- Development: where the developers can have an isolated work area
- Testing: where developers don't interrupt the business/IT testers
- Production QA (AKA PQA, User Acceptance Testing, UAT): where business users can test in a clean environment
- Production: where everything always works
- WebFOCUS Report Server
- WebFOCUS Client web tier
- WebFOCUS Developer Studio
- Database adapters (which require credentials to access the data)
- Optional components (e.g., Distribution Server, ReportCaster, InfoAssist, R Stat, etc.)
I am not a proponent of using this "localhost" environment as a personal development environment which would then be promoted into the "real" corporate environment. Rarely is the developer's personal computer setup like the corporate WebFOCUS environments, meaning that promoting from one to the other is prone to error and frustration, wasting everybody's time.
The full Developer Studio product with the localhost environment costs more. Instead, you could forego the localhost features and pay a thousand dollars less.
Setting up database credentials on a personal computer could also lead to security issues.
Note: if you are using a "temporary" Report Server that runs only when Developer Studio is being used (you did not install a real WFRS), then your administration configuration file will instead be here: C:\ibi\DevStudio77\srv77\profiles\admin.cfg.
