Key Differences between Application Developer 11g and Infrastructure 12c

Key Differences between Application Developer 11g and Infrastructure 12c

Oracle Fusion Middleware Infrastructure 12c is similar to the 11g Application Developer installation, except for the following differences:

·         Infrastructure 12c Includes Oracle WebLogic Server

·         Infrastructure 12c Requires Specific Database Schemas

·         Infrastructure 12c Domains Can Include Oracle HTTP Server

Infrastructure 12c Includes Oracle WebLogic Server

The Application Developer 11g installation required two separate installations (Oracle WebLogic Server and then Application Developer to add the Oracle JRF libraries and components). In Oracle Fusion Middleware 12c, a fresh installation requires only the Oracle Fusion Middleware Infrastructure distribution, which contains both Oracle WebLogic Server and the required Java Required Files technologies.

Note that the upgrade procedure does not require the configuration of a new Oracle Fusion Middleware 12c domain. Instead, you use the Reconfiguration Wizard to upgrade the domain.

Infrastructure 12c Requires Specific Database Schemas

Unlike the Application Developer 11g installation, the Infrastructure 12c installation requires that you create a set of required schemas in a supported database. In particular, you must use the 12c Repository Creation Utility (RCU) to create at least one required database schema before you can configure the Oracle Fusion Middleware Infrastructure 12c (12.1.2) software.

Depending upon your requirements, you must install one or more of the following database schemas before you can upgrade to Oracle Fusion Middleware Infrastructure 12c (12.1.2):

• The Service Table (STB) schema, which is a new schema required for all Oracle Fusion Middleware Infrastructure 12c installations. This schema enables a new Oracle Fusion Middleware 12c feature called Cross-Component Wiring.
• The OPSS schema, which provides a database-based security store for Oracle Platform Security Services.

You might be required to create the OPSS 12c (12.1.2) schema, depending upon whether or not you are using a security store in 11g and the type of security you are using.

• The IAU schema, which is used for the OPSS auditing capabilities.

You might be required to create the IAU 12c (12.1.2) schema, depending up whether or not you are using an Audit Data Store in 11g and the type of Audit Data Store you are using.

 Infrastructure 12c Domains Can Include Oracle HTTP Server

In Oracle Fusion Middleware 11g, Oracle HTTP Server instances are typically configured in a separate Oracle instance directory outside the 11gMiddleware home. Oracle HTTP Server 11g instances are managed using the Oracle Process Manager and Notification Server (OPMN) management software. Optionally, the Oracle HTTP Server 11g instances can be "associated with" the WebLogic domain.

In Oracle Fusion Middleware 12c, Oracle HTTP Server instances can be configured a part of an Oracle WebLogic Server domain, using the Oracle Fusion Middleware Configuration Wizard. When configured as part of an Oracle Fusion Middleware Infrastructure domain, Oracle HTTP Server instances can be managed using Oracle Enterprise Manager Fusion Middleware Control and the Oracle Weblogic Scripting Tool (WLST). In Oracle Fusion Middleware 12c, the Node Manager agent is responsible for delegating and executing management requests to OHS instances"
