realizing the leasing concept in corba-based applications
Although in recent years the concept of leasing has become more and more popular in the field of distributed object-oriented systems, it has not yet been incorporated in the current specification of the widespread CORBA standard.In this paper, we present an approach to the problem of realizing the leasing concept in a CORBA environment. We examine different leasing variants, such as exclusive or shared leasing, leasing with or without prolongation, etc., describe different ways to implement these variants in CORBA, e.g., based on a specialized object adapter, a runtime library or framework, or a CORBA service, and we discuss the advantages and disadvantages of each approach.Furthermore, we show how existing CORBAservices such as Naming, Trading, and Property Service can benefit from leasing facilities. Finally, we briefly present some architectural details of our own implementation of an exemplary CORBA Leasing Service.
