Challenges of Creating and Maintaining
E-Business Applications
The common challenges when creating and
maintaining e-business applications are:
• Development related
• Deployment related
You can meet the challenges mentioned above by
leveraging an integrated, complete, and open
e-business platform.

Challenges of Creating and Maintaining E-Business Applications
When you create e-business Web sites, some common challenges that you might encounter
are:
• Development related: When you create applications, depending on the requirements,
you must ensure that these applications:
- Meet Java 2 Platform, Enterprise Edition (J2EE) standards

- Interact directly with other software applications by using Web services
- Can be wireless enabled for rapid access through mobile devices
- Can be integrated with new business processes
• Deployment related: After your application is deployed to the server, it is important
that the server can deliver the appropriate content to users quickly and reliably. Some
of the challenges here include availability, scalability, performance, caching, systems
management, and user and security management.
It is, therefore, very important to leverage a complete and integrated e-business platform for
building an e-business solution.

Oracle Application Server: Overview
Oracle Application Server is a standards-based application server that offers a fully
integrated platform to develop, deploy, and administer Internet-based applications. The
following section describes the solutions that Oracle Application Server provides to address
the development and deployment challenges.
HTTP Server, J2EE, and Web Services
• Oracle HTTP Server functions as the HTTP interface for all Oracle Application Server
components.
• Oracle Application Server is built on the J2EE framework. It enables you to design,
develop, and deploy dynamic Web sites, portals, and transactional applications by
using familiar languages and technologies.
• Oracle Application Server also provides comprehensive Web services to expose
business functions to authorized parties over the Internet from any Web device.
Portals
• You can use Oracle Application Server to build, deploy, and maintain self-service and
integrated enterprise portals. Oracle Application Server enables self-service content
management and publishing, wizard-based development, and deploying, publishing,
and consuming Web services on an extensible framework.
Oracle Application Server 10g R2: Administration I 2-4


Oracle Application Server: Overview (continued)
Wireless
• OracleAS Wireless provides a simplified development and deployment of applications
in a wireless environment. In addition, OracleAS Wireless includes wireless services
(such as e-mail) and location-based services that simplify wireless-enabling of
applications and portals.
Caching
• Oracle Application Server provides a Web-caching solution with the unique capability

of caching both static and dynamically generated Web content. OracleAS Web Cache
significantly improves the performance and scalability of heavily loaded Web sites. In
addition, OracleAS Web Cache provides a number of features to ensure consistent and
predictable responses. These features include page-fragment caching, Edge Side
Includes (ESI) and Edge Side Includes for Java (JESI) support, compression, dynamic
content assembly, Web-server load balancing, Web Cache clustering, and failover.
Business Intelligence
• Using the Oracle Application Server business intelligence features, you can
dynamically serve personalized content recommendations to both registered and
anonymous visitors as they browse your site; perform dynamic, ad hoc query reporting
and analysis using a standard Web browser; and publish high-quality, dynamically
generated reports on a scalable, secure platform.
Integration
• Using Oracle Application Server, you can integrate enterprise applications, trading
partners, and Web services, and provide query and transaction access to many
non-Oracle data sources.
Availability and Scalability
• Oracle Application Server provides a flexible deployment model that you can use to
design your system for high availability and scalability.
Management and Security
• Oracle Application Server provides a set of management facilities to simplify Web site
administration. You can:
- Use Application Server Control to configure and monitor individual Oracle
Application Server instances to optimize them for performance and scalability.
When you need to use command-line interfaces, you can use dcmctl to perform
configuration management, and opmnctl to perform process management.
- Use encrypted secure sockets layer (SSL) connections, user- and client
certificate–based authentication, and single sign-on across all applications
- Implement an LDAP directory that provides a single repository and
administration environment for user accounts

Oracle Application Server: Overview (continued)
Identity Management
• Using Identity Management, you can centralize user-management tasks and manage
password policies in an enterprise setup. Identity Management is a viable solution for
secure deployment of third-party applications in an Oracle environment. These
deployments are based on integrating a secure framework between Oracle products and
multiple third-party applications. In addition, you can independently deploy Identity
Management environments in existing Oracle products, such as the Oracle database,
Oracle Collaboration Suite, and Oracle E-Business Suite.

Multitiered Model
In a multitiered architecture, Oracle Application Server 10g components reside at different
tiers or layers, which represent hardware layers, with each tier made up of one or more
servers. In general, the number of tiers and number of servers in each tier vary depending on
the Oracle Application Server 10g implementation.
The Oracle Application Server 10g architecture for a multitiered model consists of:
• Client tier: Containing the Web browsers for end users
• Web tier: Containing Oracle HTTP Server and OracleAS Web Cache
• Application server tier: Containing Oracle Application Server 10g
• Database tier: Containing the Oracle database, which can be a single instance or
multiple instances managed by Real Application Clusters (RAC)
