Subject [jira] [Commented] (SOLR-3613) Namespace Solr's JAVA OPTIONS
Date Wed, 11 Jul 2012 19:48:34 GMT


Jan Høydahl commented on SOLR-3613:

An example I just thought about is all the Java CMSes, ECMs and other systems now integrating
Solr as their bundled search engine. They tend to integrate Solr alongside their other apps,
for small and medium installs, and advice the customers to move it to a dedicated server when
things grow big. One of these is [Escenic Content Engine|],
Solr here runs at {{/solr/}} alongside the {{/escenic/}} editors webapp, {{/escenic-admin}}
administrator webapp and {{/studio}} studio webstart webapp. In the same physical appserver/JVM
the customer (typically newspapers) deploy their newspaper webapp(s), with any number of libs,
Java-opts etc.

I think this will be a more and more common case going forward, and a big reason to keep Solr
a web-app, and making it as intuitive as possible to deploy and configure it.

> Solr being a web-app, should play nicely in a setting where users deploy it on a shared
> To this regard Solr's JAVA_OPTS should be properly name spaced, both to avoid name clashes
and for clarity when reading your appserver startup script. We currently do that with most:
{{solr.solr.home,, solr.abortOnConfigurationError, solr.directoryFactory, solr.clustering.enabled,
solr.velocity.enabled etc}}, but for some opts we fail to do so.
> Before release of 4.0 we should make sure to clean this up.
