Abstract: The invention relates to a system and a method for automatic installation and maintenance of hardware and/or software in the system nodes (SK) of a distributed computer system, in particular in a distributed automation system, comprising a system installation and/or system maintenance tool (WZ), wherein the system installation and/or system maintenance tool (WZ) can be activated from a single arbitrary access in the distributed system. The system installation and/or system maintenance tool (WZ) selects a software package and/or a functional component, and automatically executes the maintenance steps of the selected software package and/or of the selected functional component as regards the distribution, installation and/or configuration of the software package and/or of the selected functional component in a defined sequence on the system nodes (SK) of the distributed system.

Abstract: The invention relates to a system and to a method for automatically providing system software which is filed in software packets, for system nodes which are arranged in a distributed network, in particular in a distributed automatic system. The inventive system comprises at least one system diagnosis tool which analyses the current state of the system of the distributed network and combines the current state of the data in system status data which is guided to at least one knowledge-based planning tool. Said knowledge-based planning tool produces a system plan for a novel system version, based on control and data, from the system status data and a planning data base, generating installation data for an automatic installation and configuration of the system configuration based on the produced system plan for the system nodes of the distributed network, and guides the installation data to at least one installation and configuration tool, provided in the system nodes.

Abstract: A system and a method are disclosed for automatic installation and maintenance of hardware and/or software in the system nodes of a distributed computer system, in particular in a distributed automation system, comprising a system installation and/or system maintenance tool that can be activated from every system node of the distributed system. The system installation and/or system maintenance tool (WZ) selects a software package and/or a functional component, and automatically executes the maintenance steps of the selected software package and/or of the selected functional component as regards the distribution, installation and/or configuration of the software package and/or of the selected functional component in a defined sequence on the system nodes (SK) of the distributed system.

Abstract: A distributed computer system is disclosed which contains at least two physical computers and at least two services installed in the system. The computers function as servers for at least one of the services. To make the system redundant, at least one of the physical computers, in addition to containing the server functionality of a first service, also contains a virtual machine having the server functionality of a second service. A method is also disclosed for implementing redundant server functionalities in a distributed computer system.

Abstract: The invention relates to a system and to a method for automatically creating, installing and configuring extensions of functionalities in the system nodes of a distributed network, in particular in a distributed automatic system, provided with at least one system diagnosis tool which analyses the current state of the system of the distributed network and combines in system status data which is guided to at least one knowledge-based planning tool. The knowledge-based planning tool creates installation data for the novel system extensions which are based on control and data from the system status data and a planning data base and guides said installation data, respectively, to at least one installation and configuration tool, which is provided in the system nodes.
