How to prevent the registry REMOTE LISTENING on SCAN LISTENER

Hi all

Oracle 11.2.0.3 database

How to prevent remote recording on SCAN listener?
I need to know if there is a way to prevent a grid of the proceeding on the listener by using the parameter remote_listener without affecting the incoming client connection.

These setting below is not sufficient to meet my tests:
tcp.validnode_checking = YES
tcp.excluded_nodes = {list of IP addresses}
tcp.invited_nodes = {list of IP addresses}
The parameters tcp.excluded_nodes and tcp.invited_nodes deny and activate specific IP addresses client to make connections to the Oracle listening port.

    Firefox creates files of 'file' in C:\Users\LeRicain\AppData\Local\Mozilla\Firefox\Profiles\dnm04rk5.default\cache2

    How to prevent the creation of these files in Firefox

    Here are the files from cache. Basically, it takes Web sites that access you a lot and records bits of them so they'll load faster the next time you visit them. FOR EXAMPLE if you visit Google.com much, Firefox will save some elements of this page in the cache so that the next time visit you Google.com, it will not have to re - download.

    Download updates but let me choose whether to install them - if you select this option, Windows will download the updates on your computer, but not install them automatically. If you want to install updates, then you must install them manually. You should only select this option if you have a reason to not install updates automatically. Only advanced users should use this option.

  • How to prevent the OSB 11g to change original prefixes xmlns?

    Hello


    Could someone tell me how to prevent the modification of the xml namespace that I have carefully specified in the WSDL and XSD OSB file?

    By example, if I deploy wsdl file beginning with

    <soap:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/"> ...

    Then I get to the BSO for the same wsdl wsdl file is something like

    <WL5G3N0:definitions xmlns:WL5G3N0="http://schemas.xmlsoap.org/wsdl/"/>


    He renames "SOAP" to "WL5G3N0".  This name change similar to most of the other namespace in the WSDL and XSD files xml prefixes.  This OSB causing to use for a purpose limited in our environment.  We simply turn this renaming feature off (or find different technologies of accommodation... ).


    So I hope it's possible to disable and someone knows how, in the community of Oracle users.  Could someone tell me if it is possible and how to disable the prefix renaming in OSB?


    Thank you

    or at least there is no known way to get that off, right?

    I'm not an employee of the Oracle, so I can't say with 100% confidence. I don't know a way, and I'm sure that the path does not exist.

    thinking of using 'engine for stateful service' Oracle SOA for this is very bad...

    It's not so bad. If you do not service calls in the Middle, then BPEL is not to dehydrate State, making it more or less stateless.

    DataContractSerializer seems to be picky and all pending schema corresponding to certain prefix text

    It's weird, but the code generators are a common source of bugs in SOA :-)

    Good luck!

  • How to prevent the opening of the popup submenu of mx:MenuBar during its events mouseOver/rollOver?

    I'm using a component mx:MenuBar with the xml data to a menu. The basic behavior as I see is, first by clicking on the top level menu item (IE on the horizontal bar), pop-up windows submenu opens. Then without clicking anywhere, if I have the mouse on / roll on the horizontal menu bar, the pop-up menus under other top level menus opens.

    This behavior seems to be incompatible. The pop-up submenus should open either on click any element of top-level menu (menu bar horizontally) or only on mouse over / roll of the menu bar.

    I want the pop-up submenus to open only when the click on the top-level menu (menu bar horizontally). So I added event handlers for the passage of the mouse as well as the rollOver events (I don't know which event gets actually produced on hovering over the menu bar horizontally). In the case of managers, I called the Event.preventDefault () method to prevent the default behavior (ie the opening of pop-up submenus).  But nothing works. I felt like I have no control over it.

    How to remove the default behavior and open the pop-up submenus only on the click event of the menu bar?

  • How to prevent the automatic upgrade for Windows 10

    Press reports say that Microsoft will 'soon' 10 Windows upgrade recommended for Windows 7, leading to the automatic download and installation.  I don't want that.  I have upgraded to Windows 10, then returned to 7 (leaving an extra 100 GB of something on my hard drive).  I intend to hold out until the last minute, and perhaps later.

    So, how to prevent this scheduled automatic upgrade?  Do I have to turn off updates in Windows 7 and manually review every update?  What I read who cannot help because Microsoft does not offer as much detail about the upgrades as in the past.

    Computers were a hobby for me in 1980.  After 35 years the computers are now a tool and their maintenance is a chore.  I'll learn Windows 10 when I need to and not before.  I really don't want to use 10 at home and at work 7.  When my employer upgraded, so I will.

    Hello DilbertFan,

    For the first year that Windows 10 is out, he will be free to users with a license for Windows 7 or 8.1.

    If you don't know that you do not want to update then please copy the text following that I have which is in italics below and paste it into Notepad.

    The Publisher of the registry Windows Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Gwx]"DisableGwx"=dword:00000001

    Once you have that then go ahead and save it to your desktop and save it under "block 10" or something like that. ""

    Return to your desktop and locate this file and change the extension from .txt to .reg file

    Save it, and then double-click the file. It is to modify the registry to block the upgrade of Windows 10. I use a lot.

    Thank you
