OH 2.2 stopped working after updating Java

Setup, Configuration and Use Installation

Hi,

due to hints in these threads I updated my OH 2.2 java to an actual Version.
I used way of updating java

pi@OpenHAB:~ $ java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) Client VM (build 25.151-b12, mixed mode)

Unfortunately OH stopped working after this…

Is there anybody out there who could give me a hint?

What does the last startup log for openHAB say, you can find this at the very end of:

sudo journalctl -u openhab2 -b

fyi, there’s also a 8u152 available now.

There seems to be an karaf issue…

Since you’re using the snapshot version, with apt, try stopping the service and then stopping any additional instance: (If the following doesn’t work, what did the output of the status command give below?)

sudo systemctl stop openhab2
sudo openhab-cli stop
sudo openhab-cli status
sudo systemctl start openhab2
6

this happens…

sudo /bin/systemctl status openhab2.service

   Loaded: loaded (/usr/lib/systemd/system/openhab2.service; enabled; vendor preset: enabled)

As in, what is the output of:

sudo openhab-cli status

There should also now be new, different information in journalctl. Providing that the above command couldn’t find another running instance.

8

here we go…

pi@OpenHAB:~ $ sudo openhab-cli status
A systemd service configuration exists...
Use 'sudo /bin/systemctl status openhab2.service' to find the status of an openHAB service
openHAB is not running.
9

To summarise what we’ve been doing, and what I expect has happened. There may have been an issue in updating JAVA while openHAB was running, from the first journalctl post it was clear that it couldn’t start because there was another stuck instance. This is clearly no-longer the case but there’s still a failure somewhere.

Does

sudo openhab-cli start --debug

work for starting an instance in the shell?

10

here is the answer

sudo openhab-cli start --debug
A systemd service configuration exists...
Use 'sudo /bin/systemctl start openhab2.service' to start an openHAB service
Launching an instance in this terminal..
Launching the openHAB runtime...
There is a Root instance already running with name main and pid 476
11

It would be safer to restart your device, there’s clearly a stuck process.

However if you can’t restart (and only if), you can kill that instance by running the following and then openHAB should be able to start.

sudo kill -9 476
sudo systemctl start openhab2
