You create a new Work Manager to control how server threads are allocated to an application’s incoming requests. You want to further configure the criteria of the Work Manager by using a Request Class.
Identify three valid Request Classes that you can assign to a Work Manager. (Choose three.)
Which two metrics are used to monitor and troubleshoot unicast communication in a cluster? (Choose two.)
You are responsible for configuring a WebLogic domain to support an order processing application. This application will communicate with multiple JDBC data sources to fulfill each customer order. To maintain data integrity across these databases, work will be performed within a global transaction. However, you have learned that one of the data sources in the transaction does not have an XA driver.
Which option should you select on this non-XA data source to ensure that orders are still processed as global transactions?
The Administration Server of a domain fails due to a hardware failure. The hardware is beyond repair.
Before the failure you prepared a “backup admin server”. You go through your planned recovery process and are successful. The Administration Server is now running on different hardware. The managed servers of the domain automatically reconnect to the admin server.
Select the two statements that are true. (Choose two.)
Which three runtime metrics can you monitor or collect from WebLogic Server applications? (Choose three.)
During a performance test, a server’s log includes several OutOfMemoryError messages. You are using the Administration Console.
How can you verify the amount of available heap in the server?
Select two true statements about WebLogic Server’s role in transaction management. (Choose two.)
Consider a multiple node domain. On the administration server’s node, you edit setDomainEnv.sh in the bin directory and add a new JAR file to the CLASSPATH. You stop and restart all three WebLogic Server in the domain. Upon investigation, you discover that only applications deployed to one WebLogic Server are able to access the JAR file code. How do you explain this?
While using the Configuration Wizard to create a new domain, you do not set the Listen Address for the administration server and accept the default value. What is the result?
Before you view JVM performance information in the administration console, you want to request that the JVM do a garbage collection.
How can you do this in the admin console?
An application fails. The exception indicates that the JDBC data source cannot be found.
Identify two possible steps that you can perform to verify the data source’s availability. (Choose two.)
You created a shutdown class MyClass that you would like to execute just before server shutdown.
Which statement is true regarding MyClass?
Select two ways to start the Java-based Node Manager on a Linux machine. (Choose two.)
You create a new Managed Server in your domain by using the administration console. You give it the listen address of 192.0.2.0 and the listen port of 7100.You save and activate the changes.
You use the domain start script to start the new server. It fails. One of the messages in the window in which you can ran the script is:
Server failed to bind to any usable port.
You investigate and see that another process is running on 192.0.2.0 on port 7100.You also find many unused ports at that IP address.
Which two statements are true? (Choose two.)
You need to scale out an existing domain to include a new machine. You install WebLogic Server on the new machine. Which three steps are required to create the domain directory on the new machine? (Choose three.)
You zipped up the domain’s config directory on the administration server’s machine before making some major configuration changes. You wait to activate after all the changes have been saved. After your changes are in, things start failing badly. You want to go back to the old configuration.
