In chapter Getting Started, you learned the basic concepts of Frank development. Simple Frank configs were presented that output a fixed message and inserted some records into a database. A H2 database was chosen because this type of database is easy to deploy. However in a production environment, a better-performing database like Oracle is often used.

A Frank config often has to operate differently during different phases of its life cycle. For example, during development a H2 database is often best while during production some other database is needed. A Frank config may also be fine-tuned differently for different production sites. This fine-tuning is typically done by system administrators who know the deployment environment and have permission to modify the systems involved. If you are a system administrator yourself, please read chapter Administrator Manual. That chapter explains how to deploy Franks on different application servers and helps you ask the right questions to Frank developers.

This section explains to Frank developers how properties allow a Frank config to be fine-tuned. Properties are just name/value pairs. You may know properties from other applications like Windows batch files or UNIX shell scripts. You encounter them in phrases like name=value, set name=value, export name=value or -Dname="value" when Java programs are being called.

This section first clarifies what properties are with a short tutorial (subsection Setting and Referencing Properties). Then, properties are linked to characteristics of your deployment environment (subsection Deployment Environment Characteristics). Then more details are given about setting properties (subsection How Properties Are Set). Finally, it is explained how properties influence the services offered by the Frank!Framework (subsection Frank!Framework Properties).
