Distributed token manager with transactional properties

摘要

A system and method for controlling access to data in a distributed computer system. Distributed Token Manager (DTM) is a system-level service that coordinates read/write access of data objects (tokens) in a multi-process and multi-threaded environment. The DTM may support a transactional model such that write operations to a data object performed by a client process or thread can be either committed or rolled back.
