3. What is a Process in IBM BPM ?

Ans: A process is like a Program that does work inside teamwork. It has a starting point and at least one exit point.

5.What are Variables(Business Objects) in IBM BPM?

Ans: Business objects are called variables in Teamworks represent the data that provides the data that provides the business context to a running process.

There are two types of variables 

• Simple And Complex variables have different scopes
• private Input and Output.

6.In production one instance has been failed due to some business object has bad data or null values, How will you inject data on runtime in production?

Ans: IBPM provide some rest api which operation name is setData through that we can inject values.

7.I have one BPD, which has multiple tasks. How will you identify user in run-time and assign the task based on his role?

Ans: Its related to routing.

8.How will you start BPM from out side?

Ans: There are 4 ways:

1. Expose as a webservice like WSDL and call it from outside and inside the BPM call in javascript 'startBPMByProcessName()'.
2. BPM API expose as rest service to start the BPM process.
3. Through JMS, we can start bpm process.
4. Through Java api we can start the bpm process.

9.What is the difference between process app and toolkit?

Ans: Process App is deployable but toolkit is not deployable it should be integrate

Breaking IBPM down into these constituent components both aids in the understanding of the product as well as providing a practical differentiation between phases and pieces of operation.

1. Process Server
2. Process Designer
3. Process Center
4. Performance Data Warehouse
5. Process Center Console
6. Process Portal
7. Process Admin Console

16.What is Durable Subscription?

Ans: When a message is sent to an user who is offline, the message waits in the queue and gets delivered when the user appears online again. This phenomenon is called as "Durable Subscription".
