spring+hibernate+atomikos 分布式事务管理
- - 企业架构 - ITeye博客网上有很多的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. . .
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:

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;
