Subject [jira] [Commented] (KARAF-2840) Creating child container using admin service should use KARAF_OPTS
Date Fri, 21 Mar 2014 07:59:03 GMT

Achim Nierbeck commented on KARAF-2840:
---------------------------------------

thanks for the patch. 
I'm always a bit confused where the difference is between a admin:create and admin:clone.

That's why I thought that the clone command should do this. A create is supposed to work as
a unzip of the karaf.zip 
Where this configuration isn't done either. 
Or did I get this totally wrong? If so never mind my brabling ....

> When you use admin:create to create a child container, then the AdminService is used
to create the JVM process. This code does not read the KARAF_OPTS environment variable which
means the child container does not use that when started.
> But if you use the bin/start script to start the child container, then the setenv script
will read the KARAF_OPTS. 
> So that means there is a difference between using the admin commands to crate|start child
containers, vs using the bin scripts.
> This is a serious problem for Windows users on IP6 network that hits a well known issue,
where they have to set a JVM system property to work around this.
> If they do not you get network issues such as
> java.net.SocketException: Permission denied: no further information
> To fix this with Karaf you set this option
> KARAF_OPTS '-Djava.net.preferIPv4Stack=true'
> Maybe either globally in the Windows box, or in the bin/setenv.bat file.
> But the child containers do not pickup that env option when created by admin server.
> This patch fixes that.
> To see if the env option was picked up by Karaf, you can connect to the child container,
and run
> {code}
> dev:system-property | grep java.net
> {code}
