I have here a way to force the client to use a virtual IP address?

If a client makes a connection between a server where multiple IP addresses are active - is there a way to influence that one is chosen for outgoing traffic?
Background:
The application is moved as well as its virtual IP address.
After reinstalling the "sender address" should be the same for the tcp.invited_nodes-based IP filtering.

Thanks in advance!

Nope. Don't remember seeing such an option. Server side, this feature is of course available to bind endpoints tcp specific IPS.

Why exactly do you need this function on the client side? I don't understand the "+ the client connects using the IP addresses changing, even if the application is to have a virtual IP unique and constant. "This requires a source more open on the FW between DB and the customer as necessary +" problem you stated.

If the client opens 2 connections to the base, then it will be 2 connections through the firewall. As the private client port will be different for each connection and make the unique connection.

Now if these 2 client connection use IP1 and IP2 on the client for the connection, won't matter - as 2 separate connections will be created independently.

If for some reason you want to from the db server or firewall see these client connections entering as minimum IP sources - then you can do this by using a unique IP address for all incoming connections by NAT'ing.

You ask a NAT firewall (using iptables for example) and simply rewrite incoming IP headers for tcp on 1521 packets the IP NAT and transfer the package on the firewall/db server.

This server will see a unique client IP only for all inbound traffic. Works pretty well for Oracle that the client connection string includes the hostname of the client/hostid - so you can always in Oracle see what session is from a client who, despite all these sessions with the same source IP address.

  • How to force the client to connect to the specific access point?

    I have a client that connects to an Access Point to the upper floor.  The connection is "Very low" and pings are restless.  Is there a way to force the client to connect to the point of access on its own soil in the hallway.

    Thank you

    There is not a way to force the client to use a specific side access point controller of things.  According to the specifications, the client decides when and where to associate.  You can try to disable some of the rates below data or lower power tx of the AP to reduce the coverage of each access point cell.  By doing this, the client cannot see the other as favourable AP.

  • Any way to force the execution of the workflow on existing data?

    I wrote a workflow rule to update the field back to match the sum of a few custom customer field. When the record is updated or a new record is created income is updated with the desired value. However, I have a few thousands opportunities that already exist. Is there a way to force the workflow to run on any existing data? If not, is the only option for export and re - import all data used?

    Using the mass update is another choice, but to 50 cases per race that is rather painful. The route of export/import is much less clicks. Just empty the opportunity name and filed a trivial you don't use. Change the trivial field in Excel. Recharge with update.

  • Is in any way to 'force' the NB of 550 to 1024 x 768 resolution

    Hello

    Is any way to 'force' the resolution on the NB of 550 to 1024 x 768, Winbdows 8 can take place on this issue? There are some hacks around other netbooks, but I couldn't find anything for the netbook from Toshiba.

    Hello

    In my opinion this is not possible because the internal LCD display supports a maximum resolution of 1024 x 600

  • I put 240 photos in an InDesign document using mini bridge.  Is there a way to hide the photos I used after I have put in my document?

    I put 240 photos in an InDesign document using mini bridge.  Is there a way to hide the photos I used after I have put in my document?

    I think Willi, and I even read your question differently. I thought you wanted to hide the images in Mini Bridge once they have been placed in InDesign so that you could keep track of those who you have (if you put twice the same image). If you want to hide in InDesign (as Willi read the question), his suggestion is very good. Another alternative is to use the shortcut to hide (command 3 on Mac OS), after putting the images, but before you click next to deselect them.

    I do not use Mini Bridge, so I can't help you there. If you want to use the full version of the bridge, you can use a Move command to move the selected items to another folder (temp), where they will not appear in your current folder. You can move after that that they all were placed. A bit of a hack, but it could work.

  • Force the VM to use the wired ethernet port instead of wireless

    Hello

    I use ver 9 workstation.  I have my host computer (win 7 64 bit) connected to our network of offices using the connection with wireless computers.

    I use a windows xp based virtual machine image that connects to devices of 3rd party via the ethernet port wired in Bridge mode.

    Is there a way to force the workstation on the use of only the cable connection and don't EVER try to connect via the wireless?

    At the moment I have to disable the wireless for the workstation to access cable port, if the without wire is activated, so you may not see anything on the wired port...

    It also causes headaches with ip address conflicts (3rd devices use the same IP range as our network of offices) if I don't have the VM running and wireless power.

    Any help or advice would be appreciated

    Tim

    Use the virtual network Editor to bind to the target adapter for VMnet0 and set the NIC of the virtual machine to use connected by a bridge.

  • Satellite C55 - how to force the games to use gforce GPU?

    Hello

    It seems that I have 2 graphics cards on my Satellite C55: a 4000 Intel and a gforce 740 m. I tried to force the games to use the gforce on Panel nvidia configuration, but in the games settings (for example in the Hardware tab of flight simulator 2004), shows only the Intel.

    No idea how to resolve this?

    Thank you

    > it seems that I have 2 graphics cards on my Satellite C55: a 4000 Intel and a gforce 740 m.

    The Intel GPU is part of the Intel
    The nVidia GeForce is the external graphics card and it can be used for the application of strong performance as games

    Check these youtube videos how to do this:
    https://www.YouTube.com/watch?v=WVBEPhE_Osg
    https://www.YouTube.com/watch?v=Zh4HCadTY_A

    You can assign any application to use the dedicated made Intel or nVidia GPU card.
    This can be done in the nvidia Control Panel.

    1. click on start and then Control Panel. Select Classic view in the left side of the window.
    2. double-click on the NVIDIA Control Panel.
    3. click view, and then add the "Run with graphic processor" Option to the context Menu. Close the NVIDIA Control Panel.
    4. right click on the title of the application and select run with GPU. Then, click on NVIDIA processor high performance.

  • Is there a way to force the list of databases Access, rather than having the giant icons in my taskbar?

    When I have a few databases open, my taskbar has an icon for each file that is opened in a sloppy "battery."  Naturally, when I hover over the battery, miniature windows display each file.  After that I have a good number of them open (for example, around 10, 11 or 12), stacked icons convert a vertical list.  Is there a way to force this vertical list, even with also open some two or more db?

    If you have Windows 7 Pro or Ultimate, you can use Group Policy.  Otherwise, you will need to perform a small registry change.

    For Pro or Ultimate, see method 1 here--> http://helpdeskgeek.com/windows-7/disable-taskbar-thumbnail-previews-windows-7/

  • Y at - it no way to force the breeze line in the body of the text SystemDialog...

    According to the title

    No way to force line breaks in the text SystemDialog?

    I've tried \n in the text + the \n gets simply displayed.

    Which seem to be able to put break tags in the text - the destroyer of momnetics language file resources do not like tags.

    Thanks for the tip!

    What seems to happen is

    (i) If you pass the setBody() method a string literal - as in setBody ("line1 line2 \n"), everything's fine

    (II) from prev poster, if you set the text via a QML the \n file is processed properly (not verified, but think prev poster)

    HOWEVER

    If you load the text of a TS file, as in setBody (QApplication::translate ("", "string reference")); and the string in the TS file contains characters \n - the new line does not - the '-' and ' no characters are displayed instead. This is despite the procecssing of TS files

    To have line breaks in TS file using the
    coding (instead of the \n)

    Note. The TS file mangler will pronounce mangle your file TS containing the
    and replace with the new actual line in the xml text - then perhaps that is replacing soln - in other words a new line in your text. But relying on somewhat dubious text file formatting xml seems unreasonable...

    We opted for an approach of argNum % and used a QString.arg)

    For example

    LineOne % 1LineTwo

    and used a String str = tsFileString.arg (QString ("\n"));

    as we already use the QString.arg () on this particular string even when.

  • Is there a way to force the href = "mailto: to use the default email client"

    I would use the href = "" mailto: "in my site Web automatically opens an email but the end user receives the message"there is no associated messaging program to perform the action requested... " »

    Is there a way to force to the mailto to use the, and the user's default e-mail client?

    Thank you for your help

    Hi James -.

    This is the default behavior of browsers when you handle the mailto link.

    Please keep in mind almost half of Web site visitors do not have an email client because they use mobile devices or computers in public or web-based email like Gmail, messaging, MSN etc.

    Please do not feed the spammers robots. Recommended is to use a HTML element 'form' in conjunction with a script of processing forms aside server. Ask your webhost if they provide one for you.

  • No way to force the SMB2 instead of SMB3

    Running Server 5.0.13 on a Mac Mini to 2015 10.11.3

    I have a very strange problem running a particular software on client computers. The software cannot write to a particular file type (the. INI files necessary for the operation of the program), but only when he tries to write the file to the file of OS X Server (which connects via SMB 3.0). It can write the file locally and on an old Windows Server (which connects via SMB2.1) and the program can write other files on the OS X file server - just not the. INI

    Permissions do not appear to be the problem, because they are currently open. I think at this point, it must be something weird with SMB 3.0, or opportunistic locking. Any advice on force the connection to SMB2, either change the opportunistic locking would be appreciated.

    OS X uses now the implementation of SMBx own SMB Apple, rather than the more common implementation of SAMBA, so methods and SMB on a Mac configuration options are now different and much more limited.

    If it's a Mac user with a connection to an SMB server problem, so the file in question would be ~/Library/Preferences/nsmb.conf which is in the individual user preferences folder. This file does not exist in the standard sense, the default settings are used, if this file is created with valid parameters, and then it replaces the default settings.

    For a Mac operates as a SMB server, however it is less clear what are the options, there is a file preferably to Library/Preferences/SystemConfiguration/com.apple.smb.server.plist, but Apple tell you do not change this file because it is kept is updated by the software to Apple for example Server.app. This means that if change you it then probably any change would be quickly replaced again by own Apple software.

    The other option remaining is /etc/nsmb.conf that this file also however does not exist in standard. Once again if you create it will substitute the substitution of parameters by default and identical options in a clean users ~/Library/Preferences/nsmb.conf

    I suggest doing the following in Terminal.app to read the documentation from Apple on this topic.

    NSMB.conf man

    smbd man

    My best guess would be the creation of /etc/nsmb.conf on your Mac server with an option to define smb2_only may be the best approach. What isn't clear, is find out if this applies only to the use of a Mac as a customer or if it will also apply to be a server.

  • Is there a way to force the transfer of files in a certain order?

    Hello
    XP sp3 running on computer dell laptop 6400.

    I'm trying to transfer an audiobook on an sd card and the need to keep the files in order. Periodically, one or two files are sent out of sequence. Since my Player reads the files in the order they were sent, this is unacceptable. Is there anything that I can force the orders files are sent?

    Thank you

    * original title - scrambled records *.

    The device creates a "playlist" because the files are copied, and so that they are copied.

    If the files are all in alphabetical or numerical order copy the files from the CD to the hard drive, then copy them to the hard drive of the machine with the copy command and a list of files at the command prompt.

    For example, to copy all audio files to a folder named book on the C: drive, and then from the command prompt try:

    for /f "tokens = *" %a in ('dir /b c:\book") copy 'c:\book\%a' x:\

    (where x: is the letter from SD card)

  • How can I have 2 email accounts open at the same time using the apple mail icon?

    How to open 2 e-mail accounts at the same time?

    Hello carroll12,

    Thank you for using communities of Apple Support.

    I see that you do not want to open two e-mail accounts at the same time using the Mail application. I understand perfectly. I have multiple e-mail accounts set up in my Mail application. I'm happy to help you with this.

    You can have more than one e-mail account set up in the Mail application. The first time you open Mail, it may prompt you to add an e-mail account (if you have not already done). Select an account type, and then enter your account information. To add another account, choose Mail > add an account, select an account type, and then enter your account information. Make sure that the Mail check box is selected for the account.

    If you have already both set in place, and I just want to be able to view both on the screen at the same time, open Mail, and then click file at the top.  From there, select the option for the new window of the observer.  This will open a new window where you can see each of the individual mailboxes on the same screen.
