Oracle 1z1-133 : Oracle WebLogic Server 12c: Administration I

Your developers created Plain Old Java Objects (POJO) that provide useful functionality. The code is packaged in a JAR file. You want to make this code accessible from all the applications deployed to the managed servers in your domain. What are the four ways to accomplish this? (Choose four.)

• A. Deploy the JAR file as an EJB
• B. Add the JAR file to the CLASSPATH of the domain servers by editing the domain's seyDomainEnv.sh script
• C. Deploy the JAR file to the administration server. All managed servers have access to their admin server
• D. Deploy the JAR file as a web service.
• E. Place the JAR file in the lib folder of the domain
• F. Deploy the JAR file as another web application
• G. Deploy the JAR file as a shared library
• H. Include the JAR file as an optional package

You are creating and configuring a cluster by using the administration console. Which two statements are true?
(Choose two.)

• A. The administration console does not provide a way to manually migrate singleton services. It must be set up to be done automatically or by using WLST.
• B. All servers that will be part of the cluster must be created before the cluster is created.
• C. You must pick the cluster messaging mode.
• D. Even though you create a non-dynamic cluster, you can change it to a dynamic cluster later.
• E. Once the cluster is created, you cannot change its messaging mode.

You want to configure WebLogic Server transactions to be recoverable when a nonclustered managed server crashes, even if that crash is caused by an unrecoverable hardware failure. You want to run the managed server on different hardware, and have it recover the transactions that were in-progress at the time of the crash.
You also want to use the default store for transaction logs.
Which statement is true?

• A. This scenario is common, and so the default configuration of the default store works.
• B. Before the crash, you need to update the path to the default store for the managed server. The path should be to some shared storage location.
• C. This scenario is not possible. You must use the JDBC store to recover transactions from a crashed server.
• D. After the crash, obtain a copy of the managed server's default store from the administration server.
  Move it to the same relative location on the new hardware before starting the managed server there.
• E. This scenario is not possible. You must use clustered managed servers to recover transactions from a crashed server.

Your domain consists of 30 servers. You are using the Administration Console.
Which is the quickest way to identify the servers that are in a Failed health state?

• A. Use the Filter button from the domain's Monitoring > Health tab.
• B. Write a custom WLST script to print out failed server.
• C. Use the Monitoring > Health tab for each server in the domain.
• D. Capture a diagnostic snapshot.

As part of troubleshooting an application, you need to analyze the HTTP session count and the server heap size over the past six hours. You are using the Administration Console. You want to view both metrics together and correlate their values.
Which three steps should you take in the Administration Console? (Choose three.)

• A. Create a custom view.
• B. Drag each metric onto two charts in the same view.
• C. Start the JVM Runtime view.
• D. Click the application's Monitoring tab.
• E. Access the Monitoring Dashboard.
