Test Plan.
Add one Thread Group with default settings.
Add JDBC Connection Configuration with below setting.
Add JDBC Requset for Simple select stement.
Add Constant Timer with 5000 miliseconds Thread Delay.
Add View Results Tree.
My DBServer Name : proddbtest1.xyz.com
SQL Instance Name: Prodbtest1\LIVE
I fill up this parameter value in DB URL and Driver class. In fact I download latest JDBC sqljdbc42.jar from Net and past at Lib folder.
After running my test plan still I get an error message
"java.sql.SQLException: Cannot load JDBC driver class
com.microsoft.jdbc.sqlserver.SQLServerDriver"
Can any one help me where I am passing wrong configuration settings.
As per Using the JDBC Driver article the correct Microsoft JDBC Driver class name is:
com.microsoft.sqlserver.jdbc.SQLServerDriver
you are trying to use the following one:
com.microsoft.jdbc.sqlserver.SQLServerDriver
^^^^^^^^^^^^^^
So replace jdbc and sqlserver and your setup will work.
Also don't forget to restart JMeter to pick the sqljdbc42.jar up.
Just in case see The Real Secret to Building a Database Test Plan With JMeter article to learn more about database load testing using JMeter

I perform Star Schema Benchmark to test ours DB product. I perform Star Schema Benchmark query concurrency test in jmeter.How do I set up SSB SQL to be executed concurrently in JMeter？
If you want to execute Star Schema Benchmark sample queries from JMeter you will need to:
Copy the JDBC driver for your "DB product" to "lib" folder of your JMeter installation (or any other folder in JMeter Classpath)
Add JDBC Connection Configuration and specify:
your "DB product" instance JDBC URL
fully qualified class name of the JDBC Driver
credentials
other options like pool size, timeouts, etc.
Add JDBC Request sampler and put your query there (one query per Sampler)
Now increase the number of users/loops in the Thread Group according to your workload model and run your test

How to use Different JDBC Drivers
For one of the test plan, I have 1000's of records. It would be helpful to have bulk update. Has anyone implemented it or know of how to implement it in Jmeter. Also, can prepared update statement be used to achieve it?
You just need to follow the given below steps to create a JDBC test plan.
1) Firstly, Download the JDBC Driver for SQL Server from Microsoft site.
2) Once the JDBC Driver is downloaded extract to find the .jar file of driver.
3) Now, open the Jmeter and create a test plan.
4) Select the test plan node and there is a section "Add directory or jar to classpath", browse the extracted JDBC Driver and select it.
5) Create a thread group and add config element "JDBC Connection Configuration" and configure according to your requirement.
6) Make sure to provide the variable name.
7) Now, Add a JDBC Request from the samplers in thread group section and use the same variable as you mentioned in the "JDBC Connection Configuration".
8) Select the query type as "Update Statement" from the drop down.
9) Mention your query in the editor panel.
10) Finally, add the listener to trace the output of your test plan and execute the test.
Hope this will entertain your question.
I'd like to know the mechanism of performance testing Database by Jmeter, so need your help on my concern as below:
Q1. Does Jmeter will access directly to Database for testing ? Or,
it will access to database via a website having database URL (as the Database URL on JDBC request config) ?
Q2. which fields will be tested in Database : capacity or Database structure or others ? - please explain in advantage.
Besides, Jmeter is a good tool for testing database ? - which cases / why should we use ?
Thanks,
Q1: JMeter has JDBC Request sampler which can connect to database directly assuming appropriate JDBC driver in JMeter classpath and proper JDBC Connection Configuration
Q2: It's totally up to you as JMeter doesn't test anything. If you specify a query or a set of queries under Transaction Controller JMeter will report the time which queries took under the load and errors if any.
We are running applications on weblogic server. We have a requirement in which we want to monitor jdbc calls made on a data source. We only want to collect time taken for each sql to execute and number of times a sql is fired. I also want to collect this information per user session.
There are a few utilties on the web like weblogic jdbc spy, log4jdbc, etc. But they all required additional setup on the data source and provide output on a separate logging file which does not contain per session output as such. Is it possible to create another weblogic application that listens on a given data source and record all the sql and the timings per session? Please provide any pointers that you have.
TIA,

Oracle JRockit Flight Recorder can be answer for you. I'm using him. Just make a record in defined time and then analyze gathered jfr file with Oracle JRockit Mission Control.

Or you can find your answer with parameter -Doracle.jdbc.Trace=true -Djava.util.logging.config.file=/jdbc/demo/OracleLog.properties
Hi guys:)
I am new to servlet.I dont know how to connect oracle database to the servlet application. Can anyone paste Oracle JDBC coding
Register Database Connection parameters:
To include your application specific connection parameters of your database, edit the file data-sources.xml under \config directory. Add the following lines to create a data source. Change the hostname, port, username/password, database name, driver type to suit your application. Make changes for url after # symbol. Save the file. This will register the data-source which can be used across your application.
<data-source
class="oracle.jdbc.pool.OracleConnectionPoolDataSource"
name="ifso817DS"
location="jdbc/Loneifso817DS"
xa-location="jdbc/xa/ifso817XADS"
ejb-location="jdbc/Pooledifso817DS"
url="jdbc:oracle:thin:#insn104a.idc.oracle.com:1521:ifso817"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="travel"
password="travel"
inactivity-timeout="30"
/>
That is taken from: http://www.oracle.com/technology/sample_code/tech/java/servlets/samples/TravelServlet/Readme.html
There are a lot of articles discussing this, but I'll give you the basic steps:
download Oracle JDBC driver from Oracle's homepage, it's called ojdbc6.jar if you're using Java 6
make sure your application can find it on its classpath
since you are using servlets, you're also using a Java application server; read relevant documentation about setting up a JNDI binding to your database (usually this binding will be called jdbc/connectionName)
inside of your application, use this code:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/connectionName");
Connection conn = ds.getConnection();
This should be enough to get you started.
For more information, Google is your friend. Check out Wikipedia's JDBC page. Google "Oracle JDBC connection" for more info.
One thing that might give you headaches if you've never done stuff like this: when defining Oracle's URL for your app. server, it's format is as follows:
jdbc:oracle:thin:[user/password]#[host][:port]:SID
So you have to substitute appropriate values when defining the connection for a JNDI binding.
check this http://www.java2s.com/Code/Java/Servlets/JDBCandServlet.htm. You need to modify driver class name and connection url to connect to Oracle DB. Check http://www.java2s.com/Code/Java/Database-SQL-JDBC/OracleJDBCDriverload.htm for Oracle DB connection details
