Hi guys!
I have got JBoss 4.2.2, DROOLS BRMS 4.0.4 and Oracle 10g XE as RDBMS.
I defined an Oracle XA Datasource Drools Repository as follows:
/<xa-datasource>
<jndi-name>jdbc_XA/Drools_Rep</jndi-name>
<track-connection-by-tx/>
<isSameRM-override-value>false</isSameRM-override-value>
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
<xa-datasource-property
name="URL">jdbc:oracle:thin:@//localhost:1521/xe</xa-datasource-property>
<xa-datasource-property name="User">...</xa-datasource-property>
<xa-datasource-property name="Password">...</xa-datasource-property>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
<!--
<prepared-statement-cache-size>0</prepared-statement-cache-size> -->
<!-- <blocking-timeout-millis>100</blocking-timeout-millis> -->
<!-- <min-pool-size>2</min-pool-size> -->
<!-- <max-pool-size>30</max-pool-size> -->/
/
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>/
/ <no-tx-separate-pools/>
<metadata>
<type-mapping>Oracle9i</type-mapping>
</metadata>
<use-java-context>false</use-java-context>
</xa-datasource>/
This repository is managed with JackRabbit.
So i defined the "repository.xml" telling jackrabbit that I want
to persist the rules into the Oracle XA Datasource I previously defined:
/ <PersistenceManager
class="org.apache.jackrabbit.core.persistence.db.JNDIDatabasePersistenceManager">
<param name="dataSourceLocation" value="jdbc_XA/Drools_Rep"/>
<param name="schema" value="oracle"/>
<param name="schemaObjectPrefix" value="${wsp.name
<http://wsp.name>}_"/>
<param name="externalBLOBs" value="false" />
</PersistenceManager>/
The problem comes out each time I reload the rulebase from
the BRMS....each time the RuleAgent wants to load
a rulebase (from the XA datasource ) the following exception is
thrown and the execution stops for 4-5 seconds:

*As u can see, each time jboss tries to access the drools DS, it finds*
*a previous connection opened, so Jboss HAS TO close it by itself!*
As far as U know, Is there any way to tell JackRabbit that he has to
close connections?
Hibernate has something like that so I expect that JackRabbit does the
same...
I already tried to redefine the XA datasource setting some tags
related to the
"connection\connection pools" but it did not work...that's why I am
quite sure
the problem has to be focused on jackrabbit!
Thank you anyway.
If u want you can answer me to [EMAIL PROTECTED]
<mailto:[EMAIL PROTECTED]> as well.
Bye.
Massi
