How to Connect MySQL and Oracle Databases with JMeter

This article explains how to configure Apache JMeter to connect to MySQL and Oracle databases using JDBC.

MySQL connection : Download the MySQL JDBC driver (e.g., mysql-connector-java-5.1.28.jar ) that matches your MySQL version, place the JAR in JMeter/lib/ext , and restart JMeter. Add a Thread Group, then add a JDBC Connection Configuration element with the appropriate URL, username, password, and driver class. Create a JDBC Request to execute SQL, add a View Results Tree listener, run the test and verify the results. JDBC requests support parameters and assertions.

Oracle connection : Ensure the correct SID is defined in tnsnames.ora (example configuration shown below) and copy ojdbc14.jar to JMeter/lib/ext , then restart JMeter. ems_uat = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.16.33.192)(PORT = 1608)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SID = emsuat) ) ) Add a Thread Group, then add a JDBC Connection Configuration for Oracle using the URL jdbc:oracle:thin:@10.16.33.192:1608:emsuat . Create a JDBC Request, run it, and view the results with a View Results Tree . Common errors include missing driver JARs or incorrect database URLs; verify the configuration if problems arise.
