4.4 Use case: OAM Single Sign-on ===> Oracle HTTP Server location installation webgate ===> [Access] Configure identity store (Configure an LDAP identity authenticator) OID <==== User & Role AP I provide retrieving user and group information for the application
The application needs access to the RDBMS to obtain the data, and in order to better manage the database access credentials, the credentials are created in the domain credential store.


5, Oracle SOA Suite Introduction
5.1 Oracle Service-oriented Architecture (SOA) suite products provide a platform for enterprises to adopt a unified service-oriented IT infrastructure. The infrastructure enables businesses to manage IT services more efficiently and flexibly, and to create new value-added services more efficiently.
The core components of the 5.1.1 SOA suite are the SOA infrastructure, Business Activity Monitoring (BAM), and the User messaging Service (UMS).
5.2 SOA infrastructure components are comprised of an environment-based service component Architecture (Services Component Architecture SCA), including business Process Execution Language (BPEL), Business process Modeling notation (BPMN), mediation, user tasks, business rules, Spring Serviced components.
5.2.1 Service Component Architecture, SCA, a component is a module that encapsulates all of the semantic-related logic and provides an explicit interface that contains all the information that external entities have access to internal functionality. SCA is a specification used to define a metadata-driven model (XML) that describes a software application consisting of loosely coupled components, each of which can be implemented by different technologies.
5.2.2, the so-called combination of SCA, all application business logic developed for the SOA infrastructure exists in the form of an SCA combination.
5.2.3 Deployment Mix: The SOA mix is packaged into a jar file called the SOA archive, the SAR, for deployment to the SOA server. In order to deploy the SAR file in the SOA server, you can use the Jdeveloper,em, Wlst command. The SOA Suite portfolio is deployed directly in the SOA infrastructure container, not by using WebLogic Server.
5.2.4 Combined Services and references, a deployed combination can expose its services to enable external entities to use their functionality. A combination can also depend on services that are exposed by external entities. Available SOA Suite services, Web services, HTTP services, ADF BC Services, Java Connector Framework (JCA), EJB, direct service (dedicated Oracle interface).
5.3 Oracle Business Activity Monitoring (BAM): A component of the SOA suite that captures data from runtime applications and their processing, aggregates, and renders as real-time business reports.
5.3.1 Oracle BAM Data Objects are data structures defined by technical users through the [Oracle BAM Architect Web application] to identify application information that needs to be collected and presented to business users. Once the Oracle BAM object is defined, the business user is able to define the report using [Oracle BAM Active Studio Web application], which is a Web page, and once the report is defined, other business users can go through the [Oracle BAM Active V Iewer WEB application] to view report results.
The 5.3.2 Oracle BAM functionality is split into two tiers: the Oracle BAM Server tier and the Oracle BAM Web tier.
The 5.3.3 Oracle BAM server tier contains all the components that are used to gather information from different sources and map this information to specific data objects. Information update requests that are mapped to data objects are sent by an external source as an Oracle BAM command to the Oracle BAM server.
5.3.4 Oracle BAM Web: Contains a collection of Web applications, including Oracle BAM active Studio, Oracle BAM active Viewer, Oracle BAM Architect, Oracle BAM Administrator.
5.4 User Message Service (UMS): Through UMS, applications can interact directly with end users using different types of message protocols. The UMS consists of two main components: the UMS server and the UMS driver. The UMS server provides interaction between the Java EE program and the corresponding application, as well as the UMS driver. UMS drivers include instant messaging, Email, voicemail,sms, and SOA Suite human Task worklist.
5.5 Use case: ERP system ====> update message file ===> worklist ===> [UPDATE request command] ===> Oracle BAM Server ====> user Terminal application
