Thanks. I'm still finding it difficult to move from unicore to multicore. What I understood so far is that we've to put a solr.xml file in $solr.home and this is the config file loaded first, if this is not available then solr looks for solrconfig.xml under coreX directory withing multicore directory. Am I right? Earlier I was using a file name solr....@tomcat.home/conf/catalina/localhost to specify $solr.home directory. If I remove that and put solr.xml under $solr.home and start tomcat accessing to solr from borwser gives me error saying path not set for core. Can someone help me fixing this. Do I need to remove the solr.xml file from @Tomcat.home/conf/catalina/localhost/ and keep the solr.xml under $solr.home. As per my requirement I want to be able to register new cores on-the-fly and start posting new docs to the newly registered core simultaneously with other existing cores.
Thank you very much.
