Java.sql.SQLException: I/O Error: Connection reset on MS-SQL Server 2000

Anybody able to help me with this Java-JDBC Problem?
I'm creating a ResultSet and execute a query which approximatelly delivers me 11.000 rows.
With the given ResultSet i'd like to move through the records forward only.
In my while loop I'm able to reach ~9700 rows and then unexpectedly i get the error:
java.sql.SQLException: I/O Error: Connection reset

... 4 more
I'm using the jTDS JDBC driver.
I googled a lot but didn't found a solution for this problem?
So please help me!
Thanks in advance

  • Java.sql.SQLException: E/A-Exception: Connection ended abnormally

    Hi all,
    this strange exception occurs in the communication channel monitoring. I see there was a processing error in the communication channel which inserts data from XI. When I look in audit protocol I can see that after a few minutes the connection is ended with an error which says the following:
    Error processing request in sax parser: Error when executing statement for table/stored proc. 'LVS' (structure 'STATEMENTNAME'): java.sql.SQLException: E/A-Exception: Connection ended abnormally.
    Now my questions are: Why does this error occur? And can someone explain me this error?
    Regards
    Florian

    I think I have the reason for this problem. It's a network problem. The network to this system has a high load. In addition, the JDBC receiver adapter was configured with parameter <i>"Disconnect from Database After Processing Each Message".</i> Now I have deselected the parameter and I have no problems.
    Thanks for your efforts
    Florian

    RT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE)))
    OK (10 msec)
    dont understand what the reason of problem. read many forums and try this and that but can't resolve it (haven't enough knowledges :( ).

  • Socket read error: connection reset by peer

    Hi.
    Has anybody experienced the error message �Socket read error: connection reset by peer�
    Please see below for detailed information.
    Appreciate your help
    Regards
    RT
    Enviroment specification
    Server: HP/UX 11.00 64-bit, Oracle RDBMS 8.1.6.0.0 64-bit
    2 firewalls between client and db.
    Client:
    Win 2000,
    SP3,
    Oracle Client 8.1.7.0.0 ,JDBC OCI (thin JDBC driver,class12.zip)
    JDK 1.3
    JRUN3.0
    The TCP protocol is being used in the communication
    Error messages
    Web Users receive:           Socket read error: connection reset by peer
    Trace files on the sever:      Read unexpected EOF ERROR on 18.
    Explanation: The error in the server sqlnet trace file, suggests that a client connection has terminated abnormally, i.e. client machine powered off, a cable removed or a network connection aborted without warning. No user has complained of such a problem and there is no client trace with an error.
    The problem
    The users of the java web application, experiencing an exception almost once or twice a day.
    The JRUN web-server reports broken connections to the db and client are receiving "connection reset by peer".
    At the moment when the errors occurs the users just have to wait a while(2-10 min) and then they can use the web application again.(no action is taken)
    This problem can not be reproduced. The problem happens only occasionally when the network is under heavy load and new DB connection is being created.
    The application
    The java web-application uses a customized connection pooling against the database. This pool is shared among all the users of the website. whenever a user process needs to fetch data from the database, a free connection from this pool is allocated. The application is testing if the connection is valid before making a transaction (select '1' from dual). When the error occurs a ORA-3113 end-of-file on communication channel is returned to the application.
    The path between the client and db involves at least two firewalls. The firewalls are opened for sql*net traffic. The network group can tell that enquiries from the app.server is not getting feedback from the db. They have not however, identified if the enquiries are reaching the db-srever, or if they are stopped earlier in the network.
    Around 1000 users, are using other applications which uses dedicated sqlnet connections against the db and they have not experienced any problems.
    Issues considered
    Connection pooling
    It is a customized connection pooling, developed by Lindorff developers.
    I have read through the source code for the connection pooling and it does the job as it should, and in case of bad connection, it tries to create a new connection.
    The log file shows that the call to the method DriverManager.getConnection() hangs until the server goes down, which is probably because of the fact that the method DriverManager.setLoginTimeout(), does not take effect and timeout value is Zero. ( According to oracle , Oracle JDBC does not support login timeouts and calling the static DriverManager.setLoginTimeout() method will have no effect).
    Firewall
    One thing to consider is when the firewall may decide to shut down the socket due to long inactivity of a connection. This will cause problems to JDBC Connection Pool because the pool is not aware of this disconnection at the TCP/IP level; until someone checks out the connection from the pool and tries to use it. The user will get a Socket read error: connection reset by peer.
    Jrun timeout paramter is less than the firewall�s timeout so the firewall will not close a connection before Jrun does.
    Number of processes the DB can handle
    Processes parameter is 1300, , they have not experienced the Oracle error msg �max # of processes reached�.
    Port redirection through a firewall:
    Since the firewall has a sql net proxy Port redirection through a firewall is not a problem. Problems with port redirection only appear at connect time, but in this situation the connections fail long after the connection is established.
    The network group
    The network people who investigaged the problem at Lindorff report that there are a significant amount of "dropped packages" between the database server and the jdbc client (web-application) 24 hrs. The reason for this is "unknown established TCP packet" which means that the firewall does not consider these packages to be part of an already established session. The network group believes this happen because one of the hosts send a RESET or FIN signal which the firewall have noticed but are not received by the other host.
    It seems like the firewall are dropping packages bacause of "Unknown
    established TCP packet" from both the JDBC client and the TNSLISTENER on the database server. The dropped packages are SQL*Net v2 traffic so clearly Oracle products are involved

    Presumably something is working.
    Thus the problem is not with your code. At least not the database part that you have control over.
    That error occurs when the other side closes the socket. Presumably you are catching lost connection exceptions and trying to restore it.

  • HTTP response error :Connection reset

    Hi all,
    I am getting following error in log while sending message to the trading partner and the main problem is that once this error comes then after that I am not able to send any more message to any of my Trading Partners. Even if I try to send message to any other Trading Partner, nothing comes in the B2B log and report as well. After restarting the B2B I am able to send message again to other Trading Partners.
    Can anyone please tell the reason for getting this error? I also want to know that after getting this error once, why am I not able to send message to any Trading Partner?

    Hi Sinkar,
    Thanks for the reply. I confirmed it with my Trading Partner and their server is not running but still I want to know that why am I not able to send message to any other Trading Partner after getting this error once. And if I restart the server, it again acts normally and I am able to send message to other Trading Partners.
    SSL is configured properly because I was able to communicate with this Trading Partner earlier when their server was up.
    We are working on 10.1.2.3.0 with 7457066 MLR 5 patch. Please guide if any other patch required.
    Thanks for the help.
    Warm Regards,
    Anuj Dwivedi

  • Netscape Error: Connection reset by peer

              I am running a JSP application on weblogic and when I view in Netscape 4.08 on
              W2K I am getting an error saying Netscape Error:Connection reset by peer. Anyone
              else see same error. Any fixes?
              

    do u see this on the 5.1 line ?
              Netscape needs a content-length for every response that comes in, and in case the
              response is larger than the buffer size, the content-length isnt set and netscape
              keeps hovering even after getting all the data.
              When it sees that the connection has been closed from the other side, it thinks that
              the connection has been reset. (even after the server sends it a Connection: Close
              header)
              solns can be summed up as:
              1. call response.setContentLength whereever possible
              2. increase the buffersize of jsps (there might be an upperlimit though)
              3. move to another version of netscape (atleast > 4.7 ) on win2k
              let me know how the workarounds are
              thanks

  • POSIX error: Connection reset by peer

    Hi,
    I have the following error appear when I download images from a website and get this error in the download palette:
    POSIX error: Connection reset by peer
    Does anyone know what this is?
    Is is the website causing it or my Mac?

    If it only happens from a given site, then it is the site. If it happens all the time, then it is either your Internet connection or your Mac.

  • Im geting the error"Connection reset by peer" in apex 4.1 due to javascript

    Hi
    I have problem in oracle apex(4.1) page. If I write the following javascript code in the HTML Header and Body Attribute and click apply changes it show error like
    =====Error======
    Connection reset by peer
    Description: Connection reset by peer
    =====javascript Code=========
    <script type="text/javascript">
    function altmsg()
    alert('test');
    </script>
    ================
    if I remove the script tag alone that is <script type="text/javascript"> and </script> by leaving the function altmsg() as it is in the HTML Header and Body Attribute ,then again if I click the apply changes it is showing the following error
    =========Error======
    Error ERR-3331 This page was already submitted and can not be re-submitted.
    Continue
    OK
    ==================
    If I put the same code without script tag in JavaScript block(Function and Global Variable Declaration) in the edit page and click apply changes then the same error(Error ERR-3331 This page was ...) is showing.
    Im getting this issue for couple of days. Before that it was working fine.
    Thanks

    Hi Balaji,
    I was not really able to reproduce this issue when I connect to your workspace and modify page 1 of application 55837.
    I'm able to paste your JavaScript code into the "Page HTML Body Attribute" attribute and I'm also able to append the code to your existing JavaScript code in "HTML Header". I'm using Google Chrome.
    What do I miss? Are you sure that it's not some Firewall/Antivirus software is kicking in and prevents the submission of the page?
    Regards

  • Java.sql.SQLException: The TCP/IP connection to the host  has failed.

    Hello. I hope you had a happy new year! Now its back to work.
    I am having a problem connecting to a remote SQL Server DB. I am using NetBeans 5.5 and the latest J2EE. I am able to see the tables in the IDE and bind objects to data. But when I run it it gets this:
    java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: no further information
    at com.sun.gjc.spi.DataSource.getConnection(DataSource.java:100)
    at com.sun.sql.rowset.internal.CachedRowSetXReader.connect(CachedRowSetXReader.java:344)
    at com.sun.sql.rowset.internal.CachedRowSetXReader.readData(CachedRowSetXReader.java:126)
    at com.sun.sql.rowset.CachedRowSetXImpl.execute(CachedRowSetXImpl.java:968)
    at com.sun.sql.rowset.CachedRowSetXImpl.execute(CachedRowSetXImpl.java:1428)
    I checked the SQL Server Configuration manager on that machine and TCP/IP connections are allowed. What else could be wrong?
    Thank You.

    "Connection refused" means that the client sends a packet saying "I would like to connect to port number NNNN please" to the server computer, and the server computer's OS sends the reply "there is no process listening to that port on the network interface you are using".
    The database server is not running, or running but not listening to TCP/IP connections, or at a different port from what you think, or listening to only selected network interfaces (it is possible for a process to listen to a specific interface or a wildcard for all interfaces). A less likely scenario is that a firewall is sending the "connection refused" message.
    First aid check list for "connection refused":
    - Check host name in connect string.
    - Check port number in connect string.
    - Try numeric IP address of server host in connect string, in case name server is hosed.
    - Are there any firewalls between client and server blocking the port.
    - Check that the db server is running.
    - Check that the db server is listening to the port. On the server, try: "telnet localhost the-port-number". Or "netstat -an", there should be a listening entry for the port. You need to configure the database to accept TCP connections; the server documentation or google should explain how.
    - Try "telnet server-host-name the-port-number" from the client, to see if firewalls are blocking it.
    - If "telnet" fails: try telnet with the numeric ip address.
    - If "telnet" fails: does it fail immediately or after an obvious timeout? How long is the timeout?
    - Does the server respond to "ping serverhost" or "telnet serverhost" or "ssh serverhost"?

  • Java.sql.SQLException: ORA-00933: error when  executing query

    Hello,
    I am trying to execute the following query from a jsp page.
    String sqlUpdate ="UPDATE table_name SET name ='"+name+"', description='"+description+"', proj_link='" projlink"', active='" active"',sort_order='" order"',image='" image"',category='" category"', technology='" technology "' WHERE id="+id+" ";
    stmt.executeQuery(sqlUpdate);
    I get the follwoing error java.sql.SQLException: ORA-00933: SQL command not properly ended
    When I omit "description" from the query it executes fine. But when I place it back into the query I get the above error. The table is in Oracle database and the datatype of description id varchar2(4000). I declared all the variables used in the query, I then assigned values caught from the form and then am trying to update the form varibles in the table.
    Thanks,

    I am trying to execute the following query from a jsp page.There's a big part of your problem. You shouldn't be doing database stuff in JSPs. If you must, you should be using JSTL and its <sql> tags.
    String sqlUpdate ="UPDATE table_name SET name ='"+name+"', description='"+description+"', proj_link='" projlink"', active='" active"',sort_order='" order"',image='" image"',category='" category"', technology='" technology "' WHERE id="+id+" ";Not using PreparedStatement here is just a silly noob error.

PreparedStatement will eliminate that problem.
