Abstract : The System Management experiments (four in all) exercise the environment from the perspective of the system manager. The first experiment investigates the procedures necessary to install an APSE on a raw machine or on top of an existing operating system. The second experiment addresses the issues of user account management, whereas the third investigates the maintenance aspects of supporting a running environment. The fourth System Management experiment deals with system resource management activities such as: collecting accounting information, monitoring the system workload, and reconfiguring (tuning) the operating environment for optimal performance. Following the evaluation methodology outlined in Chapter 1, each APSE will be evaluated with respect to its support of System Management activities across the evaluation dimensions of functionality, performance, user interface, and system interface. The overall intent of this group of experiments is to provide a comprehensive evaluation of an APSE's support for typical System Management activities (i.e., environment installation, user account management, environment maintenance, and system resource management). The scope for the remainder of this chapter will be to carry out all six phases of the evaluation methodology for the first and second system management experiments in the context of the VMS/ALS (Ada Language System), VMS/VAXSet, and Unix/VADS (Verdix Ada Development System) Ada environments. Additionally, the third and fourth System Management experiments will be carried out through the environment dependent steps of the evaluation methodology (i.e., Phase 1 through Phase 3).
