Solr 1.4 requestHandler "update" Runtime disable/enable
Is there a possibility at the runtime to disable or enable of update handler?
I have two servers and would like to turn off the update handler on master.
Then replicate master to slave and switch slave to master.

That's an exercise left to the reader :)
Honestly, I don't think you need to. Why would you? The handler does not do anything if never called.

One Solr server does not know about the other, so you do not need to "switch" anything
on the Solr side. You simply need to design your client in such a way that it handles
the operations in correct order and timing, i.e. that it pauses all feeding until replication
is done, then feeds to the new master instead of the old.

Ok.
I can set it so:
<requestHandler name="/update" class="solr.XmlUpdateRequestHandler"
enable="${solr.enable.master:true}"/>
But how without restarting Tomcat can I change solr.enable.master from true
to false ??

I have a buffer in the application. So I do not have it off.
I have to switch automatically, without administrator intervention.
Application is switching from one location to other and solr must
automatically follow the application.

Sure.
<requestHandler name="/update" class="solr.XmlUpdateRequestHandler" enable="${solr.enable.master:true}" />
Then set Java System Property -Dsolr.enable.master=false and restart.
But I don't see why you need to disable it. You will anyway need to stop sending updates to the old master yourself. Disabling the handler like this will cause an exception if you try to call it because it will not be registered.
