  1. Aida; Accelerator Integrated Data Access Middleware Continued Episode 3; Verdi’s Revenge M. Claussen, R. MacKenzie, R. Sass, H. Shoaee, K. Underwood, G. White EPICS Collaboration Meeting - Paul Scherrer Institut

  2. CDEV CORBA compliant ORB Channel Access CDEV CORBA compliant ORB Channel Access In the Last Episode… The Un-classic not-so-thin client with a JVM & XML CORBA compliant ORB Non-IOC Application Cloud CDEV CORBA compliant ORB Channel Access IOC Applications EPICS Collaboration Meeting - Paul Scherrer Institut

  3. The Current Episode Support get/set/monitor any data from/to any source EPICS Collaboration Meeting - Paul Scherrer Institut

  4. Supporting Ideas • Name and schema mapping • Data location discovered at runtime. • CORBA middleware & services • Server resilience (auto reconfigure on server down) • API and OPI • Language and OS independent • Collections, Aliases, Range Names EPICS Collaboration Meeting - Paul Scherrer Institut

  5. Name and Schema Mapping Each name.attribute{.attribute}0+ maps to a database query EPICS Collaboration Meeting - Paul Scherrer Institut

  6. Salient Features • Given a name.attribute, AIDA finds the source and appropriate query • Uses its own name services • Data Location and Query persist/cached (not rediscovered) • C++ & Java Bindings • Can code as API or OPI EPICS Collaboration Meeting - Paul Scherrer Institut

  7. Simple OO Example Class QUAD { private AIDA d; QUAD( string name ) { d = new AIDA(name); } float get( string attribute ) { return d.get(‘’B_desired’’); } float[2][6] getTwiss() { org.omg.CORBA.Any t= d.getAny(‘’Model.Twiss’’); ... } } QUAD fred(‘’quad:pr04144’’); float bfieldwanted = fred.get(‘’B_desired’’); float twiss[2][6] = fred.getTwiss(); EPICS Collaboration Meeting - Paul Scherrer Institut

  8. Where We’re At • Have a complete set of requirements. • Accessed EPICS & old SLC data via Corba. • Java Corba -> JDBC -> Oracle • C++ Corba -> ODBC -> Oracle • Sample Name & attribute databases with query mapping to get data • Have a Java Orb on VMS • Testing Notify Service for Monitors • Ready to implement something real EPICS Collaboration Meeting - Paul Scherrer Institut
