  1. ALICE DCS Workshop 14th March, 2006 JCOP Framework and PVSS News Piotr Golonka CERN IT/CO-BE Outline PVSS status Framework: Current status and future work Oracle archiver status Advanced course

  2. ALICE DCS Workshop Current Status: PVSS PVSS official release 3.1 Download from http://cern.ch/pvssregister Windows: available as a patch (SP2); already in the cumulative patch Linux: available as complete installation un-installation of 3.0 required if installed in the same folder Upgrade of 3.0 projects required button in System Management Panel Evaluation of PVSS v3.5 prototypes We got a few development snapshots, Final version expected in summer Some features being tested: new tree widget, trending widget, ... project version management (integrated with file tree panel of GEDI) embedding custom widgets: proof-of-concept Root canvas Framework compatibility and migration studies

  3. ALICE DCS Workshop Current status: Framework Current version is 2.3.6: Compatible with PVSS 3.1 Available from:http://cern.ch/itcobe/Projects/Framework/Download/welcome.html List of all improvements and fixes:on the download page

  4. ALICE DCS Workshop Framework 2.3.6: Tools NEW! Alarm Handling Component Customized alarm screen (filtering based on FW criteria) NEW! Complete reference help Accessible from the main panel of the (new) installation tool Access Control Upon the decision of FWWG, the integration of AC mechanisms in device panels is up to developers now minimal functionality may be provided by the Framework Trending Tool Improved template functionality Each instance of a template plot in a page may have separate parameters Cooling and Ventilation Application Proved to work with SPD Next tests in ALICE with HMPID Not (yet) distributed with the framework

  5. ALICE DCS Workshop Framework 2.3.6: Tools Configuration Database Tool Supports HARDWARE and LOGICAL hierarchies Recipe templates (aka recipe-per-device-type) Used by many sub-detectors now FSM Alarm handling based on summary alarms Setting the state of a DU from a script The user gains control of when the state-transition happen Its use may lead to performance improvements (eliminate dpConnects)

  6. ALICE DCS Workshop Framework 2.3.6: Devices ELMB v. 3.2.2 Custom PDO's for analog inputs Possibility to define a “raw value” sensor Wiener Maraton Released now Requires new OPC server from Wiener (1.0) CAEN The list of supported boards is now available in the component's documentation:DE&N->Open Installation Tool... -> “Help” next to “CAEN” No support for SASY (use of EASY recommended by CAEN)

  7. ALICE DCS Workshop CAEN component documentation...

  8. ALICE DCS Workshop Future Work (Framework Tools) Access Control Synchronization of AC in a distributed system: “domain controller” (?) to be discussed by FWWG Trending Tool Taking advantage of new trending widget of PVSS 3.5 Step1: (summer release) compatibility with existing functionality Step2: (later) integration of the new features Configuration Database saving/restoring of device configs (next version) Improve performance of DB access layer Integration with FSM tag/version management (API, panels) API and documentation clean-up

  9. ALICE DCS Workshop CAEN Integration of AliceBox Requires discussion with Ombretta Two other EASY modules: A3486, A3801 ELMB ATLAS is working on SPI integration BCAM (alignment cameras) Will be integrated in April (Sorina, Oliver) Future Work (Framework Devices)

  10. ALICE DCS Workshop PVSS Oracle archiver status New version in patch 167 Available on request (from DCS coordinator) Client side Big performance improvement 1000 changes/s Windows 2000 changes/s Linux Limitation is PVSS itself, not RDB DB server side High CPU load Big overhead: ~200 bytes to store a float Timestamp, quality, manager, etc Indexes to speed up queries DB internal overhead Dedicated IT/CO server could only handle 4 clients with a total of ~5000 changes per second

  11. ALICE DCS Workshop PVSS Oracle archiver status Current work at CERN Testing with different DB servers Finding ways to reduce load on server Contact with Oracle consultant Testing with many clients (help from S. Kapusta) Current work at ETM Simplifying the set up procedure Working on buffering when DB not available

  12. ALICE DCS Workshop Advanced Framework Course ... for really advanced PVSS users Contents: Recap on JCOP Technologies (FSM, Fw devices) DIM Access Control component CNIC (security) awareness and tools Alarm handling Integration of custom devices into the framework Configuration Database Tool Integration of control hierarchies More details, dates and registration: http://itcobe.web.cern.ch/itcobe/Services/Pvss/Training/welcome.html Contact your central team (ACC)
