Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 2 Trigger Database Purpose: –Create, Modify, Store and Report all D0 Trigger Configurations in Run 2 –Generate configuration format: ‘xml’ for online and simulation –Document TDB is the first place collaborators look to get an understanding of the D0 Trigger System Requirements –Technical Generate a precise configuration for a complex device –COOR document (Scott Snyder) –D0 Trigger/Online Groups –Interface Store and retrieve configuration information from a Database for a User. –Functional –Usable –Documented

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 3 Trigger Database Statistics IN USE since December 2001 all Global (Physics) and nearly all Special Runs an increasing number of Commissioning and Calibration … configurations as functionality of trigger systems come online Contains nearly 100,000 records 340 Trigger Lists (3580 Triggers defined) single List can contain 1000s of parameters 236 Trigger Lists used online in >18000 Runs All data is entered by people (10 certified) Trigger Lists are a unique combination of conditions which are designed individually to configure a complex system Nearly no duplicate records Once a trigger list element is created, other trigger lists can use it not large by database standards but implementation is complex, reflective of programmability of the D0 Trigger System.

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 4 D0 offline production database instance (d0ofprd1) –About 40 Tables in Oracle –About 25 Views in Oracle TriggerDbServer Like the SAM db servers – a customized db server ** - interfaces using the TriggerDbServer Command line interfaces: –DeleteTemporaryElements.py** –CheckStatCurr.py** –CheckStatUsed.py ** –clientDemo.py ** –add_user.py –rcpGen.py ** –set_statUsed.py –xmlgen.py –GetBitNames.py –GetRuns.py –GetStuff3.py –l3tooltype.py –streamXmlGen.py Web based interfaces: –TDB Entry Interface (about 15 modules) ** –TDB Report Interface (about 15 modules) –TDB MISWEB Interface Documentation –Web based html or via TDB Report Interface. Trigger Database Implementation

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 5 TDB Status TDB meets some but not all of the requirements for its current capabilities –The ‘NOT ALL’ part wastes a considerable amount of expert time The system needs to be expanded –D0 Trigger Steering Committee The system cannot be expanded until its deficiencies for current capabilities are addressed. –Why: the same expert is involved so doing so will exacerbate the existing problem We need help from CD to bring the project up to the design specifications –Defined CD Project: d0.fnal.gov/d0dist/dist/packages/trigdb_ userweb/devel/www/TDB_Plan.html

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 6 Schedule for fixing/implementing Entry/Report client and DbServer trigdb_status, l1dialogs –4 weeks tdb_objects, terms, L1dialogs, neoterms –7 weeks tdb_scripts, tn, tl, tldependency –5 weeks trigdb_objects, terms, scripts, triggernames, triggerlists –7 weeks trigdb_tltransformation (expert required) –4-8 weeks t(rig)db_L2pp –5 weeks t(rig)db_ed, dg –4 weeks TriggerDbServer –convert from fnorb to omniorb

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 7 Schedule for Maintenance, Integrity and New Functions Enforcing system constraints –more checks insure correct configuration Performance Issues –needed Machine Issues –on order for Luminosity Database –RunS and Trigger to move away from SAM Clean up program –2-4 weeks (implementation dependent) Changes to Level 1 Exposure Group Rules –2-4 weeks Level 1 Pseudoterm Implementation –2-4 months Trigger List to Release correspondence –4 weeks Run 2b Changes –specification dependent Level 1 subdetector version tracking –specification dependent Additional COOR functionality –specification dependent

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 8 Who is working on what ? Help: CD/CEPA Database Group –Their expertise: database,database server, python, cgi Margherita Vittone, Vijay Murthi –TDB Entry/Report Interfaces learning TDB schema, business rules learning the existing implementation Steve White, Margherita Convert TriggerDbServer to omniorb Steve is the DB server expert (converted all other servers) Elizabeth –Bug and data fixes, data entry –Implementing expert features –Testing above changes –Certification for production

Jan 28, 2005Elizabeth_Gallas D0_Trigger_Database 9 Summary Trigger DB Server Steve White (a few weeks) –changes for conversion from fnorb to omniorb more pervasive than anticipated. Cannot cut new code to production until ‘issues’ in server and client are resolved. Trigger DB Client(WebInterfaces) Margherita Vittone (part of part time)& Vijay Murthi (<½ time on TDB project) –Both understand system to be tangibly contributing to the code base –Their code will be in next ‘prd’ release delayed by server changes –Limited by E’s time for testing etc –Available time varies for all of us working on other projects –Could accelerate project by getting more of their time (additional people adds startup)
