java 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">
       <property name="order" value="1" />
       <property name="ignoreUnresolvablePlaceholders" value="true" />

    </bean>

        <!-- 管理 Connection 被占用的时间 -->
        <!-- 如果不设置这个值,Atomikos使用默认的300秒(即5分钟),那么在处理大批量数据读取的时候,一旦超过5分钟,就会抛出类似 Resultset is close 的错误 -->

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) 
at com.ibm.ws.Transaction.JTA.XARminst.recover(XARminst.java:138) 
at com.ibm.ws.Transaction.JTA.XARecoveryData.recover(XARecoveryData.java:687) 
at com.ibm.ws.Transaction.JTA.PartnerLogTable.recover(PartnerLogTable.java:524) 
at com.ibm.ws.Transaction.JTA.RecoveryManager.resync(RecoveryManager.java:1859) 
at com.ibm.ws.Transaction.JTA.RecoveryManager.run(RecoveryManager.java:2580) 
at java.lang.Thread.run(Thread.java:810)

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;
