Which two statements are true about the role of cluster master in whole server migration? (Choose two.)

  1. There is exactly one cluster master in the cluster at a given point of time.
  2. The cluster master must host all the pinned services in the cluster.
  3. Any managed server in the cluster can serve as the cluster master.
  4. A cluster master must always be different from a singleton master.
  5. The cluster master must always be started with the node manager.

Answer(s): A,C

Explanation:

One server instance in a cluster that contains migratable servers acts as the cluster master and orchestrates the process of automatic server migration, in the event of failure.
Any Managed Server in a cluster can serve as the cluster master, whether it hosts pinned services or not.
Note: Any server instance in the cluster can serve as the cluster master. When you start a cluster that contains migratable servers, the first server to join the cluster becomes the cluster master and starts up the cluster manager service. If a cluster does not include at least one migratable server, it does not require a cluster master, and the cluster master service does not start up.

You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.
Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)

  1. AUTO_ACKNOWLEDGE
  2. CLIENT_ACKNOWLEDGE
  3. DUPS_OK_ACKNOWLEDGE
  4. DEFAULT_ACKNOWLEDGE

Answer(s): B

Explanation:

With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge.
Incorrect Answers:
A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.
C: With DUPS_OK_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it; duplicate acknowledges are permitted.
D: There is no acknowledge mode named DEFAULT_ACKNOWLEDGE.

You created a script to monitor your WebLogic Server WLS Execute Thread:



Here is a message in your ExecuteThread.log file:


What is the value of xxxx if the thread has been running a request for twenty minutes, assuming a default configuration?

  1. SRANDBY
  2. ACTIVE
  3. STUCK
  4. RUNNING
  5. WAITING
  6. ADMIN
  7. FAILED

Answer(s): C

Explanation:

This thread is considered Stuck by WebLogic because it's been running for over the time defined in MaxStuckThreadTime (600 seconds by default). Weblogic
Server waits for this time to be reached before marking a thread as stuck if the thread is still working after this time.
Example: [STUCK] ExecuteThread: '2' for queue: 'weblogic.kernel.Default (self-tuning)' id=73 idx=0x128 nid=13410 prio=1 alive, in native, daemon

A current production WebLogic Server (WLS) domain needs to be upgraded without affecting the users. What are the five steps to follow for a Rolling Update?
(Choose five.)

  1. Back up the contents of your domain.
  2. Use pack and unpack to upgrade each of the servers in the machine.
  3. Shut down the servers in a single machine.
  4. Repeat the process for all machines in the domain.
  5. Restart the servers in the machine.
  6. Repeat the process for all domains in the machine.
  7. Upgrade the servers in the machine.

Answer(s): A,C,D,E,G

Explanation:

A: Before you begin the upgrade process, make sure that you take any necessary precautions such as:
* Back up your applications, database schema, other application data, and domains.
* If required, obtain latest third party plug-ins or components that are compatible with required non-Oracle components. For example, Apache Web Server libraries.
CGED: The rolling upgrade process includes stopping the Administration Server, installing the upgrade, restarting the Administration Server, and then doing the same for each Managed Server in the cluster (machine).
