QuestionQ2

VerifiedTroubleshooting and Maintenance

You are responsible for tuning the application environment for Oracle Java Cloud Service.

Identify the proper sequence of activities in Oracle’s recommended performance-tuning methodology.

QuestionQ3

VerifiedProvisioning and Monitoring Java Cloud Service Instances

You created a Database Cloud Service instance and are now trying to create an Oracle Java Cloud Service instance. However, when you arrive at the main Oracle Java Cloud Service configuration screen, your database instance is unavailable for selection, preventing creation of the JCS instance.

You verify that the database instance is running. What is preventing creation of the Oracle Java Cloud Service instance?

Explanation

For Oracle Java Cloud Service provisioning, the Database Cloud Service deployment must be configured for automatic backups using both cloud and local storage in order to be eligible for selection. A database created without that backup-storage configuration is not presented by the provisioning wizard even when it is running.

QuestionQ4

VerifiedProvisioning and Monitoring Java Cloud Service Instances

You created an Oracle Java Cloud Service instance and want to use the capabilities of Node Manager.

Which two statements about using Node Manager in Oracle Java Cloud Service are true?

Choose two
Explanation

Oracle WebLogic Server Node Manager can be accessed through the WebLogic Server Administration Console and is used to start, shut down, and restart Administration Server and Managed Server instances. VM lifecycle operations are managed separately from Node Manager, and Node Manager does not perform server migration to a different machine after a machine failure.

QuestionQ5

VerifiedProvisioning and Monitoring Java Cloud Service Instances

You are reviewing the service metrics available in the Oracle Java Cloud Service console.

Which three metrics are available in this console?

Choose three
Explanation

Oracle Java Cloud Service exposes runtime health and performance metrics for its WebLogic Server environment, including JVM heap utilization, JDBC connection usage, and JVM garbage-collection timing. OCPU-hour consumption and GB-per-month storage consumption are billing or resource-usage measures, not these service metrics.
