Domain: Overview

• A domain is the basic administration unit for Oracle WebLogic

Server.

• It always includes one Oracle WebLogic Server instance

configured as an administration server.

• It may include optional Oracle WebLogic Server instances in a

domain, called managed servers.

• It may also include clusters of server instances that work

together.

Domain Restrictions

• Each domain requires its own administration server.

• A cluster cannot span multiple domains.

• The managed servers in a domain must all run the same

version of Oracle WebLogic Server.

• The administration server in a domain must run the same

or a higher version of the WebLogic Server software as the managed servers in the domain.

• Domains cannot share a configured resource or subsystem

between domains.

• Two or more system resources cannot have the same

name within a domain.

Trang 7

• A “server” is an instance of weblogic.Server executing

in a Java Virtual Machine (JVM).

• A server:

– Runs on a designated Oracle WebLogic Server machine

– Has a dedicated amount of RAM

– Is multithreaded

• A machine can be associated with multiple servers.

• The two types of servers are:

– Administration server

– Managed server

Trang 8

Administration Server

• Is the central point of control for a domain

• Stores the configuration information and logs for a domain

• Runs the WebLogic administration console

Trang 9

Managed Server

• It is any server in a domain that is not the administration server.

• It contacts the administration server for configuration

information.

• It runs business applications in a production environment.

• It is independent of all other managed servers in the domain

(unless they are in a cluster).

• There may be many managed servers in a domain.

• Individual managed servers are typically added for capacity and

Trang 10

Interaction Between the Administration Server

and Managed Servers

• The administration server stores the master copy of the

domain configuration, including the configuration for all managed servers in the domain.

• Each managed server stores a local copy of the domain

configuration file.

• When a managed server starts, it connects to the

administration server to synchronize the configuration.

• When the configuration is changed, the administration

server sends the changed configuration to the managed servers.

Trang 11

What Is a Machine?

• The main purpose of a machine is to administratively

manage servers.

• Machines are required by the node manager.

• Machines are optionally used by clusters.

• A machine is a logical description, not a physical entity.

Trang 12

Relationship of Machines to Other Components

There are many ways to set up the topology.

Trang 13

• A cluster is a logical group of WLS servers.

• Oracle WebLogic Server (WLS) clusters provide:

– High availability (reliability)

– Load balancing (scalability)

• A cluster is transparent to a client.

Trang 14

Cluster Guidelines

• A cluster cannot span domains.

• All servers in a cluster must also be in the same domain.

• All servers in a cluster must be at the same version level.

• Clustered servers can be on the same or on different

machines with the same or different operating systems.

• There can be multiple clusters in a domain.

Trang 15

WebLogic Scripting Tool (WLST)

• The WLS command-line tools are useful:

– For automating common administration activities – As an alternative to the administration console

– When graphical tools are not supported

• WLST provides a command-line interface for:

– Creating new WLS domains

– Retrieving and updating WLS domain configurations – Deploying applications

– Obtaining run-time server statistics

Trang 16

WLST Modes

• Online mode:

– Available when connected to a running server

– Provides access to all WLS configuration and run-time

attributes – Can be used to create and activate change sessions, similar

to using the WLS console

• Offline mode:

– Available when domain is not running

– Provides access to only persisted domain configuration

(config.xml) – Can be used to create or update domains, similar to using the Configuration Wizard

Trang 17

WLST Example

[oracle@edvmr1p0 /]$ java weblogic.WLST

Initializing WebLogic Scripting Tool (WLST)

Welcome to WebLogic Server Administration Scripting Shell

Type help() for help on available commands

wls:/offline> connect('weblogic','password','t3://localhost:7001')

Connecting to t3://localhost:7001 with userid system

Successfully connected to Admin Server 'myAdmin' that belongs to domain 'mydomain'

Warning: An insecure protocol was used to connect to the server To

ensure on-the-wire security, the SSL port or Admin port should be used instead

Oracle Fusion Middleware Home and Oracle

WebLogic Server Home

• Oracle Fusion Middleware home:

– Consists of the Oracle WebLogic Server home and,

optionally, one or more other Oracle product homes (also known as Oracle homes; such as Identity Management home)

– Resides on a local file system or on a remote shared disk that is accessible through NFS

– Is represented as MW_HOME

• Oracle WebLogic Server home:

– Contains installed files necessary to host Oracle WebLogic Server

– Is a peer of other Oracle home directories underneath the Middleware home directory

– Is represented as WL_HOME

Trang 21

Oracle Home

• Oracle home:

– Is the top-level installation directory for Oracle products

– Resides on a local file system or on a remote shared disk that is

accessible through NFS

– Is where product binaries and read-only files reside

– Contains files that are not updated during the normal running of the application server components

— Files are updated only when you apply a patch or upgrade.

– Is represented as ORACLE_HOME

• Oracle instance:

– Contains all configuration files, repositories, log files, deployed

applications, and temporary files (updatable files)
