Re: Two Solr Webapps, one folder for the index data?

[patrick o'leary]

JVM properties restrict you to a single implementation within a jvm. For instance if you want multiple instances of solr running with the same schema, with different data dir's in the one app server. You'll have to have several copies of solrconfig and schema.xml. By using context environment, I can have multiple contexts like pjaol:~/tmp/locallucene/solr/tomcat-conf pjaol$ more solr.xml <Context docBase="/Users/pjaol/tmp/locallucene/solr/solr.war" debug="0" crossContext="true" allowLinking="true">    <Environment name="solr/home" type="java.lang.String" value="/Users/pjaol/tmp/locallucene/solr" override="true" />    <Environment name="solr/data/dir" type="java.lang.String" value="/Users/pjaol/tmp/locallucene/solr/partitions/data" override="true"/> </Context> pjaol:~/tmp/locallucene/solr/tomcat-conf pjaol$ more solr1.xml <Context docBase="/Users/pjaol/tmp/locallucene/solr/solr.war" debug="0" crossContext="true" allowLinking="true" >    <Environment name="solr/home" type="java.lang.String" value="/Users/pjaol/tmp/locallucene/solr" override="true" />    <Environment name="solr/data/dir" type="java.lang.String" value="/Users/pjaol/tmp/locallucene/solr/partitions/data1" override="true"/> </Context> Changing just the solr/data/dir for each instance. And in my solrconfig.xml  <dataDir>${env/solr/data/dir:./solr/data}</dataDir> It certainly makes development & operations easier.

How can I configure that each Solr webapp shall store the data in the folders I assigned at  <Environment value="individualSolrFolder">, where already the Solr scheme etc. resides (so that it get stored at individualSolrFolder/data/index)?

And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat. - Albert Einstein <btn_in_20x15.gif> View Patrick O Leary's profile -- Patrick O'Leary You see, wire telegraph is a kind of a very, very long cat.
