Hi there,
I'm kinda newbie with Ignition and now trying to update our installed Ignition OpenJDK and Azul Zulu Java to answer vulnerabilities found from tenable.
Is there anyone ever know or ever done this ?
Could you please share any documentation or guidance for this ?
I've tried to search and googling using any keywords related to openJDK, Jre, Azul Zulu, Ignition but still get no luck ;(
Thanks
Upgrade Ignition and you will get the latest JRE that Ignition supports. If that isn't sufficient, you can install your own version and point Ignition to use it instead. But then you may be on your own, support-wise.
Updating Ignition to the latest patch release is by far the easiest method, and the one that's explicitly supported.
The other best option would be to replace the compressed runtimes contained in the gateway install directory. If you do that, our internal machinery will automatically update all your clients and designers to use that version.
Hi @PGriffith ,
Many thanks for your answer 
I tried to replace the compressed runtimes or even just the binaries but ignition services cannot be started.
What I did just stop Ignition services, download from this one, extract it, then replace whole "jre-win" folder from this dir "C:\Program Files\Inductive Automation\Ignition\lib\runtime\jre-win" and re-start the services but no luck.
Any idea what's wrong ?
Thanks
thanks for your answer @pturmel
I tried to use manual approach but still no luck 
You should contact support and let them look over your shoulder.
I think the recommended approach is just to make sure whatever version of Java you want to use is installed or otherwise available on the Gateway or Client and then point the corresponding config file towards that version of Java. Not to try to replace the existing runtime files.
On the Gateway it's in ignition.conf. On clients it's each individual launcher config.
