duplicated karaf instance issue
Hi JB,
I found there is duplicated karaf instance issue in linux ENV. I used karaf
2.3.3.
It will create karaf instance for each time executing command "start".
for instance, execute the command "start" twice and I can see 2 instance.
And the command "stop" only can stop one instance.
Log as below.
[gravity@cfnyps2d bin]$ start
[gravity@cfnyps2d bin]$ start
[gravity@cfnyps2d bin]$ ps -aux | grep karaf

my question: Do you know how to avoid duplicated instance when multi-execute
command "start"?

Re: duplicated karaf instance issue
Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.
Hi,
Actually, it's possible to run multiple instance on the same machine
(you just have to change the port number).
In new Karaf version, the bin/status script allows you to check if an
instance is already running (using the start port number).
So, before using bin/start, you can check with bin/status.
On the other hand, you can use system command (ps -ef|grep -i karaf,
etc) to check if the Karaf JVM is there.
Regards
JB
