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

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. Configure the IlrSessionRequest class to set connection pool size to 20.
- B. Edit the resource adapter descriptor file ra.xml to set the pool.maxSize property to 20.
- C. Set pool size of the Execution Unit (XU) connection factory in the application server to 20.
- D. Set the ruleset property pool.maxSize to 20.
The design team decided to populate a Business Object Model (BOM) domain from a database and allow the rule authors to reload domain values within Decision Center when the database is updated. What should an application developer do to implement these requirements?

A company is running 20,000 rules in one ruleset and experiences latency during some ruleset executions. No hot deployments are used. After reviewing the execution traces, the application developer recognizes that the performance is affected by reparsing of the same ruleset after overnight inactivity. What should the application developer do to minimize the impact of ruleset parsing and speed up performance?
- A. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
- B. Make sure the cache is empty before the first ruleset is parsed.
- C. In the ra.xml file, set the pool.maxSize parameter to make sure that the number of active rulesets is greater than the size of the XU connection pool.
