Distributed Computing with BEA WebLogic Server
Dean Jacobs · 2003
This paper surveys distributed computing techniques used in the implementation of BEA WebLogic Server. It discusses how application servers provide a distributed transactional infrastruc- ture that extends outward from backend data- bases. The basic treatment of data is character- ized in terms of four types of clustered services that differ in the way they manage state in memory and on disk. This paper also discusses how application servers support loosely-coupled clients, both at the transport level and at the higher level of server-to-server Web Services. Finally, this paper speculates about the development of a new application server persistence layer and its use in widely-distributed computing.
