WebLogic is a complex, professional application server environment with a complex and powerful security environment. WebLogic server at its core implements the J2EE specification stack and its main purpose is to offer a hosting environment for J2EE applications. But WebLogic is much more than that. Like most professional J2EE server WebLogic also offers a large number of extended features like comprehensive management, clustering and failover functionality on different levels, plus a number of extended enterprise features not required by J2EE but very useful in the enterprise world, enterprise features that are required by many companies.

All production environments need automated, auditable, and reproducible processes. This book discusses how to automate all aspects of WebLogic, an essential prerequisite for all production environments. The WebLogic Server platform is recognized as one of the leading J2EE application servers and is the foundation of the Fusion Middleware platform. It is well suited for a variety of different application architectures including modern grid and cloud infrastructures. A large number of WebLogic installations from a single server to thousands of servers exist all over the world. Complex environments may consist of hundreds of domains and thousands of managed-servers. It is impossible for an administrator group to maintain all those servers with manual tasks or the web console. This book is written based on 15+ years of experience with many real architecture and consultancy assignments, and includes tips based on lessons learned from real project experience. Its main focus is to teach readers who are already familiar with WebLogic how to use the powerful automation APIs to operate WebLogic in small to very complex environments. This book includes many practical examples that can be easily adapted to the reader's needs. This book does not use the WebLogic GUI nor talk about J2EE programming; it focuses on automation only. A comprehensive code download of powerful WLST and JMX scripts is also provided.

With WebLogic 12.2.x a complete new concept - called partition - was introduced into WebLogic in order to support multitenancy setups and concepts. This new technology can also serve as a solid foundation for cloud services and cloud hosting. A partition is - similar to a filesystem partition - meant to be a well-defined area of WebLogic, with some new and powerful features. Other than the standard J2EE bundling units like EAR, WAR or RAR archives, the partition goes beyond that and allows a bundling of applications (J2EE units) and required resources like JDBC, JMS and more into a single "WebLogic application" based on the partition technology. Partitions can also be exported, migrated and imported as a single unit. Many real world use-cases can benefit significantly from the new multitenancy technology. This book explains the new WebLogic technologies in detail. In addition to the technology deep-dives, this book discusses many use-cases found daily in our industry and shows the potential benefit of multitenancy technologies for these scenarios. Key Features: Overview and deep-dives into the new WebLogic technologies around multitenancy Many examples using WLST scripting in order to automate partition handling All scripts and programs can easily be adapted to the reader's need Discussion of a number of real-world uses and how these could benefit from multitenancy Focus on architects, decision-makers, administrators and developers
