3. The LANSA Environment

What is an environment?

Most operating systems support the concept of "environments" in one form or another. Basically, having different "environments" in your system means that one group of system users can work at what they are doing without being disturbed by the existence of another group of users.

The classic two environment division is development and production. Developers can work on a new version of a system in one environment while the users run the current production system in another.

Environments may be real (physical constraints) or conceptual (understood rules). For example, you might have two separate machines to separate development and production. An application is created on the development machine and then migrated to the production machine.

Alternatively, a single machine might be used on which different passwords and libraries are set up. Where only one machine is available, the production and development environments are usually separate libraries. Security is set up to prevent developers from accessing production libraries and vice versa. Once an application is complete, it is moved from a development library to a production library.

There are two methods of creating multiple environments within LANSA:

The approach you use will depend upon site requirements. The preferred way to do provide multiple environments within LANSA is by installing separate and completely independent LANSA systems
