Activate Your Programs On Demand

Integrated Language Environment (ILE) programs and service programs must be activated before they can be run; activation consists of allocating and initializing static storage for the program and runtime linking of programs to the service program exports that they reference. If you’ve programmed in ILE, you should be familiar with activation. Prior to IBM i 6.1 (and by default in 6.1), service programs were immediately activated during the call to a program that directly or indirectly used their services.
