Περίληψη:
The concept of scheduling is relevant to many computer-engineering
areas, such as operating systems, computer networks, enterprise
platforms and applications. Scheduling at the application level (a.k.a.
Job Scheduling) is a common process in the enterprise domain, but very
few IT solutions cover all the required features. Such features include
scalability, fault-tolerance and load balancing. In this paper we
present the design and implementation of a modular job scheduling
system, developed to work in a distributed clustered environment, which
satisfies the aforementioned requirements. Its architecture and
implementation is based on the Java 2 Enterprise Edition (J2EE)
framework so that it inherently guarantees portability over different
plaforms through the use of open interfaces. A preliminary performance
evaluation of the system provides indications on its behavior under
various levels of workload.
