1. A method in a data processing system for improving the responsiveness of a dedicated, application-specific host computer being sized to insure a concurrent transaction backlog during peak hour, the host computer including disks, disk control units, and files on disks controlled by the disk control units, and having measurable central processing unit (CPU) and input/output (I/O) service times, the method comprising the steps ofdefining a set of operating principles relating to the operation of host system by capturing operational and descriptive information supplied by a host system expert who acts as a mentor,transforming said set of operating principles into an executable knowledge base and storing said knowledge base in a memory of an expert system support process having memory,measuring the CPU and I/O service times of the host computer under control of said support process storing the service times in said support process memory,processing the service times to convert the service times to system state data organized into a state space of processing rates and queuing times, andapplying said executable knowledge base to said system state data to obtain host throughput-response time trade-off adjustment information so as to modify the transaction concurrency of the host computer as determined by said trade-off adjustment information.
