spring+hibernate+atomikos 分布式事务管理

网上有很多的atomikos的分布式事务管理的配置，但是大多数都是同一类型的数据库，并没有跨数据库类型的配置。使用的数据库是Oracle和mysql。

配置文件代码如下：

<bean id="propertyConfigurer" class="*.*.*.DBConfigurer"><property name="order" value="1" /><property name="ignoreUnresolvablePlaceholders" value="true" />     <property name="location" value="WEB-INF/DBconfig.properties"/> </bean><bean id="mysqlDataSource" class="com.atomikos.jdbc.AtomikosDataSourceBean"

 分布式事务在连接Oracle数据时，可能会报错，错误信息如下：

javax.transaction.xa.XAException 
at oracle.jdbc.xa.OracleXAResource.recover(OracleXAResource.java:526) 
at com.ibm.ws.rsadapter.spi.WSRdbXaResourceImpl.recover(WSRdbXaResourceImpl.java:1038)

 可以在Oracle数据库中执行sql语句：

1.grant select on sys.dba_pending_transactions to  username;   
2.grant select on sys.pending_trans$ to username;   
3.grant select on sys.dba_2pc_pending to username;   
4.grant execute on sys.dbms_system to username;
