1-2 Oracle Web Application Server™ Installation Guide
Oracle Web Application Server 3.0.1 operates across a wide range of operating
systems, from PCs to workstations, and through its open cartridge API, supports
a diverse class of languages and applications. Oracle Web Application Server
3.0.1 is the first Web server to support real transactions and it does so using X/
Open DTP standards.
Note: A cartridge is a program, run on the server by the Web Request Broker (WRB),
that interfaces to a Web server (Oracle or otherwise) through the WRB API. A
given cartridge will have a varying number of execution instances called
WRBXs.
Transaction Enable your Netscape or Microsoft Server
The WRB is portable not only across a range of operating systems, but across a
range of Web servers. Oracle bundles its own HTTP listener with Web
Application Server 3.0.1, but this portability means that it can also integrate with
Netscape and Microsoft listeners. This allows application developers to protect
their existing investments as technological infrastructures change.
Scalability
Building a presence on the Web can expand horizons considerably, but only if
your Web site can perform and scale to support the vast Internet audience.
Oracle Web Application Server 3.0.1 can scale to serve tens of thousands of users.
Through the WRB, Oracle delivers vastly superior performance, dispatching,
and access times, even in the extremely high network traffic environments that
are synonymous with the Internet. Built to a true multi-threaded, multiprocess
architecture, the Web Request Broker offers a superior application environment
over low-level, first generation HTTP APIs.
Reliability
A mission-critical application demands high availability. Oracle Web
Application Server 3.0.1 brings the robustness and reliability of the client-server
world to the Web. Process separation, an object architecture, and independent
cartridge management allow administrators to build, manage, and service their
system on a component basis. Through its independent processing architecture,
the WRB guarantees that third-party server extensions will not affect other parts
of the system security.
