DB2 EEE architecture can improve the performance of decision support and online transaction processing systems.
DB 2EEE体系结构可以提高决策支持和联机事务处理系统的性能。
Unless you cannot avoid processing the incoming messages and database update in a single unit of work, consider using local transaction for performance reasons.
除非您不能避免在单个工作单元中处理收到的消息和数据库升级，否则因为性能的原因要考虑用局部事务处理。
This means queries are more AD hoc and not subject to the same performance testing and tuning found in transaction processing systems.
这意味着这些查询更多情况下是临时性的，事务处理系统中的性能测试和调优方法对于它们并不适合。
In this section, you will learn the performance results (as measured with DB2 9) when using an internal online transaction processing (OLTP) workload.
在这一节中，您将了解到使用内部在线事务处理(OLTP)工作负载时的性能结果(用DB 29进行评测)。
For example, if your database is used for transaction processing and heavy decision-support (DSS) queries, you can be sure that a non-scheduled DSS query will trash your transaction performance.
例如，如果您的数据库用于事务处理和繁重的决策支持(DSS)查询，则可以确定非预定的DSS查询将牺牲您的事务性能。
The past year and a half have seen a lot of DB2 for LUW activity on the standard TPC-C benchmark, the benchmark commonly used to measure performance in the on line transaction processing environment.
在过去一年半的时间里，在标准TPC - c基准方面有很多DB 2for LUW活动，这个基准常用于测试在线事务处理环境中的性能。
The middleware development team provided additional performance metrics to isolate the elapsed time for host communication, message parsing, and the middleware elapsed time for transaction processing.
中间件开发团队提供另外的性能度量，将用于主机通信、消息分析的耗用时间与用于事务处理的中间件耗用时间隔离开来。
The experimental results show that the performance optimization on ISTX can greatly improve distributed transaction processing performance under the precondition of guaranteeing reliability.
实验数据表明，对ISTX的性能优化能在保证分布事务可靠性的前提下，较大幅度地提高了分布事务处理的性能。
And this performance boost may be critical to meet the demands of Internet commerce and online transaction processing applications in the future.
这种性能提高对满足未来因特网商务和联机交易处理应用的需求，可能是至关紧要的。
For example, if your application is oriented toward online transaction processing (OLTP), slow performance will quickly result in users wanting to abandon the system.
例如，如果你的程序是面向在线事务处理(OLTP)的，操作太慢很快就会导致用户产生放弃系统的念头。
