Where are the data files?

Hi,
I'm completely new to Berkeley db and i have some basic questions regarding architecture which i couldnt find in docs. Where does BDB store its data? Is there a default file location? Also, is there a way i can specify maximum file size? I'm developing an application which will store many giga bytes of data and I dont want the data files to grow above the OS limit. I'm using windows as the OS.
regards,

Hello,
This question is probably deserving of its own thread, but I'll answer briefly here. As you've noted, BDB XML itself it designed and tuned to storage and query of XML. Because BDB XML is built on Berkeley DB, you can use DB proper transactionally along with BDB XML. In an application such as yours, you could store XML in BDB XML, and create (application-provided) references between those documents and other data stored in Berkeley DB. In addition, you might want to store some data in regular files (streaming video, large binary data, etc).
You can store binary data in BDB XML as either document metadata or encoded into ascii, but for the scale you want I would not recommend that approach.
Regards,
George

  • Where are the data files kept for 6.2.2?

    I have a client who's PC crashed.  She'd been doing full backups to Carbonite.  I've re-installed windows and the palm desktop v6.2.2 (I *think* that's what was running before).  Now I want to restore her address book.
    After doing a full recovery from Carbonite, I've got files all over the place, and copies of copies of copies.  Ugh.
    So...where should I look to restore her most recent address book?  I've searched the entire pc for *.aba, and found about 4 copies of the same file, with a date of 3-9-09.  That's *not* the last time she updated that address book.
    If I know where the files are stored, I can hopefully find them in the carbonite backup, put them in the correct spot on the PC, and be done.
    Help?
    Thanks!

    Post relates to: Palm m105

    If you are trying to access the data in a .dat file, you will want to use Palm Desktop 4.1.4 or Palm Desktop 4.2.  If you have the CD that came with the Palm, you should try installing that version.
    Once installed, you will need to create a new dumby HotSync profile; call it Test or whatever you'd like.  Then find the associated data folder on the PC.  It could be in the c:\program files\palm folder our the user's My Documents folder depending on how old the software is.
    Then, copy (don't move!) the .dat file(s) you have recovered into the correct PIM folder.  So, the address.dat file should be copied into the Address Book or Calendar folder, replacing the emply data file there.
    If Palm Desktop is still running, quit and restart it and see if the data is there.  If it isn't, the data file is either in the wrong spot or is corrupted.
    Hope that helps,

  • Where are the data files stored?

    I regularly back up using Time Machine, but when I reformatted my hard drive and then restored it, I could not find the data files for iWeb websites I have created.  Looking for help, I saw a reference to a subdirectory named "Domain", I found that but could not see any files for the four different websites I have created.  Are these data files kept hidden?  I am not very familiar with MAC file systems, so please respond in a MAC for Dummies language.  Thanks.

    In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.  Then it will be easy to fine the domain file in your Users/Home/Library/Application Support/iWeb folder.
    To open your domain file in Lion or Mountain Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
    do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"delay 1
    tell application "iWeb" to activate
    You can download an already compiled version with this link: iWeb Switch Domain.
    Just launch the application, find and select the domain file in your Home/Library/Application Support/iWeb folder that you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
    WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder.  So rename your domain files once they've been created to something other than the default name.

  • Where are the audio files located?

    You know how when your video source is missing, it shows that ! with a yellow triangle around it? Then, when you hover over the !, it shows you where iMovie expected to find the video, and then you can just move the video there and it's fixed. But for audio, it doesn't show you where it is supposed to be located when you hover over the ! in the audio file (music green bar).
    So, where are the music files supposed to be located so that it can find them?
    Thanks!

    To the best of my knowledge, iMovie simply links to the music file from wherever it is located in your system. That could be the iTunes Library, your Desktop, an external drive, or other places. So if you move the music to a different location, I assume that iMovie will lose track of it. iMovie doesn't actually import the music to the project - it's just referencing it (as far as I'm aware).
    If you know the name of the track (or tracks, or artists), try doing a search both within iTunes and on your hard drive using Spotlight. If found, the best solution is probably to drag it again into your project, then do the necessary edits if applicable.
    Note that, in iMovie the music tracks are identified by song name - it's shown at the beginning of the green audio bar. So the songs shouldn't be too difficult to track down. It's just a pain having to re-instate them.

    They are all stored in the iPhoto Library.  You would need to examine its contents to see them separately (outside of iPhoto).

    Where is the data file for the address book located, I need to restore mine from backup but don't know where it is to do so.  Putting my Mac Pro onto icloud synching contacts resulted in duplicate and triplicates of the same cards.  I have a few THOUSAND contacts and the last time this happened was on mobile me.  that had a function where you could replace info on the mobile me server with info on the computer.  I see no way to do that on the new cloud.

  • Only sequences, where are the media files?

    I recieved a project that has only sequences in the browser, but in the seqences, the edited clips are there. Where are the media files? I'm used to having the media files in my browser with my sequences. Since I have sequences but no media files, I'm not sure where the media is that the clips (in the timeline)are pointing to. I know where my source files (QT) are. just not sure where the media files that represent that

    If you are working from the same volume as the original projects, or at least a volume with the same name and folder structure then you are fine. If you want, you can select all the medial files in the sequences and drag them to the browser if it helps you to see what you have. Personally, I think if you are not changing any of those sequenced you're just as well to leave it as it is. Are you seeing video when you play those SD sequences? If yes then they are already pointing to the original media. FCP doesn't create its own media unless you render, and even then, it still uses the original in that process. So if you can see the video, you're all set. It's when you see those white clips in the timeline that you have to worry.
