Container virtual machine

The objective of the Container Virtual Machine (CVM) consists to dynamically adapt the services associated to the applications oriented CCM components. The CVM prototype is running in OpenCCM, an application servers open source implementation of the CORBA Component Model (CCM) specification defined by the Object Management Group (OMG). It is executed on the standard JVM of Sun that does not offer any adaptation's mechanism.

The CVM solution introduces the concept of entry point into CCM applications. These entry points are used to configure the associations between the various components and services by indicating to OpenCCM, which are the modifications to do.

Thus, the CVM allows the instantaneous adaptation of the system services during the execution, reducing the costs of reconfiguration. It allows an administrator to specify and deploy dynamically system properties (like monitoring, tracing or QoS), not planned initially.
