Manually Install OpenJDK

Composer v23.2 and later runs on Java 17. When you perform a straightforward upgrade to this release, Java is updated automatically.

Composer v23.1 and earlier continue to run on Java 11.

Manually install OpenJDK

1. Stop all Composer components (if any are running) before you install OpenJDK. See Stop Microservices.

2. Run the following command on the installation machine.

   For JDK 17:

   sudo mkdir -p /opt/zoomdata/jre && curl -sL https://corretto.aws/downloads/latest/amazon-corretto-17-x64-linux-jdk.tar.gz | sudo tar zx -C /opt/zoomdata/jre --strip-components=1

   For JDK 11:

   sudo mkdir -p /opt/zoomdata/jre && curl -sL https://corretto.aws/downloads/latest/amazon-corretto-11-x64-linux-jdk.tar.gz | sudo tar zx -C /opt/zoomdata/jre --strip-components=1

3. Restart all Composer components. See Start Microservices.

Note: In Windows environments, Composer installs a compatible JDK as part of the bootstrap installation. To install a system wide Java distribution, see https://www.java.com/en/download/help/windows_manual_download.html.

For information on how Composer validates the version of Java used in an environment, see How Composer Validates an Environment's Java Version.
