Master/Slave switch on teh fly. Replication
Hello.
Is it possible to switch master/slave on the fly without restarting the
server?

No, you can reload the whole core at any time, without interruption.
Even with a new solrconfig.xml.
You can even add a new core at runtime, fill it with data and switch
cores afterwards.
See http://wiki.apache.org/solr/CoreAdmin for details.

only load on startup and i cannot change master to slave and slave to master
without restarting the servlet-container ?!?!?!

What's the use-case? Presumably you have different configs...
I'm actually not sure if you can do a reload
see: http://wiki.apache.org/solr/CoreAdmin#RELOAD
without a core, but you could try.
Best
