Solve Pentaho Server Login Issues After Java JDK Change from Oracle to Amazon Corretto

Solve Pentaho Server Login Issues After Java JDK Change from Oracle to Amazon Corretto

As data scientists and software engineers, we often encounter unexpected issues when we transition from one technology to another. Today, we will address a common problem that happens when you shift your Java JDK from Oracle to Amazon Corretto: Pentaho Server login problems.

What is Pentaho Server?

Pentaho Server is a comprehensive tool for data integration and business analytics. It provides robust data integration solutions, reporting, data mining, and enables users to create complex reports and dashboards with ease. However, it can be finicky when it comes to compatibility.

What is Amazon Corretto?

Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK). It comes with long-term support that includes performance enhancements and security fixes.

Issue: Pentaho Server Login Problems After JDK Change

The transition from Oracle’s Java Development Kit (JDK) to Amazon Corretto can cause issues with Pentaho Server login. This occurs due to differences in security configurations and libraries between these JDKs.

How to Resolve Pentaho Server Login Issues after JDK transition

Step 1: Verify Your JDK Change

First, confirm that your system is now running Amazon Corretto instead of Oracle JDK. You can do this by running the command java -version in your terminal. This will display the version of Java currently in use.

Step 2: Update Pentaho Configuration Files

After verifying the JDK change, you need to update the configuration files of Pentaho.

• Go to the Pentaho directory and locate the start-pentaho script file.
• Open the script and find the JAVA_HOME environment variable.
• Update the JAVA_HOME path to point to Amazon Corretto’s JDK.

Step 3: Update Cryptography Extension (JCE) Policy Files

One reason for login issues could be the outdated JCE policy files. Amazon Corretto comes with unlimited JCE policy by default, so you can remove any limits that were set for Oracle JDK.

• Go to the directory <JAVA_HOME>/lib/security.
• Remove or rename the existing local_policy.jar and US_export_policy.jar files.
• Restart the Pentaho server.

Step 4: Update JDBC Drivers

The JDBC drivers compatible with Oracle JDK may not work with Amazon Corretto.

• Replace the existing Oracle JDBC driver ojdbc8.jar in the <PENTAHO_HOME>/tomcat/lib directory with the latest version compatible with Amazon Corretto.

Step 5: Test the Setup

After all these changes, restart the Pentaho server and test the setup by trying to login. If the login is successful, you have resolved the issue.

If you still encounter issues, I recommend turning on debug logging for the Pentaho server to get more detailed information about the problem.

Conclusion

Transitioning from Oracle JDK to Amazon Corretto can cause login issues with Pentaho Server due to differences in security configurations, libraries, and JDBC drivers. By verifying the JDK change, updating Pentaho configuration files, JCE policy files, and JDBC drivers, you can resolve these issues and enjoy the benefits of Amazon Corretto’s robust, long-term support.

Remember, every transition comes with its set of challenges, but with a systematic approach, these hurdles can be easily overcome.
