Supported Java Development Kits (JDK)¶

The installers of the Denodo Platform and the Solution Manager, for Windows and for Linux, include the Java Development Kit (JDK) - Eclipse Temurin version 17 LTS - HotSpot, which is the OpenJDK distribution created by the Adoptium Working Group. This group promotes and supports high-quality, TCK certified runtimes and associated technology for use across the Java ecosystem.

If you are installing the Denodo Platform or the Solution Manger on Windows or Linux, we recommend using the installer for this operating system, which already includes this JDK.

If you are installing the Denodo Platform or the Solution Manger on another operating system, download a Java Development Kit (JDK) for this operating system (it has to be a Java Development Kit, not a Java Runtime Environment). These are the Java Development Kits (JDK) supported to run the Denodo Platform and the Denodo Solution Manager:

• Eclipse Temurin version 17 LTS - HotSpot provided by the Adoptium Working Group. This is the version included in the Denodo Platform.

If you need to upgrade the JDK included in the Denodo Platform or the Solution Manager, do this:

1. Follow the steps of the Knowledge Base Article: How to change the JVM used by the Denodo Platform

2. Rename the file <PATH TO THE NEW JDK>/lib/security/cacerts to cacerts.backup.

3. Copy the file <DENODO_HOME>/jre/lib/security/cacerts to <PATH TO THE NEW JDK>/lib/security/cacerts. The “cacerts” file contains the trusted certificate authority (CA) certificates; you need to copy it to the new JDK in case you added certificates to this file.

4. Compare the file <DENODO_HOME>/jre/conf/security/java.security with <PATH TO THE NEW JDK>/jre/conf/security/java.security. If there are differences, check if these difference are due to changes that you did in this file in the JDK included in the Denodo Platform.
