Correct Answer: D

Restrictions on Production Redeployment Updates

WebLogic Server can host a maximum of two different versions of an application at one time.

Note:

* When you redeploy a new version of an application, you cannot change: An application's deployment targets

An application's security model

A Web application's persistent store settings

To change any of the above features, you must first undeploy the active version of the application.

Incorrect:

*

(not A)

Production redeployment enables you to update and redeploy an application in a production environment

without stopping the application or otherwise interrupting the application's availability to clients. Production

redeployment saves you the trouble of scheduling application downtime, setting up redundant servers to

host new application versions, manually managing client access to multiple application versions, and

manually retiring older versions of an application.

*

(not C) Not dependant on whether the application is JRockit or Hotspot.

*

(not E)

The production redeployment strategy is supported for:

Standalone Web Application (WAR) modules and enterprise applications (EARs) whose clients access the application via a Web application (HTTP).

Enterprise applications that are accessed by inbound JMS messages from a global JMS destination, or from inbound JCA requests.

All types of Web Services, including conversational and reliable Web Services, but not 8.x Web Services.

Production redeployment is not supported for:

Standalone EJB or RAR modules. If you attempt to use production redeployment with such modules, WebLogic Server rejects the redeployment request. To redeploy such modules, remove their version identifiers and explicitly redeploy the modules.

Applications that use JTS drivers. For more information on JDBC application module limitations, see JDBC Application Module Limitations in Configuring and Managing JDBC Data Sources for Oracle WebLogic Server.

Applications that obtain JDBC data sources via the DriverManager API; in order to use production redeployment, an application must instead use JNDI to look up data sources.

Applications that include EJB 1.1 container-managed persistence (CMP) EJBs. To use production redeployment with applications that include CMP EJBs, use EJB 2.x CMP instead of EJB 1.1 CMP.

Correct Answer: BD

By default, JMS messages never expire. When applications send messages to queues or topics with durable subscribers, WebLogic must retain the message until it is consumed. This is fine in most point-topoint messaging applications because consumers are constantly consuming messages. Any message sent to a queue will typically be consumed in a relatively short period of time. If the consumers get disconnected, they will usually reconnect as soon as possible and start processing any messages that might have built up in the queue.

D: For durable subscribers to a topic, this is not necessarily true. The messaging system is forced to retain any message that has not been consumed by a durable subscriber, regardless of whether that durable subscriber will ever return. In this case, WebLogic is at the mercy of the durable subscriber to unsubscribe when it no longer wishes to receive the messages. If the durable subscriber logic is flawed in such a way that the subscribers do not unsubscribe properly, the messaging system will start to fill up with messages that may never be delivered. This calls for real caution in using durable subscribers. Fortunately, there is another way to help deal with this problem. Message expiration can be set at the connection factory level. Using a connection factory's default time-to-live attribute, we can specify the number of milliseconds that WebLogic should retain an undelivered message after it is sent.

Correct Answer: C

The Clone WebLogic Domain option launches a wizard that enables you to clone a WebLogic Domain from an existing reference domain that is already discovered with Cloud Control. It allows you to clone the Middleware Home and its binaries, and the domain configuration.

* If you selected the Cloning a WebLogic Domain option, the Middleware Provisioning: Domain Configuration page appears. This page contains a set of links to several pages where you can enter the properties that are most likely to be reconfigured like domain name, listen addresses for the administration server and managed servers, Node Manager/Machine configuration, and JDBC data sources.

Correct Answer: BD

B: A domain consists of one or more WebLogic Server instances (and their associated resources) that you manage with a single Administration Server.

D: In a domain, server instances other than the Administration Server are referred to as Managed Servers. Managed Servers host the components and associated resources that constitute your applications.

Incorrect:

Not A: Each WebLogic Server domain must have one server instance that acts as the Administration

Server.

Not C: A domain can include multiple WebLogic Server clusters and non-clustered WebLogic Server

instances.

Not E: 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.

A:

*

The WEB-INF directory contains the deployment descriptors for the Web application (web.xml and weblogic.xml) and two subdirectories for storing compiled Java classes and library JAR files.

*

Web Application - WEB-INF/web.xml ( WEB-INF/weblogic.xml ) The WEB-INF directory is a vital component of your web application. Web application wont run without it.It contains a heirarcy in which you'll find the necessary configuration information for your web application, and all the class files for your servlets and classes that are called up by your JSPs.

WEB-INF folder contains all the class files for your servlets and classes that are called up by your JSPs

B:

Enterprise Application - META-INF/application.xml (META-INF/weblogic-application.xml) and META-INF/

ejb-jar.xml ( META-INF/weblogic-ejb-jar.xml ) Generally comprises of EJBs. Bussiness Tier of an

application and EJB basically handels the Bussiness logic of application (distributed objects)

META-INF/application.xml containes Mappings and security roles etc.whereas META-INF/ejb- jar.xml containes ejb classes , session beans mapping etc.,

The META-INF directory is related to .jar files, It contains the manifest file which has list of jars.

A context-root setting in application.xml takes precedence over context-root setting in weblogic.xml (The context root of a web application determines which URLs weblogic will delegate to your web application.

Note:

* Deployment descriptors are xml documents that describe runtime behaviour for the deployment unit. The XML file contains information such as the context root of the web application and the mapping of the portable names of an application's resources to the application Server's resources

Correct Answer: C

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.

You can add product component functionality or additional applications and services to an existing WebLogic domain by extending it using the Configuration Wizard. For example, if you created a base WebLogic domain and you want to add the Avitek Medical Records Examples functionality, you can extend the domain by using the medrec.jar template.

The Configuration Wizard simplifies the task of extending an existing WebLogic domain by using extension templates. Oracle provides various sample extension templates, as well as extension templates for various Fusion Middleware products. You can also create your own extension templates using WLST or the unpack command.

Correct Answer: AC

When an application that references a shared library or package is deployed, WebLogic Server checks the

names and version string requirements against the libraries registered with the server. If an exact match

for a library or package name is not found, or if the version requirements are not met, the application

deployment fails.

If WebLogic Server finds a name and version string match for all of the libraries referenced in the

application, the server adds the libraries' classes to the classpath of the referencing application and

merges deployment descriptors from both the application and libraries in memory. The resulting deployed

application appears as if the referenced libraries were bundled with the application itself.

Note:

As a best practice, your development team should always include version string information for a library or

optional package in the manifest file for the deployment. See Editing Manifest Entries for Shared Libraries

in Developing Applications for Oracle WebLogic Server for more information.

If you are deploying a library or package that does not include version string information, you can specify it

at the command line using one or both of the following options:

libspecver--Defines a specification version for the library or package.

libimplver--Specifies an implementation version for the library or package.
