Connection Pooling much faster but eventually brings down the site

Hello,
We are running Oracle 11g, with ODP.net. When we have connection pooling turned off the site is very slow. When we turn it on, the site runs very fast, but will all of a sudden slow down to a crash and require an IIS restart. (We will receive many oracle connection timeouts). After checking the Event Viewer, the site crash seems to coincide with a stored procedure crash, though we aren't positive that this is the case. We are running IIS on windows 2k3 asp.net 3.5.
Any assistance is greatly appreciated.

It sounds like you're describing a connection leak, and those are usually the result of code not cleaning up after itself properly. Make sure you're calling Dispose on all your objects as soon as you're done with them so the GC can free up the resources.. OracleConnection, OracleCommand, OracleRefcursor, OracleClob, OracleXMLType, OracleParameters, etc.
Also make sure you're up to the latest version of ODP and client. There were some issues in earlier versions where an access violation could leave a hung critical section and hang the pool.
Hope it helps,
Greg

    It's not good to shut off the power forcibly, right? (I dun know what else I can do...)

    Hi Min! I'm having exactly the same issue - have been putting up with it now for months but have finally had enough! Every single time i eject either my iphone, ipad or ipod nano, itunes freezes up, the computer becomes unresponsive. Usually i can use the mouse to highlight icons but the system doesn't respond, the keyboard doesn't work and I have to do a hard reset.
    Arrrrrggggggh!!!!!!! lol

  • ITunes causing Beachball of Death bringing down the whole computer.

    My iTunes problems started about 3 months ago. Whenever I use iTunes (playing a song, downloading a podcast, syncing my iPhone, etc...) I get the beachball which never goes away. iTunes finishes playing the song that is currently playing but I am not be able to do anything with the program itself. Initially for about 15-20 seconds I can switch to other programs like the Finder or Safari but eventually those become frozen with the beachball as well. After about 20-25 seconds the whole computer locks up. I have tried to force quit but cannot even get that dialogue box to do so. I eventually have to power down the computer manually (switch in the back) and turn it back on. This problem does not happen every time I use iTunes but most of the time. Tends to happen when I am trying to do multiple things. I can sync my iPhone usually without a problem. But it seems if I try to play a song as well then I will get the problem. I am running ITunes 8.2.1 on Mac OS X 10.5.7 on an iMac 3.06 Ghz Intel Core 2 Duo with 4GB of ram (installed by apple). This issues only happens with iTunes and no other program.
    What I have already tried to fix the problem without benefit --
    1. Delete the iTunes Library and rebuilding it (multiple times).
    2. Reinstalling iTunes and upgrading to the latest version.
    3. Using the Disk Utility to repair the Disk Permissions and Repairing the main Disk of the computer where the ITunes Library resides.
    4. Checking the computer for viruses (Virus Barrier X5)
    5. Reinstalling Leopard and then upgrading back to 10.5.7
    6. Bought Disk Warrior -- installed it and Leopard on backup external HD and checked the main HD of the computer for issues with Disk Warrior. It fixed a few issues like permissions but nothing that fixed the problem.
    7. Deselected Movies, TV Shows, Audiobooks, Genius, Radio, iTunes DJ and Ringtones (I need Music, Podcasts and Applications) from the General Prefs -- made it faster but did not fix the problem.
    8. Deinstalled DIVX and Flip4mac.
    My computer almost never froze before these past 3 months and I was real proud of that. Now I am just frustrated. Scanning the internet shows similar problems but not exactly the same. I am out of ideas. I will be eternally grateful for any other ideas that might lead to a fix. I am trying to avoid backing up and then wiping the HD and doing a clean install.

    Same problem here. Jumped through all the hoops. This is my new, thought-it-would-be-a-real-efficiency-boost audio production machine. I've lost soooo much production time dinking around with this.

  • Does adding 100Mbps Switch bring down the speed of a 1000Mbps network?

    I have a wired Airport Extreme network where a 1000Mbps Ethernet switch in one room adds connections to other peripherals.
    Now I want to add a switch in a different room for wired connections that are now operating wirelessly. And I have available a 10/100Mbps Ethernet switch. If I add that to the network do I bring down the speed of the entire thing? I realize that the connections directly from that 2nd switch can only be 100Mbps.
    But will I affect the speed of the other connections?
    Thanks in advance.

    And I have available a 10/100Mbps Ethernet switch. If I add that to the network do I bring down the speed of the entire thing?
    No

    Correct

  • B520 - how to bring down the monitor contrast?

    Brightness control in the front panel are not enough.
    the backlight is too much for me to handle
    Does anyone know how to bring down the contrast even more?
    thank you.

    I'll clear this up a little...
    NVIDIA Controls does not have any control over the lamp / backlight on the screen. You can turn down
    the gamma / brightness / contrast, and you may think you see it darker.
    YEEEEEEES. it's dark but the intensity of the backlight is still there. You can feel it from miles away.
    I chose Lenovo over ASUS just because of the GT555 option, and it was the worst mistake ever.
    Asus Et2700 series do have Contrast/Brightness controls for the screen in Values from 0-100.
    You can turn the screen completely dark if you want. Asus have never let me down, but thanks to my greed
    always wanting more, thought i would never feel complete unless i had the gt555.
    This is what happens when you fall for the marketing agenda.
    Fortunately, i sold it already. And this would be the last time i'll purchase something from lenovo.
    I'd like to think this is something that they just never thought. WRONG!!!. They know. they do it on purpose.
    That's their way to make you feel incomplete, so you can start chasing for something else and fall again
    in the marketing agenda.
    There's always a way to make an "ALMOST PERFECT" product, the worst nightmare for you.
    they have done this for years, since the beginning of times.
    Let's not forget about the SATA performance issue in H67/P67 chipsets:
    http://www.pcstats.com/articleview.cfm?articleID=2589
    the B520 is one of the lines affected and lenovo did nothing about it.
    And please let's not forget about the Trojan that got infiltrated in the drivers disc
    for the B Series Line.
    Hopefully, your campany will get a FORMAT C: by the end of this year.
    arrivederci.

  • How to upload files in cluster without bringing down the cluster.

    Hi,
    Here is my problem:
    My weblogic portal 7.0 application should run in 24x7 environment. The production
    system is running in a cluster mode with external staging. Both the managed servers
    are pointing to the same application sync database.
    So to give a solution to this problem, we are trying to bring down one managed
    server down and apply the patches into that managed server without bringing down
    the other. Since webflow files and entitlements needs to be synchronized with
    the portal database. If we perform a sync on the portal database, there might
    be a chance that it might corrupt the existing portal database state. Our deployment
    would not be complete unless we perform a sync on the other managed servers. So
    we could not able to update the latest pathces into the cluster without bringing
    down the cluster.
    What I would like to know is "Is there any work around to get rid of this problem?".
    I would be delighted if any one provides the solution.
    Thanks & Regards,
    Ratnakar

    Hi Ratnakar,
    When you perform sync you do it against the admin server which in turn does it
    to the managed server. If you want to apply any changes to webflow you can do
    it on the live system itself. I mean apply the new webflow and entitlements and
    do the sync on the live system. Also while doing sync there are two modes. One
    mode will sync only the modified changes and the other will apply all of it. You
    can opt for the first option by which you can sync only the modified changes.
    This may bring a small disturbance but it will be unnoticed.
    The other option is to have two separate domains(each having one admin & one or
    more managed servers) which may be having two separate portal databases. In this
    way you can apply patches to one domain while other domain may provide the service.
    Regards
    Shaan

  • HT3576 I have many apps where i must swipe down and it constantly brings down the notification screen. Is there anyway to disable this or activate it a different way because this really bugs me.

    I have many apps where i must swipe down and it constantly brings down the notification screen. Is there anyway to disable this or activate it a different way because this really bugs me.

    I don't have that problem.  Perhaps I touch the screen lower when I wipe down?  I don't know for sure but there's got to be some difference in the way that we wipe down.  you might wish to do some experimenting.

    Options for when an iOS device gets locked because of forgotten passcode:
    Restore (and reset passcode) on your device by connecting it to the last computer to which it was connected:
    iTunes: Backing up, updating, and restoring iOS software - http://support.apple.com/kb/HT1414
    If you cannot connect it to the computer to which the device was last connected (or the device was never connected to a computer) you will have to use recovery mode to completely reset the device, losing all data:
    iOS: Unable to update or restore - http://support.apple.com/kb/HT1808 - recovery mode (e.g., cannot connect to computer last used to sync device, iTunes still asks for a password)
    If recovery does not work there's:

  • Text is broken when scanning UP the page; but good scanning down the page; why?

    Text is broken when scanning UP the page; but okay scanning down the page. The text looks like a shot gun has been fired through it. It used to be good both ways until the last update. This is not a problem in any other program including Internet Explorer. I have an image to show you but there is no link here to attach.
    After clicking Allow I got ..........The add-on could not be downloaded because of a fault at the support site.

    Try to create a new Boolean pref on the about:config page via the right-click context menu with the name layout.paint_rects_separately and set the value to true and leave hardware acceleration enabled.
    See comment 414 in bug 812695:

    HI again Andy,
    The last message had some more stuff in between the "Hello" and "Regards" - I have no idea what happened to it. But nevermind...
    I started up the Mini with the modem in one usb, and the speaker system in the other (M-Audio Sonica Theatre) - I have one of the Minis that have only 2 USB (and one FireWire) ports. The firewire has the external drive connected to it.
    So far, as I"m typing this, I AM able to be online and use iTunes simultaneously. (both SaFari and iTunes respond slower than if I was using only one or the other, but they ARE actually working - in addition to having Adium running) - So I think what you suggested ( that is was something wonky was the USB hub) was a correct, yet assessment.
    Would you have any reccommendations for USB hubs? The only thing that I have connected to the hub under normal circumstances that would be constantly "running" would be the RadioShark (even though the Radio soft isn't playing - the blue light on the RadioShark is always on) - and the speakers naturally. Everything else is of the occassional variety - iPod Sync Cable, Dual Layer External DVD Burner, and a "pass thu" to the USB ports on my Hard Drive Enclosure (which had been unplugged before the problem was noticed). The hub I current use is the
    Kensington DomeHub USB 2.0 (7 ports) Weighted Hub 33118 http://www.amazon.com/Kensington-DomeHub-ports-Weighted-33118/dp/B0002FHENE/ref= sr16/002-4275642-8664817?ie=UTF8&s=electronics&qid=1187848108&sr=8-6
    which (I thought) worked better than the "throwaway" ones I had used previously.
    You think it is the hub or something connected to it that may be causing the problem?
    Regardless, thank you for your time, and I hope to hear from you soon.

  • Can i make a button change anchor link when you scroll down the site?

    I am trying to make a scroll site.. and i have navigation buttons on the right, a full menu, but also a "1 topic up" button and "1 topic down" button.
    Is there any way that i can have those buttons change anchor link when you scroll down the site.
    Example:
    I am at home, then i press "1 topic down" and gets scrolled to the next topic on the website, but then i cant make the button change to link to the anchor below that, so the button becomes useless after that 1 press.
    Is that in any way possible in Muse to make it change link?

    Hi
    You can try to create different buttons on page positions where down scrolling will be active with separate button actions. For example you click on "I topic down" , page scrolls and there is another button placed with "Next Topic down" , on click this would scroll the page more and similarly along the length of page.
    Button with anchor link scrolling down the page cannot be used for different anchor links, creating different buttons with anchors is the solution.
    Thanks,
