Local and global commit scopes tailored to work units

摘要

A computer system or network tailors scopes of commit processing by using local work unit identifiers and more global logical unit of work identifiers. The local work unit identifiers are used to identify the scope of commit processing within each execution environment, and the logical unit of work identifiers are used to identify related work units of different execution environments. The related work units are coupled to each other by a protected conversation between the execution environments.
