Atomikos Forum

Hey guys,

I'm trying to integrate Atomikos with an existing (maven) project for a couple of days but had no luck yet...

I'm using:
 - Tomcat 6.0
 - 4 PostgreSQL DBs (we need to do 2PC on these DBS)
 - Hibernate 3.3.2.GA
 - Spring 3.0.0.RELEASE
 - Atomikos 3.6.2

Here is my config:

In Tomcat's context.xml, I've added:

----------------------------------
<Transaction
  factory="com.atomikos.icatch.jta.UserTransactionFactory" />
----------------------------------

In Tomcat's server.xml, I've added the 4 DBs within the <GlobalNamingResources> tag, each DB declaration looks like:

----------------------------------
<Resource name="jdbc/xxxDataSource"
    auth="Container"
    type="com.atomikos.jdbc.AtomikosDataSourceBean"
    factory="com.atomikos.tomcat.BeanFactory"
    uniqueResourceName="jdbc/xxxDataSource"
    xaDataSourceClassName="org.postgresql.xa.PGXADataSource"
    xaProperties.serverName="localhost"
    xaProperties.portNumber="5432"
    xaProperties.databaseName="db-xxx"
    xaProperties.user="postgres"
    xaProperties.password="postgres"
    maxPoolSize="100"
    minPoolSize="50" />
----------------------------------

I also added the DBs to my webapp's context.xml, with something like this for each of them:

----------------------------------
<ResourceLink name="jdbc/xxxDataSource"
      global="jdbc/xxxDataSource"
      type="com.atomikos.jdbc.AtomikosDataSourceBean"/>
----------------------------------

and to my webapp's web.xml (also for each of the DBs):

----------------------------------
  <resource-ref>
    <description>XXX Data Source</description>
    <res-ref-name>jdbc/xxxDataSource</res-ref-name>
    <res-type>
      com.atomikos.jdbc.AtomikosDataSourceBean
    </res-type>
    <res-auth>Container</res-auth>
  </resource-ref>
----------------------------------

In my webapp's Spring file, I have (still for each of the DBs):

----------------------------------
<jee:jndi-lookup id="xxxDataSource"
                jndi-name="jdbc/xxxDataSource"/>
----------------------------------

The Spring file also contains the transaction manager related beans:

----------------------------------
<!-- Construct Atomikos UserTransactionManager,
    needed to configure Spring -->
<bean id="atomikosTransactionManager"
      class="com.atomikos.icatch.jta.UserTransactionManager"
      init-method="init" destroy-method="close">
  <!-- when close is called, should we force
      transactions to terminate or not? -->
  <property name="forceShutdown" value="false" />
</bean>

<!-- Also use Atomikos UserTransactionImp,
    needed to configure Spring -->
<bean id="atomikosUserTransaction"
      class="com.atomikos.icatch.jta.UserTransactionImp">
  <property name="transactionTimeout" value="300" />
</bean>

<bean id="transactionManager"
      class="org.springframework.transaction.jta.JtaTransactionManager">
  <property name="transactionManager"
            ref="atomikosTransactionManager" />
  <property name="userTransaction"
            ref="atomikosUserTransaction" />
</bean>

<!-- enable the configuration of transactional
    behavior based on annotations -->
<tx:annotation-driven
    transaction-manager="transactionManager" />
----------------------------------

and a session factory and a template for each DB:

----------------------------------
<bean id="xxxSessionFactory"
      class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
  <qualifier value="xxx"/>
  <property name="dataSource" ref="xxxDataSource"/>
  <property name="packagesToScan">
    <list>
      <value>abc.def.xxx</value>
      <value>abc.ghi.xxx</value>
    </list>
  </property>
  <property name="hibernateProperties">
    <props>
      <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
      <prop key="hibernate.jdbc.batch_size">20</prop>
      <prop key="hibernate.hbm2ddl.auto">validate</prop>
      <prop key="hibernate.show_sql">false</prop>
      <prop key="hibernate.transaction.factory_class">
        com.atomikos.icatch.jta.hibernate3.AtomikosJTATransactionFactory
      </prop>
      <prop key="hibernate.transaction.manager_lookup_class">
        com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup
      </prop>
    </props>
  </property>
</bean>

<bean id="xxxHibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
    <property name="sessionFactory" ref="xxxSessionFactory" />
  </bean>
----------------------------------

I'm getting exceptions at webapp startup:

I can't find what I'm doing wrong, so any idea, suggestion, link... would be greatly appreciated :)

Thanks,

Hi,

This looks like an incompatible log file from a previous release.

You can try with deleting the .log file that contains the recovered transactions.

If in production mode then FIRST do this:

-put back the previous release
-start the transaction core and let it recover
-make sure all transaction requests finish

HTH

Hey Guy, thanks for the answer!

I'm not sure what you mean by previous release: previous release of ...Atomikos?

The thing is I don't have any log file. I'm trying to setup Atomikos but didn't get it to work yet.

My jta.properties file is located in $TOMCAT_HOME/lib and contains:

----------------------
com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory
com.atomikos.icatch.log_base_dir=../work
com.atomikos.icatch.output_dir=../work
com.atomikos.icatch.console_log_level=DEBUG
----------------------

and the $TOMCAT_HOME/work directory doesn't contain any log file...

Hi,

OK in that case this looks like a class loader problem. I have no ready-made answer right now, but if you have a budget for developer access (support) then I can arrange a one-on-one remote support session. Let me know.

Thanks
