Powerful thin client and distributed COBOL application processing

isCOBOL delivers a choice of deployment architectures without complex implementation requirements. isCOBOL programs can run locally or be distributed from a server with isCOBOL Server, simplifying distribution steps and improving time-to-market for key applications. With isCOBOL Server, applications are easily distributed to take full advantage of today’s multi-threaded processing capabilities on a variety of platforms including UNIX, Linux and Windows.

·	Delivers 100% portability by supporting any platform that runs the Java Virtual Machine
·	Eliminates the need to use a different debugger for every deployment platform; written 100% in Java
·	Eliminates the need to maintain separate user interface code for different deployment platforms
·	Offers bi-directional processing -- clients can start programs on the server and vice-versa
·	Takes advantage of today's multi-threaded, multi-core technology
·	Delivers advanced thin client and distributed processing functionality at a good value because these features are included in the isCOBOL Runtime Environment

Since isCOBOL APS is Java based, developers leverage the same GUI, regardless if the client is Windows, UNIX, Mac, handheld, etc. The user interface and all of its program functionality developed in isCOBOL APS will work the same whether the application is deployed locally or distributed across a network -- simplifying development and maintenance.

isCOBOL Server provides a thin client that can be automatically downloaded and run as a standalone Java program. isCOBOL Server runs the application on the server machine with just the user interface running on the client. When running with a thin client, the user interface is identical with what is seen when running locally. In other words, the thin client user interface supports every window and graphical control type, style and property, as well as all text-based elements. There are no differences in the user interface when running locally verses thin client and developers do not need to “program to” or “design for” isCOBOL Server software's thin client capabilities. Once a user interface is working as desired in local mode it can then be deployed in thin client mode with complete confidence that there will be no differences across platforms.

isCOBOL Server is multi-threaded, utilizing true processing threads, not emulated threads. With isCOBOL Server each program runs in a separate thread, not a separate process on the server; COBOL programs can start multiple threads and multi-task. This means that it consumes far less resources on the server and has a much faster startup response time for the end-user, conserving system memory and saving valuable CPU cycles. In addition, isCOBOL is bidirectional, so server applications can call programs on a client and client programs can call programs on the server.

isCOBOL Server provides high value both by conserving valuable system and network resources and by including thin client and distributed processing capabilities into the base runtime environment.

isCOBOL Server makes the deployment process smoother because an application is loaded only on the server. Nothing is needed on the client side, except a Java Runtime Environment (JRE) and the isCOBOL thin client Java library. isCOBOL Server accept each connection, creates a separate thread for the user session, and runs the COBOL application projecting just the user interface onto the client display.
