Visual DataFlex
12
Web Application Server (WAS)
The Visual DataFlex
12 Web Application
Server is the successor to WebApp Server 3. Numerous important features
and changes have been introduced, and server performance and efficiency
is significantly enhanced.
Preliminary performance tests of the Web Application Server produced
the following results:
 |
A loop containing 5,000 get/set
properties that takes 58 seconds in WebApp Server 3 takes only 3 seconds
in Web Application Server!
|
|
Retrieving 1,000 records from a database
takes 15 seconds in WebApp 3, but only 2 seconds in Web Application
Server!
|
|
The Microsoft Web Stress tool running a
simple application script shows WebApp 3 serving between 7-9 requests
per second, but showed Web Application Server serving between 71-73
requests per second!
|
The Visual DataFlex Web Application
Server shares a common technology foundation with the components used to
build and deploy Windows applications. This enables the development and
interchangeable use of application code, data dictionaries and
components for both Windows and Web applications.
Additional enhancements to the Web
Application Server include new features added to the Administrator that
expand its functionality and enhancements to improve usability, easy
transition from WebApp Server 3 to the Web Application Server (as
the new server can run "side-by-side" with previous revisions), and
improved error handling and error messages.
Web Application
Server Licensing
Visual DataFlex Web Application Servers execute Web-based application
software developed with Visual DataFlex Studio. Web Application Server's
components include the application execution engine, a COM-based
interface to Microsoft's Internet Information Services (IIS), database
utilities, the embedded database and, optionally, database connectivity
drivers. A Visual DataFlex Web Application Server license is required
for each hardware server on which a Visual DataFlex web application is
installed.
Web Application Server
Licenses
|
Internet Edition
- Supports unlimited number of concurrent sessions or browser
connections subject to the limits of the Web Server's resources and
Internet infrastructure. Supports process pooling. The Internet Edition
license allows users to host commercial websites. |
|
Enterprise
Edition - Manages the combination of up to 255 Internet
Edition servers in a cluster configuration to allow for highly scalable,
load-balancing, fault tolerant web application servers. Each Web
Application Enterprise Server "master" connects to n-Web Application
Internet Server "slaves" to create a highly scalable application
architecture. |
|
Lite Edition
- Supports up to 5 concurrent sessions and does not support process
pooling. Electos can be deployed on a Lite Edition server, however, due
to its session limits, the Lite Edition server is not recommended for
production websites. |
Note: A Lite Edition server comes with
the Visual DataFlex Studio however it is licensed for development &
testing only and cannot be used for application deployment.
Annual Subscriptions are available for Visual DataFlex Web Application
Servers to provide application customers with all updates and
enhancements delivered by Data Access during a one year period.
Evaluation Web Application
Server
A ready-to-install, Visual DataFlex
12 Web Application Server intended to
be used by web application developers as an embeddable platform upon
which to distribute evaluation versions of their solutions to
prospective customers. The Evaluation Web Application Server is limited
to 5 concurrent sessions (just like the Lite Server) and will
automatically expire and cease to operate 30 days following installation
on a given computer system. Specific terms and conditions of use are
defined in the License Agreement. An Evaluation Web Application Server
can be “activated in place” to enable a customer to use the application
without re-installation.
