2. Database Testing with JMeter
• Most of the applications’ performance can be tested by triggering HTTP, FTP
or some other protocols.
• There are some cases where we want to directly test the database system
without interfering the HTTP calls.
• Apache JMeter has a built-in JDBC Request module.
• Let’s see how we can do database testing with Jmeter!
– JMeter can connect to any database and run SQL queries concurrently. In
order to do so, it’s mandatory to have necessary JDBC drivers in the lib
folder of your installation.
– Most important part of the Database performance testing is to have valid
connection strings in JDBC Connection Configuration.

3. JDBC Connection Configuration
• Add a JDBC Connection Configuration by using Add-> Config Element
menu. There are some fields that should be filled out.

4. JDBC Connection Configuration
• Variable Name: This value will be used in our JDBC Sampler. In case there is
more than one SQL connection, JDBC request will use the right DB
Connection by using this value.
• Connection Pool Configuration: Leave it as it is. These values are good
enough for a performance test. In case it’s needed, increasing or decreasing
the values is a possibility.
• Database URL: It’s obvious isn’t it?
• JDBC Driver Class: It’s different for every Database vendor
– Mysql uses com.mysql.jdbc.Driver
– Oracle uses oracle.jdbc.driver.OracleDriver
– Microsoft uses com.microsoft.sqlserver.jdbc.SQLServerDriver

5. • Username & Password: Another obvious configuration, isn’t it?
• Lastly, add a JDBC Sampler using Add->Sampler menu. Just fill out
the Variable Name property you defined in the configuration. It must be
exactly the same. Every request should be bound to a JDBC Configuration.
If it’s not, the statement will not be executed by JMeter.
