ABSTRACT:
A method for a program-package change in a multicomputer system (MRS) and a computer (PR1) for the multicomputer system (MRS) are disclosed. During the program-package change, the interruption of the processes being controlled by the multicomputer system (MRS) is to be kept as short as possible. In addition, for reasons of security, fallback on operation of the multicomputer system (MRS) with the replaced, old program package is to be possible. According to the invention, each computer (PR1, . . . , PRN, SR) of the multicomputer system (MRS) has in its main memory (RAM1) an area (PPN) in which the new program package is stored before the actual replacement procedure begins. During the program-package change, each of the computers (PR1, . . . , PRN, SR) is loaded with the new program package from its main memory (RAM1).
