Digital Technical Journal

This issue of the Digital Technical Journal, published in Winter 1991 (Vol. 3, No. 1), is dedicated to transaction processing (TP), databases, and fault-tolerant systems. It provides an in-depth look at Digital's distributed transaction processing architecture (DECdta), transaction processing monitors (ACMS and DECintact), and the integration of transaction management support into the VMS operating system kernel. The journal also features papers on performance evaluation methodologies using the TPC Benchmark A, techniques for preliminary sizing of TP applications, database availability strategies, and fault-tolerance verification for the VAXft 3000 system.
