Can some one please answer this. Is there a way of creating/adding a core and starting it without having to reload Solr ?
Re: Load cores without restarting/reloading Solr
Hi Peter We are using the packaged Ubuntu Server (10.04 LTS) versions of Tomcat6 and Solr1.4 and running a single instance of Solr with multiple cores.

Re: Load cores without restarting/reloading Solr
Hi Andrew, the whole tomcat shouldn't fail on restart if only one core fails. We are using the setup described here: http://wiki.apache.org/solr/SolrTomcat With the help of several different Tomcat Context xml files (under conf/Catalina/localhost/) the cores should be independent webapps: A different data directory (+config) and even a different solr version is possible. Or are you using the same setup? Regards, Peter. > Hi > > Sorry, it wasn't very clear was it? [?] > > Yes, I use a 'template' core that isn't used and create a copy of this on > the command line.

Re: Load cores without restarting/reloading Solr
Hi Sorry, it wasn't very clear was it? [?] Yes, I use a 'template' core that isn't used and create a copy of this on the command line. I then edit the newcore/conf/solrconfig.xml and set the data path, add data-import sections etc and then I edit the solr.home/solr.xml and add the core name & directory to that. I then go to the Tomcat manager/html and reload Solr. The problem I get is that if I have broken something in the new core Solr (correctly) doesn't reload and the other cores aren't then working. I don't need replication just yet but I will be looking into that eventually.

Re: Load cores without restarting/reloading Solr
Hi Andrew, I didn't correctly understand what you are trying to do with 'copying'? Just use one core as a template or use it to replicate data? You can reload only one application via: http://localhost/manager/html/reload?path=/yourapp (if you do this often you need to increase the PermGen space) You can replicate a core: http://wiki.apache.org/solr/SolrReplication Regards, Peter. > Hi > > We have a few cores set up for separate sites and one of these is in use > constantly.
