A computer system is described for representing and enforcing configuration rules that can be used to create and define a configuration or hardware definition for the computer system. The computer system represents configuration rules that define a configuration of a high end mainframe, such as an OS2200 system, in a file external to a configuration program with which a user may interact to manage the configuration of the mainframe system, and to enforce the configuration rules as a user is attempting to modify a configuration of a computer system. The configuration rules may be specified in, for example, an extensible markup language (XML) file format rather than in the source code of the executable program. The external configuration file may conform to a scripting language that allows a developer to embed validation operations for the configuration data specified in the XML file.

Real-time management of a configuration of a computer system

Streaming media servers are used to provide data streams of streaming media data to network devices across a communications network. In order to allow the servers to scale its processing as the number of data streams increases, these servers use a delay timer determination module for determining when a given CPU is to transfer its streaming media data corresponding to its group of data streams, a CPU wake up module for initiating an acceleration process for each CPU upon receipt of a signal from the delay timer determination module, and a plurality of CPU processing modules for transferring streaming media data corresponding to its group of data streams. The delay timer determination module uses a stagger and interval parameter where these parameters are calculated from a set of system parameters, including a number of processors available to support data streams, CPU, a size for the smallest data buffer within all of the network devices, Mem, and the maximum bit data transfer rate, BR, supported.
