TNS name resolution mystery - has anyone seen this one???

'Afternoon everyone,
Has anyone seen a problem like this? I'm trying to access a (remote) database from a PC. I can successfully test the connection to the DB via the Net8 Assistant, but when I try to get there via sqlplus (with the same service name), I'm getting an "ORA-12154 - TNS: could not resolve service name" error.
Huh?
Thanks,
Len DiMaggio

It seems you have multiple tnsnames.ora files. You can set TNS_ADMIN to point to the oracleDB home and it should be ok.

  • My iPad will not connect to a computer with the cable which  means no updates or down loads. I have tried new cables and different computers. Has anyone seen this before?

    Has anyone seen this issue before?

    Possibly. Do you have other devices and will they connect?
    One possible thing that it could be is that the USB port on your iPad has gone bad. It happened to mine. Couldn't sync, could barely charge (it said 'not charging' even when plugged into the wall)
    I'd take it to the apple store, see if they can replicate it, and if they can, then they can diagnose it. Just back it up before you go, in case they do exchange it.

  • Itunes doesn't display graphics, only text, has anyone seen this?

    Just loaded iTunes 10.5 on Windows...only TEXT is displayed...has anyone seen this?

    I have this exact problem, and it occurs on every device I own: iMac, Macbook, iPad, Win 7. The explanation for the issue is that the stylesheet isn't coming over (.CSS).
    Because it occurs on every device in my house, I'm assuming there's something in my wireless router configuration that's causing it. I haven't found the issue yet, but I'm digging through my modem configuration to see.
    go to either http://192.168.0.1 or http://192.168.1.1
    That's your modem's IP address. If you can figure out what's in the configuration that's causing it, please post back.

  • Has anyone seen this display problem?

    I even changed my video card and still had the same issue? has anyone seen this or know how to fix this issue?
    I tried to show a screen capture but didnt have any luck but the issue is alot of my icons are showing pink lines on them and when in certain application and safari the pictures are showing up all pixelated with pink and green pixels instead of displaying the correct image? is it possible the AGP slot is bad? i just upgraded to 10.5.8 hoping to correct the problem but no luck. Also this is a Power PC 1.8 ghz.
    Thank You

    I wasn't notified that you asked me a question or that there was a new post on this topic. I should have been, that bugs me.
    Anyhow... Mr. Ah
    The problem that some people, mostly with a certain video card, were having was when they updated from 10.5.4 to 10.5.5. For many of them the problem went away when they went through the hassle of reverting back to 10.5.4.
    Did you +just recently+ update to 10.5.5? If you have, then their fix is for you too, going back to 10.5.4. If you have had 10.5.5 installed for a while now, and this just started happening, chances are good that it is your video card, or perhaps something affecting it like dust and dirt like DP says above.
    If you have another start up drive, firewire or internal, and you had enough space on it you might consider installing a previous OS 10.5 on there and start up from it. If the problem went away you would know it's 10.5.5. Perhaps even if you started up from your OS disc the problem might go away and again you'd know it was 10.5.5. Apple was made aware of the problem on some machines and said they were going to come out with a fix, but I don't think they ever did.
    Post back and say what the situation is, especially if you just recently updated to 10.5.5.
    And post back with what kind of G5 you have, look in the "About this Mac" window.
    Your card may be dying, but on the other hand it might be as easy as pulling it out, blowing it out, and putting the card back in again.

  • Problems with Apple ProRes 4444 and alpha channels in Motion 4 after upgrade to Snow Leopard.  Has anyone seen this?

    We've just now upgraded from Leopard to Snow Leopard and are having a problem with Apple ProRes 4444 and alpha channels in Motion 4.  A clip with an alpha which keyed perfectly before the upgrade, now will not key.  If I convert the clip to the Animation codec, it keys perfectly.  If I export the Motion project as a ProRes 4444 self contained movie, it will key when brought into FCP 7 but if I import the project into FCP 7, it will show the key in the viewer but not the canvas.  Has anyone seen this or have any suggestions on how to correct this?  Is it a bug? 
    Thanks,

    Motion 4.0.3
    It just doesn't seem to recognize the alpha at all. 

  • Has anyone seen this behaviour of AccessHW In Port?

    Yesterday I was trying to check the operation of a plug-in PCMCIA parallel port, specifically I wanted to know if there were any timing issues with this device on an XP machine, so I thought I would try the AccessHW In and Out functions in Labview. I installed an old copy of Labview 6.1 (It was 5:50PM and I wanted to do this fast!) and tried it.
    Reading the memory location where the device's status port was supposed to be just returned zero. Strange, I thought, so I tried some other addresses in the I/O range. I got zero from every single one. I tried the same on my own laptop, which is also XP, and I was getting sensible numbers from addresses in I/O space.
    Has anyone seen this behaviour? The machine has McAffee on-access protection running, which cannot be disabled (company IT policy), and I have a suspicion that this might be blocking accesses to low memory, is this possible?

    Sorry... my mind is not working well this morning   You had mentionned that in your original post and the fact that it is a PCMCIA parallel port.
    As for the address location, I have seen addresses in the 0x2000 region for add-on parallel ports (not PCMCIA).
    I haven't used a PMCIA device with Win-XP.  Does the address info for that port appear under properties when you look at the HW devices within the Control Panel's System.  From what I can recall, you can change the PCMCIA serial port number within the HW device, so maybe the properties will list the address.. 
    Have you checked this?
    RayR.

  • Has anyone seen this MacBook Pro 15" 2008 problem before?

    Hi. My MacBook Pro has developed a fault whereby a horizontal line appears on the screen, the mac freezes then a host of vertical lines gradually appear on the screen until it is obscured. Something similar happened in May last year and Apple charged me over £300 to repair it, replacing the 'mother board'.
    I have so far taken it into the Apple shop twice in the last week (a two hour round trip). Both times they have opened it, cleaned it and declared it fixed. This time it lasted about an hour before happening again, although this time at least I've been able to restart it.
    Has anyone seen this before, or have any advice about how best to proceed?
    I have put a video of the symptoms here:

    Thanks for reading. This is my first post so apologies if I've rambled a bit!

  • Has anyone seen this problem? :(

    Hey Everyone,
    I picked the new white 30 gb ipod video up yesterday. I opened it set it up and transfered all my vids and music. Now my problem is the clickwheel. It scrolls about 200 (literally songs at a time and is not acurate with the amount of contacct i have with it. I tried resetting, and now restoring. What shouold I do? Has anyone seen this problem yet?
    Anything helps,
    J.Martin

    Sounds like a strange HW problem. Before you return it, I'd try a Restore, resync, and check it. If it STILL does thast, you need to check with Apple Support.

  • HT4528 The icons on my iphone have all changed to large and I cannot change it back to normal view. Has anyone seen this happen?

    My phone's display has changed as if it were stretched like we can do with photo's except it affects the whole phone. It won't go back to a  normal display even after shutting it off and restarting. Has anyone seen this and  how did you resolve?

    Thank you...this did the trick. I had forgotten about that zoom feature. Now I will ALWAYS remeber it!
    Thank you,

  • Pop-up window with an attempt to open a URL - has anyone seen this?

    I was browsing a website for music lyrics when a suspicious pop-up appeared, along with a very small browser window (about an inch square on the screen). This has happened twice even though I have pop-ups blocked.
    The pop-up had the Safari icon and looked like a standard mac window. The text contained the following:
    <edited by host>
    Antivirus 2009 will perform a quick and 100% free
    scan of your computer for Viruses, Spyware and Adware.
    Do you want to install Antivirus 2009 to scan your
    computer for malware now? (Recommended)
    There is a cancel and an OK button at the bottom.
    The small browser window appears to be contacting the onlineprivatescan.com URL
    I did a force-quit because I did not want to click either button.
    I reset Safari, and ran the DNSChanger Removal Tool
    from macupdate, but it didn't find anything. I have not loaded codecs from any websites and I had just completed the latest Apple updates for OSX, Quicktime and iTunes before this problem occured.
    Has anyone seen this? Is this serious? I've never had any problems with Safari before this.

    Mac OS X 10.4 Tiger automatically checks your downloads for malicious software and content that could harm your system or collect information from your computer. You can read more about that here:
    http://support.apple.com/kb/HT2340
    If you feel you need added protection, read on:
    SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
    http://macscan.securemac.com/
    The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X. Called DNSChanger Trojan and also known as OSX.RSPlug.A Trojan Horse, the software attacks users attempting to play a fake video file.
    Upon attempting to play the video, the victim receives the following message:
    “Quicktime Player is unable to play movie file.
Please click here to download new version of codec.”
    Upon running the installer, the user's DNS records are modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's DNS records stay modified on a minute-by-minute basis.
    SecureMac's DNSChanger Removal Tool allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
    There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac. A white paper has recently been published on the subject by SubRosaSoft, available here:

    Also, beware of MacSweeper:
    MacSweeper is malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer. It is the first known "rogue" application for the Mac OS X operating system. The software was discovered by F-Secure, a Finland based computer security software company on January 17, 2008

    The latest news on the subject, from July 25, 2008, is:
    Attack code that exploits flaws in the net's addressing system are starting to circulate online, say security experts.
    The code could be a boon to phishing gangs who redirect web users to fake bank sites and steal login details.
    In light of the news net firms are being urged to apply a fix for the loop-hole before attacks by hi-tech criminals become widespread.
    Net security groups say there is anecdotal evidence that small scale attacks are already happening.

    Ah yes school boy error there out of frustration and discontent..
    My issue is with music/apps/films etc not downloading from iTunes / App Store.
    They initially fail and message is displayed stating unable to download / purchase at this time, yet if I retry it says I've already purchased (?) or alternatively I go to the purchased section and there they are waiting with the cloud symbol..
    However some items get frozen in the download window and cannot be retried or deleted. Message appears stating to tap to retry, but even if you stole every bath and sink in the uk you'd still not have enough taps.
    I post here as the iTunes guys are useless in there 'help' and have only advised posting here or phoning apple, at my expense, to explain a problem that could be rectified by forwarding my original email to a techie. However the tech team apparently don't have an email address as they're from ye olde Middle Ages..!
    Anyways I digress.
    So I tried sync to pc, but instead of showing the file as ready to listen/use/view, the iCloud symbol shows and I'm back to square one as the item is unable to download..
    At frustration station waiting for a train from pain...
    All my software is up to date, and had all worked fine prior to the last big iOS update that resulted in all the changes in display and dismay.
    Answers in a postcard :-)
    Much love
