JDBC connection to two different machines from the same program

I want to use JDBC to connect to two different databases that are on two different MySQL installations on two different machines.
One of the installations is MySQL 4.1.12 and the other is 4.1.14-nt
For some reason, all my statements seem to be going only to one machine, even though I am very clearly set it up to go to two different machines.
Does anyone know whether connecting to two different installations from one program presents any unusual problems?
Thanks.

Unless there is some horrible defect in the MySQL JDBC driver (which I doubt!), there should be no problem and like the other poster says, please post snippits of your code so we can see what your doing...

  • Connecting to two database instances from the same TopLink

    Hi,
    We are trying to create a process using BPEL where data from one database instance needs to be passed to the other. The process is compiling properly and we could deploy it in BPEL Process Manager. But when we try to run the process, the data is not getting inserted into the second instance. There is no error /exception being thrown at most of the time, but at times we are getting a 'Unique constraint error' eventhough there is no duplication of data.
    Can we connect to two different instances using the same toplink. How can we achieve this.
    Thanks in advance

  • Why do I get two different results from the same coefficients?

    I am getting two different results from the Polynomial Evaluation function.
    For the first one, I am getting the coefficients from a Polynomial Fit function.  I feed the coefficients from the Fit function into the Poly Eval function and get the correct result of 12.8582 when I evaluate 49940.
    For the second one, I create constant array of the SAME values that were returned from the Polynomial Fit function (i typed them in).  However, I am getting an incorrect result of -120.7913 when I feed the constant array into the Poly Eval function when I evauate 49940.
    How can this happen when I am using the same array values?
    Attached is an image of what I am explaining.
    Solved!

    Hi Altran,
    are you sure about using the "same" coefficients?
    Did you compare them? Did you (atleast) set the display properties to 17 significant digits?
    Please attach a VI instead of a picture...

  • Can I run two different ipods from the same laptop?

    Hi, I am very new to all this. Is it possible to have two different ipods running from itunes on the same computer. If it is how do I separate them so when I connect and ipod it doesn't sync both lots of music.
    Please Help me
    Thanks
    Hoolie

    I'm currently syncing three iPods to the same library. iTunes will recognize each iPod as a unique device. My preferred method of managing my iPods is "Sync Selected Playlists". This allows me the convinience of syncing (and all my ratings, playcounts and last played sync) while still being able to control what goes on each iPod. You can set your preferences for each iPod. You could managage one manually and sync the other. Whatever works best for you.

  • Two Time Machines from the same computer on one external drive?

    Hello all. I tried searching for a similar situation but didn't see one.
    I have a MBP running Leopard 10.5.8. Its Time Machine is located on an external mirrored raid LaCie drive.
    I have installed Snow Leopard on a separate external LaCie d2 drive on its own partition. On a second partition of that drive is a clone of the MBP HD (with Leopard 10.5.8).
    Can the external mirrored raid LaCie drive I use for Time Machine contain both of the Time Machine backups that are created by the same MBP - one when Leopoard is running, and another when Snow Leopard is running?
    Thanks. I hope I've posed the question clearly enough to trigger thoughts. It's a brain twister for me ...

    Can the external mirrored raid LaCie drive I use for Time Machine contain both of the Time Machine backups that are created by the same MBP - one when Leopoard is running, and another when Snow Leopard is running?
    Yes, but it's not the best solution. A better solution is a separate drive or a separate volume on the same drive in order to keep the backups separate. In this way if anything happens to the Leopard backup volume it won't affect the SL backup volume.
    If you do as you propose each system's backup will be separate but stored in the same Backups.backupd folder as long as you use a different Computer Name in each system. Your backup drive will need to be large enough to maintain full backups of each.

  • How can I interact between two different frames in the same indesign template as well as from one template to another.

    I am looking for the best way (or any way) to interact between two different frames in the same indesign template as well as from one template to another. It's for a DPS app which needs to carry some button initiated data from one page to another and then present it in a table.

    There is no simple way to do it, as itunes wont let you use it on another computer without wiping the contents first.
    However if you really want to transfer songs to another computer then you could try this;
    * make sure that your ipod is accessible as a disk drive (ipod options)
    * when you plug your ipod into the computer you want to transfer to make sure you select "no" or "cancel" when it asks to wipe the contents. Leave the ipod connected and quit from itunes.
    * go to "my computer" and access the ipod directly. You probably have to select "view hidden files" from windows. You will see a lot of folders with odd names like ZX838aff with similar named files inside.
    * copy these files to a folder on your computers hardrive. Now remove the ipod and start itunes.
    * import the files from the folder you made in the last step.
    * Now your music is on itunes, but with unrecogisable names.
    This is the only way I have found to do it, but there may be another way, say with an application to do the hard work for you.

  • I am trying to store music for two different iPods on the same computer, against two different Apple IDs. When I try and download content from the Cloud I get an error message?

    I am trying to store music for two different iPods on the same Windows 8 computer, and when I try and download content from the Cloud I get an error message. Is it possible to have two different Apple IDs on the same computer?

    Unfortunately you've discovered too late how important it is to maintain an up-to-date backup of your iTunes library (and all other data of value).  You could, before wiping the drive, have considered making use of a commercial data recovery service that could (albeit at considerable cost) have extracted your library from the hard disk, even if virus infected.
    In the absence of that option, you will need to restore the content of your library from its original sources:
    Depending on your location, you may be able to re-download any iTunes Store purchases that are still available on the Store
    Likewise, most digital purchases from Amazon (including auto-rip copies of purchased CDs) should be available from the Amazon Cloud and via the Amazon Music application - the same may be true of other commercial sources for digital downloads
    Content imported from your CDs will have to imported again
    The specific situation that you describe regarding the music imported from your friend's external HDD suggests that either the source is badly organized and/or originates from a source other than iTunes (other media players may use alternative tags for information like artist, title, album, etc. that are not wholly consistent with how iTunes handle these).  Without details of the issues you're seeing it is difficult to suggest a remedy other than going through the media album-by-album, track-by-track, and correcting the inconsistencies.
    In the absence of a backup or access to the original library data there is no option other than painstakingly recreating your library as described above.  As you do so, you'll now realize how important creating and maintaining backups are - in my case I have at all times three separate duplicates of my library, in two different locations, where none is ever more than a week old compared to the content of my master library.

  • I would like to import two different cf cards from two different cameras into the same project/folder and have them be in order of the times they were taken, is there a trick?

    I would like to import two different cf cards from two different cameras into the same project/folder and have them be in the order of the times they were taken, any ideas on how to do this?

    Just import them normally and sort the project by date. They will fall into place. If you tried this and it isn;t happening then make sure the data and times on the two cameras are identical and make sure you are sorting by date and time and nothing else.

  • Collecting data from advantech-usb4704 with two different apps at the same time

    I wonder if I can access to Advantech-4704 with two different applications at the same time?
    I use this block in my vis.
    I have enough ports, but inputs are needed in completely different applications. Do I have to close one of them or can they run simultaneously?
    Thankyou!

    Dear gtu,
    as nathand said, usually it is not supported to access the same physical resource simultaneously from multiple programs. In case of DAQmx for instance, you will get an error message which says that the resource is already reserved. I suppose the same would happen with your driver, however it might be worth a try.
    One workaround could be however if you revise your applications and merge the codes if it is possible so that no concurent resource allocation takes place.

  • How do I sync two ipods with two different IDs on the same computer?

    How do I sync two ipods with two different IDs on the same computer?

    Simply connect them.  One computer with one iTunes can manage multiple devices.  They're tracked by S/N but you might wish to assign them unique names so that you can track them yourself.
    The only minor issue is app updating and purchases while on the computer.  It's necessary to log out and back in to the "correct" ID.  Much easier to do these things from the iPods.

  • Control two different parameters at the same time

    Two motors were connected each other rigidly. One motor controlled torque and the other motor controlled speed. I generated some torque and speed data which represented one cycle of motion from a motor simulation. I like to send these two different data sets (torque and speed) to two different motors at the same time. Torque data sends to one motor and speed data sends to the other motor to see the response of the load profile. In order to do this, I thought about using multithread, but I am not sure it will work for this application. Usually multithreading delay the CPU time so the overall control process might be delayed, right? If you have better idea, please let me know.

    If you are using one motion controller to control both motors, you will probably run into problems if you try to use multithreading on the PC. However, you can execute up to 10 programs (threads) at a time, in addition to host communication, using on-board programming. For more information on on-board programming please refer to the following tutorial: Developer Zone Tutorial: On-board Programming in FlexMotion

  • Why am I getting two different conversations when the same person txts me and sends me an I message? I thought they should be in the same conversation?

    Why am I getting two different conversations when the same person txts me and sends me an I message? I thought they should be in the same conversation?

    I'm experiencing something similar. My conversations are kept together but if the screen is opened to a conversation and I receive a text from that person it doesn't show up on the screen. The message alert in the upper corner indicates a new text but I have to back out of the screen and go back in to read it.

  • How can I make different catalogs from the same image

    How can I make different catalogs from the same image where that image has been changed in some way between the catalogs. For instance if I wanted to have a catalogs for cropped images and have 3 catalogs one for 4x6 , 5x7 and 8x10 cropping. When I tried this , if I changed a file in one catalog that same image in the other would change also.

    Do not confuse the creation of the crops and the display in collections per crop ratio.
    Of course one virtual copy (VC) per crop ratio is needed. If the same image should be cropped in all 3 mentioned ratios there would be 3 VCs.
    The OP asked how to have/see a set of same-crop-ratios.
    After having created the virtual copies for whatever crop ratio he wants, the way to display this result in the fashion asked for is via smart collections, provided they can be found. Without a plugin the naming of the VC with the crop ratio applied is a straight way to achieve that.
    IF the wish is to get new crops automatically added. (See my answers 2+3)
    IF the wish is to creat static collections per crop ratio for a certain set of images, I'd go as follows:
    1. Select all images you want to have cropped in that way,.
    2. With this selection click on the + to add another collection and fill the dialog box like this:
    Then navigate into this newly created selection and perform the 4x6 crop - according to taste individually or by synchronizing the first crop.
