  1. IceCube Offline Database Overview Georges Kohnen Université de Mons-Hainaut 15.08.2007 IceCube Software Bootcamp

  2. Introduction • MySQL Database, “I3OmDb” • Contains most of the non-physics information needed by offline-software, on the SouthPole, on a cluster or on your laptop: • Detector Geometry • InIce/IceTopCalibration • Detector/DOM Status and Trigger • Run Information • Monitoring information • Ice Properties • AMANDA and TWR information • Different “lookup” tables • Internal (bookkeeping) tables that keep track of • Updates and Revisions • Start and End times of records • Comments 2

  3. To be done • Store monitoring information from “human” detector monitoring • Store Verification information (Bad DOM lists,...) • Store Flasher data? • Implement “Garbage” or “Temporary” database? • ... 14

  4. Introduction • The stored information is time -based • Records are “stacked” on each other • Example: Geometry “Qualifier” Drilling01/2006 Corr02/2005 Drilling01/2005 Initial Drilling: lots of strings Better calibrations: only string 21 Drilling: only string 21 Planned Geometry, whole detector Time 01/2004 01/2005 01/2006 4

  5. Geometry tables • AMANDA Geometry • Planned geometry (IceCube80 with IceTop) • Drilling/Installation Season 1 (string 21 and stations 21, 29, 30 and 39) • Corrections to these coordinates (from Kurt) • Drilling/Installation Season 2 (strings 29, 30, 38, 39, 40, 49, 50, 59 and stations 38, 40, 47, 48, 49, 50, 57, 58, 59, 66, 67, 74) and Corrections • Drilling/Installation Season 3 • ... 5

  6. Filling the Database • Since this Pole Season: automatic update of Run details, Trigger data and Detector Configuration/Status from DAQ on Pole DB for online use • Then, regular synchronization of SouthPole I3OmDb with a reference Database in the northern hemisphere, and overall synchronization with this reference DB • Manual updates/filling of non-regular data: Geometry, Domcal,... F

  7. Using the I3OmDb Database at SouthPole PnF / Offline Software on SouthPole Source modules Other modules DAQ … Automatic synchronization of Pole and reference DBs (c.f. RevisionId) I3Db services Fill run, trigger and detector status information automatically SouthPole I3OmDb Reference I3OmDb 10

  8. Using the Database in offline-software • I3Db project in offline-software (~11000 lines of code): new design: not one monolithic piece of code anymore, but • one service for each stream (geometry, calibration, detector status,…) • Conversion services (OMKey2MBId, OMNumber2OMKey,...) • one database service, responsible for connecting to the Database, retrieving/caching the data,… I3Db retrieves the information according to the date of the event I3Db services I3OmDb “hot-pluggable” Physics input Muxer / Modules Other modules Offline chain of modules … 11

  9. Practical Information • Primary redundant Database server: icedb.umh.ac.be (also containing information about the content of the Database and about the I3Db services, as well as a public web-interface) • Mirrors: ppemons.umh.ac.be, dbs2.icecube.wisc.edu (should be used from the USA) • Database Name: "I3OmDb" • Read-only login: username "www“ (> mysql -h "server" -u www) • Recommended tools for “brute” access: • MySql Query Browser • MySql Control Center 12

  10. Demonstrations • 4 ways to get info from the database • Python script in IceTray • Stand-alone program (MySQL Query Browser) • Database browser (web interface) • Terminal access (see bootcamp website for small tutorial) • Database website with documentation, web interface, status page and this .ppt presentation: http://icedb.umh.ac.be 15
