContext != null )    {*+
    DCBindingContainer dcBindings = (DCBindingContainer) bindingContext.getCurrentBindingsEntry();+
    DCIteratorBinding iterator = dcBindings.findIteratorBinding("EventsView1Iterator");+
    Row currentRow = iterator.getCurrentRow();+
    if ( currentRow.getAttribute("StartDate") == null)+
    currentRow.setAttribute("StartDate", calendarEvent.getTriggerDate());+
    if (currentRow.getAttribute("EndDate")==null)+
    currentRow.setAttribute("EndDate", calendarEvent.getTriggerDate());+
    *}*

  • I need help with my event-based cue points with audio

    Im having trouble with my video game project for my action script 3 class at school. Here is what i did, i made a game called Tailgate toss up. I filmed my character and rendered it in Adobe Premiere. I than brought my .mov file into After Effects and I put event-based cue points-
    my first cue point at 0:00:03:13 called "loop"
    my second cue point at 00:00:03:27 called "draw"
    my third cue point at 00:00:05:24 called "bang"
    my fourth cue point at 00:00:13:29 called "dead"
    my fifth cue point at 00:00:14:29 called "You Lose"
    my last cue point at 00:00:19:14 called "End"
    Here is my action script 3 code
    ///first frame:
    start_btn.addEventListener(MouseEvent.CLICK, startGame);
    function startGame(event:MouseEvent){
    gotoAndStop(2);
    SoundMixer.stopAll()

    var client:Object = new Object();
    client.onCuePoint = onCuePoint;
    vStream.client = client;
    var myVideo:Video = new Video(418, 480);
    myVideo.y = 0;  ///this adjusts where the video is, right now it is the size of the canvas which is 418,480
    addChild(myVideo);
    myVideo.attachNetStream(vStream);
    vStream.play("michelle.flv");
    var throw_bottle:Sound
    throw_bottle = new Sound(new URLRequest("audio/throw_bottle.mp3")); //change to button noise, will add sound into ae file
    target_mc.addEventListener(MouseEvent.CLICK, shoot);
    target_mc.buttonMode = true;
    target_mc.visible = false;
    draw_mc.visible = false;
    function onCuePoint(cuePoint:Object):void {
       if(cuePoint.name == "loop"){
    loopTime = cuePoint.time;
        if(cuePoint.name == "draw"){
    var randomLoop:Number = Math.random()*10;
    if(randomLoop > 2){
    vStream.seek(loopTime);
    }else{
    setChildIndex(target_mc, numChildren - 1);  
    setChildIndex(draw_mc, numChildren - 1);    
    target_mc.visible = true;
    draw_mc.visible = true;
    if(cuePoint.time == "5:24"){
    draw_mc.visible = false;
    target_mc.visible = false;
    if(!hitHim){
    vStream.seek(15);    
    if(cuePoint.name == "dead"){
    vStream.close();
    myVideo.clear();
    gotoAndStop(3);
    if(cuePoint.name == "end"){
    gotoAndStop(3);
    function shoot(event:MouseEvent){
    throw_bottle.play();

    playAgain_btn.addEventListener(MouseEvent.CLICK, playAgain);
    function playAgain(event:MouseEvent){
    gotoAndStop(2);
    SoundMixer.stopAll()
    stop();
    When I have no audio it works perfectly, no problems. When I bring audio in i re-render it as a .mov file and bring it back into After Effects and add the cue points to it. Than i re-render it out again as a flv file. When i bring it into my flash project it will work when the looping variable does just one loop and my target will appear so you can click on it or not. But when the looping variable makes it loop 2 to 10 times it skips over the catching (the part of the clip if you clip the button) and goes directly to the dropping of the can, not giving you the option of clicking the button. So basically it skips the "draw" or second cue point of my game and goes to "You Lose" cue point.
    Any suggestions?

  • ATV and Photo App: Event based sorting disappeared

    With the new update to the new Photo app, I can no longer view my photos from my TV (via my Apple TV) sorted by "events."  Everything is sorted only by the actual folders the pictures are in, and since most of my photos are in the iPhotos Library "file" I can't sort these in any useful way.
    Please fix this so that I can view the photos using the events based sorting method, which is how I have been organizing my photos for the last several years in iPhoto.  Thank you.

    Thanks for the reply.  I went to iTunes --> Files --> Home Sharing --> Choose Photos to Share...and was able to click on the share "Photos" option from the pull down menu.  This wasn't there yesterday so looks like there was an update in the meantime. 
    The problem is that the photos are shown in chronological order, so it's a pain to scroll all the way down to get to the more recent photos.  Hopefully Apple will fix this soon, like the way they had it in iPhotos.

  • Windows Server 2012r2 Failover Cluster Event Trace Log files

    Hi
    The only documentation I can find regarding event trace log files (Diagnostic.etl.*) for Failover Clustering relate to Server 2008/2008r2, which state that the etl files should be in C:\Windows\System32\winevt\Logs.
    I have been exploring a clustering lab for Server 2012r2 and cannot find these files in that folder.
    Strangely the PS cmdlet Get-ClusterLog still works!
    Where are the etl files?
    TIA

    Hi,
    Please check if the log is available in C:\ProgramData\Microsoft\Windows\WER\ReportQueue\.
    If not, you can use Get-ClusterLog with the Destination parameter to get the log file.
    Destination
    Specifies the location to copy the cluster log(s) to. To copy to the current folder use "-Destination ." for this parameter.

  • Error handler for event based messaging framework

    I've been very interested in using the event based messaging framework (described here http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/td-p...) for my next large application.
    My main concern is the fact that it seems like typos would be very difficult to debug since you need to ignore unknown commands to make this system work.
    To solve this problem I've been considering the idea of having a single message error handler VI which will store all valid commands and check all sent commands to see if they are valid.  Each VI would send out a register message on startup with their name and all messages they can send and receive.  The message error handler would store these and then check all future messages to be sure it is a valid message, throwing an error if it is not.
    My basic problem is this: for this to work the message error handler VI would have to be started before any messages are sent so that it can capture all the register events.  If this is a VI that will be continuously running the entire application how can I ensure it starts first since I cannot wait for it to complete? (I.e. the usual method of running an error out wire or using a sequence structure will not work since everything will then wait for it to complete which will not happen until the program is ready to shut down)
    I'm assuming the answer might be to use an asynchronous call but I'm not very familiar with this method.  
    Any help is appreciated.  Thanks. 

    Could you just use the error handler as a subVI inside a case structure that is only called when you have new message to be checked? I'm not sure I understood the exact functionality you are looking for, so sorry if this does not apply.

  • Generate an Event based on Counter Trigger

    Hello,
    I have the following part that is already working: a counter (used for period measurement) which is triggered by a digital input. After that I'm reading the data and I'm puting them in a Queue. Here I get an error. The Enqueue Element Vi is providing an error. (Error 1, something with a @  character that is illegal). I've notice that if I disable the trigger for the counter I don't get the error. I'm thinking that this is cause by the delay between the moment in which the Enqueue Block tries to enqueue and the moment in which the counter provides something to its ouptut.
    What I want to do is to Generate an Event based on the Counter Trigger Signal and to put all the reading and Enqueue part in an Event Structure. I've tried to do that using an Export Signal - Property Node, but I didn't manage to make it work.
    If you have any solution for this (with or without events -  I just want to get rid of that error) please let me know.
    PS: I have Labview 8.5.1 and the USB-6210.

    Thanks for your replay.
    I've attached two vi files. In one you can find how I've tried to generate an event based on the counter trigger (test.vi).
    The second one (test1.vi) is the vi where I get the queue error. I've deleted from the second vi the part where the data are dequeue and handled.
    Thanks

  • How to run a particular case continuously in event based state machine architecture.

    I am making a program using event based state machine architecture, it is running as expected whenever i am generating an event, case structure corresponding to that event executes.
    we are taking some measurements from oscilloscope e.g. i am having one boolean button for rise time whenever i am pressing that that button it displays the value of rise time, it displays only once( since i have generated an event on that boolean button so it executes only once and displays value for one time and then comeback to timeout state) but in our program what we want, we want it to update value continously once that button is pressed.
    Now for a time being i have placed while loop on the case corresponding to rise time but this is not the right approach.
    since i am using state machine architecture( event based ), i am not getting how to run particular case continuously ,or if there is any other better architecture that i can use to implement the same application.
    Attached below is the program.

    Say, in the attached program, when the user selects Autoset, it inserts corresponding state (Autoset) and now if you want this state to run again and again, probbbly you can again insert Autoset state while executing Autoset state... ohhh its confusing... check the picture below (A picture is worth a thousand words):
    1. Based on user selection, insert Autoset state.
    2. Re-insert Autoset state again and again while executing Autoset state.
    3. Now to come out of this loop, based on appropriate event generation, insert any other state AT FRONT (equivalent to Enqueue Element At Opposite End).
    I am not allergic to Kudos, in fact I love Kudos.
