Oracle SOA Governance 11g Implementation

Overview of this book

Service-oriented Architecture (SOA) is an architectural style created to address the challenges posed by today’s highly distributed, fast-paced computing. This goal is achieved by constructing business-focused software systems from loosely coupled, interoperable building blocks called Services. Organizations often fail to successfully implement SOA due to a lack of effective governance. Oracle SOA Governance is a comprehensive, service-orientated architecture governance solution that is designed to make the transition to SOA easier."Oracle SOA Governance 11g Implementation" illustrates how to successfully implement SOA governance in your organization. To achieve this, we describe how goals and objectives need to be clearly laid out and used to align governance processes with governance tools, governance tools with people, and people with the different roles and responsibilities that are required to implement effective governance."Oracle SOA Governance 11g Implementation" begins with a short but concise overview of SOA governance. We then go to explore real world examples, based on previous experiences and working solutions, in order to learn the concepts of Oracle SOA Governance Suite.We will also learn how to implement an OER-centric SDLC process to address your organizations design-time governance requirements. Next, we will explore OSR, and discover how to use it to expose service implementations to consumers based on UDDI concepts. We will explore the features available within Web Service Manager (WSM), Oracle Enterprise Manager (OEM), and Business Transaction Manager (BTM). Finally, we discover how OER can be extended to govern Oracle Application Integration Architecture (AIA) implementations.Discover and learn how to use Oracle SOA Governance Suite to address your specific design-time and runtime governance challenges.

Implementing Policies


Assets compliance requirements can be enforced in OER with the utilization of Policies. Policies can be applied to one or many Assets. An Asset can have more than one policy attached to it. A policy in OER consists of one-to-many Policy Assertions. When a policy is applied to an Asset, all of the assertions within the policy must be true in order for Asset to comply with the policy.

Each assertion has a name, a description, and includes a technical definition. Technical definitions support additional metadata that may be needed to validate the assertion (for example, a particular Asset must have less than 1 percent defects before the service can be deployed to the next environment).

According to the use case the following Policies are needed in to order to support the target governance model:

Note that for your organization, you may define as many Policies as you required. For the purposes of this chapter we simplified it.
