摘　　要：为有效地保证分布式事务的ACID性质以及解决多个客户程序并发访问某一事务所造成的访问冲突,根据CORBA对象事务服务OTS(Object Transaction Service)、并发控制服务CCS(Concurrency Control Service)及其提供的相关接口,采用两步提交协议和并发控制锁机制实现。并将两者相结合实现一个账户之间的转账操作,证明其可行性。In order to effectively guarantee the ACID properties of distributed transactions and to solve the conflict caused by a number of clients access to a transaction, according to the CORBA object transaction service,concurrency control and their related interfaces, using respectively two-phase commit protocol and lock mechanism to accomplish them.At last, this paper combining the two to implement the operations of a account, and proves their feasibility.
