Subject Re: Configuring multiple SOLR apps to play nice with MBeans / JMX
Date Tue, 23 Mar 2010 10:44:42 GMT
Hi Constantijn,

I'm not too sure about the JMX monitoring side of things but having looked
at the Solr's MultiCore <http://wiki.apache.org/solr/CoreAdmin>
feature it seems really simple to create multiple solr cores that could all
be configured to point
to one MBean server.

When creating a core you can specify name like solr1, solr2:
http://localhost:8983/solr/admin/cores?action=CREATE&name=solr_01&instanceDir=/etc/solr/multicore/core2&config=solrconfig.xml&schema=schema.xml&dataDir=data

This is made possible due to the fact that each core can have it's own
solrconfig.xml
See example/multicore/ in your solr distribution.

Hope this helps.

Regards
Charl Mert
