  1. Gweb: GCOS on the Web Fast, Inexpensive and Safe Eye On The Information Solution 2000 Michael Sandøy

  2. Access to Corporate Information Today • Mission critical data on your mainframe • Data entry and retrieval by trained staff • ‘customers’ at the counter • ‘customers’ on the phone • requests by fax or mail • Using an old-fashioned terminal display • and modern network access to GCOS with Glink and Ggate • very good response times • very efficient user interface for the experienced user • not for a new employee or the infrequent user

  3. Maybe you have screens like this? • AUTOSYS administrates all Norwegian cars and driver’s licenses

  4. What you want is …. • Customers and suppliers to take part in the data-entry / data-retrieval process • To modernize the user interface to your mainframe data • To protect your investment in reliable and responsive data storage • And ….. • You want it NOW!

  5. The Solution is Gweb • Web-enables your mainframe applications • No changes to your mainframe hardware or software • Nothing but a standard browser on the desktops • Installs on a UNIX or Windows NT / 2000 server • No programming of any kind required anywhere • …but you can do that too!

  6. Your own wall paper Your own logo Data entry fields with 3D effects Mouse-activated function keys Your own footer Automatic Facelift

  7. Web server Netscape, Microsoft, Apache, Gweb HTTP server Facelifter (Host forms to/from HTML) VIP7800/DKU/3270 Emulator G&R line handler Gweb Standard Edition IBM system TN3270 gateway Web browserNetscapeMS-Internet Explorer TN3270 SNA Gweb CGI GCOS system MainWay TNVIP DSA DSA Ggate DSA

  8. Browser Meets Gweb • Connection initiated from Web page

  9. Web server Netscape, Microsoft, Apache, Gweb HTTP server Facelifter (Host forms to/from HTML) VIP7800 Emulator G&R DSA line handler Gweb Start-Up Browser connects to the server Gets the first screen Then the browser is disconnected Web browser Gweb CGI GCOS system Host session kept up First screen from host DSA

  10. Web server Netscape, Microsoft, Apache, Gweb HTTP server Facelifter (Host forms to/from HTML) VIP7800 Emulator G&R DSA line handler The Next Transactions Browser connects to the server Gets the next screen The browser disconnects Web browser Gweb CGI GCOS system Host session kept up Next screen from host DSA

  11. Auto-Facelift at UW-River Falls • Student Online Access to Records (SOAR)

  12. Gweb Security • The Web Server • allows you to protect access to web pages • A Secure Web Server • Security certificate shows identity of site • encrypts/decrypts data to/from browser • Gweb • creates a random 8-character password which is unique to this session • screens include hidden fields • Session ID • Password • Sequence number

  13. Gweb Standard EditionSummary • Legacy applications instantly on the web • No manual facelifting work necessary • Nothing to install on the client side • Central configuration and administration • Optionally private, encrypted connection • Appropriate for simple applications • Web-friendly forms can be added to existing host applications using host programmingtools and host programmers!

  14. Web server Netscape, Microsoft, Apache, Gweb HTTP server Custom designed facelifter Gweb's default facelifter G&R line handler Gweb Professional Edition Web browser Gweb CGI Perl Scripts index.cfg

  15. The Facelift Process 1) As you step thru the host forms, they are captured on disk 2) Using the captured data, identify unique forms 3) A facelifting configuration file is created or updated gwebedit.exe index.cfg 4) Using your favorite HTML editor, modify Gweb HTML, or create your own. All fixed/variable data from the host screen is available. Macros can skip display of specific screens.

  16. Write HTML to Replace the Default Form • The original screen contents, including input fields, are available for use • Buttons, optionally with your own text, for emulation function keys or macros

  17. Automatic Reply Pattern match patterns: ident IDNT1 <@1,24 ident: Macro @0@Tmike@Tmypasswd@E <Home> <Tab> mike <Tab> mypasswd <Transmit>

  18. External Scripts • The script analyzes the host screens • communicates further with the host system • remembers data between host transactions • in the end it formats a HTML screen for display in the browser • patterns: • result Search Results: @2,2 • result: • Script perl result.pl Script program

  19. Gweb 3270 to SIRIS

  20. Gweb 3270 Pro - with Perl

  21. 7800 Web8 Gweb as Web8 & TDS-Web Gateway • Automatic detection of ‘Web8’ format • Dynamic switching between ‘Web8’ and ‘Terminal’ format • Web8 URLs bypass the emulation engine • Web8 HTML is delivered direct to the browser

  31. Inexpensive & Scalable • In-house tests on small Intel (Pentium III, 256MB RAM) with Windows NT, Windows 2000 or Linux • 500 simultaneous DSA sessions • 20% CPU usage • Extremely good turn-around times (40ms) • Facelifting introduced no measurable overhead • More sessions requires only more memory • But Gweb is also supported on more powerful server platforms like • AIX, Solaris, HP-UX, OSF-1
