Just clarifying : My query was more specific to Solr. I wanted to check if there are any Solr resources that are session-specific that we need to release.
*>> I can't understand: do you use several web applications in a same >> container? >> Are you trying to close shared SolrCore when one of many users (of another >> application) logs off?* I have only one application that is built on top of Solr. I mentioned SolrCore in my mail only because that was the only object that I noticed which had a close() method. I don't intend to do a close() on SolrCore when a particular user logs out (closes his session) *> There is no 'logout'. There is no permanent state in Solr beyond the Lucene > index. There are caches, but these do not require any termination. The > Lucene API has very solid self-protection for the indexes and Solr uses the > API in the right way.* I understand Solr application does not have a logout. Please correct me if I am wrong but you seem to be stating that there is no explicit action required from our side to release any Solr resources when a user terminates his/her session of a Solr based application. If that is the case, then my query is answered. Thank you all. Regards Rahul On Sun, Aug 23, 2009 at 7:16 AM, Lance Norskog <goks...@gmail.com> wrote: > Sorry, hit 'send' too soon.
