  2. New Infrastructure • New TDB Infrastructure (since 2009-04-28): • New server: 2 quad-core CPU, RAM 16 Go • New Storage : EMC Clariion with a capicity of 1.5 To (RAID 10) • New HDB infrastructure (june 2009) : • New server: 1 quad-core CPU, RAM 16 Go • New Storage : EMC Clariion with a capicity of 2.7 To (RAID 5)

  3. New Infrastructure • Performance : • A temporary file with 1200 lines is recorded in 300ms instead of 10 secondes before. • Best response in MAMBO. • Now, we can : • backuped TDB each night. • Store 31 days of data and more. • The way to reduce the charge : • Export temporary file every 1 hour (instead of 30 minutes currently).

  4. New Infrastructure • Migration HDB to EMC storage is planned for june. The changes : • New server with better performance • 2.7 To can store several years of data online. Migration HDB to EMC storage is planified for june. The changes : • Extention of Oracle HDB service to beamlines is planned end 2009 • Use of a centerlized Data archiving infrastructure • Overcome current beamline deployment limitations

  5. ZOUK Project Goals • Supervise attribute quality and device state changes, and display alarm events. • Give Users the ability to configure the system themselves.

  6. Alarm Diary Software Architecture

  7. Device Roles • The AlarmDiary GUI (Macarena) uses AdbManager commands for each database transaction. • The AdbManager device dispatches alarm supervision between the existing AdbArchiver devices. • Every AdbManager command calls Adb api methods and gets responses from database.

  8. Device Roles • The AlarmDiary GUI (Macarena) uses AdbManager commands for each database transaction. • The AdbManager device dispatches alarm supervision between the existing AdbArchiver devices. • Every AdbManager command calls Adb api methods and gets responses from database.

  9. ADB API • Database Api: A factory pattern to differentiate specific Oracle and MySql syntax.  It allows connection and communication with ADB database. • AdbManager Api: An interface used by devices classes to select/insert ADB data.

  10. Alarm Diary Device • A synchronized event queue • Has two methods: i) read_alarm_event()(Used By the GUI) ii) write_alarm_event()(Used By the ADBArchivers) • Properties:

  11. AdbArchiver Device • Start and Stop supervision with two possible modes: • Periodic mode. • Disable mode. • Calls write_alarm_event for every new inserted event on AlarmDiary device • Properties:

  12. AdbManager Device • Load Balancing between AdbArchivers. • Manage alarm events Database • Manage contexts (configurations). • Properties:

  13. Macarena GUI • Display a supervised context as: - A tree of supervised and disabled attributes. - A table of alarm events: a thread is used to call read_alarmEvent() every second to refresh data. - A table of deleted alarm events: it’s possible to restore an event.

  14. Different Trees:

  15. Deleted Events:

  16. Display modes: • Full mode: display all events of the selected context. • Flow mode: display the last N events.  N is defined as a depth of the flow mode. • From date mode: display the list of alarm events from the given date. • Between dates: display the list of alarm events saved between the given dates.

  17. Display modes:(2)

  18. Context creation:3/4
