When a CA Gen generated application requires changes, the application developer modifies the appropriate diagrams and regenerates the affected application components. For relatively small changes, it is not necessary nor is it desirable to regenerate the entire application. However, it is not always obvious which components the change affects. CA Gen Intelligent Regeneration tool automates the process of determining which components need regeneration.
You can still perform repeat generation of application components by expanding load modules and making selections in the normal Construction panels. In some cases, when it is clear which components need regeneration, you prefer this approach. However, if you are not sure what changed, or if you are uncertain which application components need regeneration, the Intelligent Regeneration tools can make the analysis for you.
You can mix the two methods of regeneration with no ill effects. When you upload changes to the Host Encyclopedia, the model is updated in a manner that supports subsequent identification of components requiring regeneration.
Intelligent Regeneration lets you regenerate only those parts of an application system that is affected by recent changes to the model. Intelligent Regeneration makes maintenance of existing systems quicker and easier to implement because CA Gen tracks the changes to the model and performs selected generation only of changed components.
In addition to automatic determination and application component regeneration, Intelligent Regeneration lets you examine the impact of proposed changes before making the changes. You can also review the impact of changes made before regenerating the affected components.
