Fusion 11g - A Foundation for Innovation

By Naveen Chadra

Recently, Oracle has unveiled Fusion Middleware 11g, which is a one stop shop for all IT needs.

Fusion Middleware 11g is built on four unique design principles:


There are many significant new capabilities and enhancements in the key product areas of the Oracle Fusion Middleware 11g release that will serve as a foundation for innovation. Oracle Fusion Middleware 11g supports new single sign-on solutions that applications can use to establish and enforce perimeter authentication:

Comparison of Typical Oracle Single Sign-On Topologies in Oracle Application Server 10g and Oracle Fusion Middleware 11g

Existing OSSO 10g Customers: Oracle Single Sign-On is part of the 10g Oracle Application Server suite. OSSO is an enterprise-level single sign-on solution that works in conjunction with Oracle Internet Directory and Oracle HTTP Server 11g. If OSSO is already in place as the enterprise solution for your existing Oracle deployment, Oracle Fusion Middleware continues to support the existing OSSO as a solution.

Oracle Access Manager Integration with OSSO: If applications (Oracle Portal for example) are deployed that previously required OracleAS Single Sign-On, you can delegate the authentication (from OSSO 10g) to Oracle Access Manager 11g. Oracle Internet Directory is needed for applications that require integrating Oracle Access Manager and OSSO.

Windows Native Authentication for Microsoft Clients: OSSO and Oracle Access Manager 11g both support this integration. Oracle WebLogic Server can be configured to use the Simple and Protected Negotiate (SPNEGO) mechanism for authentication to provide Windows Native Authentication support.

Portal, Forms, Reports, and Discoverer 11g: In 10g these components relied on Oracle Single Sign-On as the SSO solution, and they continue to do so in 11g. OSSO 10g, along with Oracle Delegated Administration Services 10g, are mandatory for these components. Oracle Internet Directory 10g or 11g are also mandatory for these components.

MultiMaster Replication: As of 11g Release 1 (11.1.1), LDAP-based replication can be used for multimaster replication as well as one-way and two-way replication. As a result, Oracle Database Advanced Replication-based replication is less important than it was in 10g ( The only time you must use Advanced Replication in 11g Release 1 (11.1.1) is when you have ­Oracle Single Sign-On configured on the same machine and you want to replicate Oracle Single Sign-On data as well as Oracle Internet Directory data.

In conclusion, I would like to leave you with an interesting snippet of information given above and referring to Fusion 11g related documentation. It highlights how Fusion11g offers the efficiency of working with a single, strategic partner for all of your middleware requirements (SOA,IDM,OVD,Agile etc.), as well as the cost effectiveness of certified integrations with Oracle Database, Oracle Applications, and Oracle Engineered Systems.

Oracle Fusion Middleware provides a leading business innovation platform for a complete, open and integrated approach across social, mobile and cloud technologies. Based on its design principles, Oracle Fusion 11g middleware is basically a one stop shop for all your IT needs and it allows us to design tightly integrated advanced architecture and implement enterprise level systems for our customers. This technology brings everything together - highly-scalable and highly-available standard enterprise integration patterns, robust frameworks and reliable security. Developers can use sets of pre-developed, reusable components, this improves development quality and helps to speed up implementation process.
