JDBC Query Running Indefinitely (Connection Missing)
Apr 3, 2007
We see an unusual case where a query seems to be taking a long time (more than 30 minutes) as shown by the Java thread dump (below) - however the SQL server DB does'nt show any corresponding Connection for the query at the lower layer.
The JDBC layer seems to be "in progress" as far as processing the results of the query are concerned. If the Connection was dropped or had a failure we should have seen a corresponding SQLException in the JDBC layer - which is also not the case.
Any tips on how to debug this? Is there a timeout set on the JDBC Connection which causes it to wait before it detects any failures?
thanks

My intention is to include a sql job to schedule for shrinking log files to half of its original log file size (if half of their original size is greater than 5MB)
The code is below. But while executing the code it is keeps on running indefinitely. can somebody throw some light what cause it to go into an indefinite loop.
Thanks
Babu
code:
====
DECLARE db_file_name CURSOR FOR
SELECT name , ceiling(size/128.0) * 0.5
FROM master..sysaltfiles
Where rtrim(lower(filename)) like '%.ldf'
DECLARE @f_name varchar(128), @new_f_size int
OPEN db_file_name
FETCH NEXT FROM db_file_name INTO @f_name,@new_f_size
WHILE @@FETCH_STATUS = 0
BEGIN
If ( @new_f_size > 5)
BEGIN
DBCC SHRINKFILE ( @f_name, @new_f_size )
FETCH NEXT FROM db_file_name INTO @f_name,@new_f_size
END
END
CLOSE db_file_name
deallocate db_file_name

HiI using Java and JDBC to connect to MS SQL server 2000 (using the MSdrivers msbase,msutil and mssqlserver.jars).Sometimes it takes a long time for statement.executeQueryto return and start returning the resultset(full DB scan can take 30-40 minutes).Does anyone know if it's possible to interupt/halt the query beforeit eventually comes back. The setQueryTimeout works OK but this has to beset quite high to allow real queries to run correctly. What I'm tryingto do is allow users to halt their query if they've realised theywant to alter it or its taking too long. The query is running in aseparate thread and I've tried using the main thread to close theconnection or stop the query but this still waits until the resultsetis returned.Maybe it's a driver issue or .....ThanksMike

When using jdbc with IntegratedSecurity, I run into this problem when the machine is not part of a domain & gets its IP address via dhcp. Is this expected behavior or a bug in the jdbc driver.
The SQLServer and client application are installed on the same machine and a local admin is logged in, running the client app.
If I change one of the two parameters mentioned above, the connection can be established leading me to believe this may be intentional for security issues. Am I correct?

Hi,
I am using sqljdbc_1.1 and am able to connect / query to my SQLServer 2000 database when I pass the "sa" userID and password in the connect URL.
String connectionUrl = "jdbc:sqlserver://<hostName>;databasename=mydb;user=sa;password=********";
However when I pass my username and password instead of the "sa" userID I get the following error (I edited out my userID from the error message):
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user '<userID>'.

I have tried passing the domain name with the userID and get the same error. I don't understand why the login would fail as I used my userID in a systemDSN on my laptop and had no problem connecting. I also used "SQL Server Enterprise Manager" configured to use my DOMAIN login information when I built the database.
Does anyone know what I could be doing wrong or what configuration I have overlooked?
Thanks,
RNG

Environment -
I am using Tomcat as my servlet engine and IIS as the Server. Additionally, I am using MS SQL 2000 as my DB. The DB resides on a seperate machine, and have created an ODBC JDBC connection on the local machine to access it. Additionally, the authentication for the DB is set to "Windows Authentication".
Problem -
Everything works fine if I simply run tomcat and access the databse. Also, things run fine when I run tomcat via IIS too. However, when I try accessing the database, I get the error
Login failed for user '<username>'
Now, the funny part is, this username is actually the username of the local machine on which the application has been placed. It is not the username that I am providing in
con=DriverManager.getConnection("jdbc : odbc : DBName","username","password"); /* had to add in extra spaces to stop this site from substituting :+D.etc to smiles*/
Can someone please help me figure it out?? Why is it working when I run the tomcat (Apache) and run the application from there, but ones I run it via IIS, it fails. Also, why is it taking the username from the local machine and not the one that I am providing out there?

Hi there,
i am working on SQL JDBC 2005 version 1.1. I have a liferay portal database located at server 1, wsrp portlets' database located at server 2 (with instance name instance1). The producer (liferay) have to create a connection with server 2 (use connection string) to authenticate the consumer. If the registration properties is valid, then the consumer are able to consume the wsrp portlet. (Note that i use tomcat as web container)
But when the producer connect to server 2, tomcat throws error:

Which {0}: server name
{1}: port,
......
for ex: jdbcqlserver://server2instance1,2345:2345;User=sa;Password=Sa;DatabaseName=mydb
Is my string correct ?
Note that the error occur intermittent, not everytime.
If any one there who have got or experienced with this error, please help me. Thanks you very much

Hi,
I have noticed that Connection.setTypeMap is not supported on the SQL Server 2005 JDBC driver.
The consequence is that it is impossible to use UDTs via JDBC. Is there any plan to implement this in the future ?

I'd recently upgraded SQL Server2000 to SQL server2005. I've been using Tibco DX to connect to the database. While working with SQL Server2000 things were going fine. I could access the databases from the repository through TibcoDX and could deploy my tasks which involved migrating data from source to target databases.
But when I had installed SQL server 2005 an error cropped up while deploying tasks
Exception occurred while initializing the JDBCTransformer: The TCP/IP connection to the host has failed. java.net.UnknownHostException:
I'd checked the port numbers and they were matching, the TCP protocols were also enabled. But I'm not able to fix this problem. Any help would be highly appreciated. Thank You.

Hello,
I've been developing a web application with a Java backend that connects to a SQL Server database with the JDBC driver 1.1 for a while now. Until now, everything was working fine. Now I had to add Windows authentication to the application.
After reading through the JDBC online help, I added the property
integratedSecurity=true to the connection string and copied the sqljdbc_auth.dll to the windowssystem32 directory of the system with the backend.
Logging in works fine, but the problem is that SQL statements that work on views throw SQLServerException errors, the message is
Invalid object name '(name of the view)'
It doesn't matter if a user is configured to log in via windows authentication or via SQL server authentication.
I need to access those views instead of the real tables because this is part of my security concept, the database creates views for each user based on his role.
Is this a known problem with the JDBC driver or a configuration issue?
Thanks for the help.

Hello. I have recently installed MS SQL SERVER 2005 and when I was installing it, it asked me for the username and password, and there I had 2 options: either write my own, either select "Use Windows Authentification". I selected the "Windows Authenthification" ( I guess that means that it uses my username and password from Windows ).
Now, Im trying to connect to the Server using Java and JDBC, but I have a problem: I have to specify the username and the password of the connection! My windows' only account is "Vlad" and I have no password. I tried these options, but it didn't work. I also tried with empty string "", and with "sa", "sa" but it didn't work either. I get an error saying that "Login failed for user 'Vlad'. The user is not associated with a trusted SQL Server Connection."
Any ideea of what the username/passwords are or how to get them?.
Thank you for your time.

In testing new patches, I tried Windows 2003 Server SP2 and our JDBC connections stopped working. I uninstalled SP2 and they started working again. Anyone know where the problem is?
I have already read pages of documentation, but I will keep looking. Please let me know if you know the setting that needs to be changed. I'm assuming it is a new "security enhancement" but I'm just not sure exactly where.
Thanks in advance.

Hi!
I'm writing a java application that queries sqlserver 2005 (and 2000). In case the sql browser service is stopped I need to use the named pipe property or the port property, right?
But how could the program know at runtime what is the port and what is the pipe name? And how should a connection string to sqlserver 2005 (and 2000) that includes named pipe, look like?
Thanks!

Hello,
I have MS SQL Server 2005 with SP1 installed, version 9.0.2047
I am trying to debug a Script Task in SSIS.
I have break point on the first line of the code.
SSIS runs and eventually launches MS Visual Studio for Applications.
Line with the break point is highlighted in yellow.
After that Visual Studio is frozen. F5, F11 or any other key press produces a popup which says the following:
Delay notification.
Microsoft Visual Studio for Applications is waiting for an operation to complete. If you regularly encounter this delay during normal usage please report this problem to Microsoft. Please include a description of the work you were doing in Microsoft Visual Studio for Applications and when possible instructions how to reproduce this delay.
If Microsoft Visual Studio for Applications is waiting on another application you can switch to that application now, or you can continue waiting for this operation to complete.
The popup has to buttons: [Switch to€¦] and [Continue Waiting]
None of the buttons allows to proceed.

If I start a long running query running on a background thread is there a way to abort the query so that it does not continue running on SQL server?
The query would be running on SQL Server 2005 from a Windows form application using the Background worker component. So the query would have been started from the background workers DoWork event using ado.net. If the user clicks an abort button in the UI I would want the query to die so that it does not continue to use sql server resources.
Is there a way to do this?
Thanks

I am having MSSQLServer2000 on Win2k and Win2k3 server.
i have to connect these servers from a application using JDBC driver and AD Authentication.
I have programmed all the things needed for AD authentication in my application(changed url , using integratedSecurity=true), and it is working fine when my application connects to MSSQLServer2k5 on WinXP(which is added to same domain of my application).
But when i try to connect MSSQL2000 server on Win2000 server it failes and gives error as follows.
Apr 18, 2008 12:39:51 PM com.microsoft.sqlserver.jdbc.AuthenticationJNI SNISecGenClientContextINFO: Failed to get the SPNcom.microsoft.sqlserver.jdbc.SQLServerException: Connection reset at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSChannel.read(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSReader.readPacket(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSReader.readPacket(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSReader.readResponse(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSCommand.startResponse(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSCommand.startResponse(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.sendLogon(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.logon(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.access$000(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection$LogonCommand.doExecute(Unknown Source) at com.microsoft.sqlserver.jdbc.TDSCommand.execute(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.connectHelper(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.loginWithoutFailover(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerConnection.connect(Unknown Source) at com.microsoft.sqlserver.jdbc.SQLServerDriver.connect(Unknown Source) at ChangePassword.process(ChangePassword.java:33) at ChangePassword.main(ChangePassword.java:14)
I am using following code for connection --
String url = "jdbcqlserver://172.16.1.243\dbaudit;portNumber=1034;integratedSecurity=true";
Class dbDriverClass = Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Driver driver = (Driver) dbDriverClass.newInstance();
Properties props = new Properties();
conn=driver.connect(url, props);

I have read similar posts to this, but I am still having problems.
I am trying to use connection pooling to connect to a local SQL Server 2005 database. I am running my application using
MyEclipse Enterprise Workbench. I have verified that sqljdbc.jar resides in "WebRoot/WEB-INF/lib/"

Code to connect:

public int testConnect(){
Connection conn = null;
InitialContext ctx = null;
java.sql.Statement stmt = null;
try {
ctx = new InitialContext();
Context envCtx = (Context) ctx.lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/DefaultDS");/*This is generating the Cannot load JDBC driver class... error*/
conn = ds.getConnection();
stmt = conn.createStatement();
return CONSTANT.SUCCESS;
} catch (Exception e) {
return CONSTANT.FAILURE;
}finally {
try {
if (stmt != null)
stmt.close();
if (conn != null)
conn.close();
if (ctx != null)
ctx.close();
} catch (Exception ex) {
// do nothing
return CONSTANT.FAILURE;
}
}
}
Any ideas would be greatly appreciated.

I'm trying to connect to DB2 database across a vpn. When I test locally there's a connection manager: "Native OLE DBMicrosoft OLE DB Provider for DB2" option that I assume will work. I actually need to do this on a remote computer that is able to authenticate with AD to connect to a couple other DBs, and on that install there're no DB2 connections to be found.
Any ideas on why the list of available connections on that install would be different? Do I have to put the drivers in the classpath then to get SSIS to pick them up?

Hi all,
I used the CreateUserWizard control to create new users. It amazes me how powerful the control is.
What amazes me most about this is that the control is smart enough to save the users info to the ASPnetdb.mdf.
I thought the connection string is stored inside the web.config. But once I opened the file, I can't find the connection string.
Where has the connection string gone? Can someone enlighten me? Thanks.

I need to Query tables in 2 databases after getting a connection. I cannot make this piece of code to work. In db2, oracle this type of code works.
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
String sys = “jdbc:microsoft:sqlserver://192.168.0.152";
conn = DriverManager.getConnection(sys, "name", "pswd");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM pubs.jobs");
rs = stmt.executeQuery("SELECT * FROM mydb.myfile");
If I run this I get invalid object “pubs.jobs” error.
Any ideas?
Thanks.

Hi all,
We've just stumbled on a 1.0 version incompatibility with the JDBC specs.
Problem: A table with SMALLINT column. According to JDBC specs version 3.0
(p.B-179) and 4.0 (p.221)), the value should be converted to Integer type.
Unfortunatelly we get a Short object :(
Now, I remember, this case was also affecting old JSQLConnect driver from
DataDirect. Could that problem sneak to new MS driver too?
Please let me know any resolution to this problem if exists.
The issue has not been fixed in CTP 1.1 version. Any ideas if it can be fixed??
Cheers,
Piotr
