Introduction (0m 40s)
Configuring your system for DataFlex Web Development (4m 42s)
Next lesson:

This demonstration is shown on a machine that already has the DataFlex Studio Installer, Rewrite Module, and the DataFlex WebCheck tool downloaded. During the demonstration they will all be accessed from the ‘Download’ directory on the machine. Here are the links for those components:

  1. Start the DataFlex Studio Installer. Select NEXT.
  2. Select the “Run WebApp Check” button to discover what components are missing, and if there are any system warnings to be made aware of.
  3. In this demonstration, the core components of the Internet Information Services (IIS) web server are not installed, port 80 is closed, and a warning is shown for a non-interactive desktop heap size.

  4. Open and configure IIS…
  5. Navigate to “Programs and Features”
  6. You can get to it from the Control Panel or by searching for it.
  7. Select “Turn Windows features on or off” from the menu on the left.

  8. Select and expand “Internet Information Services” from the Windows Features window that opens
  9. Expand “Web Management Tools”
  10. Select and expand “IIS 6 Management Compatibility,” and confirm that the following are selected:
    - “IIS Metabase and IIS 6 configuration compatibility”
  11. “IIS Management Console” must also be selected if ISS is to be managed locally
  12. Expand “World Wide Web Services,” and under this section…
  13. Expand “Application Development Features”
  14. Select “ASP”
  15. Note that doing so automatically selects “ISAPI Extensions” as well
  16. Expand “Common HTTP Features,” and confirm that the following are selected:
    - Default Document
    - Directory Browsing
    - HTTP Errors
    - Static Content
  17. Expand “Health and Diagnostics,” and confirm that the following are selected:
    - HTTP Logging
  18. Expand “Performance Features,” and confirm that the following are selected:
    - Static Content Compression
  19. Expand “Security,” and confirm that the following are selected:
    - Request Filtering

  20. Press OK to start the installation
  21. Locate and run the DataFlex WebApp Check. Results should show:
    - IIS now appears to be installed
    - The application pool mode needs to be set to 32-bit
    - Optionally install the URL Rewrite Module
    - Desktop heap needs to be increased
  22. Set the default pool to enable 32-bit applications
  23. Start the IIS Manager
  24. Select “Application Pools” from the menu on the left
  25. Select “DefaultAppPool”
  26. Select “Advanced Settings…” from the menu on the right
  27. From the windows that appears, double click on “Enable 32-Bit Applications” to change it to TRUE
  28. Press OK to close the window
  29. Exit out of IIS Manager
  30. Install the Rewrite Module
  31. Open the Rewrite Module download (rewrite_amd64) and complete the necessary steps for installation.
  32. This module makes it possible for web administrators and developers to create rules that are easier for users remember and increases visibility to search engines.
  33. Open the Registry Editor (regedit) to adjust the size of the desktop heap
  34. Note: doing this will limit the total number of processes that can be run on a single server. Though, 768kB is generally enough for a desktop system, it is beneficial to increase the non-interactive desktop heap size on a web services system to allow for more processes.
  35. Change the Windows registry…
  36. Navigate to the following branch: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\SubSystems
  37. Select, open, and edit the “Windows” key by following the directions found in Knowledge Base article #1158, INFO: Session Limit Encountered When Running WebApp Server
  38. Run the DataFlex Studio Installer. Select NEXT.
  39. Rerun the WebApp Check
  40. All items are GREEN, and DataFlex Studio is ready to be installed!
  41. Complete installation of DataFlex
  42. To confirm all the setting…
  43. Open the DataFlex Studio
  44. Select “WebOrder.sws” from menu on the left of the Start Center to test a sample application
  45. Select the COMPILE icon from the top toolbar
