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}_"/>
<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:
*12:29:36,170 INFO [CachedConnectionManager] Closing a connection for you.

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 m.magistri(a)reply.it as well.
Bye.

Why use an XA datasource? It would not seem that the BRMS would be
involved in global transactions with multiple participants. Perhaps you
could try a local tx datasource and see if you still get the warning.
The exception is logged at INFO; typically it is not a problem, since
the app server will close the connection. I seem to remember there is
even a setting on the datasource to suppress the warning message. Not
sure why execution would stop for 4-5 seconds though.
