Sessions disconnect at 4PM daily after clock went back 1hr

hi,
DB in our datacenter is having peculiar issue... all the EM and SQLPLUS client sessions gets disconnected at 4PM GMT every day.
it was OK up to Friday 24th Oct......then clock went back 1 hour in UK on 26 Oct Sunday......and this 4PM issue started on Monday 27th.
When i ran ASH report i foudn this event during the time of disconnect
Top Event P1/P2/P3 Values:
Event : SQL*Net break/reset to client
% Event: 25.00
P1 Value, : "675562835"
P2 Value, : "0"
P3 Value : "0"
Activity %: 25.00
Parameter 1 : driver id
Parameter 2 : break?
Parameter 3 : NOT DEFINED
SQL Text: BEGIN EMD_NOTIFICATION.QUEUE_READY(:1, :2, :3); END;
Object : SYS.KOTTD$ (TABLE)
Object id: 335
Tablespace: System
Can anyone help me on diagonising this issue and resolving it? Error that user are getting are ORA-03114 and ORA-03135
Thanks in adv.

I seem to remember that the message "SQL*Net break/reset to client" means an error occurred. I am not sure what you posted is not a sympton rather than a cause.
Any messages in the alert log?
What kind, if any, of trace files are being written to udump and bdump at this time?
Do you have sqlnet logging on and have you checked it?
So far yours is the only post I have seen on an issue like this so the problem is probably related to something specific your shop runs as oppossed to a generic database wide issue. So what application(s) are you running?

  • HT1423 after power interruption -all my folders went back with 3 years dates, jow do i return lost files?

    after power interruption -all my folders went back with 3 years dates, How do i return lost files?

    On what exactly? Your computer?
    Do you have a backup off the machine that's stable?
    Now your files are still likely there, it's just a naming issue or a PRAM/SMC problem for power and a cache corruption issue for the files.
    If you don't have a backup of your files, copy everything you can to a external storage drive and disconnect it.
    Next run trhough this list of fixes, I suspect the SMC/PRAM reset will help with the power issues and the #12 OnyX cache cleaning routine will set your folders right.
    Remmeber after the PRAM reset to set your time and date correctly. Pehaps that is what s throwing off the date on the folders?
    It's really hard to figure your problem out with the information provided.
    https://discussions.apple.com/docs/DOC-3353
    Again your files are likely very much still on the drive, you can recvoer anything as long as it hasn't be secure erased or overwritten by new data yet
    Create a data recovery, undelete boot drive

  • I have itunes directory on an external hard drive and want to direct a new installation of itunes on windows 8 to use it. I tried holding down ctrl and clicking itunes and after many tries got it to work one time. When I went back in later it had reverted

    I have itunes directory on an external hard drive and want to direct a new installation of itunes on windows 8 to use it. I tried holding down ctrl and clicking itunes and after many tries got it to work one time. When I went back in later it had reverted back to a blank version of itunes and I cant get ctrl to work again. Any other ideas?

    This is sometimes caused by a problem with the iTunesPrefs.xml file, normally found at C:\Users\<User>\AppData\Local\Apple Computer\iTunes\iTunesPrefs.xml. Try dragging this to the desktop and trying again.
    Alternatively the problem may be that you have McAfee AV and it is preventing iTunes from updating the same file and thus causing the problem. See Why does iTunes delete my itunesprefs.xml? for details.

  • My battery went dead and I had to plug it in. after several hours I went back to it and it is has an icon that is saying plug in and itunes.  It won't do anything else- nothing. I can't turn it off or or on and I have no access to my phone.

    my battery went dead- I plugged in it.  several hours later I went back to it and it wasn't on. instead the only thing on the screen was a picture of the plug in and the icon itunes on top of it.  I have no idea what that means.  My phone will not turn on even after I hold both buttons. i was told a while back that the i7 program can mess this up and to hold both buttons down to reboot the phone.  I tried this but even this isn't working.  Any ideas?

    You need to do this http://support.apple.com/kb/ht1808

    Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.<br />
    Use "File > Exit" or "Firefox > Exit" if you want to restore multiple windows.<br />
    You can use "Firefox > History > Restore Previous Session" to get the previous session at any time.<br />
    There is also a "Restore Previous Session" button on the default <b>about:home</b> Home page.
    Another possibility is to use:
    * [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

  • How can i start my iphone 5 after it went on safemode and itunes cant help me!! i was trying to update it!!

    how can i start my phone after it went on safe mode while i was updating it!! it says i need to connect with itunes but when i doo it tells me its an error !! i cant use my phone at all!!

    modular747,
    Had same problem, got answer from supprot community and it worked.
    Hold down your power bar (on top) and your Home button (on face at bottom) for about 10 - 20 sec. and your phone will be restored - nothing lost or changed.  Worked like a charm for me 20 sec ago.
    Good luck

  • Lost Mode and Play Sound are "Pending."  However, iCloud indicates that it connected and backed up to iCloud at a date that is 1 week after it went missing.  How is this possible without locking (Lost Mode Pending an internet connection)

    Hi,
    My wife lost her iPhone two weeks ago while on vacation in London (cell service inoperative in foreign country).  Using Find My iPhone app on my device, I activated Lost Mode and Play Sound.  However, both are listed as "Pending," since it those actions require the phone to connect to the internet (wifi only due to no cellular data coverage.).
    We recently returned home and purchased a new iPhone.
    However, when looking to restore the apps/settings from her old phone using a previous iCloud backup, iCloud indicates that the old phone connected to iCloud and backed up the original phone at a date that is 1 week after it went missing.  How is this possible without locking (Lost Mode Pending an internet connection)?
    If the phone was activated and connected to the internet via a wifi signal, shouldn't it immedately lock, show up on the map, Play Sound, and send me an email that the phone has been found?
    I also read somewhere that if running iOS 7, the iCloud website interface enables you to track previous locations, for instance if the phone moves from wifi hotspot to hotspot.  Is that true?  If so, how do I do that?
    Thank you for your time, and have a great day!
    Sincerely,
    - Matt

    just giving this a wee bump as time is of the essence here and i need advice/ answers quick!

    Yes, my telco is an approved carrier. If my phone was brand new, I think so, they opened it in front of me.. I really couldn't remember it was 1.4 years ago. It did seem new.
    Well it says, "_____" cannot be used to unlock this iphone. I've tried both my apple ids but it didn't work.

  • My Game Center went away after the last back-up. How do I get it back?

    My Game Center went away after the last back-up. How do I get it back?

    It's on your iPad somewhere. It cannot be deleted.
    Swipe from screen to screen to look for it.
    You can also reset the home screen layout and the icon will reappear - but the home screen will return to the way that it looked when you first activated your iPad.
    Settings>General>Reset>Reset Home Screen Layout.

    Thank you all for your help!
    I bought a new hard drive and reinstalled everything.
    I got a smart drive USB casing for the corrupted hard drive and connected it to the laptop.
    First it couldn't read any thing on it and it wouldn't run a scandisk. So i run a scandisk on 'my computer' which included the connected smart drive.
    Took a long time ... went to bed after 2 hours and when i got up and restarted the laptop, the smart drive was accessible and i could transfer all my files etc.
    I don't know what it did over night, but it worked.
    I reinstalled the old hard drive to retrieve some program data and it runs on windows again and everything was nearly like before, just the system restore wouldn't run and after a scan disk etc it still won't run.
    great.
    have a nice day

    <Edited by Host>

    Guys thank you so much for the advises and helps.. i went back to Extra store and finally they changed my unit to a new one..Now i can figured out which one has facetime or none, from the box itself at back  it writtens arabic so definetely no facetime and if english, portugese and chinese characters has 100 % with facetime.. I'm so blessed that they agreed to changed my unit to new one. At first the manager opened  four boxes of new unit for me to check if facetime is there and he reassured me there's new batch of iphone5 coming on 2nd day. So i went back and he changed it to new one.. .Now im satisfied..
