TNS Address already in use error

Using Oracle9i, through the ODBC driver on a Windows 2000 machine, we receive the above error (ORA-12542) whenever our application attempts to establish more than 22 concurrent connections. Is there a performance limit or something that's tunable in Oracle9i?

Try creating a registry value under
HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE called USE_SHARED_SOCKET and set it equal to TRUE.

  • Consistently Getting TNS-12542: TNS:address already in use error.

    Hi
    We are facing problem with listener service as It crashes with the error TNS-12542.
    Once we restart the server it gets started again and work for some 3-4 days.
    Than it crashes with the same error.Oracle version is 10g.
    Any idea what could be problem?
    Thanks in advance.

    Thanks for your time and reply Yas...
    Actually, I am trying to stop it and it hangs. Nothing else except help works on the listener prompt but the listener process is running.
    I killed the listener process using kill -9 and now I am not able to start it. I tried different ports also. Can someone please help me solving this? Start to stop commands just hangs.

  • Per-VRF TACACS config gets "Address already in use" error

    I have created a per-VRF TACACS config on a couple of network devices. I can ping the ACS servers through the VRF. TACACS makes the attempt to contact the servers, but the following message shows up in the log when I debug TACACS:
    *Mar 11 08:57:38 starts: TAC+: Opening TCP/IP to x.x.x.x/49 timeout=5
    *Mar 11 08:57:38 starts: TAC+: TCP/IP open to x.x.x.x/49 failed -- Address already in use
    I can't find anything on CCO that references the "Address already in use" message.
    Has anyone run into this?

    Hmmm...no, the server group is still there. Did you see the other post which describes the bug ID? The link to the bug is:

    Do you get the IP address is in use log message?

  • "BindException: Address already in use" error all the time!

    I made a simple program that streams lines of text across the network/internet and a simple client program to display that text. The problem is, regardless of what port I choose, I always get this exception on the server's side:
    C:\Users\Nathan\Desktop>java LyricalUploader

            at LyricalUploader.main(LyricalUploader.java:11)What bothers me is it creates the ServerSocket just fine (that's what the output saying "Bound" means) and if I replace the new LyricalThread(ss.accept()).start(); line in the code below with new LyricalThread(ss.accept()).run();, it works fine, It just can't handle more than one client. I have tried many many ports and they all have the same result. What am I doing wrong?
    Here is the code:
    import java.net.*;
    import java.io.*;
    import javax.swing.JFileChooser;
    public class LyricalUploader{
    public static void main(String args[]){
      ServerSocket ss = null;

      try{
        while(true){
          System.out.println("Started Listening");
          ss = new ServerSocket(49625);

    Hi,
    your Server must create only one ServerSocket, not multiples! So write
      try{
        ss = new ServerSocket(49625);
        System.out.println("Bound");
        while(true){
          System.out.println("Started Listening");
          new LyricalThread(ss.accept()).start();
      catch(Exception e){
        e.printStackTrace();
        System.exit(1);
      }and take the creation of the ServerSocket outside the while-loop.

  • Error: - ORA-12542: TNS:address already in use. How to resolve?

    Hello all,
    Can anyone guide me how to resolve this error. I have encountered this error for the first time!
    Usually I run my batch job at every night. It generally takes 2 hours to 3 hours to complete. Till date I have not faced any problem of this kind.
    I understand that there is conflict of Ports. The port that is being used by my listener, is also being shared by some other. I am not aware of that other program which may be using the port assigned to the listener.
    Thanks in advance.

    Hi,
    I had the same problem today morning in my production. Listener was hanged and receved OEM alert as "Listerner Down" when i go and start the listerner its was failed then i found multiple PID created the same listerner then i went i killed both of the process and started the listener successfully.
    Could you please tell me what was the exact cause.

  • Remote debugging issue: Address already in use

    First, I want to explain that to use remote debugging in oracle UCM server (IdcServerNT.exe), I add these lines at */server/bin/intradoc.cfg*:
    JAVA_OPTIONS_debug_enable=-Xdebug
    JAVA_OPTIONS_debug_options=-Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n
    and since the JAVA_OPTIONS is shared between admin server (IdcAdminNT.exe) and non-admin server (IdcServerNT.exe), to prevent "Address already in use" error, I added same lines but with empty value into */server/admin/bin/intradoc.cfg*:
    JAVA_OPTIONS_debug_enable=
    JAVA_OPTIONS_debug_options=
    or alternatively enable it but use different port for the "address=xxx".
    Now the issue is when I had run the non-admin UCM server with remote debugging enabled, then I tried to run the Component Wizard, I got "Address already in use" error:
    ERROR: transport error 202: bind failed: Address already in use ["transport.c",L41]
    I found out that's possible because Component Wizard (ComponentWizard.exe) is using same setting file with non-admin server (IdcServerNT.exe): */server/bin/intradoc.cfg*. It's obvious that happened because of ComponentWizard.exe is in same location with IdcServerNT.exe, so I think other tools like Batch Loader and System Properties will be affected with same issue too.
    Because of this issue, everytime I want to open Component Wizard, I had to stop the non-admin server which is inconvenient.
    So, the question is there a way to define separately or disable the JAVA_OPTIONS_debug_enable & JAVA_OPTIONS_debug_options for Component Wizard?

  • Error starting ORMI-Server.  Unable to bind socket: Address already in use:

    hi,
    I run the folowing command "start_oc4j.bat" to start Oc4j.
    It starts successfully.
    Then I start "BPEL PM Server".
    I get the following error,
    "Error starting ORMI-Server. Unable to bind socket: Address already in use: JVM_Bind".
    I understand the above errror because both of them are trying to bind to the same port. And both of them are trying to start ORMI server. Can some one suggest how to get rid of this problem.
    I tried giving different port numbers for them, but that did not work. Let me know, how to over come this problem.
    with regards
    shaila

    You may have another OC4J running on your computer.
    You should change the port number in the file config/rmi.xml.

  • Address already in use: JVM_Bind error in DOS

    Hello,
    I am writing a multi threaded client server (Both client and server are multi threaded) program.where I have set of clients performing secure file transfer amongst them self. Here there is a Indexing server who is keeping record of all the files contained by clients. A client will make a request for a file to the Indexing Server which intern return the port no. and address of the client having that file. Now this client will connect to another client (Which now will act as server) to get the file and public key .
    Now I am connecting to server by using fix port number.
    Socket client = new Socket("127.0.0.1",2345)
    Also since the request for file from another client can come therefor I am creating a thread to start listning port on client side by,
    serverSocket serversocket = new serverSocket(client.getLocalport);
    //provided that connection to server with port 2345 already made.
    but when I am running this program through "DOS" it is giving me an error Address already in use: JVM_Bind.
    //checked through netstat and found that localport for the client is bound to 2345 (That is obvious)
    But when I am running this program in unix I am getting no error.

    ServerSocket.setReuseAddress(true) does not work on vista. Why? The following code is OK on XP, but throw the above exception on vista.

  • Socket Error: Address already in use

    Hello all,
    I'm trying to get the Trac bug tracking system installed on my system(running snow leopard). After quite a bit of tinkering I've managed to install Trac, but as of now, its a standalone entity. I am trying to get this linked to the apache webserver, but having no success. Has anybody done this before? I haven't used unix to this level before and so am struggling with that as well... any info on this is much appreciated.
    One of the instructions to test run Trac as a standalone component was using this command tracd --port 8000 /path/to/myfolder (according to installation instructions at http://trac.edgewall.org/wiki/TracInstall). I stopped it using Ctrl-Z and now when I try to run it again, get the following message and error:

    I realize that closing the terminal window "frees" the socket. But, is there something else that I can do while stopping the running application to ensure that the socket also gets "freed"?

    Control-Z does "stop" the process, but it doesn't kill it. Use Control-C to do that. Then, you may have to wait a couple of minutes for the OS to free up your socket until you can try again.

  • Ftp (GNU inetutils) 1.6 error : [ftp: bind: Address already in use]

    hi,
    recently I discovered that I cant connect to many ftp servers using the common command line ftp client from a 64bit archlinux box.
    I tried connecting from other PCs at the same network (iMac) and it works without problems, the error is general, shows with every ftp server I tried,
    the client connects and then freezes or returns an error (depending on the ftp server)

    I got no firewall or iptables rules, I installed ncftp with pacman and it works, so I assume it's a ftp (GNU) client error,
