Hello,
I am running SOLR 4.10.0 on Tomcat 8. The solr.xml file in .../apache-tomcat-8.0.15_solr_8983/conf/Catalina/localhost looks like this: <?xml version="1.0" encoding="utf-8"?> <Context docBase="/archives/solr/example/solr/solr.war" debug="0" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/archives/solr/example/solr" override="true"/> </Context> My SOLR instance contains four cores, including one whose instanceDir and dataDir have the following values: instanceDir:/archives/solr/example/solr/indexapdf0/ dataDir:/archives/indexpdf0/data/ Strangely enough, every time I restart Tomcat, this core's data, [and only this core's data,] get deleted, which is pretty annoying. How can I prevent it? Many thanks. Philippe
