Oracle SOA Business rule engine [BRE]
Business rule engine [BRE]- A non – technical person can also change the business logic by wing soa computer business rules we can defined 2 ways
- Ruleset [if]
- Decision table [switch]
Tabs:
- Facts
- Functions
- Globals O.V’s (list of values) ex: 10, 20, 30, 40 -----
- Bucket set
- Links O.V’s (range of values) ex: 0-35, 35-60-----
- Decision functions A-Z, A-F ----
- Rule set
- By using BRE we can configure various business logics
- I can even configure their business logics/rules in source code it will work very well , but if there is any change in the business logic in future I will have to go back to source code, make changes completely deploy it again
- This is the process I have to do it every time when there is a change in the business logic
- Whereas by using BRE I don’t need to make changes in the source code, that is the biggest advantage
HUMAN TASK
Whenever a human interaction is required then human task is required

Remote – Fault

<composite fault policy = “handle fault”/>
</fault policyBindings>

CASE 2
---> no need to take the catch, email, terminate activities
----> concrete WSDL: (remote fault handle)
