This paper identifies the basic functions required from a communication subsystem in order to support a distributed, reliable, reconfigurable, and replicated database processing environment. These functions include: reliable multicast, different types of remote procedure calls, inexpensive datagram services, and efficient local interprocess communication.(More)
This research presents our experimentation with several methods of providing efficient communication facilities for distributed database systems. These studies give insight into the delays incurred by applications running on distributed systems. We have implemented , compared, and analyzed five different mechanisms for local interprocess communication (two(More)
This paper identifies the basic services required from a communication subsystem to support transaction processing in a distributed, reliable, reconfigurable, and replicated database environment. These services include multicasting, remote procedure calls (RPC), inexpensive datagram services, and efficient local interprocess communication (lPC). We show the(More)
Distributed database systems need special operating system support. Support routines can be implemented inside the kernel or at the user level. Kernel-level functions, while eecient, are hard to implement. User-level implementations are easier, but suuer from poor performance and lack of security. This paper proposes a new approach to supplement or modify(More)
