We had an openjdk8 installed in our system now. How should I install OpenHAB on my system. Is their any documents which will give an information on installations in ARM processors? Or Is it possible to cross compile OpenHAB for ARM processors from my PC?
We were able to download the package and install it into our board file system.
According to OpenHAB tutorials, first OpenHAB start will work as dashboard. Unfortunately we were working on Headless device, We needs to work on OpenHAB through command line only, is it possible for OpenHAB to be run on headless device?
Thanks for your support so far. Now we needs to find a way to work on OpenHAB through command line process.
Able to run OpenHAB successfully. Tested with Network binding and it works fine as shown in Tutorial.Might be working on ZIgbee devices next week.
As discussed in this forum openjdk is really slow, it takes around 3.30 minutes for OpenHAB to launch.
Comparatively Zulu JDK8 launches OpenHAB in 45 50 seconds.
OpenHAB crashes while running in Zulu JDK11.
There are few things which are different between Java 11 and 8. Most importantly in new version there are some more restrictive rules for loading some classes which causes warnings and sometimes failures. Differences between Zulu and OpenJDK are some, yet Zulu is based on OpenJDK. Zulu as a product base has additional optimizations, Azul Systems also advertises it can do even more by caching generated code so subsequent restarts are even faster.
I been working recently on Yocto build with OH3 and Java 11 and I got it through, yet due to own reasons I had to change directory layout a bit. I have “persistent” data (which I push away from device anyway) and user config moved to different partition while “standard” openhab settings are delivered by filesystem image and rolled out when necessary.
