Upgrading the Oracle JDBC Driver Module in JBoss EAP 6: A Step-by-Step Guide

Managing dependencies and ensuring your application is running smoothly is a common task for developers. When your application is built on JBoss EAP 6 and includes Oracle JDBC drivers, you might encounter scenarios where you need to upgrade to a newer version, such as Oracle JDBC Driver version 19. In this guide, we will explore how to effectively upgrade the JDBC driver module in JBoss EAP 6, ensuring a seamless transition to the new driver version.

Understanding the Current Setup

Before diving into the upgrade process, let’s review the current setup:

Application Deployment: Your application is packaged as an EAR file and deployed in JBoss EAP 6.

JDBC Driver: The Oracle JDBC driver was originally added as a core module located in com/oracle.

Datasource Configuration: The datasource is configured in standalone.xml referring to the specific JDBC driver module:

Additionally, the Oracle JDBC driver jar is included as a Maven dependency in the pom.xml and specified in the application.xml located in the EAR's META-INF folder.

Steps to Upgrade the Oracle Driver

To successfully upgrade the JDBC driver, follow these organized steps:

1. Update the Maven Dependency

The first step in the upgrade process is to update the Oracle JDBC driver dependency in your pom.xml file. Change the version to the desired version (i.e., 19):

2. Modify the Datasource Configuration

Next, update the datasource configuration in the standalone.xml. You will need to make adjustments to the driver entry:

Note: The addition of the slot attribute points to the folder created for the new JDBC driver.

3. Create the New JDBC Driver Module

You will now create a new folder within the JBoss modules directory to store the upgraded driver files:

Path: modules/com/oracle/oracle19

Within this directory, you need to add the new JDBC driver Jar file (ojdbc8.jar) and create a new module.xml file to define the module.

4. Define the Module Configuration

The module.xml file should look like this:

5. Validation of Changes

After making the above changes:

Ensure there are no syntax errors in your XML configurations.

Restart your JBoss EAP server to apply the changes.

Monitor the server logs for any warnings or errors related to the JDBC driver during startup.

No Changes Needed in application.xml

There is good news! There is no necessity to modify application.xml since JBoss will load the datasource automatically based on the information specified in standalone.xml.

Conclusion

Upgrading the Oracle JDBC driver in JBoss EAP 6 involves updating your Maven dependency, modifying the datasource in the configuration files, and creating a new module for the upgraded driver. By following these clear and organized steps, you will leverage the latest features and improvements provided by the new version of the Oracle JDBC driver, ensuring enhanced performance and reliability for your application.
