  9. DSS Decision Support System

  10. DECISION SUPPORT SYSTEMS DEPARTMENT • MISSION OBJECTIVES: • Maintain current, accurate, reliable database • Promote & integrate use of decision support • Improve &/or expand DSS functionality

  11. Robert Hutchinson ext. 16197 David Mischick ext. 17258 • IT Sr. Technical Analysts: • Data conversions & flods into DSS • Complex data extractions from DSS • COBOL programming • DSS “Webmaster” • System performance and maintenance • Technical aspects of software upgrades and enhancements

  12. Three Online Regions • TSIPROD – Available M-F 8am to 7pm • TSIDEV – Available M-F 6:30am to 8pm • TSITEST – IT usage only

  13. DATA COMPOSITION FEEDER/SOURCE SYSTEMS: LAWSON G/L & PAYROLL SMS, IDX & AMISYS PERM GROUP: 2 Prior FY’s + Current FY available in TSIPROD routine reporting by users TEMP GROUP: Perm Group + 1 add’l prior FY available in TSIPROD M204 adhoc reporting by DSS staff

  14. TSITEST

  15. Just a few lines from Eclipsys … Characters - 91,732,330 Lines – 2,490,074 Statements - 1,518,960 5,480 PROCEDURES IN 30 FILES Approximately 200 databases

  16. What will we focus on for today? 3 Files STDCOST ALBDATA ALBMAST

  17. How will it be done? • Slowly, Carefully, Organized • MacroExpress • 3Step JCL reorg using FAST REORG

  18. ALBDATA after 3Step Reorg Note: Total time = Total Time of records unloaded to temp dataset in seconds

  19. Search for KEY and ORD NUM COMBMDL IP NUMBER COMBMDL IPD NUMBER PMRTABLE HOLIDAY YYMMDD PMRTABLE SEQUENCE PMRVOLS TF BEG DATE PMRVOLS TF END DATE Search of 90 text documents = 5 seconds

  20. STDCOST – 7.8 MILLION RECORDS STEP010 10/11/05 Page 5 FUNL0055 Unload statistics : Base buffer reads = 6025 Base buffer waits = 2984 Extension pg in base buffs = 112 Extension pg in exten pool = 141237 Extension buffer reads = 781 CPU time = 14.513 Waiting for CPU time = 61.638 Open wait time = 0.032 Output buffer wait time = 0.291 Base buffer wait time = 24.599 Extension buffer wait time = 12.233 ---------- Total time = 113.306 Maximum 24 bit storage used = 452504 Maximum 31 bit storage used = 50113344 Fast Unload Report Job/step TS204RHA STEP010 10/11/05 Page 6 FUNL0055 Index unload statistics : Extension pg in exten pool = 280679 Extension buffer reads = 786 CPU time = 5.815 Waiting for CPU time = 10.158 Output buffer wait time = 0.280 Extension buffer wait time = 7.947 ---------- Total time = 24.201

  21. STDCOST – 7.8 Million ALBMAST – 1.3 Million ALBDATA – 7.1 Million 7Step initiated 7:31 AM Completed 11:18 AM (228 minutes) 3Step initiated 11:34 AM Completed 11:46 AM (12 minutes)

  22. MAJOR BENEFITS • Superior Customer Support • File reorganization time cut • Up to 3/4th time saved on large data files • Nightly batch would start sooner after the reorg • Reorganize more often initially to fine tune file structure • Reorganize large files at mid if necessary with minimal impact on end users • Less record extensions = Faster search = Faster response time. • This holds true for online and batch. • Less CPU usage
