Lesson 5 Web Request Broker Cartridges
ObjectiveDescribe the function of Web Request Broker Cartridges
Question: Have Oracle Web Request Broker Cartridges been deprecated?
Yes, Oracle Web Request Broker Cartridges were deprecated in Oracle WebLogic Server 12c Release 2 (12.2.1.4). Oracle recommends that users migrate to alternative technologies, such as Oracle Integration Cloud Service or Oracle Integration Platform Cloud Service.
Oracle Web Request Broker Cartridges were used to extend the functionality of Oracle WebLogic Server by providing integration with external systems and services. However, these cartridges have been superseded by newer and more powerful technologies.
If you are still using Oracle Web Request Broker Cartridges, you should plan to migrate to a newer technology as soon as possible. Oracle will no longer provide support for Oracle Web Request Broker Cartridges after Oracle WebLogic Server 12c Release 2 (12.2.1.4).
Here are some alternative technologies that you may want to consider:
  1. Oracle Integration Cloud Service: A cloud-based integration platform that provides a wide range of features for connecting and integrating applications and data.
  2. Oracle Integration Platform Cloud Service: A cloud-based integration platform that provides a more flexible and scalable solution for complex integration needs.

Web Request Broker and Cartridges

The following series of images describe the role and function of the last two Web Architecture components:
  1. the Web Request Broker (WRB) and
  2. the Web cartridges.

The Web Request Broker (WRB) handles Web requests for Oracle data.
Internally, the Web Request Broker consists of a dispatcher.

Note: Oracle has published the specifications for their plug-ins so that numerous third-party vendors can create new cartridges to access Oracle WebServer. In addition, the Web Request Broker API is published, so third-party vendors can write additional cartridges for the Oracle Web Request Broker.
