The RDi install is fairly straight-forward. But one question that users have wondered about is the one on using an existing package group or creating a new one.

The notion of a package group is of a group of products that are integrated together. If you only have one product, then you create a package group just for the one product. If you have multiple products, you can choose to install them all into the same package group so that they are integrated (all their functionality being available in one IDE).

There are additional uses of package groups even if you only have one product. You can install the same product multiple times and choose different package groups. With the same product in multiple package groups, you have some possiblities:

• when a fixpack for the product is released, you can update one of your package groups to the new fixpack and give it a try. This would not affect the other package group so there is no risk.

• you can choose to install different options in the package groups. In one, you could just have the minimum features (RSE and iProjects). This would simplify the UI (since the other features would not be available) and might have some performance gains (since the other components are not being loaded). In another, you could have RSE, iProjects, Application Diagram, Screen Designer, and RTCi client.

Note: if you install RDi into package group A and then install RDi again into package group B, your disk space usage only increases slightly (it does not put another complete copy of RDi on your machine).
