Correct Answer: B

To manage work in your applications, you define one or more of the following Work Manager components:

Fair Share Request Class:

Response Time Request Class:

Min Threads Constraint:

Max Threads Constraint:

Capacity Constraint

Context Request Class:

Note:

*

max-threads-constraint--This constraint limits the number of concurrent threads executing requests from the constrained work set. The default is unlimited. For example, consider a constraint defined with maximum threads of 10 and shared by 3 entry points. The scheduling logic ensures that not more than 10 threads are executing requests from the three entry points combined. A max-threads-constraint can be defined in terms of a the availability of resource that requests depend upon, such as a connection pool. A max-threads-constraint might, but does not necessarily, prevent a request class from taking its fair share of threads or meeting its response time goal. Once the constraint is reached the server does not schedule requests of this type until the number of concurrent executions falls below the limit. The server then schedules work based on the fair share or response time goal.

*

WebLogic Server prioritizes work and allocates threads based on an execution model that takes into account administrator-defined parameters and actual run-time performance and throughput.

*

WebLogic Server uses a single thread pool, in which all types of work are executed. WebLogic Server

Administrators can configure a set of scheduling guidelines and associate them with one or more applications, or with particular application components.

prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.

The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues.

Correct Answer: A

A: a WebLogic domain can be created by using the Configuration Wizard in graphical mode.

B: WLST enables you to create a new domain or update an existing domain

D: A domain template is a JAR file that contains domain configuration documents, applications, security data, startup scripts, and other information needed to create a domain.

Correct Answer: B

Note:

*

A Node Manager process is not associated with a specific WebLogic domain but with a machine. You can use the same Node Manager process to control server instances in any WebLogic Server domain, as long as the server instances reside on the same machine as the Node Manager process. Node Manager must run on each computer that hosts WebLogic Server instances--whether Administration Server or Managed Server--that you want to control with Node Manager.

*

In managing multiple servers, Node Manager uses multiple configuration files and outputs log files to multiple directories.

*

nodemanager.domains This file contains mappings between the names of domains managed by Node Manager and their corresponding directories.

Correct Answer: ABC

A: Oracle Smart Update is a standalone Java application that is automatically installed in the Middleware home utils/bsu directory. Smart Update simplifies the process of applying patches to your WebLogic Server installation. When support makes a patch available for an installed version of WebLogic Server, you download the patch from My Oracle Support and then use Oracle Smart Update to apply it to your installation. Smart Update organizes all available updates for you, and has several features that allow a great deal of customizing in the way various patches are applied and managed in your environment.

B: As part of a new Enterprise Manager system, the installation wizard does the following:

* Oracle My Oracle Support Management Plug-In etc.

C: Applying patch from server start script:

After downloading the patch (jar file) follow the below steps:

-Stop your server.

-Then take the path of the folder which has the CRxxxxxx_xxxmpx.jar file and copy it in the CLASSPATH of setDomainEnv.cmd which is in

(/user_projects/domains//bin/setDomainEnv.cmd)

For example, the script would look something like this: set CLASSPATH=%PRE_CLASSPATH%;%WEBLOGIC_CLASSPATH%; C:\extra\my_projects\doc\CR\CR218639_920mp3.jar;C:\extra\my_projects\doc \CR\ CR360676_920mp3.jar;C:\extra\my_projects\doc\CR\CR367966_920mp3.jar; C:\extra\my_projects\doc\CR\CR368155_920mp3.jar;C:\extra\my_projects\doc\CR\CR370311_ 920mp3.jar

-Re-start your server.

-You should see the patch applied in the stdout file.

The WebLogic Server Management Pack EE greatly improves application performance by providing unique functionality to automatically detect performance bottlenecks; quickly diagnose these performance problems, and identify their root cause. Key application performance management features of the pack include the following:

*

(A) Manage multiple farms and WebLogic Domains centrally

*

Monitor Oracle Coherence Cluster including all nodes within a cluster, all caches, services, connection

managers and connections

*

Monitor middleware availability and performance out-of-box; track such data historically, and receive notifications of potential problems

*

Obtain real-time, in-depth JVM diagnostics without instrumentation overhead

*

Trace transactions across containers as well as to the database

*

(E) Analyze call paths and dependencies via graphical, architecture views

*

(E) Automatically discover and model dependencies between Java components, frameworks, and web services

Correct Answer: A

Correct Answer: B

WebLogic Server includes features that allow deployed applications to easily use Coherence data caches, and seamlessly incorporate Coherence*Web (not A) for session management and TopLink Grid (not C) as an object-to-relational persistence framework. Collectively, these features are referred to as ActiveCache.

ActiveCache is employed by applications running on WebLogic Server and provides replicated and distributed caching services that make an application's data available to all servers in a Coherence data cluster. New features in this release provide direct access by applications to data caches, either through resource injection or component-based JNDI lookup, and let you display, monitor, create, and configure Coherence clusters using the WebLogic Server Administration Console and WLST.

Correct Answer: BCD

B, D: In addition to the coherence.jar file, Coherence provides a deployable shared library, coherence-web-spi.war, that contains a native plug-in to WebLogic Server's HTTP Session Management interface. Coherence also provides the active-cache-1.0.jar file which contains the classes that allow WebLogic Server to interact with Coherence.

C: The active-cache-1.0.jar is included in the WebLogic Server installation.
