Method and management system for configuring an information system
First Claim
1. A method for changing a configuration of a dynamic information system, the method comprising:
- providing components for the dynamic information system;
providing component-specific error susceptibility data on the individual components, wherein the error susceptibility data indicates how tolerant or immune the components are with respect to errors of other components;
providing a given system configuration for the dynamic information system, the system configuration determining the components supposed to be used;
determining error susceptibility information for the dynamic information system in the given system configuration as a function of the component-specific error susceptibility data;
evaluating the error susceptibility information with reference to given evaluation criteria; and
automatically configuring the dynamic information system in the given system configuration if the error susceptibility information satisfies the given evaluation criteria.

Abstract
According to the method for configuring an information system (1), components (2) are provided for the information system (1) and component-specific error susceptibility data (3) on the individual components (2). For a given system configuration (5), error susceptibility information (7) is determined for the information system (1) in this given system configuration (5) as a function of the component-specific error susceptibility data (3). The error susceptibility information (7) is evaluated with reference to given evaluation criteria (8). In a subsequent step, the information system (1) is configured in the given system configuration (5) if the error susceptibility information (7) satisfies the given evaluation criteria (8). By means of the method, it is achieved that only system configurations are accepted that satisfy requirements specified by the evaluation criteria (8) with respect to the reliability of the information system (1).
