2. CMW status 6 Feb. 2002 Outline CMW components (1 slide) Status of components and services (4 slides) Relations with supported clients (5 slides)

3. CMW status 6 Feb. 2002 CMW models and services Device/property model allows get/set/subscribe on properties of named devices. Data is transported as language-independent data objects. The core of implementation is RDA, it is Object-Oriented and is using CORBA. It is the mainstream of CMW. All CERN accelerator devices can be accessed today this way. Topic model is essentially based on JMS with some CMW- developed wrappers. A commercial product (SonicMQ) is assuring this functionality. It is currently little used. As it is standard, commercial product ideal for loosely-coupled systems, we want to promote use of it. Services provided by CMW include Device Naming Service, Database Service, CMW Device Explorer and administration facilities.

4. CMW status 6 Feb. 2002 Device/Property model RDA Stable since Oct. 2001. New release with cleanups (February) Scheduled development – Asynchronous support in server, access control (Spring 2002) Device API Current version as of Oct. 2001. Improved (final) version being prepared (February) Server Framework New Framework since October Stable. No major changes planned

5. CMW status 6 Feb. 2002 CMW – made servers PS Server Stable – will be deployed on start – up Planned improvements concern server generation SL-Equip server Recently ported to the new framework Full SL-Equip functionality supported SL-Equip devices are being defined in DB (April) Can run as GW on Linux or native on LynxOS 3.1 To be stress-tested and used for Passerelle (April) OPC server Original version as of April 2001 Has to be ported to the new server framework (Summer 2002)

6. CMW status 6 Feb. 2002 Topic model, Services JMS SonicMQ Stable Explore & promote use Naming services Stable Database Services New DB for OPC and SL-Equip definitions (April) Explorer and administration services New version for May 2002

7. CMW status 6 Feb. 2002 Other Documentation Full programming documentation available as JavaDoc and Doxygen for C++ Software User Manual available (~50 pages) but not completed yet Deployment & versioning Managed by Razor Release management not existing LynxOS3.1 in SL Being introduced slowly

8. CMW status 6 Feb. 2002 Supported clients PS application section (Michel Arruat) At the level of Device API. Existing base of Java applications LHC Power Converters CMW evaluation Special version to test thread-pool for asynch requests Had to go through Server Framework change Was suffering from non-existing release management CMW will provide asynchronous get/set support in server CMW is well-adapted to the problem, provides suitable architecture

9. CMW status 6 Feb. 2002 Supported clients (cont.) RF (Luca Arnaudon & Olivier Brunner) Got application for Kfocus using OPC server running in 2 weeks without previous Java knowledge Prepared to use CMW for a setup with Compact PCI and Acquiris card + OPC server + VME to control timing use Java Dataviewer to display mountain range SPS Passerelle project (Excel access) Dormant since the first version has been demonstrated Has to implement subscription. Can profit from new SL- Equip server.

10. CMW status 6 Feb. 2002 Supported clients (cont.) BI (BISCOTO) Technical discussion with JJ End of January Discussed all details No technical problems – waiting for JJ to go ahead with prototype Should be straightforward as API similar to SL-Equip

11. CMW status 6 Feb. 2002 SPS2001 and CMW Deadlock between End of 1999 and Oct 2001 Concept of contracts has been defined in-line with device/property model 1999/2000 MW evaluation and design Series of meetings Sept/Oct 2000 New SPS2001 Project Leader November 2001 6 Dec 2001 meeting between CMW and SPS2001 Kris makes a proposal on interaction CMW/Equipment/SPS2001 Concluded that SPS2001 will attempt to use CMW to access SPS BCT and Multitune measurements Attempt to understand measurements within SPS2001 19 December meeting on measurements, Kris asks for a simple measurement framework agreed with BI Attempted to analyze MKP server

12. CMW status 6 Feb. 2002 SPS2001 and CMW (cont.) Meeting Mid January Mike asks for a combined solution (SPS2001 server “plugged” into CMW) Michel defines “MW independent contract framework” Do not understand! If CMW should be used by SPS2001 Accept device/property get/set/subscribe model Define data representation (CMW or SPS2001 style) Should be possible to use CMW servers but a combined CMW/SPS2001 server framework is possible. Self-describing capabilities can be added easily to CMW servers. Additional requirements such as client ID can be added.

13. CMW status 6 Feb. 2002 October 2000 conclusion (by Kris) Kris reported from the 5 meetings in which he, Vito, Marc and Francesco from the MW team participated. For Kris the conclusions were not satisfactory as no edge-cutting decision was taken. Pierre Charrue has requested the following: Modifying the CMW and SPS2001 API's such that they are identical. (the conclusion from the presentation was that the API's are almost the same anyway). MW shall support requirements of SPS2001 such as automatic reconnection, client identification and "support for dynamic devices" the latter being a rather vague concept. SPS2001 shall provide precise contract definition. Kris reckons that there is no technical problem to fulfill the requirements, except that the "dynamic devices" would have to be better defined.
