December 2002 to January 2004 : Software Engineer:
Design and implementation a new CORBA architecture for a data acquisition real time system for MudLogging, based on the data server developed earlier.
The aim is to manage all the server-side modules in a same way.
- Design administration and diagnosis procedures
- Design CORBA interfaces using the procedures to standardize the behavior of all the servers regarding administration tasks
- Implement this interfaces in the 30 different CORBA servers, each one manage a particular type of data.
- Design a GUI to allow the users to use the procedures, diagnoses a problem and try to solve it.
- Changing ORB from Visibroker 3 to JavaIDL, and using of POA instead of BOA in all the system.
- Design and implement a solution to launch the different servers in different JVM other the different PCs used.
- Design and implements a set of tools and different clients for this server (User applications, Scripting tools, computation processes, …)
Main Points :
- Interfaces in distributive system
- CORBA, JavaIDL, System programming in Java
