Object Caching in a CORBA Compliant System

Abstract:
Distributed object systems provide the key to build large scale
applications that can execute on a range of platforms.
The Common Object Request Broker Architecture (CORBA) specification from
OMG
attempts to address interoperability and heterogeneity issues that
arise in such systems. Our goal is to investigate performance issues for
distributed object systems. We claim that object caching is a must for
improved performance and scalability
in distributed object systems. However, to our
knowledge, the CORBA
specification does not address object caching. The purpose of this
paper is to serve as a data point in a discussion of issues related to
caching in CORBA by describing the design and implementation
of Flex, a scalable and flexible distributed object caching
system. Flex is built on top of Fresco
that uses the CORBA object model.
Fresco runs on the UNIX operating system and our implementation of
Flex exploits the features of object technology, Fresco and UNIX.
This system allows us to quantify the performance improvements for
object invocations that are made possible by caching.
Keywords: Object caching, flexible sharing, open systems, CORBA, UNIX.
