CICS是运行联机应用程序所必需的吗 [英] Is CICS is necessary to run online applications

问题描述

服务器需要CICS来处理网络上的多个客户端.不能单独由操作系统来处理此问题，我读到一篇文章说，CICS模仿了操作系统的功能，即多任务处理多个客户端请求.网络.

IBM首先引入了CICS，以解决同时为不同用户运行多个不同程序的问题，直到计算机一次运行一个程序为止.

"CICS是真实操作系统内部的一个小操作系统.它复制了常用的程序接口来管理内存，打开文件，与远程系统进行通信等.但是，CICS在相同的进程地址空间中运行了很多程序.因此没有确保两个程序不会互相干扰，但CICS可以处理成千上万的n/w用户."

Is CICS is necessary for a server to handle multiple clients over a network.Can''t operating system alone handle this,i read in an artcle saying CICS emulates the functionality of operating system interms of multitasking to handle multiple client requests over network.

And IBM had first introduced CICS to address running several different programs for different users at the same time,till that time computers ran one program at a time

"CICS was a little operating system inside the real OS. It duplicated the usual program interfaces to manage memory, open files, communicate with remote systems, etc. However, CICS ran lots of programs in the same process address space. So there is no guarantee that two programs would not interfere with each other but CICS was able to handle thousands of n/w users."

推荐答案

"主要在z/OS和z/VSE下的IBM大型机系统上运行的事务服务器"

我想如果您有IBM大型机，则可能需要CICS.我从没听说过.

"CICS (Customer Information Control System) is a transaction server that runs primarily on IBM mainframe systems under z/OS and z/VSE"

I guess if you have an IBM mainframe you may need CICS. I''d never heard of it.
