An information processing system includes a runtime versioning facility which allows for managing its configuration so that modifications made during runtime are propagated and take affect without restarting the system or a portion thereof. This allows the potential for 100% uptime while upgrading such systems. This also provides a system capability to process multiple configuration versions, and to be able to process such versions even while such versions are changing during operation of the information processing systems. For example, a system such as a registry server capable of transactional configuration changes is provided which manages its configuration so that modifications made during runtime are propagated and take affect without restarting the server.

Runtime versioning of information processing systems

A registry service is described which uses a partitioned publisher assertion recording and accessing scheme. A publisher assertion regarding a relationship between entities (e.g., business or other types of entities) is encoded within a directory information tree in a memory. The publisher assertion includes publisher assertion part nodes corresponding to entity nodes in the directory information tree. The publisher assertion is complete if all publisher assertion parts corresponding to entities in the relationship are present in the directory information tree. The service may include a network including directory servers and registry servers. The publisher assertions are manipulated by authorized publishers and accessed by users using a variety of techniques, the operations of which are performed by such parties and/or are encoded upon computer-readable media.
