Date Fri, 07 Sep 2012 23:37:38 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "CoreAdmin" page has been changed by HossMan:


  This can be useful when (backwards compatible) changes have been made to your solrconfig.xml
or schema.xml files (e.g. new `<field>` declarations, changed default params for a `<requestHandler>`,
etc...) and you want to start using them without stopping and restarting your whole Servlet
+ <<Anchor(LiveReload)>>
+ === Important Note About Some Configuration Changes ===
+ Starting with [[Solr4.0]], the RELOAD command is implemented in a way that results a "live"
reloads of the SolrCore, reusing the existing various objects such as the SolrIndexWriter.
As a result, some configuration options can not be changed and made active with a simple RELOAD...
+  * `IndexWriter` related settings in {{{<indexConfig>}}}
+  * {{{<dataDir>}}} location
+ See [[|SOLR-3592]] for more background.
  == RENAME ==
  Change the names used to access a core.  The example below changes the name of the core
from "core0" to "core5".
