Patent ID: 8819695

Claim:
A computer network, comprising: an application landscape comprising a plurality of at least one of software and hardware components and at least one sequence of processes which can run in the application landscape; and a central control unit comprising a central control mechanism and a repository, wherein the central control unit is operable executable by at least one processor to control the application landscape and the repository includes at least one memory device, and wherein the central control mechanism comprises an activation mechanism stored on the at least memory device as instructions executable by the at least one processor operable to: check in the sequence of processes for activation in the application landscape, comprising: requesting from the repository a specification of the sequence of processes; distributing the sequence of processes in the application landscape based on the specification; activating at least one process comprised in the sequence of processes in the application landscape; up confirmation of activation of each of the at least one processes, taking over control of the at least one process of the activated sequence of processes in the application landscape; and wherein checking in the sequence of processes for activation in the application landscape protects processes of the sequence of process against access by other sequences of processes thereby locking the processes of the sequence of processes in a known state; and check out the sequence of processes by deleting the specification of the sequence of processes from the repository when the sequence of processes is no longer in use in the application landscape.
