A Middleware Architecture for Scalable, QoS-Aware, and Self-Organizing Global Services [chapter]

Franz J. Hauck, Erich Meier, Ulrich Becker, Martin Geier, Uwe Rastofer, Martin Steckermeier
2000 Lecture Notes in Computer Science  
A globally distributed service can be completely encapsulated into a single distributed object which contains not only all necessary components for scalability (e.g., caches and replicas) but also the  ...  Globally distributed services need more than location transparency. An implementation of such a service has to scale to millions of users from all over the world.  ...  In a CORBA environment, our service will consist of multiple CORBA objects implementing replicas, caches and partial services.  ...

A server side caching scheme for CORBA

Atul Kumar, Pankaj Jalote, Deepak Gupta
2004 24th International Conference on Distributed Computing Systems, 2004. Proceedings.  
Our model provides strong consistency by using a dependency graph that specifies dependence information among method invocations of an object. We have implemented this scheme as a service in CORBA.  ...  We propose a caching scheme for saving the results of invocations of read methods at server side.  ...  CASCADE [15] is a distributed caching service for CORBA objects. CASCADE supports caching of active objects (both data and code).  ...

Accessing and distributing EMBL data using CORBA (common object request broker architecture)

L Wang, P Rodriguez-Tomé, N Redaschi, P McNeil, A Robinson, P Lijnzaad
2000 Genome Biology  
The techniques of developing loaders and 'live object caching' with persistent objects achieve a smart live object cache where objects are created on demand.  ...  The EMBL object model is defined such that it provides a basis for specifying interfaces in interface definition language (IDL) and thus for developing the CORBA servers.  ...  A live object is an in-memory object in the live object cache. A CORBA object is a CORBA implementation object defined in IDL. Creation of a CORBA object is called instantiation.  ...
