Development of a CORBA Toolkit and its Evaluation

Trials to develop a CORBA toolkit have been made at DESY and KEK. This toolkit provides basic APIs for general-purpose data exchange. There are two aims of the trials. The first one is to make it easier to convert the existing CORBA applications of older versions (Digital’s @aGlance) to those with the new CORBA environment (Object Broker). Since the toolkit includes a complete emulation of the @aGlance functionalities, re-use of the existing sources becomes possible. The second aim is to evaluate the availability of CORBA over different control systems. In order to inspect the availability, the toolkit was introduced into three different control systems at DESY and KEK. As a result, communication availability has been demonstrated over three different platforms. In addition, when an application is developed with the APIs of the present toolkit, it can communicate with any of the three different control systems. Thus, the present work encourages the sharing of application software between DESY and KEK.
