For example , it stops sql server profiler traces it was collecting , it stops executing transact - sql scripts it was running , and it stops any sub processes it has spawned during data collection 例如，它将停止正在收集的sql server事件探查器跟踪，停止执行正在运行的transact - sql脚本，同时停止在数据收集期间生成的任何子进程。
For example , a parent process can set a lock , call a child to do the work make sure only the parent can call the child in a way that it can work , and when the child returns , the parent releases the lock 例如，一个父进程可以设置一个锁，然后调用一个子进程来执行工作（确保父进程可以有效地调用子进程） ，当子进程返回时，父进程释放该锁。
This multi - layer fontal machine system completely conform to the request of unified terminal join - in , reduced burden of main machine , multichannel compatibility and easy extension under data centralization ; the communication layer with fore - born child process is easy for extending to integrate some other communication data channels 这种多层的前置机系统，符合数据大集中对统一终端接入、减轻主机负担、多通道兼容和易扩充的要求；基于tcp ip的预先派生子进程的通讯层设计容易扩充集成多种数据通道。
What s more , simple concurrent programming has been available on essentially all unix hosts since at least 1988 , which is when ksh standardized its " co - processes . " if you save the ksh source in listing 1 , below , as ex1 . ksh and then run it , you ll see a " countdown " - " ten , nine , eight , etc . " - display , then the result of the ksh subprocess : " all done . " in practice , you might use something like this for a long - running chemical calculation or database retrieval : launch the operation as a subprocess , but keep users informed about what s going on or how much time is left before completion 此外，至少自1988年以来，基本上已经在所有unix主机上实现了简单的并发编程，在1988年这一年ksh对其“协同进程（ co - process ） ”进行了标准化。如果您将下面清单1中的ksh源代码保存为ex1 . ksh ，然后运行它，您会看到“倒计时”显示： “十、九、八，等等” ，然后看到ksh子进程的结果： “ all done ” 。实际运用中，您可能会对长期运行的化学计算或数据库检索使用类似这样的操作：启动操作作为子进程，但是让用户始终知道操作的进展或完成之前还剩多少时间。
The article puts forward a solution that the fontal machine system for the problems of the data concentration , bank " s multi - channel join - in and the host " s dispose efficiency during the construction of finance eleclrolysation ; designs and realizes the fore - born child process communication layer of the fontal machine system 本论文对金融电子化建设过程中面临的数据大集中、多通道接入、银行主机处理效率等问题，提出前置机系统解决方案；设计和实现了前置机系统的预先派生子进程的通讯层。
