  2. Welcome Oracle and Linux A match for technologists who need 100% uptime on mission critical applications A solution moving you forward into the next millennium Performance Scalability Reliability Cost Savings

  3. Welcome • Oracular Systems and Software • Over 12 years of technology experience • Systems experts in eBusiness ERP Systems Integration and Implementation Oracle Database Management Applications Development Web Services Network and Systems Design Data Warehousing

  4. Today’s Agenda • What is Linux? • Why Linux? • Comparison with NT • Oracle on Linux Demonstration • Conclusion

  5. What is Linux? • Linux Origin • Free Software Declaration • Open Source Benefits

  6. What is Linux? Origin • Inventor Linus Torvalds • The New eDistribution Channel For Software • The best things in cyberspace are often free • After more than 20 years of trying to develop a market in proprietary software, developers seem to have found a method that works: give it away • Free market on the web allows people to compete on the basis of the elegance and utility of their programs, like the Medieval craft guilds and Renaissance artists

  7. What is Linux? Open Source • A Myriad of Developers Working Towards a Common Goal • Corporate software is generally built according to a predetermined plan that leaves little room for deviation or innovation • The logic of the intellectual marketplace ensures that only the best code and overall structure, as judged by a programmer's peers, will survive • Open Source OS can be customized immediately based on market, business, or personal requirements

  8. What is Linux? Open Source Benefits • Technical Support for Free Software? • Plentiful research: Archives of Usenet articles about Linux contain about 200,000 postings, with 1,000 or more added every day • Web sources: Linux web pages number over three million • Access to resources: Programmers who write the code communicate directly with those who use it • Growth of strong support structures: Paid support agreements like ones offered by Red Hat

  9. Why Linux? Key Factors • UNIX Based, POSIX Compliant • Linux Kernel Open Source Software • Multitude of Flavors Available • Tailored for different environments, including “enterprise” • Rapid Errata Available • Sizable open source community working together

  10. Why Linux? UNIX Based • UNIX’s Longstanding Reputation of Reliability, Scalability, and Stability • OS Developed For Ease Of Use By Programmers Offers Less Built-In Overheads • By Inherent Nature OS Enables Features Not Available Elsewhere • Best Scripting Languages Available Within OS • Perl, Bash, CSH, KSH, Python

  11. Why Linux? Open Source • No One Can Dispute the Strength of Myriad of Developers Working to Fix a Common Software • Open Source Peer Review Allows for Quick Dissemination of Bugs and Overall Improvements of Software • Allows a Snowball Effect, Giving the Whole Product a Look of Refinement

  12. Why Linux? Rapid Bug Fixes • Since User Domain of Linux Is Also That of Programmers, a Constant Effort of Code Fixing and Software Improvement Is in Process • Bugs Are Found, Discussed, Fixed, Tested, Fixed, Enhanced -- All by These Skilled Developers • No Single Company Can Afford to Keep Such a Group on Payroll and Demand Such High Standards

  13. Why Linux? Comparison With NT • Competes On Same Hardware • Intel, Alpha (Sparc, IA64, and RISC) • UNIX Shells Versus DOS shell • Issues with NT overhead • Windows2000 Aspirations • Cost

  14. Oracle on Linux Database Server Optimization • NT Has OS Overhead That Cannot Be Optimized for a Database Server • Linux Allows to Selectively Switch Off Unnecessary Services • Necessary drivers are compiled into kernel • Kernel Modifications To Boost Server Performance • I.e., only necessary drivers are compiled into kernel • Linux Allows for Selective Start/Shutdown Services • I.e., SCSI and Ethernet

  15. Oracle on Linux UNIX Robustness • Shell Scripting • I/O Management • Memory Management • Process Management • Resource Allocation and Limits • Security

  16. Oracle on Linux Oracle Database Specifics on Linux • Database Versions Available • Installation Problems • Concerns with Client Software Connecting to a Different OS(Demo)? • Cost • Converting to Linux From Other OS • Application data • Licensing • Database Applications That Can Benefit From Linux

  17. Oracle on Linux Database Versions Available • Oracle Started Porting Releases to Linux With Its Oracle 8 Versions, Including 8.05, Then 8i • Oracle Is One of Few Vendors Supporting Key Internet Technologies Like Java and XML in the Database • With Its Bundled Availability on the Inexpensive Linux Platform, Oracle Is the Leader in Providing Essential eBusiness Technology for Start-ups

  18. Oracle on Linux Database and Tools Available • List of Database Versions Available • Server Products (8.0.5.1, 8.0.6.1, 8.1.5 and 8.1.6) • Oracle Directory 2.0.6 • Oracle Application Server 4.0.8.1 • Oracle Web DB (2.0, 2.1 and 2.2) • Oracle Developer 6i (Q2 Release in 2000) • Oracle Applications 11i (Q2 Release in 2000) • Oracle Internet Messaging 5.0 • Oracle iStore (iStore 3.1.1.5 and iPayment 3.1.1) • Oracle Discoverer Server 3.3 (Q2 Release in 2000) • Enterprise Manager with Intelligent Agents

  19. Oracle on Linux Installation Issues on Linux • Linux Supports the Java Based Universal Installer for Platform Independent Installation • The Orainst Installation Utility Enables Users to Custom Install or Upgrade Oracle 8 Distributions Along With Selected Options • Base System Requirements • Java Runtime Environment • Pentium processor • 48 MB RAM • 275 MB hard disk space • Linux base version 2.2 • RedHat 6.0 (runs through other distributions)

  20. Oracle on Linux Client Software Issues • Client software(SQL*Plus, etc) can Connect to any Server Platform, Including Linux • All SQL*Plus and PL/SQL Scripts Would Work Seamlessly in the New Environment, Regardless of Original OS • JDBC, OCI, SQLJ and third party ODBC drivers all available • Oracle Import/Export Is Best Option to Convert Data for Data Transport Between Servers • Connecting Windows clients to Linux/Oracle Database- Issues & Demonstration

  21. Oracle on Linux Oracle Deployment Cost • Oracle on Linux Is Not Free, Base OS Is • Customers opt for Linux because of features and not simply because Linux is free • The Oracle on Linux Decision Is to Deploy the Best Database on an Excellent OS • Overall Cost of Ownership Still Low (No OS License Fee Per User - Can Add Significantly to Solution) • Many Products Like Application Server and Web DB Are Free for Developers • Trial Licenses Are Extremely Inexpensive

  22. Oracle on Linux Converting To Linux • Oracle Import/Export Is Best Option to Convert Data • NT Requires Shell Script Modification • Any Upgrade Requirements As Dictated by Oracle If Version Change Is Also Occurring • Licensing Considerations Should Be Made If the Source Database Will No Longer Be in Service • If your hardware configuration does not change, license should convert over at no additional cost

  23. Oracle on Linux DB Application Considerations • Linux Provides Superior Performance in Memory Management, I/O and Uptime • Web Applications Requiring 100% Uptime Benefit Significantly • Low Cost Solutions Where OS Cost Can Add Significantly Can Benefit • Users Looking to Maximize Life of Older Machines Can Deploy Test Applications Using Oracle and Linux
