Prevents the sessions to connect to the DB

DB Version: 10 gr 2, 11g

If you do not want the sessions to the DB; Let's say, for a maintenance window. What do guys do?

You guys down the listener? Or y at - he recommended otherwise?

Stop the listener won't help because it will disable only new connections but will have no impact on the existing database sessions. I recommend that you restart the instance of database in restricted mode http://download.oracle.com/docs/cd/E11882_01/server.112/e17120/start002.htm#ADMIN11155.

  • Prevent the owner of the schema using development tools

    Hello world

    We are doing some tasks to meet the PCI DSS requirements. One of them is preventing the schema owner to log in using development tools (TOAD, sqlplus, plsqldev, SQL Developer...). I found a solution here:

    http://kamranagayev.com/2009/10/04/block-developers-from-using-Toad-and-other-tools-on-production-databases/

    But as comment said, if we change the name of the .exe file, we can easily connect. I thought to do info = module, no program info. I tried with no success. I read somewhere that in after logon, the client info trigger is not set completely. So that we can't get info module exactly after logon trigger (I tried and I have seen this module was same as program interviewed since the session$ v).

    Another comment suggested that we allow some programs to connect instead of refuse many unauthorized tools. I think it is a good idea. But I wonder if some guys know rename tool dev as our authorized tools and it can connect.

    If anyone has any ideas or solutions, please help me. Thank you.

    One solution is to use two schemas - detail a. has no privs assigned to it (not even CREATE SESSION), but contains all of the objects (tables, indexes, views, code, etc.). Diagram B does not all objects, but given privileges to operate on the objects belongs to priv a. withdrawal CREATE SESSION from scheme a scheme b (in for example Prod) will achieve your requirement.

    I was installing updates of windows and the computer is dead in the middle of it.  When I turned it back on it brought me to a blue screen with error codes: 0x0000007B (0x80399BB0 0 x 0000034 0x00000000 0x00000000).  It prompted me to do a system restore or to get to the system recovery, however it shows that there is no available restore points (even though I know that there are a bunch of them... because I checked this before I tried to make the updates of windows).  I went into the system recovery & the scan of my system with a scan of the additional memory, and there is nothing wrong with my real hardware.  The error recovery of the system that was given to me after the scan of my system is "a fix prevents the system to start.".  I looked at different positions in line with methods to get around this, but none of them does not seem to work.  Vssadmin does not appear on my system to try to use it again.

    I'm almost done try all this and ready to make a fresh Windows... Install but I hate to really do this knowing that everything was working fine before all this & my hardware is fine... If I could just figure out how to get rid of this darn update all this hangs then all would be well.  Anyone have any suggestions?

    Hello

    When a computer dies in the middle of an update, it often corrupts many system files leaving no other choice than to reinstall. This is why it is always recommended that laptops/notebooks be connected when you install updates. If Windows was trying to replace a critical system file when the power is off, there are very little that you can do to fix it. If possible, start with a system for the Recovery Console disk and try running "sfc/scannow" to correct or replacement of the damaged system files, but does not satisfy, you are faced with a relocation.

  • WSD Print device driver error prevents the standby machine

    Hi all.  I've been struggling with this problem for a few months, without success.  On my system: Dell PC, Vista 32, SP2, using a Brother MFC 490 all-in-one that is connected to my wireless network.

    My problem is the following: a few months ago I noticed that the Bureau has refused to go to sleep, instead showing a popup that says, "the device driver for the WSD print device prevents the standby machine."  It's embarrassing at the very least, a waste of money and the system of life at worst.

    I tried the following without success: restored the system to a point before the show, updated the wsd, uninstalled/reinstalled the wsd driver driver & peripheral, uninstalled the Brother software (the printer has remained on the system, thanks to the auto detection) and banged my head with great enthusiasm on the keyboard.

    If all goes well, there is a relatively easy fix!  Thanks for your suggestions...

    Hello DFontanella,

    The error message indicates that there is a problem with the driver and preventing the computer to go to sleep.

    I suggest you uninstall the drivers for the device. Disconnect the connected device and try to load the generic drivers of the printer in the back.

    Also try to restore the driver from Device Manager:

    To roll back a driver in Windows send the driver to the version that was finally installed for the device. Restoring a driver is an easy way to return a driver for a working version when a driver update fails to fix a problem or maybe even a new problem.

    1. open Device Manager. To do this, click Start, type device in the area Manager search and then click on Device Manager in the list programs.

    2 right-click the device for which the previous version of the driver is desired and then click Properties.

    3. click on the tab drivers.

    4. click on Roll Back Driver.

  • Prevent the closing LoginDialog when entering a wrong password

    How can I prevent the LoginDialog from closing when the user enters a bad password? I tried event.stopImmediatePropogation and event.stopPropogation ()... When the user clicks on the button "Login" dialog closes connection when I want to stay open and display its errorText = "Incorrect password"

    private function login(password:String):void{
        var alert:LoginDialog = new LoginDialog();
        alert.title = "Login";
        alert.message = "Please enter your Password:";
        alert.passwordPrompt = "password";
        alert.addButton( 'Quit' );
        alert.addButton( 'Login' );
        alert.addEventListener(Event.SELECT, alertButtonClicked);
        alert.show(); 
    
        function alertButtonClicked( event : Event ) : void
        {
            switch (event.target.getItemAt(event.target.selectedIndex).label){
    
                case "Login":
                    if (alert.password == password){
                        continueAfterLogin()
                    }else{
                        alert.errorText = "Incorrect Password!"
                        // i tried both of these
                        event.stopImmediatePropagation();
                        event.stopPropagation();
                    }
                    break;
                case "Quit":
                    stage.nativeWindow.close();
                    break;
    
            }
    
        }
    }
    

    The only thing that seems to work: callLater (alert.show);

       case "Login":
        if (alert.password == password){
            continueAfterLogin()
        }else{
            alert.errorText = "Incorrect Password!"
            callLater(alert.show);
        }
        break;
    

    Easy:

    alert.cancelRequired = true;

    This will keep the dialog box when you press a button and you will have to remove it when needed on the button event handler with:

    Alert.Cancel ();

  • Prevent the loading application if the user is in offline mode

    Hello

    I was wondering if there was a way to prevent the user to access a web application wrapped in webworks if they start the application without a data connection.

    I added event listeners to the window if a user is in the application and goes offline / comes online.

    I would stop at the splash screen and displays an informational message.

    I don't have the time in my current project to perform offline caching etc then hoped for this as a miracle despite that hinder the UX.

    BB10 on a Z10 with webworks last SDK is also used.

    I tried to use the navigator object, but it doesn't seem to detect on first loading of the application.

    Also it does not switch the value when going offline online in the app itself so just left the detection online/offline for event listeners for the moment until I had time to find a better solution.
