Connecting client and server on a same PC

Hi,
I installed oracle personnal DB 10g on my computer then I installed the client 10g on the same computer,
I would like to know how to configure the files ("HOSTS",...) so I can enter on the client and work on the database. (It well help me simulate the work before having a real server)
I already create a database on the oracle personnal named"ONDA" but I don't know what ip adress use and what to do.
I tried some tutorials but doesn't work

Iam using Oracle 10g client and Oracle 10g R2 on the same computer (windows xp)Separate installations? Not needed, as the db installation includes a full client.
Can you show where I had to write this "$ lsnrctl stat"
and where I had to write this "$ sqlplus user@'hostname:port/servicename'" ?at the command prompt. (the '$' is just shorthand for the command prompt itself. at the prompt, you enter 'lsnrctl status'.)
Whats is my servicename ?ONDA
Can you give me please a quick tutorial ?
http://edstevensdba.wordpress.com/presentations/
I put the adress 127.0.0.1 for both server and client on the file "HOSTS"
I wroteon HOSTS:
127.0.0.1 server
127.0.0.1 client
should just have
127.0.0.1    localhost
xxx.xxx.xxx.xxxx   somehostnamewhere 'xxx.xxx.xxx.xxx' is a fixed ip (servers -- and your database is a server process) need fixed ip addresses
where 'somehostname' is whatever name you want to use to refer to your computer.
then I went to \network\admin\tnsnames.ora and I wrote:
ONDA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 2080)(PORT = 1521))where did you come up with that value for HOST= ?
(CONNECT_DATA =
(SERVICE_NAME = ONDA)
My database (on sever ) is named ONDA
I don't know what to do on the listner? wich listner modify (server or client) ?There is no such thing as a 'client listener'. The listener is, by definition, a server-side process.
DId you read -- and heed -- the installation instructions, especially those concerning installing a loopback adapter and a fixed ip address?

  • Strange problem with SQLPLUS when client and server on the same box

    Hi,
    I have the problem with SQLPLUS when clinet and server on the same machine.
    With client and server on the same machine i am running the command
    sqlplus -l username/password@connect_identifier as SYSDBA.
    With this command, even if you pass in wrong username or wrong password or both as wrong you can able to connect to database and execute queries.
    Once Connect_identifier is correct and trying to log in as SYSDBA ,sqlplus will log in to DB with any username and password.
    How to get rid of this behaviour. Is there any way to do this.
    I am running this command by creating a process in C#

    How does Oracle/SQLPLUS allows any username or password to log in to DB with SYSDBA Privillages? What is the concept behind this.?
    This is explainted in the above mentioned link:
    Operating system authentication takes precedence over password file authentication. If you meet the requirements for operating system authentication, then even if you use a password file, you will be authenticated by operating system authentication.

  • How to show a picture both on client and server at the same time (X11?)

    Hi Guys
    I want show a picture on my client as well as on the server(in another location) at the same time, pretty much like showing something both on laptop and on a projector. Assume I have a picture sssss.jpg on the server A1, if I want to open that picture to my client, I can simply to do the following from client A2:
    xhost A1
    telnet to and login A1
    setenv DISPLAY "ipaddress of A2":0.0
    Anyone can direct me how to show picture the client that I am sitting at an also show on the server at the same time?
    Thanks

    VNC would let you do that. With a shared connection, both machines could run a VNC client to the same session.

  • How to run a datagram socket client and server program

    hi,
    I am new to socket programming. I am following the tutorial of sun for socket programming...The link is
    http://java.sun.com/docs/books/tutorial/networking/datagrams/clientServer.html
    I have understood the concept, but the problem is i cannot run the program. I am using netbeans and i have created a package and stored the files QuoteServer,QuoteServerThread, QuoteClient in this package. How can i make the server program run first and then client program in netbeans
    kindly help me
    Thankyou

    I think you are trying to run both server and client
    on one machine!!!
    It is impossible, your server is blocking the port to
    send packets, so you must run client on another
    computer!!!It's not impossible to run a client and server on the same machine just for testing or as a demo. Just have the server listen on one port and the client use a different port.
    No need to use 2 seperate computers. I've done it one computer before without a problem.

  • How to handle when Client and server write to the socket at the same time

    Hi all,
    I'm writing a socket communication when client and server may write information the the socket at the same time. I look every where but the samples from the internet only shows example of server replies to client after receiving requests from clients.
    Let's say that:
    Client 1 ->Socket 1 -> Server 1
    Now if there are two threads in the server, one blocked waiting for the input from client on socket 1, the second one write something on the socket to client 1, is it possible?
    And if it's possible, if at the time Server 1 writes information to Client 1, Client 1 writes some information to Server 1 too, will there be any conflict problem or the socket could handle that two ways communication simultaneously?
    It's critical questions for me. Thanks for your help.

    I really use Server Client paradigm. However, beside the request, response mechanism, there is also an additional mechanism called update which server periodically send information update to client without the need for a request from client.
    So you suggest client should initiate 2 sockets, one for request and response, one for receiving update from the server? Will this work?

  • Async tcp client and server. How can I determine that the client or the server is no longer available?

    Hello. I would like to write async tcp client and server. I wrote this code but a have a problem, when I call the disconnect method on client or stop method on server. I can't identify that the client or the server is no longer connected.

    Hi,
    Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
    According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
    private async void Process()
    try
    while (true)
    var data = await this.Receive();
    this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
    catch (Exception exception)
    Console.WriteLine(exception.Message);
    Unable to read data from the transport connection: An existing   connection was forcibly closed by the remote host.
    By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

  • Client and Server in one process

    Hi all,
    I am trying to create a process which can act as both Client and Server.
    How can I do this?
    Thanks!

    AH. That's a better definition or explanation. Thanks.
    This smells of a single process with multiple threads, each thread handling the basic needs of your requirements. In other words, have a thread deal with making one or more client type connections (use a main thread - the client controller - to spawn client-connection threads. This assumes you need multiplicity in your client-connection model.
    Then make another thread - the server controller - to handle inbound connections, spawning a new thread for each inbound connection. Your main thread, the one that contains your main method, can watch everything that's going on and log or report what's going on in your client and server threads.
    Going into specifics would be a lot to do here. Maybe someone is up for the challenge. Of course, this being a "New to Java Technology" forum, these concepts may be a bit beyond your skillset.
    This is not the only way to go about solving your problem, but it's the only way I can think of at the moment given your requirements.
    Hope this helps some.

  • Abap proxies ( Client and Server proxies)

    Hi Team
    Good day to you. I am now started doing some example scenarios on ABAP proxies(ie Client and Server proxies). After going through the blogs which are avialable, i am writing this question to you for clarification.
    As per my understanding, the below are the required predefined settings which i need to do in my landscape to generate abap proxies(ie client and server proxies).
    My landscape includes the below systems.
    System A : SAP XI 3.0 system and
    System B : SAP R/3 on WAS 620
    SAP R/3 predefined Steps
    1.Create HTTP connection in the business system.
    2.Configuration Business system as local Integration Engine.
    3. Connection between Business System and System Landscape Directory.
    4. Maintaining the SAP J2EE Connection Parameters for LCRSAPRFC and SAPSLDAPI in SAP J2EE engine
    (Here in the step 4, i found the below needs to be done)
    1. Goto J2EE Engine
    2. Choose Cluster --> Server --> Services. JCo RFC provider
    3. Under RFC destination specify the following:
         Program ID: LCRSAPRFC
         Gateway Host: <Integration Server host>
         Gateway Service: <Integration Server gateway service>
         Number of process: 3
    4. Under Repository specify the following:
    5. Choose Set.
    Application Server: <Integration Server host>
    (i am not able to perform the steps which comes under point 4. so please Guide me how to goto J2EE engine and configure accordingly.
    5.  Maintain SLD access details in Transaction SLDAPICUST.
    As per my understanding, i need to do the above predefined configuration steps in SAP R/3 system (ie bussiness System) for doing Abap Client or Server proxies.
    And in the meantime, i would like to know whether i need to do any predefined configuration steps in XI 3.o system also. Please check and suggest me accordingly.
    Once i get clarification on predefined configuration steps, i will proceed with the example scenarios  on client and server proxies which are already in SDN.
    Thanks in advance.
    Regards
    Raj

    Hello Pavan
    thanks for your response.  you said that for the connection type 'H' we need to provide values for GATEWAY HOST and GATEWAY SERVICE but here i need to create the RFC destination of type 'T'. so please tell me whether i need to give the values for GATEWAY HOST and GATEWAY SERVICE for connection type 'T' also and the second thing is please tell me the difference between Application system and bussiness system accordingly to my landscape which i mentioned in my question.
    I am in little confusion because as per the requirement for abap proxies in the blog they mentioned that all these setting should be done in the bussiness system (ie SAP R/3) but you  are saying that Application system. so please clarify.
    My landscape which i am going to use in Abap proxy generation
    System A: XI 3.0
    System B: R/3
    Here which is bussiness system and which is application system. Pls calrify.
    Thanks in advance.
    Regards

  • Communication between client and server

    I am using sockets for communication between the client and the server. is there any other way that i can use for communication between the client and server???

    Plenty of ways: JMS, SOAP, RMI, a RESTful API, writing-files-to-a-shared-directory-on-the-disk, Sneakernet, ...
    Some of them use sockets (or better TCP/IP) as the underlying protocol.
    But to give you a good answer, you would have to tell us why you want a different way. I hope you're not searching for a different way just for the sake of being different.

  • JSSE  Client and server communication problem .err:untrusted server cert

    Hai all,
    I am trying to communicate JSSE client and server.
    I have created root.cert(CA),root.key,server.cert,server.key , client.cert and client.key. All these certificates are created using openssl.
    I have placed root.cert in default keystore cacerts.
    I have created a keystores(server & client) name mykeystore.
    I have placed root.cert and client.cert in the client keystore.
    I have placed root.cert and server.cert in the server keystore.
    But during the run time i am getting javax.net.ssl.SSLException: untrusted server cert chain.
    please suggest the modifications needs to be done to fix the error.
    please tell me In the client keystore and in the server keystore....what certificates we need to put?
    whether my approach as said above is correct or not?
    In java code how to specify this particular certificate we are referring?
    I have coded in this way ....
    SSLContext ctx;
    KeyManagerFactory kmf;
    KeyStore ks;
    char[] prasad = "prasad".toCharArray();
    ctx = SSLContext.getInstance("SSLv3");
    kmf = KeyManagerFactory.getInstance("SunX509");
    ks = KeyStore.getInstance("jks");
    ks.load(new FileInputStream("mykeystore"), prasad);
    kmf.init(ks, prasad);
    ctx.init(kmf.getKeyManagers(), null, null);
    factory = ctx.getSocketFactory();
    But my doubt is we are specifying only keystore name with that how it will check root.cert(ca) and client.cert and server.cert?
    Is there any modifications need in my code?
    Please tell me some way ...
    Thanks ,
    Prasad.

    Hi prasad,
    There will be a problem with the certificates being received from thr remote server or client. Check that your trust store contains the certificate of the remote machine or the CA that signed it and that the certificate has not expired.
    Also be sure that both machines are using the latest version of the JSSE.
    Hope this will help you.

    TNS-12542: TNS:address already in useThose last two lines tell the tale. Something else is running on port 2525. Why are you trying to use that port for your listener?
    Use netstat to find out what process is using the port.
    And as a follow-up, why configure two listeners?
