IBM WebSphere Operational Decision Management V8.0 Application Development Sample Questions:

1. An application developer just activated Decision Warehouse for a ruleset deployed to Rule Execution Server. The ruleset has a Business Object Model (BOM) class com.test.Customer with two large properties: Customer.largeString1 and Customer.largeString2. Activating Decision Warehouse resulted in a decrease in ruleset execution performance. How can the application developer reduce the BOM serialization performance impact and retain the ability to search input and output parameters on the Decision Warehouse tab of the Rule Execution Server Console?

A) Set the ruleset.bom.enabled property to false and in Customer.toString() return a value containing Customer.largeString1 and Customer.largeString2
B) Set the monitoring.inout.filters property to Customer.largeString1,Customer.largeString2.
C) Set the monitoring.filters property to Customer.largeString1,Customer.largeString2.
D) Set the monitoring.inout.filters property to INFO_WORKING_MEMORY=true,WORKING_MEMORY_FILTER=com.test.Customer.

2. Business users manage promotions within Decision Center. To manage the promotions within Decision Center, the user interface needs to be customized with a new Promotion tab on the top menu. What should an application developer to do to register the Promotion tab?

How should the application developer create the ruleflows?

A) Create 2 ruleflows and set the main flow task property of each ruleflow to true.
B) Create 4 ruleflows, set the main flow task property of the main ruleflow to the name of the decision service and for each other ruleflow set it to the label of relevant rule task.
C) Create 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.
