Network drives fail (drives used to share databases among multiple computers)​.

I am using databases on multiple computers to store test results for a production line. The computers share info from thier databases with each other using dsn's made with the ODBC Windows XP Admin Tool (Control Panel). This works well most of the time but occasionally one of the network drives fails - I have to disconnect and then use ODBC to make a new connection (a new dsn). Why are the network drives failing? Should I use somenthing else that is more reliable? datasocket? Shared Variable? [email protected]

Gary MavSysInc,
When you say that your program fails, are you referring to the same thing as your LabVIEW Application that is reterieving data? If so, what do you mean by it fails? Is there an error message? Does it Crash? What happens when it "fails"?

  • Using a partition to share files among multiple computers?

    I have a small business with just a few employees and we currently share all of our business files which are hosted on my Macbook Pro.  These files include an Aperture library, an iPhoto library, and a bunch of just plain old files, including a fairly large Filemaker database. I like having these files on my computer so that I can access them quickly (without lag), and this is particularly important for the database and the photo libraries.  And since I am often working 'after hours' its easy for me to be on the move (even if its just a move to my couch!) and still have quick and easy access to the work files.
    However, we're having some major problems with file permissions. Sometimes (and seemingly randomly) employees can't open files because they don't have permission' and often I need to reset the permissions on files my employees create in order to open them myself.  iPhoto needs to "repair" the photo library just about any time a different user opens it up.  It looks like we just lost a couple hours worth of work yyesterday tagging photos in iPhoto since they mysterously dissapeared when I opened iPhoto this morning.
    So we need a solution that will get us around this permissions nightmare.  I read one suggestion about putting iPhoto/Aperture libraries on an external HD and sharing them that way, however, totting a hard drive around might get akward, especially if I am working after hours, and I Don't know that it solves our issue with the rest of our work files.  At this point I would be willing to invest in a Mac Mini server if that would solve some problems, but that would probably leave me with slower access to the files than I currently enjoy.
    So the thought came to me, why don't I partition my hard drive and use half of it for all the work files?  Could I set it up so permissions are ignored on that partitions as is reccommened for the external HD solution?  Are there other solutions, or pitfalls with this solution that I'm not considering?

    Can I partition my drive without whiping it entirely and then having to restore everything?
    Probably.  See #3 in Using Disk Utility.
    Also, the "Alternative Method" mentions using a disk image.  My experience with disk images is limited to those temporary "disks" used when installing new software that are erased when put in the trash or the computer restarts.  Is there such thing as a perminent disk image?
    Yes.  You can create and keep them anywhere.  They're kind of like a disk-within-a-disk.  They have their own format, directories, etc.  For example, some folks use encrypted disk images for their sensitive files.
    There are a few considerations:
    Only one user can access it at a time, so if you use Fast User Switching and one user has it open, others won't be able to use it.
    You'll need to put it in each user's Login Items so it will be mounted at login, per the article.
    The contents will not be backed-up while it's mounted.
    (But, in many cases the iPhoto Library won't be backed-up by Time Machine while the iPhoto app is open, no matter where it is.)

  • Using the same library with multiple computers over a network Use Aperture

    Hi Everyone. I am researching some cataloguing/editing programs to recommend one to my boss, and I was wondering if it was possible to use the same library between multiple computers on a network. Does anyone know if this is possible? This may be what makes or breaks the decision on whether or not to go with Aperture as we need a program that can access a large database of photos on multiple computers.
    Thank you.

    Welcome to the forum.
    You can do it, but...
    It's not supported by Apple.
    Performance won't be great unless you're running a really fast network.
    If more than one person tries to access the Library at one time you're likely to end up with a corrupted database, and there's no code in Aperture to limit access to one person at a time.
    The Library must be stored on an HFS+ volume - don't even try putting it on a FAT32-formatted drive.
    If you want 'proper' multi-concurrent-user network-enabled cataloguing software you're looking into a whole different level of investment than the low price of Aperture - think more in terms of thousands or even tens of thousands of dollars.

  • Can I use a Time Capsule for multiple computers?

    Hello,
    after reading various posts on this forum I am now more more confused than ever : bear in mind that my understanding of computing stuff is quite ... limited, so I apologize if this question seems senseless.
    I have several small capacity external hard drives which I uses for back ups and moving files between my computers (1 desktop (2.16 GHw Intel Core 2 Duo: Mac OSX 10.6.5), 2 laptops) but the result is a ton of confusion and multiple files everywhere. I was therefore thinking of getting a Time Capsule 2T which I would use as :
    - a unique external back up machine for all my computers (without adding any other external drives)
    - a wifi modem-router
    Before investing that much money, can anyone tell me if the Time Capsule is indeed appropriate for the above uses, particularly being able to program all 3 machines to wirelessly back themselves up on the scheduled basis.
    When I started seeing questions about adding USB driven external hardrives It made me wonder if i had gotten the purpose of the TC all wrong.
    Thank you for your patience!:=)

    Yes, that's exactly what it was designed for.
    You can put other data on a Time Capsule, besides backups, but that will cause some conflicts, sooner or later. See #Q3 in [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum).
    When I started seeing questions about adding USB driven external hardrives It made me wonder if i had gotten the purpose of the TC all wrong.
    You can do that as well.
    One purpose is, if the TC isn't large enough to back up all your Macs, you can back some up to the TC's internal HD, others to the USB drive. It varies widely depending on how you use your Mac, but a "rule of thumb" is, TM needs 2-3 times the space of the data it's backing-up, to be able to keep a reasonable "depth" of old backups for you.
    Another is, if you want other data available over the network, you can put it on the USB drive to avoid the hassles in #Q3. And, since you can partition the USB drive (unlike the internal), you could use one partition for backups, another for other data.
    |
    There is an alternative, however, that you might find more attractive (and less expensive), since you do have a desktop Mac, and I assume you already have a wireless router.
    That's to connect one or more external HDs directly to the desktop Mac, and back it up directly to that drive (or a dedicated partition on it).
    Then back up the laptops over your network to a different partition on the same drive, or a different drive, via sharing. See #22 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
    For moving files around, you could continue to use a small external HD, or use sharing over your network.

  • Using single iTunes library for multiple computers

    With the new Airport Disk utility, can I attach an external hard drive with my iTunes library and have multiple computers point to that library as the library for each?

  • Sharing in-memory database among multiple processes

  • Using iTunes/Ipod mini on multiple computers (many questions)

    Hello I recently purchased another computer for myself. I would like to use iTunes and my ipod mini on this computer but I would also like to continue to use it on my family's main pc. Is this possible? Do I have to worry about that deauthorization of computers, or the license, or is it fine to use on two pcs? I just don't know how all that stuff works but I think I remember something about having iTunes on one pc only.
    Now for the second part of my questions. How do I actually go about transfering iTunes and my ipod to another pc? Do I just install iTunes like normal and transfer my files using an external hard drive? My family pc will remain as the main one for now but eventually I'll switch it to my laptop. I don't care about playlists and song ratings because I don't bother with that. What I want to do is simply have the music that's on my family pc put onto my laptop. I have bought an external hard drive so I could transfer the music without much problems.
    Finally can I switch between my laptop and home pc? I mean can I use my mini from my laptop and then later update it from my home pc and do other things like that. I'll use the songlist from my home pc for now but eventually my laptop will become my main one. I know I read something about clicking no if I want to change the music library when plugging in my ipod to another pc. Do I have to keep both iTunes updated to the same version and the songlist the same? I'm wondering if there will be any conflicts between the two.
    I'm sorry about how confusing this all is and the many questions I have but I hope somebody can help out. Thank you.

  • Using BT Keyboard / Mouse with multiple computers

    Hey everyone - happy holidays!
    I have a quick question (or so i hope) regarding the use of a Apples Bluetooth keyboard and mouse. I have two computers a Mini and G5, I currently have 2 displays and would like the option to be able to switch my second display to my Mini.
    This I can accomplish with a KVM switch, the drawback is I have the BT keyboard and mouse paired with my G5 - is there a method of pairing my interface with both machines but have the ability to switch from one system to the other?
    Thanks for the help. Jim.
      Mac OS X (10.4.3)  

    I do not believe it is possible to pair devices like mice and keyboards to multiple computers. Its a security risk hence the reason behind "pairing". There may be a software solution such as:

    But I have not used it or looked much into it.

  • Can you use the Time Capsule as a wireless drive to share music on multiple computers

    Does anyone know whether you can use the time capsule almost as a nextwork drive of sorts (i.e. to share Music etc amongst a few computers)?

    The TC is a dumb hard drive inside an apple extreme router.. with a couple of knobs on.
    It has no media servers.. and very little flexibility.. indeed it serves files.. AFP or SMB.. and that my friend is that.
    So if you want a media server in the network..then a mini is a better proposition. At some point, with sales of ssd laptops soaring and space on these devices at a premium, Apple is long overdue on a revamp of the TC.. it is really either time to drop it or to create something a lot more powerful.. the mini might be a cheap computer but it is not really a file server.. having so little internal disk space and lacking external connectors unless you are rich enough to buy thunderbolt.

  • How do I use one iPhoto library on multiple computers?

    I have a laptop and my wife has a laptop...how do we share one commone iPhoto library? How would that work with syncing our iPhones?
    I'm thinking we should get a shared network drive at home...but then our photos would not be available when we're not home - right?

    The only way to do what you want is to put the Library on a USB/Thunderbolt disk and plug it into each Mac as required.
    I'm thinking we should get a shared network drive at home
    You can't put iPhoto on an Network location.

  • How to use airport time capsule with multiple computers?

    I'm sure there are some thread about this but i couldn't find it... so sorry for that but hear me out! =)
    I bought the AirPort Time Capsule to back up my MBP
    And so i did.
    then i thought "let give this one a fresh start" so i erased all of it with the disk utility and re-installed the MBP from the recovery disk.
    I dont want all of the stuff i backed up just a few files and some pictures so i brought that back.. so far so good.
    Now i want to do a new back up of my MBP so i open time machine settings, pick the drive on the time capsule and then "Choose" i wait for the beck up to begin, and then it fails.  It says (sorry for my bad english, im swedish haha) "the mount /Volume/Data-1/StiflersMBP.sparsebundle is already in use for back up.
    this is what i want:
    i want the "StiflersMBP.sparsebundle" to just be so i can get some stuf when i need them. it's never to be erased.
    i want to make a new back up of my MBP as if it's a second computer...
    so guys and girls, what is the easiest and best solution?
    Best regards!

    TM does not work like that.
    If you want files to use later.. do not use TM.
    Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.

  • Share libraries  among multiple users on the same Macbook.

    I want to share the IPhoto library between two users (A and B) of the same New Mac Book (Oct 08') that would be located in the Users/Shared folder.
    I tried to follow the steps described in article HT1198 of the Mac Support dated Oct. 8th, 08' (http://support.apple.com/kb/HT1198) but it deals only with the issue of sharing a library that is located on an external HD.
    I did the following:
    1. Logged under A account and moved my empty library to the Users/Shared Folder.
    2. Right clicked on above-mentioned library to grant Write & Read privileges to account B
    3. Opened IPhoto whilst pressing Opt. and selected above-mentioned library (in Users/Shared folder).
    4. Logged out of A and logged in as B.
    5. Opened IPhoto whilst pressing Opt. and selected above-mentioned library (in Users/Shared folder).
    6. Quickly the following error message showed up (and kept on showing up):
    'An error occurred while trying to save you photo library. Some recent changes may be lost...'
    All changes made to the library under account B where indeed not saved and did not appear when I accessed IPhoto under my account A.
    Please note that when I Chose File > Get info on my external HD and/or Shared folder and/or IPhoto library, I could not find the 'Ownership & Permissions' menu nor the 'Ignore Ownership on this volume'. Only a 'Sharing and Permissions' was available with no other option/detail.
    I just switched to Mac last week and I have tried to solve that issue (that seems easy to solve) repeatedly in vain. It is hard to get help in English here in Japan. Any help will be highly appreciated.
    Thanks.

    Sharing the iPhoto Library from the Shared Folder is not supported on 10.5 and involves a trip to the Terminal. *I strongly suggest that if you're not confident in the Terminal that you use some other version of sharing.*
    There are two ways to share, depending on what you mean by 'share'.
    If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
    Remember iPhoto must be running in both accounts for this to work.
    If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc. then:
    Quit iPhoto in both accounts
    Move the iPhoto Library Folder to an external HD set to ignore permissions. You could also use a Disk Image or even partition your Hard Disk.
    In each account in turn: Hold down the option (or alt) key and launch iPhoto. From the resulting dialogue, select 'Choose Library' and navigate to the new library location. From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
    However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.
    Finally: If you’re comfortable in the Terminal, and understand File Permissions, ACL’s etc., some folks have reported success using the process outlined here . (Note this page refers to 10.4, but it should also work on 10.5). If you’re not comfortable with the terminal, and don’t know an ACL from the ACLU, then you’re best doing something else... Oh, and the warning about simultaneous users still applies.

  • Using same mail certificate on multiple computers

    I have a MacPro and a MacBookPro. I could just retrieve my Thawte email certificate on both and they would be usable to encryption and signing on both computers. This renewal though only the requesting computer (the MacPro) shows them up in the 'My Certificate' section with both the public and the private key - downloading the certificate with the MBP just adds it to the 'Certificates' section with just the public so I can't sign or encrypt from there.
    How is it keying them to the particular machine? I of course want what I previously had: a signed email account not tied to a particular originating machine.
    Is it something simple? Do I need to transfer Thawte certificates too?

    Hi,
    This is what i did for installing wildcard certificates:
    On the OS of the sap server, log in with the sapadm account.
    Open a command prompt:
    make a backup of your sec directory in drive:\usr\sap\<SID>DVEBMGS00\  (just to be sure)
    cd to drive:\usr\sap\<SID>DVEBMGS00\exe
    >sapgenpse.exe import_p12 =p SAPSSLS.PSE location\to\the\certfile.pfx
    It will ask you for the pin, and to overwrite the file, answer yes.
    Now copy the new SAPSSLS.PSE to a desktop that has sapgui
    Login with the sapgui and run transaction strust
    Select import from the PSE menu and open the SAPSSLS.PSE
    Then again goto PSE menu  and select Save As
    I saved it twice, once in System PSE  and then again in SSL Server
    For me SSL is now working without problems on a couple of servers.
    -small update-
    You can check internal servers using the certificate utility from digicert https://www.digicert.com/util/
    It has the option to specify port numbers, usefull for internal web services.

  • Using One iTunes Library on multiple computers.

    Hey guys,
    I've currently got my iTunes library saved on a Time Capsule and use it with my mac mini.
    I want to be able to use the same library on my macbook pro. have set up iTunes on both computers so that it looks for the library on the Time Capsule so at the moment both machines can play all the media.
    However if i buy track using the mini and add it to iTunes it saves it in the right place and plays fine but how can i update the library on the macbook as so it can see the new songs that have been added?
    Any help would be greatly appreciated
    Kind regards

    Another detail with this setup is that if you've got an iPod or iPhone that you want to load music to, you'll need to connect it to the computer that is the 'host' offering the music library for share. If you use the 'client' computer, then it won't let you install your mp3s to your iPod from the 'shared' library on the other computer.
    In my setup, which is similar to what you're describing, it looks like iTunes lets me connect my iPhone to either computer and install mp3s.
