Abstract

This method relates to the generation of manipulation requests of an initialization and administration database of a server cluster comprising several nodes interconnected between each other by at least one data transmission network. It comprises steps of generating from a logical distribution of the nodes of the cluster, from a geographical distribution and from a hardware definition of the nodes of the cluster at least one set of profiles of the nodes and of the data transmission network; defining an addressing policy of the nodes of the cluster; allocating from the set of profiles and according to the addressing policy, at least one address to each node of the server cluster and generating a set of parameters of the cluster; and generating from the set of parameters of the cluster and of the addresses of its nodes, at least one file of manipulation requests of the database.
