With the recent progress in distributed information processing technologies as well as the growing movement toward open systems, the demand for open distributed systems that can provide mission-critical corporate services has been increasing.
In response to these requirements, the Service Providers Integrated Requirements for Information Technology (SPIRIT) group was organized as a subordinate group of the Network Management Forum (NMF).
NMF promotes network management standardization and SPIRIT is intended to assist in the development of generaol-purpose computer procurement specifications for distributed processing.
Hitachi, which has been continually developing products conforming to the SPIRIT specifications, provides an implementation of the SPIRIT specifications on OpenTP1, an online transaction processing (OLTP) monitor based on UNIX.*
This implementation also guarantees both portability of application programs (APs) and interoperability among systems.
This paper describes the SPIRIT specifications, including an implementation of these specifications as well as a discussion of design concepts and features.
