Correct Answer: CD

C: If more than one copy of myLibrary is registered, WebLogic Server selects the library with the highest specification version. If multiple copies of the library use the selected specification version, WebLogic Server selects the copy having the highest implementation version.

D: A Java EE application can reference a registered shared Java EE library using entries in the application's weblogic-application.xml deployment descriptor.

Correct Answer: D

This directory is created when the server is started for the first time.

Correct Answer: AE

A: Each connection in a data source has its own individual cache of prepared and callable statements used on the connection. However, you configure statement cache options per data source. That is, the statement cache for each connection in a data source uses the statement cache options specified for the data source, but each connection caches it's own statements.

E: When Test Connections On Reserve is enabled, when your application requests a connection from the data source, WebLogic Server tests the connection using the query specified in Test Table Name before giving the connection to the application.

Testing reserved connections can cause a delay in satisfying connection requests, but it makes sure that the connection is viable when the application gets the connection.

Correct Answer: DE

D: You were able to log in to the web application that is deployed through WebLogic. In WebLogic Server, Authentication providers are used to prove the identity

of users or system processes.

This implies that your account exists in an authentication provider.

E: Extra security is needed to use the publish link. This could be explained by a security policy attached the publish Link URL.

Correct Answer: D

The following attributes are displayed in the exhibit:

Session Invalidation Interval (in seconds)

Session Timeout (in seconds)

debug-enabled

Maximum in-memory Sessions

These attributes are stored in the weblogic.xml file as the following elements:

invalidation-interval-sec

timeout-secs

debug-enabled

max-in-memory-sessions

Incorrect answers:

A: config.xml does not contain session related information.

The config.xml file consists of a series of XML elements. The Domain element is the top-level element, and all elements in the Domain are children of the Domain

element. The Domain element includes child elements, such as the Server, Cluster, and Application elements. These child elements may have children

themselves.

For example, the Server element includes the child elements WebServer, SSL and Log. The Application element includes the child elements EJBComponent and WebAppComponent. Each element has one or more configurable attributes. An attribute has a corresponding attribute in the configuration API. For example, the Server element has a ListenPort attribute, and likewise, the weblogic.management.configuration.ServerMBean class has a ListenPort attribute.

Correct Answer: AD

A (not B): For any given WebLogic Server instance, you can override the default filter and create a log filter that causes a different set of messages to be written to

the domain log file.

Note:

To create and configure a log filter:

1.

If you have not already done so, in the Change Center of the Administration Console, click Lock and Edit (not B) (see Use the Change Center).

2.

In the left pane of the Console, select the name of the active domain in the Domain Structure panel.

3.

On the Configuration: Log Filters page, click New.

4.

On the Create a New Log Filter page, enter a value to identify the filter in the Name field.

5.

Click Finish.

The new log filter appears in the Log Filters table.

6.

To configure a filter expression, in the Log Filters table, click the log filter name.

7.

On the Configuration page, in the Filter Expression text box, enter criteria for qualifying messages.

A filter expression defines simple filtering rules to limit the volume of log messages written to a particular log destination.

See D) below.

8.

Click Save.

The filter and filter expression are listed in the Log Filters table.

D: Log Filter Configuration

Use this page to define a custom log filter to restrict the set of messages that one or more servers send to a message destination, such as the domain log,

standard out, server log file, or memory buffer of recent log events.

You can click Edit to type or paste in an expression directly, using WLDF Query Language syntax (see Related Topics, below); or you can click Add Expression to

construct an expression by choosing items from lists.

Once you create a filter, you cannot change its name. Instead, you must create a new filter under a different name.

Incorrect answers:

A: No need to shut down the server. See Note below.

B: The backup feature need to be configured. See Note below.

D: The format of the backup file is not comma-seperated.

Note: To configure the backups of the embedded LDAP server:

1.

If you have not already done so, in the Change Center of the Administration Console, click Lock and Edit

2.

Select the Domain you want to configure (for example, mydomain).

3.

Expand Security > Embedded LDAP.

4.

Set the Backup Hour, Backup Minute, and Backup Copies attributes on the Embedded LDAP Server page.

5.

Click Save to save your changes.

6.

To activate these changes, in the Change Center of the Administration Console, click Activate Changes.

Correct Answer: C

MedRec-Spring is not installed by default when you install WebLogic Server. You must choose Custom installation, then select Server Examples from the Choose Products and Component page.

Note: MedRec is an end-to-end sample Java EE application shipped with WebLogic Server that simulates an independent, centralized medical record management system. The MedRec application provides a framework for patients, doctors, and administrators to manage patient data using a variety of different clients.

MedRec demonstrates WebLogic Server and Java EE features, and highlights Oracle- recommended best practices. MedRec is included in the WebLogic Server distribution, and can be accessed from the Start menu on Windows machines. For Linux and other platforms, you can start MedRec from the WL_HOME\samples \domains\medrec directory, where WL_HOME is the top-level installation directory for WebLogic Server. A Spring version of the application is accessible from the WL_HOME\samples\domains\medrec-spring directory.
