(v22) Manually Install OpenJDK 11

Manually Install OpenJDK 11

Composer 5.8 and later versions require Java 11.0.5. All supported Zoomdata versions and earlier versions of Composer 5 use Java 8.

To manually install OpenJDK 11:

1. Stop all Composer components (if any are running) before you install OpenJDK 11. See Stop Composer Microservices.

2. Run the following command on the installation machine.

   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 Composer Microservices.

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.
