Connect the restricted session

Hello

I am aware that from 10 g users (even with sysdba or session limited privs) cannot connect to an instance in session restricted by the listener.
I have an instance of database where I CAN connect to an instance in session restricted (when he is tried with a user with restricted session privilege) via earpiece. All but one single service of the lsnrctl status is RESTRICTED view.

I do not have UR = in my tnsnames file.

I do not use the name of listener LISTENER default port 1521. Name of the listener is LISTENER_HOST1. This could be the reason for this extra service? If so, how to stop this kind of connection via the listening port?

Service with status UNKNOWN results to have a static SID_LIST in the listener.ora - and it will probably be the entry that allows the connection.

This shutdown behavior should be as simple as to remove the database from the SID_LIST, or remove the entire SID_LIST section, listener.ora and restart the listener so that only the registered services are dynamically available.

  • the connection of the given session was lost

    I have connected to the power supply IDRC DSP - 300-2, 5 HR via ethernet by VISA. After the connection system is normal. I send commands and receive responses. But when I stop and start feeding it new VISA refreshes the information on this subject. Get a power supply IP by DHCP, same IP has not changed, but I get the message "VISA: (Hex 0xBFFF00A6) the connection of the given session was lost" when trying to write the function VISA Write command. Information about resources in the visa system I get VISA resource find vi. How to solve this problem?

    PS Power supply connected on the second Ethernet card in the system.

    Yes, what you describe is expected behavior. When you turn off the power, the connection is broken and must be restored. How many times do you need to.communicate with this device? It might be more efficient to open a connection, do what you must do and then close the connection.

  • my wireless connection says "restricted access" no network connection. I used the same key code to get my other computer online

    my wireless connection says "restricted access" no network connection, I used the same key code to get my other computer I can have up to 5 computers online at the same time online.

    Ideas:

    • You have problems with programs
    • Error messages
    • Recent changes to your computer
    • What you have already tried to solve the problem

    Hello

    This means that the computer cannot connect to the router.

    Try this process.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    Above everything is OK, you must be able to connect to the router.  A window that says connected does not mean that you are really connected. Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see. If it is not connected in the log to router from any computer that can connect to the router wirelessly with a wire, disable wireless security, (make sure that the wireless SSID broadcast) is on and try to connect with no. wireless security.

    --------------------------------------------------

    I really checked and configured every thing and it doesn't work.

    Software firewall application that is not configured to allow local traffic (between the computer and the router is also a possible problem.
    some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible, configure the firewall correctly or completely uninstall to allow a clean flow of local network traffic. If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

Then the server itself starts the RDP session to the virtual desktop VM (see Agent).

    The goal here is to lighten the load of the server, without losing the 'automated pool' features and benefits...

  • After you type the master password in session can force type master password once again without ending the current session and start new session?

    Sometimes after using the password to access an account during a given session of firefox, I want to "repeal" this ability of automatic access (i.e. require type the password again once) without having to put an end to the current session and restart firefox.

    It's nice to only have to type the password once per session, there are times when after launching an action that I would let the browser unattended for a short period but to prevent others to access sensitive information on other sites if they can't my master password. Note that this is not the same thing as "locking the browser. Currently, the only way I know to force it is to kill the session and restart the browser but it's not very satisfying if I really want to stay connected (allowed) to a particular site. I hope that adding a button in the Security tab "requires the master password for the current session" would be a simple solution to implement? Thank you for your attention.

    You can connect from the software security device (e.g. click Cancel in the dialog box display the passwords) to force them to return to the MP once more.

  • NOR-IMAQ: The transmitted session or the interface is not valid, why?

    Hello:

    I am facing an error that I can't explain. I configured a NI 1742 smart camera, to do some tests. The camera is configured in Max Max I can make some shots of the image and image captures without problem, I can do the same thing in the Vision Assistant. However, in LabVIEW I can't even start a session IMAQ.

    When I try to log in with the Vi Init IMAQ, I always get an error that says "NI-IMAQ: the transmitted session or the interface is not valid. I don't understand why this is happening. I did some research and found that this error indicates when the specified interface does not exist or the unit is unplugged. But I checked and rechecked, and as you can see in the previous image, the interface exists, and of course the smart camera is connected and working. No error status displays the status doesn't lead. I tried with the VI generated with the Vision Assistant, but had no luck, in LabVIEW always manifest error.

    I have LabVIEW 8.6, Vision Assistant 8.6, OR-IMAQ 4.3, MAX 4.6.1

    No idea why this error?, I tried, but I can't understand why!

    I really appreciate help. I'm a bit desperate.

    Thanks in advance.

    Robst.

    Hello

    Just to make sure, you run LabVIEW RT? and if you are, you are your VI running on my computer or have you create a project and added to your target of the smart camera and the VI under this goal?

    If you use your VI on your local computer, the error message makes sense because there is no img0 interface in your computer.

  • User logged on the server over the RDP session - Small Business Server 2011 x 64

    We have a Small Business Server 2011 standard x 64.  We have the configuration of the remote desktop on port forwarding in the firewall to allow a user to connect to this server using RDP remote desktop.  This isn't a server terminal server.  No, there are no available Remote Desktop Manager settings.

    When the user connects through the RDP application and connects to the server.  If the users session is idle for 15 minutes, the user is connected to the server (not disconnected the RDP session, just to connect to the server).  The user must log into the server every time that happens.  We tried adjusting the Remote Desktop Session Host settings and changed the Session time limits, but this isn't the parameter we are looking for.  We have looked extensively through the default domain group policy and see nothing active to this behavior.  We examined local group policies and studied the session time limits in the user and computer configuration > policies > models Admin > RDP >... session host and it is has anything configured here which could trigger this behavior.

    Yet once, it connects the disabled user, not closing the remote session.  We have also examined the user account for this user and looked for resume posting require logon settings (although with SBS, it is not even there to adjust the display settings).  I had partner Microsoft supports focus on this during one hour (he didn't use too much of my time to support) and they have been unable to resolve within an hour.

Now, I want to add code to B, so that it can be controlled by the DO of A (so that B can be synchronized with A). I can connect the DI of B and B by the connection of the material, but is it possible that I do it just by the software? I want to generate the files to run for both A and B, so I don't want to add to another program. Any suggestion? Thank you.

    Bo,

    You can use queues to transfer data between several screws... with a restriction:

    The screw cannot be part of two different applications (exe).

    So if you plan to distribute your work, you must make sure that both screws are compiled in the same application; If so, use the queues.

    Please note that this is also true if you use user to transfer events.

    Another possibility is to use the detection of changes in your DI (depending on equipment)...

    hope this helps,

  • RDP can connect to a session of console rather than on a Windows XP machine?

    Hello

    I have a Windows Server2003 running of the machine.  I have 3 'stations' running Windows XP SP3, which function as machines of execution to the work initiated by the application on the server. In essence, a repository server where all the jobs are stored and 3 execution servers that run the work at their time. The application (automate BPA Server 8 network Automation) should use the console session (ID 0) to manage the execution of the work.  We would like to use RDP to access servers running, but RDP automatically connects to the console session 0. Is there a way to force the RDP to connect to the console on a Windows XP machine not session?

    Thank you very much for any advice or direction, only you can give me!

    I think that you would probably get a better answer to this question in one of the TechNet forums where they support servers, as I do not have Windows Server 2003 in the House (and probably neither do any of the other people here ), you'll want to check with the server people who have more experience in this sort of thing.
