Subject Re: create core with separate solrconfig.xml
Date Mon, 15 Mar 2010 16:48:30 GMT
Hi Shalin,

Thank you for your reply.
I think I mixed 2 matters in my prev mail (replication and core creation).
So let me first get help for my CORES set up.
My current set up is:-
In my SOLR_HOME I have *conf*/configfiles (like schema.xml, solrconfig.xml
etc...)
I created my new core say coreA using command:-

http://localhost:8983/solr//admin/cores?action=CREATE&name=coreA&instanceDir={SOLR_HOME}&config=solrconfig.xml&schema=schema.xml&dataDir={SOLR_HOME}/core3/solr/data/

Note:- the place-holder {SOLR_HOME} ... stands for my SOLR_HOME which I have
fully substituted there.

As a result of running this query, I had a new directory coreA created in my
SOLR_HOME. But inside coreA I didnt find a new conf directory to see my
configuration files specific to my new coreA (otherwise where should i be
looking to see the schema.xml and solrconfig.xml specific to coreA). It
seems it is still referring to the common schema.xml and solrconfig.xml
inside my {SOLR_HOME}/conf.

Where do I see the solrconfig.xml and schema.xml specific to coreA??

Now only the dataDir has been created for coreA in
{SOLR_HOME}/core3/solr/data/

Thanks and Rgds,

Mark
