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 ?? >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. 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. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-1-4-requestHandler-update-Runtime-disable-enable-tp2493745p2500603.html Sent from the Solr - User mailing list archive at Nabble.com.
