Java client socket readers

          I'm running a cluster of 3 WL 6.0 servers and when I do a JNDI lookup to run methods
          on a remote interface stub on the client side it gives me the following:
          <Apr 26, 2001 2:16:34 PM MST> <Warning> <JavaSocketMuxer> <There are: '3' active
          sockets, but the maximum number of socket readers allowed by theconfiguration
          i
          s: '2', you may want alter your configuration.>
          I re-ran my client with the two following properties:
          -Dweblogic.system.executeThreadCount=5
          -Dweblogic.system.percentSocketReaders=60
          it still gives me the exception. How do I get this to work properly so I have
          as many socket readers as servers?
          Thanks in advance.
          

Thanks,
          I had understood this wrong, I was configuring on the server, not the client
          application,
          it's all working well now.
          Cheers

  • Increasing Weblogic client Socket Readers etc

    How can you increase the number of socket readers on a client
    application which
    uses JMS, EJB and talks to multiple WLAS servers.
    I get the following message
    Muxer> <There are: '3' active sockets, but the maximum number of socket
    readers allowed by theconfiguration is: '2', you may want alter your
    configuration.>
    But I cant find out how to increase the socket readers or better yet can
    I use the native IO for Solaris and NT clients??

    Hi,
    You can control the number of threads and the precent of socket readers
    through the properties: weblogic.ThreadPoolSize and
    weblogic.ThreadPoolPercentSocketReaders. You would have to pass them to the
    jvm machine at startup for example:
    -Dweblogic.ThreadPoolSize=10 -Dweblogic.ThreadPoolPercentSocketReaders=50

  • Error in the Socket Communication between Java Client and VC++ Server

    In my application, using Java Client to do socket bi-communication with VC++ Server, which is done by somebody else.
    The error is after the application properly running one or two days, the VC++ Server cannot receive the messages passed by java Client, but at Java client, everything is the same, although using CheckError() after every print(), there is no exception thrown.
    The JVM is jdk1.3.1, platform is Win2k Server.
    The outputstream is PrintWriter().
    Please help me to settle down this problem. Thanks in advance.

    I read some thread in the forum, and found somebody had the similar problem with me. Just want to know how to settle this problem.
    In the client/server program. Client is a JAVA program and Server a
    VC++ program. The connection works, and the problem appears after some time. The Client sends a lots of requests to Serverm, the server seems receive nothing. But at the same time, the server is able to send messages to Client. The Client also can get the messages and handle them. Don't understand why there this problem and why it appears when it wants.
    The client is a Win2k platorm with JDK1.3.1 and the server is also a Win2K platform with VC++ 6.0.
    In the Client, using:
    inputFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    outputToServer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
    Hope can get your help.

    java -Dweblogic.ThreadPoolSize=15 -Dweblogic.ThreadPoolPercentSocketReaders= 75

  • Java Chat (Server, Client Socket Connection)

    Assignment:
    The assignment is to deliver two source codes that can run a Server (1) and Clients (2) in order to create a simpel chat program. The server has to wait and check an IP (localhost) + Port, and the client has to connect to that port and create a socket connection. The only thing that should be done is create a new socket connection for each client... and when a client sends a message, the message should be delivered to all clients connected to the server.
    Problem...
    However I can read an edit Java, it's difficult for me to write it. I allready found many turturials about socket connections on the internet, and tried to edit those, but they don't really do what I want unless I really write new shit. Is there a way you guys can help me with this, or that you find a really good website that fits my question?

    According to me ,
    take string variable 'str'
    Take some class ,I think u already taken.....
    Scoket scoket = new Socket(IP,port);
    OutputStream out;
    IInputStream in;
    in = socket.getInputStream();
    out = socket.getOutputStream();
    If sends the msg then use
    out.writeObject(str);
    This line sends data to the other user
    msg resivce from client then use
    str = in.readInput();
    & this str set to the any objects out put .
    Such as TextField.setText(str);

  • Socket Communication between java client and c++ server

    HI,
    In my project,I want to do the following:
    1.Sending datas from client to server.
    2.Getting the response from server to client.
    I written the client in java.but the server is in c++.
    Is it possible to communicate with the server using java codings itself?
    Im able to send the data from my java client to the server.
    but unable to get back the datas from server to client.
    Can anyone tell me how to do this?
    thanks a lot

    hi
    thanks for ur reply.
    I didnt get any error msg while getting the back the datas.
    Actually i divided my application into two parts.
    My application will act as both server and client.
    server ll get the browser request and send to the client and the client will send that data to the c++ server.
    Im able to do that.and unable to get the data from server.
    Didnt get any error.
    can u tell me how to make an application to act as both client and server.
    I think im wrong in that part.
    thanks a lot

  • Socket Readers

    Currently using WebLogic 6.1 SP2 on Win NT 4.0 with jdk 1.3.1. 2 servers in a cluster.
    The following message is seen.
    <ExecuteThread: '10' for queue: 'default'> <> <> <000000> <There are: '7' active
    sockets, but the maximum number of socket readers allowed by the configuration
    is: '6', you may want to alter your configuration.>
    How do we ensure our configuration is correct? Whenever this message is seen and
    the servers need to start. If we do not restart them, after a while they will
    hang and we need to restart them. Is there any way to resolve this issue? Thanks.

    Hi,
    Thanks for your info on Native IO.
    There is a JVM error message thrown when we are trying to do the thread dump.
    From the JDK website, we realise it is a bug for jdk 1.3.1. Thanks.

    When native i/o is used, there are a fixed number of threads that are
    dedicated to reading

    block waiting for
    data to arrive at a socket. In this case, if the number of sockets opened
    is greater than
    the number of threads available to read them, data on the remaining sockets
    will remain
    unread, until a thread becomes available to read it and response time
    will increase. This is
    basically what the message means.
    It is not surprising that performance has degraded by turning off native
    i/o. The message is
    not the problem - turning off native i/o is.
    I do not recall there being a problem with taking thread dumps with JDK
    1.3.1 - what
    indicates that the thread dump is not complete?

    As for your proposal to enable the native io and take thread dump,we have already

    Hi Arunabh,
    Our application server will use up the threads very fast and not
    releasing
    them
    after usage, causing our servers to hang once we enable native io.Thus we have
    no choice but to disable the native io. Is there any resolution
    for
    this? Is it
    due to we disable native io which cause the following message to
    appear?
    <ExecuteThread: '10' for queue: 'default'> <> <> <000000> <Thereare:

    Thanks for your prompt reply.

  • Connecting Java client to SSL server with existing certificates

    I am currently trying to connect my Java client to an existing server application
    written in C++. I have been provided the needed certificates (root.pem, server.pem,
    and client.pem). My code simply creates a SSLSocket and then attempts to read
    from it. Something goes wrong during the handshake process and I get a SSLHandshakeException. The certificates have been added to the keystore
    I am using, and I do not know any other action to take.
    Here is the debug output:

    Thread-4, handling exception: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

    (I am the original poster of this message, I had to create a new username though).
    The original problem had to do with incompatibilities with the protocol and/or cipher suites
    used. Now, the client and server perform most of the handshake process, but something
    goes wrong as the server requests the client certificate. In other words, the server requires
    mutual authentication, but for some reason it seems like my JSSE client won't send over
    it's client certificate. I don't get any type of bad certificate exceptions, so I'm not sure
    where the source of the error lies.

  • Need to communicate c server on linux & java client on windows

    Hi!! I am new to socket programing in both C and Java.
    From let I downloaded some client server example for c and java and tried that to link !! (I allways learn this way , and I need to do that little urget )
    though cient server in linux is working perfectly fine and same for java. But problem is when I tried to communicate C server on linux and java client on windows, I end up with getting some junk characters. Though they are connected successfully.
    Here goes code for java client:
    package whatever;
    import java.io.*;
    import java.net.*;
    public class Requester{
         Socket requestSocket;
         ObjectOutputStream out;

                   System.out.println("Connected to localhost in port 2004");
                   //2. get Input and Output streams
                   out = new ObjectOutputStream(requestSocket.getOutputStream());
                   out.flush();
                   in = new ObjectInputStream(requestSocket.getInputStream());

                             //System.out.println("server>" + message);
                             System.out.println("server>" + "message");
                             sendMessage("Hi my server");

    hii!! just trying to make it a little more explinatory
    1) what I am trying to accomplish by the above code is: - just need to echo/print from the Server , message send by the Client. I know code is not that good but should be able to perform this basic operation( according to me ).You are wrong. I told you that it won't work as long as you are using ObjectOutputStream and ObjectInputStream. You shouldn't write objects.
    2) Message sent by the client is "hello world"(hard coded).No, it's not. You are writing a serialized byte array.
    3) what I am getting at the client end is "*message recieved: ur*" (before that It shows the Ip of client machine)
    It should print "hello world ".See above.
    You are having a problem, and I have told you what the problem is.hey I dont know what went wrong but . I posted all this just next to my first post ...before you posted !!
    And hard coded byte array includes "hello world"...may be I am not able to explain properly.

  • Identifying Execute Queue Threads as Socket Readers

    Hi All,
    Preface: I am trying to identify at any given instance the percentage of
    socket reader threads that are in use - this will help me to identify when
    all threads are in use and unable to service user requests. Thus my goal is
    to identify threads that are socket readers and whether they are active or
    idle.
    Through JMX I can obtain an instance of each
    weblogic.management.runtime.ExecuteThread, which lists the same information
    that you see in the console if you drill down to the thread level, for
    example:
    mydomain> Servers> myserver> Active Execute Queues> default> Execute Threads
    That information includes:
    - thread number
    - total requests
    - last request
    - current request
    - transaction
    - user
    - is the thread idle?
    Now my question is from this information can you identify which of these
    threads are being used as socket readers?
    Here are some excerpts from my JMX calls:
    Name: ExecuteThread: '0' for queue: 'default'
    Execute Queue Runtime Name: default
    Current Request: null
    Last Request: Http Request: /bookstore/en/authors/showauthors.jsp
    User: null
    Is Idle?: true
    Name: ExecuteThread: '15' for queue: 'default'
    Execute Queue Runtime Name:default
    Current Request: null
    Last Request: Scheduled Trigger
    User: null
    Is Idle?: true
    Name: ExecuteThread: '26' for queue: 'default'
    Execute Queue Runtime Name:default
    Current Request: null
    Last Request: ListenRequest for a new connection on: 'Socket
    addr=127.0.0.1,port=2061,localport=7001]'
    User: null
    Is Idle?: true
    Name: ExecuteThread: '59' for queue: 'default'
    Execute Queue Runtime Name:default
    Current Request: Socket Reader Request
    Last Request:
    weblogic.transaction.internal.ServerCoordinatorDescriptor$2@138786
    User: null
    Is Idle?: false
    It would appear that the "ListenRequest" last request would identify a
    socket reader, only I have 60 threads in my default execute queue with 70%
    dedicated to socket readers and the number of threads that say their last
    request was "ListenRequest ..." is only 5.. Furthermore there is only one
    "Socket Reader Request" identified thread.
    Are threads identified as socket readers permanently or constantly reused
    for whatever purpose is required (with a cap of use based off of the socket
    reader perspective)?
    Thanks in advance for your help!

    Hi Achhi,
    Socket Reader Threads are the Threads which are responsible for reading the incoming request data. We can divide the Socket reader threads in two categories:
    Pure Java Socket Reqders: The pure-Java socket reader implementation, where the socket reader threads continually poll all opened sockets to determine whether they contain data to be read, even if the sockets have no data to read. (From Performance Point This is Not Good that the Sockets will be in Opened Mode even if there is no Data to read)
    Native Socket Readers: (These are the Dafault Socket Readers) The native IP socket reader provided by the host machine's operating system, where the socket reader threads target only active sockets that contain data to be read. Native socket readers never poll sockets because they are immediately notified when a socket needs to be serviced. For Better Performance You should always prefer using Native Socket Readers.
    To Enable Native Socket Readers You can Login to AdminConsole--->Servers ---><SERVER_NAME>--->configuration (Tab)--->Tuning (SubTab)---> "Enable Native IO" (This checkbox must be checked)
    Still If you want to use the Java Socket Readers .... still you can improve the performance of socket communication by configuring the proper number of socket reader threads for each server instance. For best performance, the number of socket reader threads in WebLogic Server should equal the potential maximum number of opened sockets.

  • Related to Network program using Java Client and C server

    I am little bit experience in java technology. I need an urgent help as I have to submit a document related to C server and Java client. But while searching in net i cant get a proper guidance for C server as many errors thrown in sys/socket.h and other new header files. Can any one help me out for giving source code for C Server. so that i can further involve in that document. Please help me out. i am really helpless by the way the C server thrown error. after finishing that C server only i can concentrate on Java client...

    Hai Josah,
    Thanks for your reply.. I have gone through many sockets server program in C but the real proble is the header file they include like
    socket.h and in.h etc.. they also provide these header files but if we compile in turboC they inturn require some other header files. I dont get the full hierarchy of C server program. I found some help in Java programming Archive about C Server and java client. As i am new to C i cant get the full header files for the server.c if i complete taht only i can proceed to java client. If u can redirect me for any good C sites also i can be thankful for u forever..please
