In a production environment, a system administrator tuned the data source statement cache to optimize the processing of prepared statements and callable statements by caching those statements that are not used in an active connection. When the cache is full, old entries in the cache are discarded. The administrator would like to get statistics on the number of statements discarded from the cache to determine how to minimizecache discards. How can the system administrator obtain this information?

• A. Enable request metrics.
• B. Configure HPEL and examine the log files.
• C. Use the IBM Support Assistant Data Collector.
• D. Use the Tivoli Performance Viewer.

A system administrator has just built a WebSphere Application Server node to replace a node lost to disk failure. The system administrator wishes to reincorporate this node into the existing WebSphere Application Server cell and use the prior configuration information. Unfortunately, the backup of the cell is extremely out of date. What should the system administrator use to accomplish this task?

• A. manageprofiles

A system administrator is asked to increase the logging level of an e-commerce application running on a production server to help developers troubleshoot a problem that is difficult to reproduce. The requester wants lengthy comprehensive logs to locate the root cause of the problem. The application is responsible for the online shopping experience of thousands of customers daily.

• C. Enable the diagnostic trace service in-memory circular buffer.
• D. Enable Cross Component Tracing.

A system administrator is using wsadmin scripts to perform product configuration.
The command connects to a target server by specifying the connection type (SOAP), target server, port number and script file. The scripts have been successfully tested in a standalone environment. But, after the node is federated, the updates made are only visible for a limited amount of time. What should the system administrator do to fix this problem?

• A. Verify that deployment manager is set as the target server.
• B. Ensure that the deployment manager and node agents are synchronized before running the script.
• C. wsadmin should target node agent.
• D. After running wsadmin, a syncNode command should be run.

An administrator needs to move an application from a Liberty profile development environment to a production Network Deployment cell. What steps should the administrator take to deploy the application in the production cell?

• A. Use the "Release" functionality in the administrative console and point it to the server.xml file of the development Liberty profile.
• B. Deploy the application EAR file through the deployment manager and define the resources defined in the server.xml.
• C. Use the migration tool to generate the customizedand automated wsadmin script.
• D. Use the enhanced EAR generated by the Liberty profile ensuring that the resources used by the Liberty profile are used by the deployment manager.
