Alfresco 4.2.c migrate from lucene to solr..

[bilelkaabar]

I am using Alfresco 4.2.c and want to migrate from Lucene to Solr.

I have followed every step in alfresco documentation. After starting alfresco, the log keep showing this message :

 INFO  [solr.tracker.CoreTracker] [SolrTrackingPool-alfresco2] .. updating

Here is a portion of my log :

It keeps showing that like forever

Does anyone has any idea what can be the problem and how to fix it?

Thanks

You should share the full log, as origin of the problem can be hidden in the part you did not share.

Well, I have gone through the log and there is nothg else but these lines... Now Solr has finished indexing (after 7 hours).

When we used to work with Lucene, it used to take about 2 hours to perform a full reindex, 2 hours was an issue for Alfresco users as the server is not available for these period when a reindex is recquired.

This was the reason why we switched to Solr, but it took us 7 hours to have our indexes back (too much) 

Is there a way to enhance solr performance?
