How to set the timeout to execute sql by jdbc?

Connection con = getConnection();
Statement stmt = con.createStatement();
stmt.execute("update table1 set colum1='abc' where key = '1' ");before run this java class
I exectue the sql(update table1 set colum1='abc' where key = '1' ) in sqlplus
but not commit.thus the database will lock the item .
then I run the java class.
so the class will waite the sqlplus commit.
I want kill the run thread when the java class waite 1000 seconds.
how can I do?

o
I have tried it.
but it seems the method can not work well
if I use
stmt.setQueryTimeout(30) the jdbc operate will be cancled after 4 minutes not 30seconds

    Right-click the WINDOWS desktop, choose New->Microsoft Data Link. That will bring up a dialog that allows you to configure and test your database connection. You might connect to the Access database via ODBC or directly via Jet Engine. The Jet Enginge saves you the trouble of creating an ODBC connection on your PC. After you leave the dialog, the "data link" will show up on your desktop as text file. Open it and copy-paste the connection string to your VI.
    This webpage is an excellent resource for connection strings: http://www.able-consulting.com/ADO_Conn.htm
    If your application requires users to change the database connection at runtime, you can also include the dialog via ActiveX (MSDASC.IDataSourceLocator).

  • How to export the result from executing sql statement to excel file ?

    HI all,
    Great with Oracle SQL Developer, but I have have a trouble as follwing :
    I want to export the result from executing sql statement to excel file . I do easily like that in TOAD ,
    anyone can help me to do that ? Thanks so much
    Sigmasvn

    Hello Sue,
    I just tried to export to excel with the esdev extension and got java.lang.NumberFormatException. I found the workaround at Re: Windows Multi-language env, - how do I set English for application lang?
    open the file sqldeveloper\jdev\bin\sqldeveloper.conf and add the following two lines:
    AddVMOption -Duser.language=en
    AddVMOption -Duser.country=USyet now my date formats in excel are 'american-style' instead of german. For example 01-DEC-01 so excel does not recognize it as date and therefore I can not simply change the format.
    When export to excel will be native to 1.1 perhaps someone can have a look at this 'feature'

  • ORDS 3.0 - How to set VPD Context before executing SQL Template?

    I need to set a couple of attributes in an Oracle Session Context before the SQL/PLSQL template handler is executed, as we rely on Oracle VPD/Row-Level-Security for the data access.
    Is there a hook/functionality in ORDS 3.0 where I can register a PL/SQL (e.g. set_security_context(authenticated_user)) procedure, so this 'set_security_context' procedure is executed before and for each execution of a SQL/PLSQL template handler?

    I tried to log the request at Oracle REST Data Services (ORDS) but I could only start a new discussion: Possibility to register Pre-/Post-Procedures for an SQL Template Handler
    As I mentioned there, the PL/SQL handler approach works for me as long as I have no or only little data to send back to the client (e.g. put/post/delete succeeded or an error message why the call failed).
    If I need to return a lot of data from the PL/SQL handler I would need to, as far as I understand, to marshal the data to JSON and write it to the response body in the PL/SQL handler.
    I don't want to do the marshaling, because ORDS does it better.
    However, this works for me:
    I write a pipelined stored procedure that takes as input the attributes I need to set in the session context. I then can reference it in the SQL handler:
    select * from table(my_pipelined_function(:USER, ....)
    Now the JSON/HTTP response is created by ORDS again.
    I still needed to code a couple of lines, but it is way better than duplicating the functionality already existing in ORDS.
    With the hooks it would be perfect because I would not have to write any code (apart from the procedure to set the session context attributes), just configure the REST services in ORDS.

  • How Track&monitor the history of executed sql /plsql on 10g database server

    I want to keep and track the history of all sql/plsql that is being execute on database server. how it is to be done.
    pls help
    prabhaker

    To keep track of executed SQL statements, you can use database auditing : see http://oraclelon1.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4007.htm#i2059073
    I am not sure that PL/SQL execution can be traced using database auditing.

    Hi Timo,
    My jdev version is 10.1.3.3.0, this is for R12. By PR i mean to say process request and PFR process form request in the controller.
    In the Process request of the controller, i am finding the checkbox bean and assigning the firepartialaction for it.
    Later in the process form request for the fired event, i am trying to handle the rendered property of the messagetextinput. Is this a right approach?
    my code below
    public void processRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
    super.processRequest(oapagecontext, oawebbean);
    OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
    OAMessageCheckBoxBean oamessagecheckboxbean = (OAMessageCheckBoxBean)oawebbean.findChildRecursive("X_FLAG");
    if(oamessagecheckboxbean != null)
    oapagecontext.writeDiagnostics(this, "Message check box Bean found:", 1);
    FirePartialAction firepartialaction = new FirePartialAction("change");
    oamessagecheckboxbean.setAttributeValue(PRIMARY_CLIENT_ACTION_ATTR, firepartialaction);
    oamessagecheckboxbean.setFireActionForSubmit("change", null, null, true);
    oapagecontext.writeDiagnostics(this, "setting fire event", 1);
    public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
    super.processFormRequest(oapagecontext, oawebbean);
    oapagecontext.writeDiagnostics(this, "Inside Process Form Request", 1);
    if("change".equals(oapagecontext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
    OAMessageTextInputBean bean = (OAMessageTextInputBean)oawebbean.findChildRecursive("X_NUMBER");
    if(bean!=null){
    bean.setRendered(Boolean.TRUE);}
    Thanks,

  • How to set the actioncommand self execute?? (Urgent)

    Please see code below, if i click button after perform "e.getActionCommand().equals("update")", i want run the "e.getActionCommand().equals("cancel")" .Can i do that???
    public void actionPerformed(ActionEvent e){
            if (e.getActionCommand().equals("update"))
                    temp.commit();
                         temp.close();
                         l_status.setText("Saved");
                         l_status.setForeground(Color.blue);
                         log=0;
           if (e.getActionCommand().equals("cancel"))
                    if (log==1)
                         temp.close();
                         p1.removeAll();
                         p1.add(label1);
         p1.add(menuBar);
                         p1.repaint(); 
                         log=0;
         }

    I just want to add a code in "update" portion to make
    "cancel" run also, possible??Why not having two methods?private void update() {
        temp.commit();
        temp.close();
        l_status.setText("Saved");
        l_status.setForeground(Color.blue);
        log=0;
    private void cancel() {
        if (log==1)
            temp.close();
        p1.removeAll();
        p1.add(label1);
        p1.add(menuBar);
        p1.repaint(); 
        log=0;
    }That way, you can perform update or cancel as you want. For example:public void actionPerformed(ActionEvent e) {
        if (e.getActionCommand().equals("update")) {    
            update();
            cancel(); // <- you can add cancel here
        else if (e.getActionCommand().equals("cancel")) {
            cancel();
    }

  • How to set the number of seconds a servlet is allowed to run

    I use JSP to generate a report, but it will take about 10 minutes to search.
    IE Client screen displays an error message what is "Cannot find out your page" after 8 minutes. How to set the number of seconds a servlet is allowed to run.

    It's not a matter of how long the servlet is running... it's the browser timing out because the servlet hasn't responded to its request.
    You have several options:
    1) "Browser Pinging"
    Your servlet sends some small data which can be either seen or unseen (html comments, hidden chars, etc) by the user at short intervals while your report is running. When the report is finished, the browser will not have timed out because it has been "snacking" on those small bits of data which tell the browser its original request was both heard and being handled. I don't think there is any timeout in IE as long as it receives data continually (or at least before its own timeout mark over and over again...)
    2) Multithreaded processing
    This would probably be a better approach. Have the report run in a separate thread running on the server. You'd want to store a reference to this executing report in the user's session. Instead of making the browser wait for the report to be finished, have the servlet check the user's session to see if a report exists and is running. If one does not exist, create one and start its execution. If one does exist, and is still running, print a "please wait" type of message OR an animation, etc... along with some javascript which will reload the page every few seconds. If the page reloads and the servlet sees that the report is finished, it can then display it to the user.
    Hope this helps,
    -Scott

    ejp wrote:
    Because, there's no FTP client command that allows to do such thing.Socket.setSoTimeout().I agree with you on this one but the OP is talking about the FTPClient API from Apache.
    To the OP,
    BTW, I have reread the Javadoc about the [*API*|http://commons.apache.org/net/api/org/apache/commons/net/ftp/FTPClient.html] : indeed, there's no setTimeout method, but there is a setDataTimeout method : +Sets the timeout in milliseconds to use when reading from the data connection+ .

  • How to setup the timeout time about container mangement transaction?

    hi
    i want to modify the time-out time about cantainer management transaction.
    but i don't know where and how to setup it....
    please tell me how to do it, thanks a lot.
    Joe

    We haven't been using the session pool, just the direct Jolt classes, but
    the only way we've found to set the timeout is via a transaction time, it
    seems to be the only one that has any effect.

    10.5 Date, Time, and Timestamp
    The JDBC API follows the Java platform's approach of representing dates and times as a millisecond value relative to January 1, 1970 00:00:00 GMT. Since most databases don't support the notion of a time zone, the JDBC 2.0 API adds new methods to allow a JDBC driver to get/set Date, Time, and Timestamp values for a particular time zone using a Calendar. For example,
    ResultSet rs;
    Date date1 = rs.getDate(1);
    returns a Date object that wraps a millisecond value which denotes a particular date, like January 3, 1999, and a normalized time 00:00:00 in the default time zone. The time component of the Date is set to zero in the default time zone since SQL DATE values don't have a time component. Since a Calendar was not supplied explicitly to getDate() , the default time zone (really the default Calendar) is used by the JDBC driver internally to create the appropriate millisecond value assuming that the underlying database doesn't store time zone information.
    The following example retrieves a date value in GMT-Greenwich Mean Time.
    ResultSet rs;
    TimeZone.setDefault(TimeZone.getTimeZone("GMT"));
    Calendar cal = Calendar.getInstance();
    Date date2 = rs.getDate(1, cal);
    In the example above, a Calendar is passed explicitly to getDate() to inform the JDBC driver how to calculate the appropriate millisecond value. Note that the same result could have been achieved by simply changing the default time zone, and not passing the Calendar explicitly since the JDBC driver will use the default time zone by default.
    Note that the two Date objects created above will not compare as equal assuming that the default time zone is not GMT, even if they represent the `same' date.
    if (date1.equals(date2))
    //never get here
    This is because each Java language Date object really just wraps a normalized millisecond time value and these millisecond values will differ across time zones. If an application wishes to compare dates in different time zones it should first convert them to a Calendar.
    An application should create a Date object using a Calendar. The application is responsible for specifying the time as 00:00:00 on the desired date when using the Calendar since JDBC uses this convention. In addition when creating a Time value the application must specify a date of January 1, 1970 to the Calendar used to create the millisecond value for the Time as this is the convention specified by JDBC for time.
