Changing Gateway Java Version

You can change the Java version that the Gateway Service is using by editing the Ignition configuration ignition.conf file. The Configure>Status page of the Gateway shows the current Java version you are running.

Here is how you can change the current Java version:

  1. Go to Program Files > Inductive automation > Ignition > data and find the ignition.conf file.

  2. Open the ignition.conf file and scroll down to the wrapper Java Properties section.

  3. Change
    wrapper.java.command=C:/Program Files/Java64/bin/java.exe
    to
    wrapper.java.command=C:/Program Files/Java/jre8/bin/java.exe

  4. Save the ignition.conf file.

  5. Launch the Gateway Control Utility (GCU) and click Restart to start the Service again.

After Ignition is restarted, you can verify that the Java version is updated by going back to the Configure>Status page to see the Java Version you are now running.
