Running Azul Platform Prime

Once you performed all installation steps, you can start running your Java applications with Azul Platform Prime as follows:

  1. Verify the Java version:

    /opt/zing/zing-<jdk-version>/bin/java -version

    Sample output for Java 8:

    java version "1.8.0-zing_19.07.0.0" Zing Runtime Environment for Java Applications (build 1.8.0-zing_19.07.0.0-b3) Zing 64-Bit Tiered VM (build 1.8.0-zing_19.07.0.0-b4-product-linux-X86_64, mixed mode)

    You may want to set the JAVA_HOME environment variable to point to the Azul Platform Prime installation directory, e.g. $ export JAVA_HOME=/opt/zing/zing-<jdk-version>.
