  ---

  The Administration Console user interface includes the following panels.

  *

  Breadcrumb Navigation

  A series of links that show the path you have taken through the Administration Console's pages.

  *

  Change Center

  This is the starting point for using the Administration Console to make changes in WebLogic Server.

  *

  Domain Structure

  This panel is a tree you can use to navigate to pages in the Administration Console.

  *

  How do I...

  This panel includes links to online help tasks that are relevant to the current Console page.

  *

  Tool Bar

  The tool bar at the top of the Console.

  *

  System Status

  The System Status panel reports on the number of information, error, and warning messages that have been logged.

  H: To help automate the task of configuring a domain, you can record your configuration actions in the Administration Console as a series of WebLogic Scripting Tool (WLST) commands and then use WLST to replay the commands.

  For details see: Administration Console Online Help, Record WLST Scripts

  Incorrect answers:

  A: To edit XML files, use the BEA XML Editor, an entirely Java-based XML stand-alone editor.

  B: On Windows, a shortcut on the Start menu sets the environment variables and invokes WLST (Tools-->WebLogic Scripting Tool).

  E: he Template Builder is a standalone Java application that prompts you to create custom configuration and extension templates that can be used later for creating and updating domains via the Configuration Wizard. Using an existing

  domain or template, the Template Builder guides you through the process of creating custom configuration and extension templates. You can then package these templates or extension templates with your software so your customers can

  use them to customize their WebLogic Platform environments. The Template Builder is especially useful for ensuring that the required environment for WebLogic- based products can be installed and configured easily by your customers at

  their sites.

  G: * To start and run the Configuration Wizard on a Windows computer, select the Configuration Wizard option from the BEA program group in the Windows Start Menu.

  * To start and run the Configuration Wizard in a GUI environment on a UNIX computer (or from a Windows command prompt):

  Log in to a Windows or UNIX system on which the WebLogic Server software is installed.

  Open a command-line shell.

  Go to the following directory: WL_HOME/common/bin

  where WL_HOME is the directory in which you installed WebLogic Server. For example:

  cd ~/bea/weblogic810/common/bin

  Invoke the config.cmd or config.sh script.

  If you try to start the Configuration Wizard on a system that cannot support the graphical display, the wizard automatically starts in console mode.

• Question 13:

  Which two statements are true about Log Filters?

  A. Log Filters are created at the domain level.
  B. You do not have to lock the configuration to create Log Filters.
  C. You can apply a Log Filter to the server log, but not to standard out.
  D. The administration console assists in the creation of Log Filter expressions
  A. Log Filters are created at the domain level.
  D. The administration console assists in the creation of Log Filter expressions

  ---

  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.

• Question 14:

  Your domain includes a cluster of five servers, but only three are currently running. A colleague then uses the administration console to install and deploy a new EJB application to the cluster. By default, which outcome would you expect?

  A. The application deploys successfully on the three servers that are running.
  B. The deployment fails because the entire cluster is not running.
  C. The deployment succeeds, but the application is not accessible.
  D. The user is prompted to start the two unavailable servers before continuing.
  E. The two unavailable servers are automatically removed from the cluster.
  A. The application deploys successfully on the three servers that are running.

  ---

  Note #1: If your EJBs will run on a WebLogic Server cluster, Oracle recommends that you deploy them homogeneously--to each Managed Server in the cluster. Alternatively, you can deploy an EJB to only to a single server in the cluster (that

  is, "pin" a module to a server). This type of deployment is less common, and should be used only in special circumstances where pinned services are required.

  Note #2: When you deploy an EJB, you specify the servers and clusters to which the EJB deployment is targeted. After you have deployed an EJB, you can update the servers and clusters to which it is targeted.

  To set target servers and clusters for a deployed EJB:

  1.

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

  2.

  In the left pane of the Administration Console, select Deployments.

  The right pane lists the EJBs and other modules that you have deployed, or tried to deploy.

  3.

  In the right pane, click the desired EJB.

  4.

  Select the Targets tab.

  Servers and clusters in the domain are displayed.

  5.

  Select the check box next to the individual servers and/or clusters to which you wish to deploy the EJB and click Save.

  By default, the Administration Console deploys an EJB to all server instances in the cluster (the "All servers in the cluster" option). To deploy the EJB to selected servers in a cluster, select "Part of the cluster", and then select the individual server instances to which you want to deploy the EJB.

  6.

  To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately--some require a restart

• Question 15:

  Identify two true statements about an Oracle WebLogic Server JMS Connection Factory.

  A. A default JMS Connection Factory exists and is named weblogic.jms.connections
  B. A Connection Factory can be targeted to only one WebLogic Server.
  C. A JMS Connection Factory's Default Priority and Default Time-to-Live attribute cannot be modified after the Connection Factory is created.
  D. A JMS Connection factory can be created as a system module resource within the administration console.
  B. A Connection Factory can be targeted to only one WebLogic Server.
  D. A JMS Connection factory can be created as a system module resource within the administration console.

  ---

  Incorrect answers:

  A: WebLogic JMS defines two default connection factories, which you can look up using the following JNDI names:

  weblogic.jms.ConnectionFactory

  weblogic.jms.XAConnectionFactory

  C: Both Default Priority and Default Time-to-live can be changed:

  Default Priority: This attribute is dynamic. It can be changed at any time. However, changing the value does not affect existing connections. It only affects new connections made with this connection factory.

  Default Time-to-Live:

  This attribute is dynamic. It can be changed at any time. However, changing the value does not affect existing connections. It only affects new connections made with this connection factory.

• Question 16:

  You wish to provide failover for HTTP sessions within a cluster. However, you are limited by the following constraints:

  1.

  While under load, your servers have very little free memory.

  2.

  you do not have appropriate access rights to modify your company's database.

  Which is the best option, given these restrictions?

  A. in-memory replication
  B. automatic migration
  C. file persistence
  D. JDBC persistence
  E. replication groups
  C. file persistence

  ---

  File persistence use less memory than in-memory replication, and does not need access rights to the company's database.

  Note:

  You use session persistence to permanently store data from an HTTP session object to enable failover and load balancing across a cluster of WebLogic Servers. When your applications stores data in an HTTP session object, the data must

  be serializable. There are five different implementations of session persistence:

  *

  Memory (single-server, non-replicated)

  *

  File system persistence

  *

  JDBC persistence

  *

  Cookie-based session persistence

  *

  In-memory replication (across a cluster)

  Incorrect answers:

  A: Using in-memory replication, WebLogic Server copies a session state from one server instance to another. The primary server creates a primary session state on the server to which the client first connects, and a secondary replica on another WebLogic Server instance in the cluster. The replica is kept up-to-date so that it may be used if the server that hosts the servlet fails.

  D: JDBC persistence stores session data in a database table using a schema provided for this purpose. You can use any database for which you have a JDBC driver. You configure database access by using connection pools.

  Note: When you use memory-based storage, all session information is stored in memory and is lost when you stop and restart WebLogic Server.

  B. The command does a "Force" shutdown.
  C. The command blocks user interaction.
  D. The command has timeout of 30,000 milliseconds.
  A. The server you are connected to will shut down.

  ---

  The WLST life cycle shutdown command gracefully shuts down a running server instance or cluster.

• Question 18:

  A domain created based on the Basic WebLogic Server Domain product has start scripts called startWebLogic.sh and startManagedWebLogic.sh (.cmd in Windows). Which three statements are true?

  A. startWebLogic.sh starts Node Manager.
  B. startWebLogic.sh has a required parameter.
  C. startManagedWebLogic.sh has a required parameter.
  D. startWebLogic.sh starts the Administration Server of the domain.
  E. startManagedWebLogic.sh can start any managed server in the domain.
  F. Both scripts can start any WebLogic Server, but each has different default parameter values.
  C. startManagedWebLogic.sh has a required parameter.
  D. startWebLogic.sh starts the Administration Server of the domain.
  E. startManagedWebLogic.sh can start any managed server in the domain.

  ---

  C: If you created Managed Server while creating domain then you can start Managed Server using startManagedWebLogic command

  $BEA_HOME/user_projects/domains//bin

  startManagedWebLogic.cmd (for Windows) startManagedWebLogic.sh (for Unix)

  Assume that we a created Managed Server MS1 with Admin Port as 7003.

  startManagedWebLogic.cmd ms1 http://localhost:7003 (Windows)

  D: Starting Administration Server (startWebLogic.cmd or .sh)

  E: Starting Managed Server (startManagedWebLogic.sh or .cmd)

• Question 19:

  You are installing Oracle WebLogic Server 11g for some new developers in the department. They have asked for a very generic installation for development and want you to ensure that the "MedRec" sample domain is included. What should you do to accomplish this?

  A. Select the typical installation because the "MedRec" sample domain is included in it.
  B. You won't be able to do this, because all the samples were removed from the installer after 10g.
  C. Select the custom installation and select Server Examples.
  D. After installation, create a sample domain named "MedRec" by using the Configuration Wizard.
  C. Select the custom installation and select Server Examples.

  ---

  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.

  Tasks WebLogic Server Product Installation Procedure Step 1 - Obtain the appropriate installation file for your platform Step 2 - Complete the installation planning requirements Ensure that your system environment meets the requirements for the installation. Also determine your Oracle Middleware home directory, and product installation home directories. (C) When you are installing WebLogic Server, you are prompted to choose an existing Middleware home directory or specify a path to create a new Middleware home directory. If you choose to create a new directory, the installation program automatically creates it for you. Step 3 - Determine the appropriate installation mode for your situation Step 4 - Determine the type of installation (A) There are two types of installation Typical or Custom. The type of installation depends on the products and sub-components you want to install. Step 5 - Install the software Step 6 - Create a WebLogic domain

  E: The JDK selection screen.

  This screen is displayed only if you selected a Custom installation. It is not displayed if you are running an Upgrade installer. This screen displays a list of JDKs. This list contains JDKs that are available for (and common across) previous

  installations of all the selected WebLogic Server components.

  Select the JDK that you want to install with the product.

  Incorrect answers:

  B: There are different platforms on which Weblogic can be installed. Such as Windows, Linux, and UNIX.

  D: To receive updates you must register. However, you do not do that during the graphic installation phase. Note: You must have an active My Oracle Support account in order to download an Upgrade installer. You can also install patch releases using the Smart Update tool, which is included with WebLogic Server. Smart Update requires that you have an active My Oracle Support account.

  If a patch release or patch set is available for your current WebLogic Server installation, you can download an Upgrade installer from My Oracle Support. Upgrade installers let you install an available patch release or patch set onto an existing WebLogic Server installation.
