IBM Assessment: IBM WebSphere Operational Decision Management V8.0, Application Development 認定 A2180-400 試験問題：

問題 #1

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. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
B. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
C. Make sure the cache is empty before the first ruleset is parsed.
D. 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.

問題 #2

An application developer is in charge of synchronizing changes in a rule project between Decision Center and the Source Code Control (SCC) tool used for development. Which rule project artifacts should the application developer exclude from SCC?

A. resources and templates folders
B. resources folder and .syncEntries file
C. output, templates and queries folders
D. output folder and .syncEntries file

問題 #3

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. Edit the resource adapter descriptor file ra.xml to set the pool.maxSize property to 20.
D. Configure the IlrSessionRequest class to set connection pool size to 20.

問題 #4

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?

B. Add a teamserver:tab tag to /custom/tabs.jsp.
C. Add the tab to the /WEB-INF/teamserver.tld file.
D. Register the tab through modifying the Decision Center configuration parameters in the application server.

問題 #5

A ruleset is deployed to Rule Execution Server and the rule administrators requested that Decision Warehouse be used to store trace information about ruleset executions. What should the application developer do to activate tracing on the already deployed ruleset?

A. Use the res-deploy Ant task with the correct parameters to enable tracing on the deployed ruleset.
B. Navigate to the ruleset within Rule Execution Server console and click the Show Monitoring Options to enable tracing.
C. Tracing cannot be enabled without deploying the ruleset again with the monitoring.enabled ruleset property set to true.
D. Navigate to the ruleset within Rule Execution Server console and add the ruleset.trace.enabled property.
