DB Adapter Polling when database is shut down

Hi all,
I am trying to understand the DB adapter behavior (when set up to poll for new records) when the target DB is shut down. At my customer's site, the target DB is shutdown on Sunday mornings for a cold back-up. This is causing my ESB service to fail - and it does not resume when the DB is brought back up. When I've tested this on my own laptop environment (SOA Suite with Olite and a separate 10g DB as my target DB), it properly resumes polling when I bring my 10g instance back up. I've left it down for over 30 minutes - and it still resumed polling as it was supposed to. Is there a parameter somewhere that tells the App server to give up after a certain amount of time? Or is there something else I can check? Thanks for any help!
Details:
SOA Suite 10.1.3.1.0 on RH Linux
BPEL and ESB Schemas are on Oracle 10g on RH Linux
Target DB is on Oracle 9i on AIX
Cheers,
Lon

Changing the retryInterval and retryCount for that adapter process solved the problem. Thanks. I assume there's no bad side effects if I set this to keep trying for an hour or so? That's how long the target DB may be down for backups.
Thanks,
Lon

    You have following choices to free up space from recovery area:
    1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
    then consider changing RMAN ARCHIVELOG DELETION POLICY.
    2. Back up files to tertiary device such as tape using RMAN
    BACKUP RECOVERY AREA command.
    3. Add disk space and increase db_recovery_file_dest_size parameter to
    reflect the new space.
    4. Delete unnecessary files using RMAN DELETE command. If an operating
    system command was used to delete files, then use RMAN CROSSCHECK and
    DELETE EXPIRED commands.

  • I was using my Macbook when it suddenly shut down, I was updating a program so I had the charger on even though there was still 90 percent of power in the computer. I tried to turn on the computer several times but is not working, what can I do?

    I was using my Macbook when it suddently shut down, I was updating the operating system so I had the charger on even though there was still 90 percent of energy. I tried to turn my Mac several times but it doesn`t turn on, also the green light of the charger is not working, it`s looks like the charger is dead too. What`s wrong with my Mac?

    Try resetting the SMC.
    MacBook and MacBook Pro with a battery you can remove
    Shut down the computer.
    Disconnect the MagSafe power adapter from the computer, if it's connected.
    Remove the battery.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Reconnect the battery and MagSafe power adapter.
    Press the power button to turn on the computer
    To reset the SMC on newer Mac portables with a battery you cannot remove
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.  
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • When i press shut down my mid2010 mbp restarts, please help!

    when i press shut down, my mid 2010 mbp restarts, please help!

    OK, that eliminates a sticking power button, which would have been a possibility if you were using that button to bring up the Shut Down option.
    Does this problem occur when you're running on battery power, on AC power, or both?
    In System Preferences > Energy Saver > Power Adapter tab, do you have "Start up automatically after a power failure" checked? If you do, uncheck it, quit System Prefs, and see whether the problem persists. Post back with results.
    Oh, and since you say this also happens when you select "Sleep" — does it happen when you close the display to put the machine to sleep, or only when you select the "Sleep" command from the Apple menu?

    I was charging and updating my mini ipad last night when it suddenly shut down and will not turn on since then. What do I do to turn it on again?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

    My Ipod Touch have a black screen when an app shut down and I can not shut down the Ipod. The screen is still black and I did the press two buttons solution and it doesn't work. What I have to do now?

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Blue Screen & Restart when trying to shut down

    I've been having this problem the past week or so where when I try to shut down windows, I'll get a little blue screen error after the "shutting down" screen (literally a split second), then a restart of my computer. I can never just shut it down completely anymore, I have to wait for it to restart and then shut it off manually. Now from previous knowledge I know that a blue screen and a restart generally means theres a hardware or software error, but I'm wondering what's causing it to do this. I recently installed an external DVD drive...could that be the problem? I don't know. If anyone has any suggestions on what I can do to fix this, it would be much appreciated. Thanks

    this seems like a different problem than the display whine, but a windows blue screen can happen when a +/- incompatible driver is installed. I don't know if you needed to intstall something with the external drive? Maybe de-install related software and check if there are some update patches from Microsoft.

  • My browser suddenly always opens on the page it was on when it was shut down last and uses tabs even though I have them turned off. I have tried reinstalling.

    I have my browser set to open on comcast.net webpage and to never use tabs. I have been using firefox for years and am very familiar with it. Suddenly it has started opening on the last page it was on when shut down, and has started using tabs. When I delete Firefox from my computer, it still remembers all my settings. I had this problem once before years ago and ended up having to wipe my entire drive to fix it. I would like to avoid a drive wipe this time. I need to know how to get ALL of the browsers information deleted from the registry so I can get a truly fresh install. And yes, I have tried all the normal avenues and am pretty computer savvy. Please help before I go nuts. I am running the most recent version, but going back to older versions didn't help either. Thanks.

    Another possibility is that Firefox keeps crashing during shutdown, and so Firefox is recovering from a crash every time. To diagnose this, you can change how Firefox recovers from a crash: instead of restoring the previous session, it will show a list of what you had open so you can be selective or bypass it altogether.
    Here's where you change that:
    (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
    (2) In the search box above the list, type or paste '''sess''' and pause while the list is filtered
    (3) Double-click the '''browser.sessionstore.max_resumed_crashes''' preference and change the value from 1 to 0 and OK that.
    ''Note: Please don't change any other sessionstore preferences without researching them first.''

  • Does the Iphone 5 log when it is shut down?

    I forgot to hand it in during an exam. Can I somehow proof that it has in fact been shut down during the time of the exam?
    It was confiscated and is still in their costidy.
    It would be awsome, if I could somehow show that it has been shut down during the exam, when I retreave it.
    PLEASE HELP.

    There is a system activity app, but I'm not sure it can retreive retroactive activity, but maybe worth a shot.

  • Help!  contacts disappear when computer is shut down

    Every time I shut down my iMac, my contacts folder completely vanishes. The first time it happened, I didn't know what happened. I rebuilt my address book. Today I had to shut down my computer because I was having a glitch with Safari, and when I rebooted, my contacts folder was gone again.
    I was syncing with Entourage, and the contacts vanished from there as well. Does anyone have any advice or suggestions how to avoid this problem?

    Make sure that you do not use "Clear history when Firefox closes" to clear the "Browsing History".

  • AirPort Extreme powers down when iMac is shut down

    9-month old AirPort Extreme, with two hardwire connections: one to the DSL modem, and one to an iMac. After months of perfect performance and reliability, the AirPort extreme now completely powers down as soon as the iMac is shut down or goes to sleep. It powers back up with the iMac. Logging out the iMac to another user account does not shut down the AE.
    Naturally, we checked the electrical supply for all three devices and they are all plugged into a perfectly ordinary surge supressor strip.
    We're thinking the AE has a hardware failure...but what kind of bizarre symptom is this that it shuts down when it loses signal from it's only Ethernet client?

    This is certainly odd. Have you tried a different port on the AEX?
    It may be best to contact Apple about a warranty exchange.

  • Why does Mountain Lion take a long time to shut down my MacBook Air when I chose "Shut Down?"  Much longer than before the upgrade.

    Mountain Lion takes a long time to shut down.  Much longer then Lion.
