Title: **David J. Wisler: Innovator in Fault-Tolerant Database Systems**
Introduction
David J. Wisler, based in Tigard, Oregon, is an accomplished inventor known for his significant contributions to fault-tolerant clustered database technology. With two patents to his name, Wisler's work has been instrumental in enhancing the reliability and efficiency of transaction processing systems.
Latest Patents
Wisler's most notable patents include:
1. **Hybrid method for flushing transaction state in a fault-tolerant clustered database.** This patent introduces a Registration Protocol designed for normal operations in transaction processing. In case of an error, the system seamlessly reverts to a Full Broadcast protocol, which allows for improved performance by reducing the number of messages exchanged among CPUs. The phases of this protocol, including Begin, DPCheck, PhaseFlush, and Phase (lock release), are aligned with the Full Broadcast Protocol to enable a smooth transition whenever an error is detected.
2. **Method for handling node failures and reloads in a fault-tolerant clustered database supporting transaction registration and fault-in logic.** This patent reveals a modified transaction registration protocol that is centralized, requiring processes to send requests to a Broadcast Owner CPU. If the Broadcast Owner fails to respond, the system alternatively reverts to a Full Broadcast transaction protocol, ensuring that outstanding registration requests are completed by distributing transactions across all CPUs in the system.
Career Highlights
David J. Wisler has forged a distinguished career at Hewlett-Packard Development Company, L.P., where he applies his expertise in the field of database systems to pioneer innovative solutions. His work focuses on ensuring system resilience and reliability, essential attributes for modern computing environments.
