Micro Focus Application Server是一种高性能的可升级的开发平台，主要用于配置由Object COBOL Developer Suite、 Net Express 或Server Express for Windows and UNIX等开发工具开发的COBOL程序。

Application Server is a set of powerful run-time facilities that enable COBOL applications to run on all leading Windows, UNIX and Linux platforms without code changes.

Overview

Micro Focus Application Server™ is a high-performance execution environment to deploy COBOL applications on all of today’s popular Windows and UNIX platforms. Micro Focus Application Server supports a variety of object formats to provide users with the flexibility to balance performance with portability. If your key requirement is performance, you may utilize native code optimization for specific hardware chips. If your key requirement is portability, then applications can be created where the object code can be built once and run on any supported platform with the confidence that the code will work exactly the same way, regardless of differences in operating systems or hardware platforms. If you wish to deploy under Microsoft .NET, then COBOL can be compiled to execute with Application Server under the .NET Framework in association with the Microsoft Common language Runtime (CLR). Micro Focus Application Server is the deployment component for Net Express®, Server Express™ and Object COBOL™ Developer Suite development products.

Delivering Applications Where Your Customers Need Them
IT organizations and software vendors alike have always wished they could create application code once and deploy it on whatever operating environment makes the most business sense. With the advent of Java and the publicity behind it, the IT industry believed the promise that "write once, run anywhere" was within its grasp. The fact is, the ability to "write once, run anywhere" is not new and has been around many years. In fact, the language that has delivered first and most consistently on this promise is not Java, but Micro Focus COBOL. Micro Focus Application Server enables COBOL application portability without additional programming. It is a set of powerful run-time facilities that enable COBOL applications to run on all leading Windows, Linux and UNIX platforms without code changes. Micro Focus Application Server includes features that simplify operating system interfaces, communications, user interface, database access and file handling.

Satisfying the Performance and Reliability Demands of the Business
The demand for increased application processing is constant. This is partially satisfied by the continued increase in processor power, but customers demand greater reliability and faster recovery when things do go wrong. Micro Focus Application Server is a collection of tools and utilities that allow you to run your COBOL applications at the highest performance level your systems provide, as well as providing the ability to quickly diagnose and recover from problems should they occur.
