To synchronize using the dbms_lock

Hi all

We have a requirement that we need to make sure there is only one instance of the stored procedure call to a given input value (which is a JOB_ID), and I intend to use it as the name of the lock. I'm evaluating to see if we can achieve this by using the dbms_lock instead of going to a table with a row-level lock on it.

Could you please let me know if the amount of the fine to make use of dbms_lock to achieve? Are there limitations to use?

DBMS_LOCK is specially designed for the application of block level (aka the protection of resources or serialization).

So yes, it does what it is supposed to do - when user code use it CORRECTLY. And this is where the crisis is - like serialization (as for parallel processing using DBMS_PARALLEL_EXECUTE) requires sane and logical grounds.

  • Evanescent synchronization using the TTL trigger

    Hi all

    I work with the NI DAQ (PCIe 6363) set and uses a waveform as outputs analog to control a scanning unit.

    Now I want this output to synchronize with the rising edge of an external TTL signal (the * fire * out of a camera).

    To do this, I used [Cont Gen tension Wfm - Int Clk - analog Start] - model with minor changes (see attachment with a few comments included). In fact, it works, but only if the output signal is long finished when arrives the next TTL climbing aboard. What I want is a rising edge trigger that happens, say, 100 Hz, and a waveform near 10 ms-long that starts with this trigger. So far, I have to operate with a approx. 8 ms wavelength. It seems to me that the loop in Labview (see attachment) software takes the rest of the time. If I increase the wavelength to 9 ms or more, the loop is too slow and little miss the next rising edge trigger.

    Unfortunately, I can't use [continuous sampling] that there is too much instability in the external trigger.

    Is it possible to optimize this problem? For example, is it possible to tell la carte DAQ 'turn off this waveform whenever you receive the trigger"instead of"put on this waveform when you receive the trigger, then shut up? " Or is it possible to run two while loops in parallel that alternately hold the trigger signal and both use the same output channel? There is another, simpler solution?

    Thanks for the pointers,

    You must use the property start.retriggerable, something like this:

  • Lot of audio and video synchronization using the timecode

    I'm having an impossible time finding what I thought it was a very basic feature.

    I have two cameras and a set of audio, all synchronized SMPTE timecode container.

    How can I synchronize their all this?

    Here is the audio, here's the video. Synchronize them to me using the timecode. Pretty simple right?

    The function "merge clips" only allows me to synchronize a video clip at a time to an audio clip. At this rate, it will take me hours to select each file individually. Is he seriously not a function of batch processing?

    Not that I know of.  It is at the same time.

  • Lost my domain name and cannot use the old e-mail address to pass to the new email address,... help

    my email address was on a domain that has been taken over by another person / company.
    As a result, my email does not work and I can't receive emails about this address any longer. All emails do not reach the cross. How can I change my email address on my account in Mozilla?
    Should I create a new account to Mozilla, and if so I lose all the data on my existing account?

    Specifically, "representing Mozilla?

    As a general rule, your email address is used as your username for most, if not all of the subdomains of the Mozilla, so you'll need to create a new account for each subdomain that you are registered with who uses this old email address.

    Now, if you are referring to an account of Firefox used for the synchronization service, untie all your devices that use Sync and create a new account in Firefox. Then "link" all of your devices to this new account, Firefox, using synchronization of the configuration on each device. You should not lose your data because when you reconnect to the synchronization using the new Firefox account, your data will be synchronized your different devices on the server synchronization across again.

  • BlackBerry Smartphones changing "synchronize using" for contacts

    I used to use BES, but now I'm on BIS.

    I want to synchronize my contacts with Google Apps / Gmail, but all my existing contacts say "synchronize using the: Desktop", while the new contacts I create say "using synchronization: [email protected]". "

    How can I move my contacts from Gmail?

    Thank you

    Weird. I thought I posted a follow-up. I wanted to move the contacts you want to synchronize with my Gmail / Google Apps account here, that's how I got it working:

    Download the free "ABC Amber Blackberry Editor" (not to be confused with ABC Amber Blackberry Converter, I paid $19.95 for which it did not help) among Free Download ABC Amber BlackBerry Editor, edit contacts in IPD files.

    Create a backup of your contacts via Blackberry Desktop Manager.

    Create a new backup (via the backup and restore-> advanced) only on the "Address Book - All" database, and save this as a separate file, IPD.

    Clear (empty) both the 'address book' and the 'address book' all databases.

    ABC Amber Blackberry Converter, open the second IPD file and save it as an IPD file another (in hindsight, I wonder if this step is not necessary).

    Use the Fund Manager to restore from that IPD file. All contacts are now under the BIS address.

    The strange thing is though (nothing to do with my previous question), if I edit a Contact in Google Apps / GMAIL, address, city, State and zip all move in the field "address" in my BB contacts application (all on one line). I can change it back to normal (i.e. address, city, State and zip in their individual fields) on my BB, but the next time I have edit the contact in Google Apps, it goes back on a single line.

    (I BIS contact SYNC, don't use BES).

  • How will I know if I use the new synchronization?

    Want to know if I need to go through the new process of synchronization of devices not linking the synchronization of the former and the reset to the new synchronization.

One of my ideas was to connect to my office computer, sync all bookmarks, and then switch to the new sync - but unfortunately being unused for years, it turns out that the monitor was dead, and the graphics card seemed to be roasted (felt like it anyway).

    Any ideas?

    This may not work (Firefox sync isn't a backup system, so this will probably fail), but it's worth a try:

  • What is the difference between REFin and PPSin? Can I use the PXI-5652 to synchronize USRPs?

    Hello world!

    I'm working on a project I want to synchronize 8 USRPs (USRP 2920) as receivers. And it seems that PXI-5652 has a connector REF, so I decide to use it as the reference of the USRPs 8 clock. But I don't know how to connect the PPSin, and in fact I'm confused of the difference between the REFin and PPSin.

    Thank you!

    Jay_c salvation,

    In short,.

    REF is the terminal for the device USRP to accept a signal from external reference frequency (10 Mhz).

    PPS is the terminal for the device USRP to accept a signal from external time source base clock (1 pulse per second)

    You can see this whitepaper for a detailed description of MIMO system about 8 * 8.

    Please refer to the section "time and frequency" for information specific to your question.

    http://www.NI.com/white-paper/14311/en/

    I'm not sure whether you can use the specifically 5652 signal generator for your application.

  • Receive the error message of synchronization video on YouTube, but by using the preset first YouTube

    Hello

    I use Premiere Pro to edit video to my YouTube channel for just about a year now.  In total, I made over 200 videos and never run into this error before.  However, on my last two videos, I got an error/warning of YouTube stating "you downloaded a video may have audio/video synchronization problems.» Please to refer to this article for tips on how to fix this problem it occur. "So, I checked my local file and haven't seen any problems with syncing audio and video, and then decided to leave the full download and see if something was off about downloading YouTube.  I watched the YouTube Uploader several times on portable devices and saw that no audio/video synchronization either questions.  My process is fairly simple, I take the .mp4 files, combining with audio .wav and export using YouTube 1080 p HD preset first.


    It drives me crazy to try to understand what I'm doing wrong here.  The only thing that has changed recently is that I am now on as opposed to 8.0 9.0 (I am a client of creative cloud, I pay $19.99 for the one application).  A test, I exported in fact just a second 20 video file with any audio using YouTube 1080 p preset and received the same error message.


    Someone please help, I'm completely lost here.  I thank in advance for any help, you may be able to provide.

    Adobe has changed the audio engine, but I don't think that should affect the export format/codec. I did a quick export using the preset youtube and looked at using mediainfo, it showed everything in order. the video and audio have the same length and no delay on the audio track. So it may be a false positive, as j.simon says. You can use mediainfo to check yourself if there is something different between export of version 8 and 9. MediaInfo - download

  • How can I synchronize catalogs on 2 computers that use the same location for the image files?

    I do not understand Lightroom.

    For example, I use LR4.2 on a desktop computer and a laptop computer. Two computers (Windows 7 64-bit) go to the same image files. On my laptop in a folder, I have 42 master images and 5 virtual (virtual events) for a total of 47 images. But when I open LR4.2 on the desktop I do not see the 5 virtual (virtual events) on the 42 master images.

    Why can not I see the 5 virtual events since I can access the exact file and how I see the virtual evidence created on the laptop on the desk.

    It has no function in LR to synchronize catalogs.

    If your pictures are on an external hard drive, you can move the file catalog to this external hard drive, and then you will have a catalogue on your desk and another on the laptop. Just use the one on your external hard drive.

    If your pictures are on a network drive, you can not put the file catalog here, so the only answer I know is to manually transfer the catalog back from one computer to the other file.

    Why can I not see the 5 virtual events since I can access the correct folder

    Lightroom does not save your work to the photo files. It stores your work in the Lightroom catalog file.

  • Synchronize the analog continuous entry and continuous analog output using the unique PCI6024E data acquisition card

    Hello

    I want to generate the continuous signal and at the same time I want to read that signal that I generate using a single card DAQ. I want to generate signal and the received signal is synchronized and in phase.

    I looked at several samples on the sync, but it quiet confusing. One using the same clock of entry while the other use a trigger to start. I use the PCI-6024E DAQ card.

    Can someone help me in this regard?

    In two of these screenshots, the task to HAVE started first (that's what you want, because it is the task of the slave).

    Typically for AO, you can simply write a unique period of your waveform, and then regenerate again and again.  Your waveform would be preset before the task starts.  If you need to update the waveform on the fly according to enter programming during execution of the task, you would disable the regeneration.  In addition, if the wave form is such that it cannot be easily represented by a predefined buffer (for example, it is a strange frequency which is not a same ditch at the bottom of the sample clock), then non-regeneration is the way to go.
