Hi, I am new using xwiki. I would like to use lucene plug-in to extract textual area from pdf, wrod, html files. The plug-in work well but I could not find how to extract text from indexed files. I know that during indexation "lucene" read file by extracting text. Are there some person who can help. Thant you in advance Youcef National Institute of Informatics-Japan

Interesting.. I had not thought too much about the portability of the solution I used to other Databases. It would be interesting to test this in a real environment and see if something needs to be changed. It's not necessary easy to prefix tables, since it's hibernate creating the database queries. However any changes would only be in the XWikiHibernateStore class since all database access is done there. Ludovic Sam Taha wrote:

Hi Ludovic, Thanks for the reply. That is a lot of dbs running on one server, very interesting to see mysql scale this well. I am not sure if setCatalog would work the same with Postgres and Oracle. Last I check on Postgres a call to setCatalog created a different db connection (socket level stuff).

You can get the multi database stuff to work with postregres and oracle but you would instead need to qualify your table names with the corresponding namespace. Postgres has an explicit namespace feature while Oracle's is more tied to the owner of the class. This would work the same with mysql also for the most part.

Hi,

There is some information here on how to setup virtual wikis with xwiki

http://www.xwiki.com/xwiki/bin/view/Doc/HowToSetupVirtualWikis

This currently works with mysql and hasn't been tested with other DBs.. It relies on the setCatalog() function of JDBC so it should work with most DBs..

Using setCatalog does not need a separate connection pool for each DB even on mysql. The switch of database happens on the same connection. It works perfectly fine and we are running this with 4400 databases on xwiki.com
