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

1. An application developer is validating a rule project in Rule Designer and needs to create a new DVS Excel File Run Configuration. Instead of testing all of the rules, the new run configuration must also specify a subset of the rules to test. Which setting in the run configuration must the application developer apply?

A) On the Rules tab, specify the rules to test.
B) On the Excel File tab, specify the rules to test.
C) On the Extraction tab, select to use an extractor which specifies the rules to test.
D) On the Excel File tab, click Browse next to Rule Project and specify the rules to test.

2. A company implemented a report data validation system with business rules. As there is a large volume of data, the design team has decided to run validations in batch and parallel mode. The ruleset will be executed in Java SE and the maximum number of threads executing rules is 20). When an application developer tests the rule execution code, the following exception comes up: ilog.rules.res.session.IlrSessionException: An error occurred while the rule session was called: ilog.rules.res.xu.cmanager.impl.IlrLocalizedResourceAllocationException: Default connection manager pool is full, error code: GBRXU0200E ilog.rules.res.xu.pool.IlrPoolException: Pool of connections is full What should the application developer do to resolve the exception?

A) Set pool size of the Execution Unit (XU) connection factory in the application server to 20.
B) Set the ruleset property pool.maxSize to 20.
C) Configure the IlrSessionRequest class to set connection pool size to 20.
D) Edit the resource adapter descriptor file ra.xml to set the pool.maxSize property to 20.

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

4. After a company deploys their rules to production, a series of new business policies affect several of the deployed rules. The rule authors fix the rules, and the updated ruleset is deployed.
However, another business policy change makes some of the rule fixes incorrect and the original rules need to be reinstated. The rule authors ask for help from the application developer so that they do not lose their correct changes. What should the application developer do?

A) Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.
B) Restore the baseline so that it becomes the current state of the project so that the rule authors redo the appropriate rule changes.
C) Clone the deployment baseline to a branch, and use the Diff and Merge tool to select the correct rules to keep on the current branch of the project.
D) Erase the current project and synchronize with Rule Designer to get the originally deployed rules.

5. An application developer is required to implement the following business policy represented by this pseudo code which has a set of non-symmetrical rules.
