07 Oracle BPM11g Workshop - Implementation

BPMN User Task
• Refers to a step that is managed by the workflow engine. • Performer(s) – participants for the User Task. The associated Task (work to be performed) is shown in the inbox of the assigned performers when the User Task is triggered. The actual work is performed only when the Performer executes on his Task. • Representation (Forms) – The data required for the work to be done. Also referred to as User Interfaces. Can be a single html page or a page flow. • Owner – person who can re-route or carry out the task in case of escalation, exception kinds of scenarios. • Refers to BPEL4People for task implementation semantics. The Task definition can either be in-line or executed as a Service outside the core process execution engine.

BPMN服务任务（Service Task ） 服务任务
• Service Task
• 指系统调用或自动步骤 • BPMN假定该任务的业务功能 以服务或操作方式暴露出来 • 调用是同步方式的，当获得返 回响应时完成 • 该流程步骤的输入和输出会映 射到具体操作的输入和输出消 息
Human Workflow
Business Rules
Mediator
Unified SCA Based Runtime • Extract business rules from processes and procedural logic • Express business rules declaratively and execute in an inference capable business rules engine • User Interfaces lets business users define business rules
• You can either look-up (task services get added to the Business Catalog) or create a new Task Service. • Multiple User Tasks can share the same Task Service.

BPM Studio – 零代码的开发环境
BPM和SOA 之间统一的服务基础 和
This figure shows the BPM Composite Model inside BPM Studio
• Shared SOA Services - Oracle BPM 11g is based of a unified architecture and shares the same set of Task Services, Decision (Rule-based) Services, Adapter Services with the Oracle SOA 11g product. • Zero-code IT Environment - BPM Studio is unified with JDeveloper and SOA tooling providing IT users the same set of zero-code capabilities, including adapters, events, transformations, rules, etc.
• • • • • • • • Business Policies – e.g. Spending Policies, Approval Matrices. Constraints – e.g. Valid configurations, regulatory requirements Computations – e.g. Discounts, Premiums, Scores Reasoning Capabilities – e.g. Offers based on customer value Rules are easier to change Agility Rules are more responsive Agility Rules are accessible Transparency Rules are consistently applied Transparency
• BPEL Processes, Adapter Services are created in the “SOA” or “Applications Navigator” view. They then become visible in the Business Catalog in the “BPM Navigator” view. • Human Task and Business Rules Services are specialized Services and can only be linked to User Task and Rules Task respectively. •

• Task Service Wizard
• Title - refers to the header of the task when it is presented to the performer in the worklist. • Pattern – Refers to User Task extensions based on workflow patterns.
规则任务（ 规则任务（Rule Task ）
• BPMN规则任务
• 对规则定义的引用
• Oracle BPM Studio
• You can link Rule Definitions to a Rule Task in one of the 2 ways. Go to Implementation Tab. • Browse (…) a Rule Definition from the Business Catalog. • Create (+) a Rule Definition by invoking the Rules Editor. The Rule Definition gets automatically added to the Business Catalog.

• Drag & Drop an Adapter Service from the Service Component Palette to the Composite Diagram. • Follow the configuration steps in the Adapter Service wizard. • The Adapter Service now gets added to the Business Catalog/Services folder.
• You can override certain parameters of the Task Service in the User Task
- Title, Priority
• Pattern - User Task extensions based on supported workflow patterns by the Oracle Task Engine. (More on this in the next slide)
