  1. I07 – Open Source and IDS Major Canadian Retail Drugstore’s Prescription For Success Jordan Bruce Tuesday 3rd October 2006 • 15:15 – 16:15

  2. Major Canadian Retail Drugstore's Prescription For Success Migrating to IDS 10.00 on LINUX SuSe Sles9

  3. Jordan Bruce, Sr. Database Administrator • 8 Years DBA Experience • Former President of Ontario Canada Informix User Group • Lead Senior DBA at Canada’s leading retail drugstore • Database Administration Experience with IDS, Oracle, and SQL Server • Currently Administering over 1000 IDS Instances across Canada for one of the countries largest retailers

  4. Case Study of Large Scale IDS 10 Migration: • Going From SCO to Open Source Linux • What Was Involved With Our Migration of Over 100 Server Sites • Performance Gains Achieved With New IDS 10 features

  5. Who We Are… • Canada’s Largest/Leading Drugstore Group • Operating Since 1962 • 30,000 Employees • 1000 Retail Drug Stores Nation Wide • 7 Billion in Total Revenue for 2005

  6. What is our Pharmacy Application? • Allows Critical Health Information to be Securely Accessed by Healthcare ProfessionalsIn-House Developed J2EE Pharmacy Application • GUI Front-End • Replaces Old Legacy Pharmacy Application • Uses JMS for inter process Communication

  7. Factors leading To Migration • Slow Performance of Pharmacy Application • Insufficient Support on SCO • EOL for Current Platform • Increased Stability on IDS 10.00 • Simplified Administration on IDS 10.00 • Open Source OS Licensing Cost • No further migration from IDS 9.30 on current platform • No future support on current platform for Application Server (WebLogic 7.1)

  8. Migrating From… • OS: SCO OpenUnix 8.0 • Also known as Unixware 7.1.2 with LKP • Hardware: Proliant ML370 G • Network: 100Mbps • Application Server: BEA Weblogic 7 SP 1 • RDBMS: Informix IDS 9.30 UC7

  9. Migrating To… • OS: SUSE LINUX Enterprise Server 9 (i586) • Kernel 2.6.5-7.155.29-bigsmp • glibc-2.3.3-98.38 • Hardware: IBM e326 AMD 1U • Network: 100Mbps • Application Server: BEA Weblogic 8.1 SP4 • RDBMS: Informix IDS 10.00UC1

  10. Improved Performance with IDS • IDS 10.00 UC1 vs 9.30 UC7 - 8.82% • Configurable Page Size – 34.97% • 4kb page size for I/O intensive DBSpaces • 16kb page size for temporary DBSpaces • Prepared Statement Cache - 16% • DS_NONPDQ_QUERY_MEM • OPTCOMPIND

  11. QueryPerformance 49% improvement for queries

  12. QueryPerformance ‘ The Data’

  13. ApplicationPerformance Roughly a ~62% Improvement for Application

  14. OS Performance Roughly a ~39% performance gain

  15. Ease of Administration • External Optimizer Directives • Reorganizations Made Simple By Renaming DBSpace • Single User Mode

  16. Security • DBCREATE_PERMISSION • Secure Environment Check

  17. Increased Stability • Uninterrupted Service at all 114 sites across Canada since implementation

  18. Higher Availability • Point-in-Time Table Restore • FAST_RESTART_PHYSLOG and FAST_RESTART_CKPT_FUZZYLOG • Online Index Build

  19. Benefits • Migration from IDS 9.30UC7 to 10.00UC1 – 0 problems • Seamless Migration • End Users Extremely Pleased With Results • No effort required for Stored Procedures / Triggers • Weblogic using latest J2EE Standards

  20. Discover – In-House Asset Management System • Developed using shell scripting, Expect, XML, Java, Informix, JavaScript, PHP, ADOdb for PHP, HTML and CSS. • Web Application is hosted on a Linux server using Apache. • Store search web interface – provides info by store number • Management reports web interface – provides quantified info about all stores

  21. Discover – Store Search Screenshot

  22. Discover Web – Why use PHP? • PHP (http://www.php.net) – Server-side Scripting Language • Obvious Benefits of Open Source - It’s Free • Quick Development • Platform Independent • Plenty of Other Open-Source Tools for PHP that can be Used • PHP in Combination with Apache Remove of the Need for an Application Server. • Not Forced into OOP • If Business Logic is Managed Well by the Database Design, the Application Does Not Need to be Complex for Simple Display/Search Capabilities

  23. Discover Web – Why use ADOdb? • ADOdb (http://adodb.sourceforge.net/) • One of the Fastest Open Source Database Abstraction Library for PHP (and Python). • Licensed Using BSD and LGPL. • Providing Portability Over a Variety of Databases Such as MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Access, DB2, etc. • Full PHP5 Support

  24. Discover – Sample code using ADOdb • ADOdb Database Connection $dbdriver = ‘informix’; $db = ADONewConnection($dbdriver); $db->PConnect($server, $user, $password, $database);
