560 results about "Parallel running" patented technology

Parallel running is a strategy for system implementation where a new system slowly assumes the roles of the older system while both systems operate simultaneously. This conversion takes place as the technology of the old system is outdated so a new system is needed to be installed to replace the old one. After a period of time, when the system is proved to be working correctly, the old system will be removed completely and users will depend solely on the new system. The phrase parallel running can refer to the process of changing a fragment of business information technology operation to a new system or to the technique applied by the human resources departments in which the existing staff stay on board during the transition to a new staff.

Highly scalable and highly available cluster system management scheme

A cluster system is treated as a set of resource groups, each resource group including an highly available application and the resources upon which it depends. A resource group may have between 2 and M data processing systems, where M is small relative to the cluster size N of the total cluster. Configuration and status information for the resource group is fully replicated only on those data processing systems which are members of the resource group. A configuration object/database record for the resource group has an associated owner list identifying the data processing systems which are members of the resource group and which may therefore manage the application. A data processing system may belong to more than one resource group, however, and configuration and status information for the data processing system is replicated to each data processing system which could be affected by failure of the subject data processing system-that is, any data processing system which belongs to at least one resource group also containing the subject data processing system. The partial replication scheme of the present invention allows resource groups to run in parallel, reduces the cost of data replication and access, is highly scalable and applicable to very large clusters, and provides better performance after a catastrophe such as a network partition.

Garment-concealable jewelry case having parallel-running compartments and integrated jewelry trays for storing and organizing jewelry

A garment-concealable jewelry case having a front opening with a front cover panel portion that can be either moved or configured to reveal a plurality of parallel-running isolated storage compartments each having an interior storage space which is accessible through a front opening revealed when the front cover panel is removed or reconfigured. Through the front opening of each storage compartment, one or more necklaces, pendants, bracelets or other strands of jewelry can be securely hung on a pair of jewelry support posts adapted for spatial separation on the back wall portion of the storage compartment in order to accommodate the length of jewelry strands being supported. The bottom portion of each parallel-running isolated compartment has a stationary front panel portion which, cooperating with the other wall portions of the storage compartment, provides a five sided stationary storage tray accessible through the opening of the respective storage compartment and within which articles of jewelry such as rings, watches, earrings and/or tie tacks can be placed for organization and storage. The front cover panel has a tray cover panel integrated therewith, which closes off each jewelry storage compartment when the front cover panel is positioned over the access opening formed in the case housing. When the front cover panel is closed, the jewelry support posts contact the rear surface of the front cover panel to prevent supported articles of jewelry from falling off and tossing about within the storage compartment during usage, including travel.

Method and system for performing SW upgrade in a real-time system

A new method is disclosed, for upgrading the software in a real-time distributed software system comprising several processes running in parallell. The method involves a preparatory procedure in which the new software is installed. Then, the software is activated, the components ordered to save configuration data and transaction data in a database, whereupon the components are stopped. When the preparatory procedure is completed, a restart procedure is invoked. This involves selecting start level (full upgrade involving all components, or a partial upgrade concerning just one or a few components). The modules concerned are started from the new software version. On each start level a number of start phases are defined. These are sequential steps performed during the restart operation. Each module subscribes to a number of these phases. Some of the phases are defined as synchronisation points, here called service levels, which all modules have to arrive at before the process is allowed to commence. During this process, each module is given the responsibility of converting any configuration data or transaction data belonging to it, if needed. The conversion is done by reading the old data from the database mentioned above and converting said data to the format required by the new software.
