Hi Peter Thanks a lot for reply. Actually I need real time indexing and query at the same time.
Here told: "You can run multiple Solr instances in separate JVMs, with both having their solr.xml configured to use the same index folder." Now Q1: I'm using Tomcat now, Could you please tell me how to have separate JVMs with Tomcat? Q2:What should I set for LockType? Thanks in advanced ________________________________ From: Peter Karich <peat...@yahoo.de> To: solr-user@lucene.apache.org Sent: Tue, December 7, 2010 2:06:49 PM Subject: Re: Solr & JVM performance issue after 2 days Hi Hamid, try to avoid autowarming when indexing (see solrconfig.xml: caches->autowarm + newSearcher + maxSearcher). If you need to query and indexing at the same time, then probably you'll need one read-only core and one for writing with no autowarming configured. See: http://wiki.apache.org/solr/NearRealtimeSearchTuning Or replicate from the indexing-core to a different core with different settings.
