【摘要】某电信公司运营支撑平台的计费系统使用串行批价，随着业务量的增加，批价花费时间过长。采用并行批价的机制以提高处理效率，减少批价时间。为了避开多进程动态优先级的管理，减少父子进程通信的开销，充分利用SQL Server提供的优化策略，使用多进程静态调度策略，并利用OSQL工具和批处理实现任务的并行执行。由于每条话单信息需要多于一次的更新操作，使用锁机制会降低并行效率，所以采用以空间来换取时间的方式，提高并行执行效率。%With the increase in business volume, the billing module which calculates bills serially takes a longer time. The time is too long to wait. Calculating bills in parallel can improve the efficiency and reduce the time. In order to avoid the dynamic priority management of multi-process, reduce spending of communication between parent-process and his son-processes, take advantage of the optimization strategies provided by SQL Server, the static scheduling strategies of multi-process are concerned, and OSQL tools and batch help to achieve parallel execution of tasks. Since every CDR record needs to be updated more than one time, and using a lock mechanism will reduce the parallel efficiency, sacrificing space for time is a way to improve the efficiency of parallel execution.
