Hi,
I have a problem using multiple xaresources on jboss-4.2.2. The scenario is the following one:
I have an EJB3 application which needs to connect to 3 different databases (i.e. 3 different database schemas) and exxecute update operations on the schemas within ine transaction. The database is Oracle 10 and I use JPA to iteract with the db entities (with hibernate 3.2, which is provided with jboss). For example one session bean has to do the following operations:
1. Insert or Update some tables in the first schema
2. Insert or Update some tables in the second schema
3. Insert or update some tables in the third schema
For each schema connection i declare a datasource file inside the jboss deploy directory:
scema1-ds.xml
schema2-ds.xml
schema3-ds.xml
I use xa-datasource, so for example the schema1-ds.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<xa-datasource>
<jndi-name>schema1DS</jndi-name>
<track-connection-by-tx>true</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:oracle10</xa-datasource-property>
<xa-datasource-property name="User">schema1user</xa-datasource-property>
<xa-datasource-property name="Password">schema1password</xa-datasource-property>
<exception-sorter-class-name>
org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter
</exception-sorter-class-name>
<no-tx-separate-pools/>
<type-mapping>Oracle9i</type-mapping>
</xa-datasource>
the other schemas have the same file structure.
Now, when I try to execute the session bean, it performs the operations but when the session bean ends and JBOSS has to end the transaction I have the following exception:

Instead, if I declare the datasources as local-xa-resources as for example:
|
| <datasources>
| <local-tx-datasource>
| <jndi-name>schema1DS</jndi-name> <connection-url>jdbc:oracle:thin:@localhost:1521:oracle10</connection-url>
| <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
| <user-name>scema1username</user-name>
| <password>schema1password</password> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
| <metadata>
| <type-mapping>Oracle9i</type-mapping>
| </metadata>
| </local-tx-datasource>
| </datasources>
|
|
everything works, i.e. the transaction is successfully ended (committed), but I have a warning message:
2008-10-03 09:34:18,937 WARN [com.arjuna.ats.jta.logging.loggerI18N] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.multipleWarning] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.multipleWarning] Multiple last resources have been added to the current transaction. This is transactionally unsafe and should not be relied upon. Current resource is org.jboss.resource.connectionmanager.TxConnectionManager$LocalXAResource at e9e162
Is this the proper solution? Do I have to care about this warning? is there I way to avoid it and to use the xa-resources instead of local-xa-resources?
