Learning the recent changes released on weblogic server is very important. When you take weblogic online training, its important to take this from a well reputed institute and verify their expertise and trainers before join the course. Check out some interview questions here.

  1. Docker Support

Oracle WebLogic Server 12.1.3 is now certified to run inside a Docker container. Docker is a Linux-based container technology that enables you to quickly create lightweight clustered and non-clustered WebLogic Server domain configurations on a single host OS or virtual machines, for either development or production environments.

As part of this certification, Oracle provides Docker files and supporting scripts for building images of Oracle WebLogic Server. These images are built as an extension of existing Oracle Linux images. These scripts and build images are available on GitHub at the following location:

2) Oracle Fusion Middleware 12.1.3 Support

WebLogic Server 12.1.3 is integrated with other Oracle Fusion Middleware 12.1.3 products. Oracle Fusion Middleware is a comprehensive family of products ranging from application development tools and integration solutions to identity management, collaboration, and business intelligence reporting. For more information, see the Oracle Fusion Middleware 12.1.3 documentation library page at

3) New APIs and Tools for Application Development

WebLogic Server 12.1.3 provides support for selected new or updated APIs from Java EE 7, such as JAX-RS 2.0, Java API for JSON Processing (JSR 353), Java API for WebSocket (JSR 356), and JPA 2.1. These APIs and related capabilities simplify development of server applications accessed by “rich” clients using lightweight web-based protocols such as REST, WebSocket, and Server-Sent Events. Improvements to development tooling and open source support expand developer choices and simplify creation of development environments.

4) Runtime Improvements

WebLogic Server 12.1.3 builds on support from prior WebLogic Server versions to improve the reliability, availability, scalability and performance of WebLogic Server applications in clustered environments, when using new Oracle database features, in multi data center architectures, and on Exalogic Systems.

5) Manageability Improvements

WebLogic Server 12.1.3 continues to provide new management features which simplify the configuration, monitoring and ongoing management of WebLogic Server domains and applications. These new features are described in the following sections:

REST Resources for Server Management

Fusion Middleware Control

Global Policy Attachment Support


Logging Enhancements
