1Z0-102 Online Practice Questions and Answers

Correct Answer: D

A Managed Server is a WebLogic Server instance that runs deployed applications. It refers to the Administration Server for all of its configuration and deployment

information. Usually, you use Managed Servers to run applications in a production environment.

See step 4 and 5 below in particular:

To use the WebLogic Server scripts to start Managed Servers:

1.

Refer to Starting Servers: Before You Begin for prerequisite tasks.

2.

If you have not already done so, create one or more Managed Servers.

See Creating WebLogic Domains Using the Configuration Wizard or "Create Managed Servers" in the Administration Console Online Help.

3.

Start the domain's Administration Server.

4.

In a shell (command prompt) on the computer that hosts the Managed Server, change to the directory that contains the startManagedWebLogicscript:

DOMAIN_NAME\bin\startManagedWebLogic.cmd (Windows)

DOMAIN_NAME/bin/startManagedWebLogic.sh (UNIX)

where DOMAIN_NAME is the directory in which you located the domain. By default, this directory is BEA_HOME\user_projects\domains\DOMAIN_NAME.

5.

Enter one of the following commands:

startManagedWebLogic.cmd managed_server_name

admin_url (Windows)

startManagedWebLogic.sh managed_server_name

admin_url (UNIX)

where managed_server_name specifies the name of the Managed Server and admin_url specifies the listen address (host name or IP address) and port number

of the domain's Administration Server.

For example, the following command uses startManagedWebLogic.cmd to start a Managed Server named myManagedServer. The listen address for the domain's

Administration Server is AdminHost:7001:

c:\bea\user_projects\domains\mydomain\bin\startManagedWe bLogic.cmd myManagedServer http://AdminHost:7001

6. For each Managed Server that you want to start, open a separate command shell and follow steps 4 and 5. If you are starting Managed Servers on another machine, log in to that machine (remotely or locally) and then follow steps 4 and 5.

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.

Correct Answer: B

JMS Configuration option ' Messages Threshold High':

The upper threshold (number of messages stored in this JMS server) that triggers flow control and logging events. A value of -1 disables the events for this JMS

server. If the number of messages exceeds this threshold, the triggered events are:

Log Messages

-A message is logged on the server indicating a high threshold condition. Flow Control

-If flow control is enabled, the JMS server becomes armed and instructs producers to begin decreasing their message flow.

Correct Answer: D

When you create a JDBC resource (data source or multi data source) using the Administration Console or using the WebLogic Scripting Tool (WLST), WebLogic Server creates a JDBC module in the config/jdbc subdirectory of the domain directory, and adds a reference to the module in the domain's config.xml file.

Reference: Configuring WebLogic JDBC Resources

Correct Answer: ABE

A: The Configure the Administration Server window prompts you to define the configuration information for the Administration Server, including: Administration Server name Listen address Nonsecure and secure (optional) listen ports

B: The Configure Managed Servers window prompts you to define the configuration information for one or more Managed Servers, including: Managed Server name Listen address Nonsecure and secure (optional) listen ports

E: The Configure Clusters window prompts you to define the configuration information for one or more clusters, including: Cluster name Multicast address and port Cluster address that identifies the Managed Servers in the cluster Frontend host if you are using a proxy server or a firewall. Frontend HTTP port if you are using a proxy server or a firewall.

Correct Answer: ABCE

A: When creating a JDBC data source using the Administration Console, you are prompted to select a JDBC driver. The Administration Console provides the driver class name and helps you construct the URL as required by the driver.

B: JDBC Data Source: Targets. Use this page to select the servers or clusters on which you would like to deploy this JDBC data source.

C: JNDI Name, The JNDI path to where this data source is bound. By default, the JNDI name is the name of the data source.

E: When deciding which JDBC driver to use to connect to a database, you should try drivers from various vendors in your environment. In general, JDBC driver performance is dependent on many factors, especially the SQL code used in applications and the JDBC driver implementation.

Correct Answer: BE

B: The Administration Server uses the machine definition in conjunction with the Node Manager application to start remote WebLogic Server instances.

E: By default, WebLogic Server attempts to create session state replicas on a different machine than the one that hosts the primary session state. You can further control where secondary states are placed using replication groups. A replication group is a preferred list of clustered servers to be used for storing session state replicas. Using the WebLogic Server Console, you can define unique machine names that will host individual server instances. These machine names can be associated with new WebLogic Server instances to identify where the servers reside in your system. Machine names are generally used to indicate servers that run on the same machine.

Correct Answer: B

For durable subscriptions, WebLogic JMS stores a message in a persistent file or database until the message has been delivered to the subscribers or has expired, even if those subscribers are not active at the time that the message is delivered.

Note #1: Durable subscriptions means that weblogic server will store the messages in a persistent store (i.e a file-store or a JDBC-store) until those messages are delivered to the subscribers/listener. This technic helps weblogic server to make sure that the messages get delivered even if those subscribers/listeners are not active at the time that the message is getting delivered.

As all of us know that in Topic's the senders/producers just send the messages to the topic and the receivers/listeners have subscribe them self to get those messages, hence senders/producers does not have any concern if the messages are been received or not. However with this feature weblogic make sure all the subscribers would get the messages as the messages gets stored in a persistence store.

Note #2:

*

Consumers Current Count: Current number of consumers accessing this destination

*

MessagesCurrentCount: The current number of messages in the destination. This does not include the pending messages.

*

MessagesPendingCount: The number of pending messages in the destination.

Pending messages are over and above the current number of messages. A pending message is one that has either been sent in a transaction and not committed, or that has been received and not committed or acknowledged.

Incorrect answers:

A: When a topic is paused for production, it prevents any new message production operations from both new and existing producers attached to that topic.

C: There is no pending message here. So there cannot be a message that a consumer has not acknowledged.

D: Non-durable messages are not stored.

Correct Answer: ABE

A, E: Node Manager enables you to perform these tasks:

*

Start and stop remote Managed Servers. (E)

*

Monitor the self-reported health of Managed Servers and automatically kill server instances whose health state is "failed".

*

Automatically restart Managed Servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot. (A)

B: The WebLogic Server installation process installs Node Manager to run as an operating system service: a daemon on UNIX machines, or a Windows service on Windows-based machines. An operating system service starts up automatically each time the operating system boots. A key Node Manager feature is the ability to restart Managed Servers after a failure. If the failure is a machine crash, running Node Manager as a service ensures

that Node Manager starts up automatically when the machine reboots, and is available to restart Managed Servers on that machine.

E: Requests from the Administration Console (or JMX utilities such as weblogic.Admin) to start a Managed Server using Node Manager are issued to the Administration Server for the domain that contains the Managed Server.

Correct Answer: ACEF

A: Steps to Deploy Application using Administration Console

1.

Start the Admin Server and Managed Server.

2.

Navigate to Administration console http://localhost:7001/console and login.

3.

Navigate to Domain Environment > Deployments. Lock the console.

4.

Etc.

E: To enable the administration port for your domain:

1.

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

2.

Shutdown all Managed Servers in the domain. You cannot enable the administration port dynamically on a Managed Server.

3.

Ensure that all servers in the domain are properly configured to use SSL.

4.

In the left pane of the Console, under Domain Structure, select the domain name.

5.

Select Configuration > General and select the Enable Administration Port check box to enable the SSL administration port for this domain.

6.

In the Administration Port field, enter the SSL port number that server instances in the domain use as the administration port. You can override an individual server instance's administration port assignment on the Advanced options portion of the Configuration: General page for the server instance.

7.

Click Save.

8.

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

Note: If you want to use the Administration Console to make configuration changes, you must first click the Lock and Edit button in the Change Center. When you click Lock and Edit, you obtain a lock on the editable hierarchy of Configuration MBeans for all servers in the domain (the edit tree). As you make configuration changes using the Administration Console, you click Save (or in some cases Finish) on the appropriate pages. This does not cause the changes to take effect immediately; instead, when you click Save, you are saving the change to the edit tree and to the DOMAIN_NAME/pending/config.xml file and related configuration files. The changes take effect when you click Activate Changes in the Change Center. At that point, the configuration changes are distributed to each of the servers in the domain. If the changes are acceptable to each of the servers, then they take effect. (Note, however, that some changes require a server to be restarted.) If any server cannot accept a change, then all of the changes are rolled back from all of the servers in the domain. The changes are left in a pending state; you can then either edit the pending changes to resolve the problem or revert the pending changes.
