Abstract
Beam dynamics applications at the Swiss Light Source (SLS) have benefitted from a
distributed computing environment in which the Common Object Request Broker Architecture
(CORBA) forms the middleware layer and access point to several different software
components.A suite of remote CORBA server objects provides the client with a convenient
and uniform interface to the CDEV (Common DEVice) controls library, the TRACY accelerator
physics package, the Oracle database, and en event logging facility. Use is made of
methods provided by the CORBA Portable Object Adaptor for accessing ORB functions,
such as object activation and object persistence, the Implementation Repository for
the automatic reactivation of servers, and the CORBA Event Service for the propagation
of controls and physics data. An account of the CORBA framework, as used by applications
in the commissioning and first operation of the SLS, is presented.
