Migration fom Lucene to Solr in a high load production system

prim — Mon, 16 Feb 2015 15:28:39 GMT

We are trying to migrate our Alfresco Enterprise 4.1.6 system from Lucene to Solr indexing. I've created a clone of the production system that uses the same hardware and made a full-index (Lucene) to ensure that there are no hidden problems, it has taken 84 hours with no problems and everything seem

I've done it, I've an open case (00319019) since 12 feb, but have no answer, only a rapid and banal response (so the ticket has "a good time response"), Alfresco support doesn't seem be the best support.

Is this forum only for community users, not for Enterprise?, excuse me.

Thank you

Typically Enterprise users should use the official Alfresco Support for similar problems.
Anyway questions about the Enterprise version are also welcome here

I think that probably the best option for this migration could be configuring a cluster where against an Alfresco instance Solr is indexing and against the other instance Alfresco will be available for users (using Lucene).

When the indexing process is finished you can change the search subsystem to Solr and open the related instance, previously dedicated to Solr, to users.

Probably Alfresco can help you giving a limited Cluster license dedicated to perform this migration, please try to mention this idea to the Alfresco Support

Hope this helps.

Thank you very much, PierGiorgio, I'll try your suggestion with Alfresco support.

Maybe we meet in this forum in the near future, after leaving the Enterprise world.

Bye

The time taken to index is too long. I agree with the suggestion to cluster alfresco, but there is something else going on which is why I suggested you contact support.

For a start you don't say what sort of "objects" you are indexing. That may be significant. As may the number of docs to index.

sort of "objects" we are indexing:

30% pdf readable, average 50 Kb
40% txt, doc, xls, average 900 Kb
10% images, average 2,000 KB
20% pdf non readable, average 3,210 Kb
