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>



<session-factory>



<!-- JDBC connection pool (use the built-in) -->

<property name="connection.pool_size">1</property>



<!-- SQL dialect -->

<property name="dialect">

org.hibernate.dialect.PostgreSQLDialect

</property>



<!-- Enable Hibernate's automatic session context management -->

<property name="current_session_context_class">jta</property>





<!-- Enable the second-level cache -->

<!-- Provider is JBoss Cache -->

<!--<property name="cache.provider_class">org.jboss.hibernate.jbc.cacheprovider.JndiBoundTreeCacheProvider</property>-->



<property name="hibernate.cache.jndi">

JndiBoundTreeCacheInstance

</property>



<!-- Transaction factory that supports JTA -->

<property name="transaction.factory_class">

org.hibernate.transaction.JTATransactionFactory

</property>



<!-- enable caching of entities and collections -->

<property name="cache.use_second_level_cache">true</property>



<!-- enable caching of query results -->

<property name="cache.use_query_cache">true</property>



<property name="cache.region.jbc2.query.localonly">

true

</property>



<!-- JBoss Cache configuration file name -->

<property

name="cache.provider_configuration_file_resource_path">

jboss-cache.xml

</property>



<!-- To use JBoss Cache 2 as your Second Level Cache implementation -->

<property name="cache.region.factory_class">

org.hibernate.cache.jbc2.MultiplexedJBossCacheRegionFactory

</property>



<!-- Use query cache too -->

<property name="cache.use_query_cache">true</property>



<!-- JBoss Transactions Manager lookup class -->

<property name="transaction.manager_lookup_class">

org.hibernate.transaction.TransactionManagerLookup

</property>



<!-- Echo all executed SQL to stdout -->

<property name="show_sql">true</property>

<event type="post-update">
<listener
class="org.hibernate.search.event.FullTextIndexEventListener"/>
</event>
<event type="post-insert">
<listener
class="org.hibernate.search.event.FullTextIndexEventListener"/>
</event>
<event type="post-delete">
<listener
class="org.hibernate.search.event.FullTextIndexEventListener"/>
</event>




</session-factory>



</hibernate-configuration>



My current persistence.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/ ... ce_1_0.xsd"
version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">


<persistence-unit name="db1">
<jta-data-source>java:xab2</jta-data-source>
<properties>
<property name="hibernate.ejb.cfgfile"
value="/META-INF/hibernate.cfg.xml" />
<property name="jboss.entity.manager.jndi.name"
value="persistence-units/apptivodb2" />
<property name="hibernate.ejb.event.post-insert"
value="org.hibernate.search.event.FullTextIndexEventListener"/>
<property name="hibernate.ejb.event.post-update"
value="org.hibernate.search.event.FullTextIndexEventListener"/>
<property name="hibernate.ejb.event.post-delete"
value="org.hibernate.search.event.FullTextIndexEventListener"/>
<property name="hibernate.search.default.indexBase" value="/home/skuppusamy/Hibernate/Indexes"/>

</properties>
</persistence-unit>

</persistence>

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


Thanks in Advance,
Sorna.K

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.
