Conference on Very Large Data Bases. DISTRIBUTED TRANSACTION MANAGEMENT IN JASMIN

In this paper, we describe the architecture of JASMIN, a functionally distributed database machine which uses replicated software modules (DM. RM, IS) to achieve high degrees of throughput. We discuss some issues in distributing data and metadata in JASMIN. We describe our distributed multiversion validation technique along with the two phase commit protocol which we use to achieve concurrency control and crash recovery for data and metadata. The scheme also solves the version consistency problem in the multiprocessor environment. 1. INTRODUaION JASMIN is an experimental database machine intended for research in large database, high volume applications. It is designed as a functionally distributed database machine, in the spirit of DBC iBAN781. SABRE [GAR831, and SPIRIT [KAM791. A common goal of these projects is to achieve hig
