  1. DCS Databases status ALICE Week Svetozár Kapusta

  2. Status • FERO configuration DB • Redundant installation ready at P2 • PVSS FW configuration DB • Redundant installation ready at P2 • Thanks to Jacek WOJCIESZUK (IT/PSS) • PVSS archival DB • We are finalizing the HW specifications • Will be installed in early 2007 • ETM still needs to implement pending CERN requirements ALICE Week Svetozár Kapusta

  3. Policies • Ask the central team for an account • One account per one sub-detector • If you have already configuration data at your home institute DB: • use the Oracle export utility to export the data • Upload the data to LAB fileserver (See slides of Peter Rosinsky) • ACC will upload the data to CR3 and import it into the DB ALICE Week Svetozár Kapusta

  4. Oracle Export • You can export • Entire Database • Users • Tablespaces • Tables • On the server command line type: • exp system/password owner=(SchemaToExport) • Or just type exp and answer exp’s questions (do not hesitate to ask ACC for help if needed) ALICE Week Svetozár Kapusta

  5. FW Configuration Tool • Uses ODBC • To connect to your DB – Instant client is required on your client PC (in CR3 installed by ACC) • Remark (CERN NICE specific): • Standard NICE PC @CERN have Oracle tools v6 installed • To be able to connect to DB: • uninstall Oracle tools v6 • install InstantClient with ODBC extension • setup properly the ODBC connection (do not hesitate to ask ACC for help if needed) ALICE Week Svetozár Kapusta

  6. AMANDA • Current version 4.1 (based on PVSSII API) • Download available: http://alice-project-dcs-amandaserver.web.cern.ch/alice-project-dcs-amandaserver/ • Known bugs fixed • Tests completed • Beta version of Windows based client (DCS client) available • Offline (AliRoot) client available in OCDB framework • Reduced version available from DCS web page (Linux only) ALICE Week Svetozár Kapusta

  7. AMANDA Performance • Test results: • Transfer rate (reading from files): • ~10000 DPE/s (~80kB/s) Offline client • ~15000 DPE/s (120kB/s) DCS client • Transfer rate (reading from Oracle): • ~8000 DPE/s (60kB/s) Offline client + DB archive (final version will bypass PVSSII API) ALICE Week Svetozár Kapusta

  8. AMANDA testsOffline client + DB archiving • Reading while archiving into DB • Connection overhead not excluded • Using offline client ALICE Week Svetozár Kapusta

  9. AMANDA testsOffline client • Reading while archiving into files • Connection overhead not excluded • Using offline client ALICE Week Svetozár Kapusta

  10. AMANDA testsDCS client • Reading while archiving into DB • Connection overhead not excluded • Using DCS client ALICE Week Svetozár Kapusta

  11. Thank you for your attention ALICE Week Svetozár Kapusta
