A system and method synchronizes multiple data stores and achieves data consistency in a non-transactional multiprocessing computer system. Processes are paused and later resumed according to their position in a dependency tree of the system. The data input sources of the system are in effect disabled and any data flow currently in progress in the system is flushed out the various data flow paths to the different data stores. When this process is complete, each of the multiple data stores is synchronized and the data is in a consistent state.

Achieving consistency and synchronization among multiple data stores that cooperate within a single system in the absence of transaction monitoring

Discovery/layout software configures a general purpose computer system to act as a management station using an industry standard SNMP protocol. The discovery/layout software has a discovery mechanism and a layout mechanism which, in combination, permit the discovery/layout software to provide various submaps to a display for illustrating network topology, which includes devices and device interconnections of the network. The submaps correspond to various hierarchical views of the network. Significantly, a persistence specification mechanism is provided in the discovery/layout software for specifying a submap as either transient (generated upon demand) or persistent (exists whether demanded or not). An integrating application as well as the user can identify a submap as persistent. This feature enables better interfacing of the integrating application with the station, thereby providing more information to the user. This feature further minimizes memory requirements as well as requisite processing time due to the elimination of unnecessary submaps and the elimination of processing of topology changes relative to the unnecessary submaps.

Discovery/layout software configures a general purpose computer system to act as a management station using an industry standard SNMP protocol. The discovery/layout software has a discovery mechanism and a layout mechanism which, in combination, permit the discovery/layout software to provide various submaps to a display for illustrating network topology, which includes devices and device interconnections of a network. The submaps correspond to various hierarchical views of a network. Significantly, one or more filtering systems are provided in the discovery/layout software for filtering objects to be displayed within the submaps. The filtering systems reduce clutter in the submaps, reduce memory usage and associated expense, and reduce interprocess communication (context switching) to achieve higher performance.

Discovery/layout software configures a general purpose computer system to act as a management station using the industry standard SNMP protocol. The discovery/layout software has a discovery mechanism and a layout mechanism which, in combination, permit the discovery/layout software to provide various submaps on demand to a display. The submaps are directed to various hierarchical views of the network. The discovery mechanism monitors and discovers the device configuration on the network and maintains a topology data base indicative thereof. A layout mechanism has a translator which converts the topology data from the topology data base to map data, which is maintained in a map data base. Significantly, topology data is received by the translator in a batch and, in addition, map data is transferred from he translator in a batch.
