If you do not call Close, the garbage collector .NET Framework will eventually clean up orphaned objects, such as connection objects you mention. But there is an exception in the case of load at the CG will be delayed to allow other higher priority activities to occur. As he falls behind, orphaned connections will be piling up until you hit the max connections or run out of memory. The answer to your question really depends on the load.

If each application is only allowed to have a connection, your code must enforce this policy. Set to max your connection pool size. That is one and only one connection is authorized by the client.

    Anyone know if there are certain restrictions on access to the views v$ through PL/SQL?

    EDIT: http://www.dbasupport.com/forums/showthread.php?t=22299

    Access to the views of $ v seems to be through a role - try giving explicit access to it.

    As SYS, you must grant select permissions on V_$ SQL (V$ SQL is synonymous with V_$ SQL) to your owner of the procedure. Just tested on my system and it allows him to compile.

  • What is the problem with my iMac mid-2011

    Hello

    Need help find out what is the problem with my iMac to mid-2011.

    Yesterday during a reboot it just never came to life.

    On turning the power on, I get the RINGTONE to start and that's it. The screen is totally black. Nothing behind tried with a torch.

    VRAM rearmament so far I tried repeatedly, unplug and plug, all kinds of combinations of keys in the carillon and nothing.

    Connected to an external monitor and shows nothing of too - no signal.

    Any way that I can know what is wrong with it before sending it to the service tech? I suspect bad graphics card but how do you ensure?

    From what you describe, it looks like a hardware issue that Apple will only be able to resolve, but not to despair immediately.

    Read it please get help with graphics issues on external displays connected to your Mac - Apple Support.

    I know that the title and subject are not suitable to your concern, but buried in this document is the following passage that contains three links describing the steps to follow.

    If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.

    If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

    That first, then write again for additional suggestions if you are still having problems.

  • What is the problem with kernel_task?

    Hello everyone,

    What is the problem with kernel_task?

    I explan: Macbook Pro early 2011 LION OS up to date.

    I bought 8 GB on China supplier, CRUCIAL...

    Well, I got a lot of kernel Panic. Usually, he is involved material, taken on my RAM, back is the original, so still have in the kernel_task to 300% CPU monitoring followed up to 500%...

    Well, I went back to a clean install, a manufacturing one, with nothing.

    Wish I 'd' diagnosis of the equipment, never went on, test it on safe mode, disable all extensions, then nothing:

    Sometimes the kernel_task crazy sometimes not...

    Good read a lot on the internet but nothing has worked... I went to the Apple store in DIJON, they do not have diag any hardware problem, and all my App are approved Apple.

    Used to play the eve online thought, therefore, the graphic chipset pourrait was damaged, so when it's too 'hot' the mac gets crazy... but I expected crazy restarts and that sort of thing.

    I bought a manual, there is no french support to the opening of Apple, but found nothing about my question.

    So what?

    I bought something conivient on Support and friability so today he's dead?

    What should do?

    If you still get the panic of the core, thanks to post separate 2 or 3 of the most recent as answers on this.

    Reports of kernel panic: "/ Library/Logs/DiagnosticReports".

    http://support.Apple.com/kb/ht2546>

    http://support.Apple.com/en-us/HT200553>

    The panic report should have "panic" in the name of the file.

    Kernel panics tend to come from 2 sources

    • Material:
      • 3rd party RAM is the most common.  Replace or return the original is usually the solution.  Crucial and MacSales.com were 2 of the most reliable sellers for the initial quality and guest without question of replacement.
      • Broken USB cables or USB devices have turned up as the 2nd most likely material number.  Usually remove all USB devices, or replace the keyboard and USB mouse to see if it's one of those existing.
      • There are a few Macs with graphics chips that have failed.  I don't know that they exist, but do not know what model Mac had these chips.
    • Software
      • antivirus protection.  It is the number 1 most panicked related software cause.  More OS X does not need antivirus, because it has its own built-in protections http://www.thesafemac.com/mmg-builtin/>.
      • Other core 3rd party extensions are a distant 2nd.
      • NOTE: not all 3rd party kernel extensions are causing problems, but when there is a kernel panic, it's the first thing to look at.

    If run kernel_task is often caused by core 3rd party extensions.  It can be caused by an application program, but then the Applications-> Utilities-> Activity Monitor show "As" an application that consumes a lot of CPU, disk IO and network IO in collaboration with the kernel_task using lots of CPU.  If there is no application burns the CPU at the same time, so it is almost always a 3rd special part of the kernel that was originally the use excessive CPU kernel_task.

    Start in safe mode is usually a test to see if 3rd party extensions are part of the case.  But in safe mode is not how you run your system, because it also loads less advanced graphics drivers and other components.  Safe mode is very conservative, but it's a great way to see if the 3rd party software is at fault and have started when 3rd party software panic the system at boot.

    The contributors to the forum long strongly warn against getting 3rd party anti-virus, cleaners Mac and additions increasing.  This class of 3rd party additions have shown time and time again to really harm performance, remove things they shouldn't and cause a kernel panic.  Especially right after an OS X update to a new version.

  • Dell Xps 17 straight pregnant L702x a whistling noise + sometimes it loses volume? What is the problem?

    Hello

    I am faced with an irritating problem, I noticed that my right speaker sometimes will decrease volume, and then after awhile, it will return to normal volume / or I believe it loses low, which means that the sounds of the left speaker stronger, then the right speaker. Last night I noticed there was a crackling sound from the right speaker, it wasn't strong, but when the room is quiet then you could hear it. I don't know if the problem is on the right speaker.

    Can someone please guide me to know what's the problem, my warranty just ran out last month so I have to be on what the problem actually is the first

    James192131
    I didn't notice this before but my helmet is loose, for example if I plug my headphones into the Jack, you don't need no strength at all to stick it in and out.

    Maybe you should look into getting an extended from Dell warranty.

    If you ever decide to work on it, you can get the part with the audio of people parts (parts of Dell specialists). They also have the left/right speakers for $15. Their parts are mainly used, but a guarantee.

    3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
    4. Restart the computer and let the USB controllers get reinstalled.

    Plug in the removable USB device and test to make sure that the problem is solved.

    If the problem persists, go to method 3.

    Method 3:

    This method will install the latest drivers from device to your USB device.

    1. Click the Start button, type Windows Update in the search box, and then click Windows Update in the results pane.
