When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:Consensus leasing – Node Manager must be running on every machine hosting managed servers within the cluster. Database leasing – Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required. Reference: https://docs.oracle.com/cd/E13222_01/wls/docs103/cluster/service_migration.html

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.Reference: https://docs.oracle.com/cd/E12839_01/web.1111/e13709/migration.htm#CLUST285

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.Reference: http://docs.oracle.com/cd/E12840_01/wls/docs103/jms/fund.html

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, daemonReference: https://blogs.oracle.com/WebLogicServer/entry/analyzing_a_stuck_weblogic_execute

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).Reference: http://docs.oracle.com/cd/E14571_01/web.1111/e13754/rolling_upgrade.htm#WLUPG268

A connection factory supports concurrent use, enabling multiple threads to access the object simultaneously. A session and its message producers and consumers can only be accessed by one thread at a time (i.e. the access must be synchronized). Their behavior is undefined if multiple threads access them simultaneously. Incorrect Answers:A, E: A connection factory supports concurrent use, enabling multiple threads to access the object simultaneously.C, D: A session and its message producers and consumers can only be accessed by one thread at a time. Their behavior is undefined if multiple threads access them simultaneously.Reference: http://docs.oracle.com/cd/E12840_01/wls/docs103/jms/fund.html

Incorrect Answers:A, B: JMS supports two messaging models: point-to-point (PTP) and publish/subscribe (pub/sub).D: As per the “Message Delivery Mode” section of the JMS Specification, messages can be specified as persistent or non-persistent.Reference: http://docs.oracle.com/cd/E12840_01/wls/docs103/jms/fund.html

A security role is a privilege granted to users or groups based on specific conditions. Like groups, security roles allow you to restrict access to WebLogic resources for several users at once. Security roles differ from groups as follows:Security roles are computed and granted to users or groups dynamically, based on conditions such as user name, group membership, or the time of day. Groups are static. Security roles can be scoped to specific WebLogic resources within a single application in a WebLogic Server domain (unlike groups, which are always scoped to an entire WebLogic Server domain). Reference: https://docs.oracle.com/cd/E13222_01/wls/docs81/secwlres/secroles.html

A: You can create Work Managers that are available only to a specific application or module. You can define application-scoped Work Managers in the WebLogic Server Administration Console and in the following descriptors:weblogic-application.xml weblogic-ejb-jar.xml weblogic.xml B: A method is assigned to a Work Manager, using the <dispatch-policy> element in the deployment descriptor.Incorrect Answers: E: Environment/Work Managers displays the Global work managers.Reference: https://docs.oracle.com/cd/E24329_01/web.1211/e24432/self_tuned.htm#CNFGD129

A Coherence cluster can contain any number of managed Coherence servers. The servers can be standalone managed servers or can be part of a WebLogic Server cluster that is associated with a Coherence cluster. storage-disabled – a managed Coherence server that is not responsible for storing data and is used to host Coherence applications (cache clients). A Coherence application GAR is packaged within an EAR and deployed on storage-disabled managed Coherence servers. storage-enabled – a managed Coherence server that is responsible for storing data in the cluster. Coherence applications are packaged as Grid ARchives (GAR) and deployed on storage-enabled managed Coherence servers. Reference: https://docs.oracle.com/middleware/1212/wls/CLUST/coherence.htm#CLUST660
