Hi All,

Long after I am posting new topic.

After getting succeeded with hibernate search in an application, I need to enhance search to multi-node environment. (currently 4 nodes).

I am interested with shared index approach.(Not Master-Slave approach).

Can Anyone suggest me the configuration changes to be done to achieve this?

My current hibernate.cfg.xml:

<?xml version='1.0' encoding='utf-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">



<hibernate-configuration>

Please let me the configuration changes......


Thanks in Advance,

shared index is only reliable when both Hibernate Search indexes are on the same machine, as to properly share an index it has to be stored on a non-network-shared directory (real local filesystem).
For multi nodes you need Master-Slave.

BTW from your configuration files I guess you're using fairly old versions of Hibernate Search?

Also this is the wrong forum, please use the Hibernate Search forum.
