• Help me. Will be the Trigger below cause performance problem?

  Experts,
  
  I'm Mohanasundar, senior Software engineer, Antares limited systems. We use oracle for our product. 16 years one of our capture of audit trail table (* LOGTABLE *) do not have a primary key column. If we write at the same time more than one journal to LOGTABLE, the column was even, due to which order of this column wasn't properly.
  
  To avoid this, we have added the trigger of bellows for LOGTABLE.
  
  CREATE OR REPLACE TRIGGER TR_PK_ATTACH_TBL+.
  BEFORE INSERT ON ATTACH_TABLE FOR EACH LINE.
  DECLARE A1 NUMBER +
  START to+.
  * SELECT LOGTABLE_SEQ. NEXTVAL IN A1 FROM DUAL; *
  *: NEW.LT_INDEX: = A1; *
  END; +
  
  LT_INDEX Here are the newly added primary key column.
  LOGTABLE_SEQ is an oracle sequence.
  
  This table contains about 10 million documents.
  Initially we updated the sequence for the LT_INDEX column to existing records.
  
  Details of our server:
  
  OS: windows Server2008 R2
  Web server: Apache Tomcat 6.35
  Oracle: 11G
  
  The problem is,
  
  "* We made this change to the production for the last version (this month)." "Our teams COMPUTER, reports that after this change, the site is too slow (Server Web is in place, but the answer is too slow)."
  
  Will this trigger slow the performance of oracle db? *
  
  Please help us, our eight month project is literally dependent on this key.
  
  Thank you

  Relaxation itself I do not introduce overhead costs have a significant impact on performance, and I can see why you would use an approach to relaxation based during the redevelopment of this on an existing system.
  Could really do with some stats here, an AWR report on a busy to begin with.

  But I'll take a guess - could be contention on the right-hand side of the index, a hot block as all these inserts are consecutive values are inserted.
  A reverse key index could (maybe with the emphasis on the word!) help here.

• Having a problem with the trigger. (need help)

  Hi all
  
  I m totally new to the PL/SQL... hope someone can help me with this...
  
  I am now using the trigger to block insertion in the 'attendance99' table when records reach the maximum limit and insert the record in the table «waiting_list»

• I'm trying to get my vi to trigger, do not know where to add the trigger

  I need a vi that can trigger using an analog front (1V), then produced a square wave (all square wave will do for now) and then show the extent of the wave.  Attached is the code that I've done so far.  Not sure how to get a trigger attached, or where to put the trigger on what I've done so far.  Another question is where it is triggered since then, I have to add another generating the waveform to produce the trigger signal?

  Any help is appreciated!

  Hello

  You can place a start trigger VI DAQmx in the code above, between the Timing DAQmx and DAQmx write screws and then set the trigger to "Analog Edge" type and specify the channel to trigger of (in this case, I think that you should use the APFI line on your map).  Discover the 'voltage - output continuous' example ' If you need help implementation of this code, this example includes outputs analog with different trigger types in a similar setup to yours.

• How do I auto detects the target using the trigger VBAI mode

  Hello world

  I had a vision system of machine ready to take choose using VBAI 2013 sp1.  Also, I use a sensor switch to trigger the camera to take pictures.

  When I type the loop running, it just won't continue to take photos no matther switch sensor triggers the camera or not.  I think it's the step that I used for the recording of the image, in the stage of registration of the image, I used picture newspaper still, but I don't want to use which is only what inspection status allows no other choice.

  So, how can I let the unit wait until he got the trigger of the alarm switch signal, and then take a picture and save the image?

  the stage of inspection to acquire the image, I used the trigger mode and everything worked fine, except the time error settting upward, I used 5000ms and if I put bigger like the 50000ms, VBAI turned really slow and showed time out error.

  If anyone can help me on this matter?

  Thank you

  You can use the diagram States-transitions to go only in a State based on the result produced by some steps.

  First, remove the registration step of the image of the State to check with you get the image

  Press Ctrl + E to turn the main view on the state diagram.

  Right click and create a new State.

  Right click on the State to inspect and create a new transition to this new State.

  Double click on the transition to edit it.

  Choose to acquire the Image - waiting time and set the condition false, to spend in this state when there is no timeout.

  Move the default transition from that State to the final State.

  Click on the new State to select it, and then add the image registration step.

  Using a state diagram, you have programmed an inspection that will record the image when there is no timeout.

  The State-transition diagram is a powerful tool to add a logic, branching and looping of your inspection.

  Open the tutorial 5 - state diagram Branching.vbai and tutorial 6 - State chart Looping.vbai for examples on how to use it.

  I hope this helps.

• Writing data to the file when the trigger is activated?

  Hi all

  I'm quite new in lab mode, and I find it difficult to find a solution to this problem quite simple. I installed a gauge on a tank, and each time, he reached the limit of overflow of the VI should write all data to a file. I implemented my data tables, but I am struggling to find a way to have the VI writing the data when the specific trigger (the tank overflow) occurs. I'm sure the solution is quite simple, but was faced with this during a few days now so I decided to ask for help.

  See you soon,.

  Seems to work, but the program stops when the trigger activates and asks you a file name to write on and then reset the whole process. Is that anyway so he can write the data automatically, without any interruptions?

  Yes, simply son by the name of desired file in VI of file write. If a cable it won't entice.

• the trigger for camera AVT Pike-based software

  Hello

  I'm using labview 8.5, as well as the acquisition of vision (IMAQ-dx, latest version) software, to control a cross beam motion detector and AVT pike camera using a high speed cable IEEE 1934 (800mbps) b.

  I wish to have a trigger internal (software) control system and have no problem to get Boolean cross beam sensor signal or run indepedently of the camera (about 300 FPS).

  The problem is the trigger.  I have a problem with where to put the camera vi in the relation to the probe wiring diagram.  In the image as an attachment, I have the sensor in a loop and the camera, in a nested loop.  However, when I trigger the camera manually with a push button, the sensor stops running.  And when I try to control it with the sensor instead of the push button, I can boot, but cannot stop the camera.

  Basically, I just want to know if there is a method of internal trigger to control camera image recording.

  Thank you for your time,

  Veritas

  Ah yes! just before I read your reply I tried... and it certainly helped.

  Thank you!

• Relaxation and door, timing of the trigger.

  
  

  Hi Companyqwe,

  After reviewing your code a little more in detail, I suggest that in which you may be able to measure the time between your start trigger and your trigger to stop is to get the timestamp at the point at which your starting threshold is exceeded, and then back to the place where the stop trigger level is exceeded. These values of time stamps could then be subtracted to determine the total duration of the trigger.

  I built a very rough example to illustrate how this could be done. You can apply a principal similar to your request.

  I hope this helps.

  Best regards

• Task Scheduler ignoring "expires" field of the trigger

  I have set up a task to run a simple command (rundll32.exe with some settings) on Windows 7. The task is triggered by workstation unlock, has an expiration time/date (checked = active) and is enabled.  I set the timeout at 11:25 August 1, 2012, the time current 11:20 1 August 2012 and locked the workstation, then unlocked it. The evnt triggered very well. But when I blocked the workstation after 11:25, it triggered yet, even if the HELP says "expires: this parameter allows to set the date and time of the trigger to expire." When a trigger is expired, it cannot cause the task to run'.

  The task history indicates for each time I've unlocked the workstation: task triggered unlocking > engine message received task to start the task > task started > Action began > created the task process > completed > completed.

  It does not show errors or other messages, and the final message is stamped the same second as the first journal, so it is running and completed in less than a second.  So why is it always triggered when the present time > timeout?

  Any help appreciated, it's weird.

  I have no way of telling if this is relevant to your case, but TechNet explains that, for the parameters of expiration - time is relative the time zone set on the computer that runs the task. Check the universal check box to make the time from universal time coordinated (UTC) instead of the time zone set on the computer that runs the task.  Did you accidentally check universal, perhaps?

• How to hide the trigger on the top layer

  Hello

  can someone help me with this problem?

  Each icon is a trigger in the other layer.

  When I clicked on the icon, it will display the target (white box), but somehow the other icon is always on display.

  I tried to move the layer to the trigger, but it cannot be moved anywhere on the layer.

  I thought to create another separate page for each icon, but it will not reach the design I wanted.

  Can someone help me how to get the icon disappear please?

• Cannot change the size of the trigger

  whenever I try to change the size of the trigger, it returns to its original state as soon as I let go of the mouse. This is a problem because now all my goals are overlapping.

  I don't know if this is necessary, but it is a picture with a smooth rolling inside the trigger that is connected to a composition of light-box with a slide show placed inside that.

  any help?

  I'm assuming you are trying to set the trigger smaller, if you do this make sure that there is nothing else inside the trigger that is greater than to be the trigger. most of the time for me, I have a text box in mine

• Need help with the symbol 'start '.

  I created an animation symbol to illustrate the continuous flow of balls along a path.

  The element is called Ellipse and repeat at the end of the timeline by sym.play(1000) (0); (see first attachment)

  Ellipse is part of a named symbol S1, which is repeated 3 times with a STOP in time 0.0 and the offbeat GAME.5 second. (see second attachment)

  S1 is part of a symbol named AH. (see third attachment)

  I created a button with an action that triggers F - IN on the timeline, which produces a sequence of fadein. The action is simply: sym.play("F-IN");

  My question is: how to make the animation symbol AH 'start' of the first ball when the trigger is activated (button)? When the action is triggered the animation AH already plays.  I tried sym.getSymbol("AH").stop (setting); in creationComplete for the scene, but the result is that the animation is already playing when the trigger is activated, and all four balls are moving in unison (it looks like a ball...).

  Not sure if I'm using all the right words - a little back to the present. Please let me know what other information I provide. I use EA CC 2015 on Windows 10.

  Thank you

  

  Pittsburgh_joe,

  I think that I finally thought to it. I had to modify the symbol AH and S1 and set 'Autoplay' to 'off '. Then I had to issue a sym.getSymbol("AH").play (0); to start the animation when the F - IN action has been triggered. Once the animation is played I could just fade in and out.

  Turns out that I was also going through my stop() action that I put in 1 sec on the timeline to 0. A lot of trial an error... but it seems to work ok now.

  Here is a LINK to a video that explains what I was trying to actually do.

  Thanks again for your help!
