How to have real time data in a lookup or how to update a lookup once it has been created?

Hi,
I have created a lookup from an existing table and am using it to match incoming data. I would like to refresh the lookup once  a day. Is this possible. If yes how do I go about it?
Regards

If you are looking up onto staged data, just snapshot the data once a day.
Or you could just do an External Lookup, where there is no need to refresh the data as you can just look it up dynamically.
You will not get any 'fuzziness' with this approach.

  • How to Integrate real time data between 2 database servers

    How to Integrate real time data between 2 database servers
    May 31, 2006 2:45 AM
    I have a scenario where the data base (DB2 400) is maintained by AS 400 application and my new website application based on j2ee platform access the same database also but the performance is very low. So we have thought of introducing new oracle data base which will be accessed by j2ee application and all the data from db 400 database will be replicate to oracle data base. In that scenario the only problem is of real time data exchange between 2 databases. How do we achieve that considering both the application As400 and j2ee website application are running in parallel and accessing the same information lying on DB2 400 database. We have to look at transaction management also.
    Thanks

    You certainly wouldn't use XML for this.
    The process you're looking for is called "replication". Ask your database experts about it.
    I predict that after you spend all the money to install Oracle and hire consultants to make it replicate the DB2/400 database, your performance problem will be worse.

    Yeajh I now that its not a XML solution.
    Replication is one of the option but AS400 application which uses DB2/400 DB is highly loaded and proposed website also uses the same database for retrieval and updation purpose.All the inventory is maintained in the DB2/400 database so I have thought of introducing new oracle database which will be accessed by new website and it will have all the relevant tables structure along with data from DB2/400 application. Now whenever there is a order placement from new website then first it should update the oracle database and then this data shuold also migrate to db2/400 application at real time so that the main inventory which is lying on db2/400 should be updated on real time basis because order placement is aslo possible from As400 application. So the user from As400 application should not get the wrong data.
    Is it possible to use MQ products??

    Hi,
    the answer to your question is not easy. Synchronization or integration or replication data between 2 (or more) database servers is very complicated task, even though it doesn't look like.
    Firstly I would recommend to create good analysis regarding data flow.
    Important things are:
    1) what is primary side for data creation. In other words on which side - DB2 or Oracle - are primary data (they are created here) and on which side are secondary data (just copies)
    2) on which side are data changed - only in DB2 side or only on Oracle side or on both sides
    3) Are there data which are changed on both side concurrently? If so how should be conflicts solved?
    4) What does it mean "real time"? Is it up to 1 ms or 1s or 1 min or 1 hour?
    5) What should be done when replication will not work? I mean replication crash etc.
    BTW. The word "change" above means INSERT, UPDATE, DELETE commands.
    Analysis should be done for every column in every table. When analysis is ready you can select the best system for your solution (Oracle replication, Sybase replication server, MQ, EJB or your proprietary solution). Without analysis it will be IMHO gunshot into the dark.

  • How to get real time date from Sunny Boy Inverters through SMA Webbox?

    Hello,
    I was looking on how to communicate with three Sunny Boy Inverters that are linked to a SMA webbox. Currently we get a daily summary of the solar production, but we would like to have real time data uploaded into LabVIEW. The people of SMA said that I needed to use "RS485 protocols" with a software they have called YASDI (http://www.sma.de/en/products/software/yasdi.html); however, I keep finding other information that says that I can communicate with my inverters using the SMA OPC server (http://www.sma-america.com/en_US/products/software/sma-opc-server.html). I also found this forum, http://forums.ni.com/t5/LabVIEW/Sunny-Island/m-p/809129/highlight/true#M368718, where I understood that I don't need to use the OPC server, but instead I can use UDP communication to get the data. I found another forum that talks about using the YASDI :http://forums.ni.com/t5/LabVIEW/help-with-Sunny-Boy-inverter/m-p/293273/highlight/true#M153892. 
    I've tried to communicate with the people of the forums and I haven't gotten any responses; therefore, I wanted to see if I can get cleared up on this issue. Do I need to use OPC server to communicate with my inverters through the webbox or can I just use UDP in LabVIEW?
    Any help would be greatly appreciated,
    Thanks
    Jose

    Hello,
    I got a response from Vincezo: http://forums.ni.com/t5/LabVIEW/Sunny-Island/m-p/1794786. I'm currently working with the VI to communicate with the webbox through UDP. Since the PRC protocols to communicate with the webbox are in JavaScript Object Notation (JSON), I'm not sure if the data-in string has to be in JSON format. However, the only error I'm getting is 56 in the UDP read function. I've tried increasing the size of the bytes and timeout, but I keep getting this error. If anyone can help me with this part I would very grateful. 
    Thanks,

  • Posts going missing - How to update an image once it has been displayed

    Something is very wrong with my posts here. I made this post earlier today, and added it to my watch list. The last time I checked it, there were no replies. Now the title in my watch list has been changed to null and the post is not showing up in the forum. Grrrr.
    Anyway, onto the main event.
    I've got some code that, among other things, displays an image in a Frame. I'm doing this by subclassing JLabel and overriding the paintComponent method.
    My question though, is how can I load a different image in place of that one ? I'm trying to run a slideshow, and whenever I load another image, I can see the new object is being created (I have a println in there), but the image in the frame is not updated with the new one.
    Here is my overridden paintComponent method:
    protected void paintComponent(Graphics g) {
              super.paintComponent(g);
              g.clearRect(0, 0, w, h);
              g.setColor(Color.BLACK);
         Graphics2D g2d = (Graphics2D)g.create();
         g2d.drawRenderedImage(image,null);
              g2d.dispose(); //clean up
    Can anyone advise how I would get the picture in the frame to update ?

    If you are looking up onto staged data, just snapshot the data once a day.
    Or you could just do an External Lookup, where there is no need to refresh the data as you can just look it up dynamically.

  • How do you put all your photos and videos and apps back on your iphone, once it has been restored and updated

    Dear Apple,
    I just updated my iphone from my laptop using itunes and all my apps, music, photos etc.. were on my mobile. But when the update was finished, my phone did not have all the apps it had on before it had completely restarted and I tried to restore my iphone using my laptop but nothing had changed and all my things that were on my iphone were gone and I have tried to look on websites to get back my photos and everything but there was no answer to my question.
    Please help..thankyou
    Hannah

    First, you don't have to use such a large font setting, most of us can read just fine. Did you backup your phone before doing the update? Did you reload that update after you restored your phone?  All apps can be reloaded from the App Store if needed. Have you always used this computer for all of your updates and backups? Your music can be synced from your iTunes library again also. If you did not backup your pictures or videos to your computer, you may have lost them.

  • Error: A previous document of this type has been created with later date

    hi
    when i am adding invoice with a particular date.
    and if i am adding  another invoice for same customer with date previous to the first one i am getting this error
    pls tell the error were i have made and how to slove the error

    Om,
    Pleae check the following ...
    Marketing document with earlier posting date not added
    Symptom
    Error message: 'A previous document of this type has been created with a later date.' and the document is not added.
    Other terms
    AR, AP, invoice, credit memo, reserve invoice, wizard, document, generation, past, previous, posting date, settings, initialisation, SAP Business One
    Reason and Prerequisites
    Business requirement that marketing documents with an earlier date than the current system date are entered.
    Solution
    Under Administration -> System Initialisation -> Document Settings -> Tab 'General' is a tickbox 'Block Documents with Earlier Date'.
    If this box is ticked, the error message 'A previous document of this type has been created with a later date.' is received and the document cannot be added. This affects the following documents:
    AR and AP Invoice
    AR and AP Credit Memo
    AR and AP Reserve Invoice
    If the box is unticked, the system displays the message: 'A previous document of this type has been created with a later date. CONTINUE or CANCEL.' If 'Continue' is chosen, the document can be added.
    This setting will also affect documents to be processed by the 'Automatic Summary Wizard'.

  • How to count occurences of a certain string in incoming real-time data? Also displaying RTC data. Current VI included

    I use LabView student Express 7 on a Windows XP system.
    Time-frame: we are doing final integrations for our balloon experiment today. We just got told that the press wants to view real-time data, which we haven't programmed for. I need help to get a working VI at the latest by 25.02.2004 before 0800(morning) (GMT+1).
    Note on license
    It is a student balloon flight, and the data will not be used in scientific work, so the I am not breaking any license agreements (I hope).
    Problem synopsis:
    The balloon continually transmits data at 9600baud. The data is a semi-repeating header followed by a constant lenght data-package arranged like this:
    BEXUS[h][m][s]BEXUS[h][m][s]
    [Raw binary data, 7channels*8sub-channels*8bits]
    What the groundstation is doing right now:
    Take all incomming data and save (append) the data to a file without any data-handling. (We figured we would go post-processing).
    What I need to change in less than 24 hours:
    - Add a "package" counter
    - Add a display of the clock data (RTC)
    How I planned to implement the changes:
    -RTC display:
    The RTC data is in BCD format, since that means that if you look at the data as hex numbers, you get the hours and minutes and seconds out in "clear text". That is 12 hours is 0x12hex. I figured that I can do a match pattern BEXUS and pass the "after substring" to another match pattern BEXUS from which I feed the "before substring" to a type-cast VI (casting string to u8) and displaying that, which should give me a display of "123000" for the time 12:30:00... I couldn't get it to work at all when I tried out the supplied "beta" vi.
    - Package counter:
    Counting how many BEXUS that gets detected and dividing by 2. I don't know how to do this. I've looked on the forum (a good thread on the problem: "how do I count the number of *'s in a string") but these use either loops or arrays... and I'm not sure how this works when I'm getting the data in at realtime. I cant make an array and then count it, since then the array would grow fast and possibly interfere with saving of the data??? Saving the data is critical.. without that file we cant do post-processing.
    Since my time is so limited (I'm not even supposed to do the groundstation software but they called on me in the last minute because no-one else had time/wanted too/could do it) I hope that you could make an exception and provide me with working VI's (based on the one I have attached) so that I can show something to the press! (Free comercial for NI!! Since the student version shows the National Instruments water-mark on all VI's!!! Possible TV time!!)
    Thanks!
    PS: even if you are to late (after 25) post anyway!
    Why:
    -I can learn from it
    -the launch might be delayed due to weather conditions
    -others might find it amusing!
    Thanks again!

    BexusII_groundstation.vi ‏46 KB

    I have a valid example data file attached to this thread.
    If you open BEXTEST.bin in a hex-editor of your choice, you'll see the BEXUS as 42 45 58 55 53 and then the time as 00 28 09 etc.
    I couldn't get Joe Guo's VI to work. It doesn't count packages correctly, and the time is not displayed correctly either.
    The file was saved using a straight save to file VI.
    The data is from actual launching area tests performed a few mintues ago. The time displayed is "On time" e.g. how long the gondola has been powered up.
    I have a spare T-junction, so I can hook into the balloon real-time data as we fly, in case anyone care to see if they can figure out why the latest version of Joe Guo's program is not displaying correctly.
    I will monitor this
    thread during and after flight to see if anyone can make it in time!
    Thanks for the great effort!!

  • How to get the real-time data from a CCD camera in labview?

    I am going to setup a monitor system and need to acquire the intensity of each pixel at each second from a CCD camera. Also, I need to to some simple calculations with these real-time data at every moment to get my finanl output in this monitor system.
    How may I do this using Labview?
    Thank you very much.
    Kai

    We don't have special powers, so we can't guess if you have Imaq Vision or not, if your camera comes with a LabVIEW driver, if it has an USB interface, or firewire, or a dedicated NI card, if you just want to detect a move, or a change in intensity, etc...
    So, try to be more specific with your question, that will helps a lot

  • Error "cannot load request real time data targets" for new cube in BI 7.

    Hi All,
    WE have recently upgarded our SCM system from 4.1 to SCM 7.0 which incorporated BI 7.0.
    I am using BI 7.0 for first time and ahve the following issue:
    I ceated a new infocube and data source of flat file and succesfully created transformation, and Data Transfer Process. Everything looked fine. I added flat file and checked preview and could see data. Now when I start job to load data in infocube the follwing error is shown "cannot load request real time data targets". 
    I checked cube type in setting in infcune is shows as Standard.  When I doube clicked on error the following message showed up
    You are trying to load data into a real-time InfoCube using a DTP.
    This is only possible if the correct load settings have been defined for the InfoCube.
    Procedure
    In the object tree of the Data Warehousing Workbench, call Load Behavior of Real-Time InfoCube from the context menu of the InfoCube. Switch load behavior to Transactional InfoCube can be loaded; planning not allowed.
    I did not understand what it is meant and how to set changes. Can someone advice and follow me through.
    Thanks
    KV

    Hi Kverma,
    Real-time InfoCubes can be filled with data using two different methods: using the transaction for entering planning data, and using BI staging, whereby planning data cannot be loaded simultaneously. With Real time cube you can select the method you want to use for update as
    Real Time data Target can be loaded With Data; Planning not allowed &
    Real Time data Target can be Planned; Data loading not allowed
    You can change this behaviour by right clicking on cube and selecting Change real time load behaviour and select first option. You will be able to load the data then

  • Need Suggestion On Real Time Data Accees

    Hi,
    Our application (let say A) runs on * 8.1.7.4.0*
    Another Application (let say B) runs on *10.2.0.4.0*
    Both the application A and B exchange data through DB links.
    Both the application A and B perform select and DML on other tables.
    Application A has views (approx. 10 views) on application B 's table through DB links.
    Application B also has views (approx. 50 views) on application A 's table through DB links.
    Application A has store procedure (approx 10 SPs) through which it does insert/update on two of application B 's table approx 15K call of that procedure per day.
    Application B also calls some of the application A 's procedure to insert/update data in application A 's table.
    Currently both the application's data center are at the same place. But, there is a proposal/need to move application B's data center far away from the current location. Because of these we are in a assumption that DB Link over WAN will create performance issue and searching of probable replacement.
    After of couple of discussion we have identified approx five application A 's tables which are frequently accessed by application B and expect real time data.
    Similarly, Application A expect real time data from two application B 's table.
    'Golden Gate' mechanism came in our discussion, butt it's expensive,
    Can we replace this store procedure code/dml with web service call or so ??
    Can anyone suggest ... what kind of approach we should take here ?

    Views which are residing in application A 's side use many internal tables and one or two application B s table.
    I don't have idea on 'multi-master replication ' ... is it two way replication ..? ... you aware of any documentation I can refer ..? How costly it is (if you can give an idea) ?
    Also, among many tables we need near real time (2 mins interval) replication on 5 tables.
    MVs again have dependencies on DB link, which exactly what are trying to replace (assuming performance issue)
    With fast refresh (let say 2 minutes interval) method on MVs do you think it could cause performance issue specially when data center are at different location ?
