What is client and server ?

How many types of servers you

know?

Types of server

Application server, a server dedicated to running certain software applications

Communications server, carrier-grade computing platform for communications networks

Compute server, a server intended for intensive (esp. scientific) computations

Database server, provides database services to other computer programs or computers

Fax server, provides fax services for clients

File server, provides remote access to files

Game server, a server that video game clients connect to in order to play online together

Print server, provides printer services

Proxy server, acts as an intermediary for requests from clients seeking resources from other servers

Web server, a server that HTTP clients connect to in order to send commands and receive responses along with data contents

Difference b/w webserver and

Application server

The basic difference between a web server and an application server is

Webserver can execute only web applications i,e servlets and JSPs and has

only a single container known as Web container which is used to

interpret/execute web applications

Application server can execute Enterprise application, i,e (servlets, jsps, and

EJBs) it is having two containers 1. Web Container(for interpreting/executing

servlets and jsps) 2. EJB container(for executing EJBs). it can perform

operations like load balancing , transaction cluster etc

Weblogic server

WebLogic is a server software application that runs on a middle tier, between

back-end databases and related applications and browser-based thin clients.

WebLogic is a leading e-commerce online transaction processing (OLTP)

platform, developed to connect users in a distributed computing environment

and to facilitate the integration of mainframe applications with distributed

corporate data and applications.

Weblogic Admin responsibilities

Troubleshooting, Load Balancing, Clustering, Deploying Applications, Performance Tuning and Maintenance

Create, configure and tune weblogic domains/applications for performance

Code deployments/promotions, performance monitoring and performance tuning

Up gradation of WebLogic servers in development, testing and production environment and applying patch and service packs

Cluster Configuration Single Cluster, Multiple Clusters and Deployment over clusters

Server Performance Tuning - Thread Dump Analysis, Core Dump Analysis when Server crashed unevenly

JMS Configurations JMS Server, Connection Factory, Foreign JMS server, Message Bridge, Topic/Queue, Distributed destinations

Creating security roles, group policy, user authentication, auditing and authorization

Node Manager Configuration remote managed server start and stop. SSL communication between admin server and node manager

Developing WLST scripts and auto deployment process

Tuning JVM heap size to maximize the number of clients accessing the applications.

Major role of weblogic server

All oracle products are built on top of the weblogic server. Below are the few

oracle products which are being widely used in the industry.

o Oracle Webcenter

o Oracle UCM

o Oracle IDM stack

o Oracle Weblogic Portal

o Oracle Fusion Apps

o Oracle SOA

Artifacts

JAR is java archive file. It contain all class file,image,sound and other files which will needed in whole application. Computer users can create or extract JAR files using the jar command that comes with the JDK. They can also use zip tools. The Java Archive (JAR) file format enables you to bundle multiple files into a single archive file. jar was designed mainly to facilitate the packaging of java applets or applications into a single archive.

EAR -An Enterprise Archive file represents a J2EE application that can be deployed in a Web Sphere application server. EAR files are standard Java archive files and have the file extension .ear. EAR file contain ejb, web or application client module. ear file is complete j2ee application file that contain all(jar +war)

WAR -Web Archive (WAR) file is a Java archive file used to store jsp,servlets,classes,meta data information, images and Sound and tag libraries etc. Its standard file extension is .war. WAR files are used to package Web modules. A WAR file is for a Web application deployed to a servlet/jsp engine.

What is deployment descriptor ?

A deployment descriptor (DD) refers to a configuration file for an artifact

that is deployed to some container/engine.

In the Java Platform, Enterprise Edition, a deployment descriptor describes

how a component, module or application (such as a web application or

enterprise application) should be deployed. XML is used for the syntax of

these deployment descriptor files.

For web applications, the deployment descriptor must be called web.xml and

must reside in the WEB-INF directory in the web application root. For Java EE

applications, the deployment descriptor must be named application.xml and

must be placed directly in the META-INF directory at the top level of the

application .ear file.

Weblogic Installation Types

GUI Mode

Console Mode

Silent Mode

What Is GUI-Mode Installation?

GUI-mode installation is the graphics-based method of executing the weblogic

Installation program. It can be run on both Windows and UNIX systems.

To run GUI-mode installation, the console attached to the machine on which

you are installing the software must support a Java-based GUI. All consoles

for Windows systems support Java-based GUIs, but not all consoles for UNIX

systems do.

Weblogic Domain

What Is a Domain?

A domain is the basic administration unit for WebLogic Server instances. A domain

consists of one or more WebLogic Server instances (and their associated

resources) that you manage with a single Administration Server. You can define

multiple domains based on different system administrators' responsibilities,

application boundaries, or geographical locations of servers. Conversely, you can

use a single domain to centralize all WebLogic Server administration activities.

Each domain's configuration is stored in a separate configuration file called

config.xml, which is stored on the Administration Server along with other files

such as logs and security files. When you use the Administration Server to

perform a configuration task, the changes you make apply only to the domain

managed by that Administration Server

Weblogic Domain

Contents of a Domain ?

A domain can include multiple WebLogic Server clusters and non-clustered

WebLogic Server instances. A minimal domain can contain only one WebLogic

Server instance, which functions both as an Administration Server, and as a

Managed serversuch a domain can be useful while developing applications, but is not recommended for use in a production environment.

Differences Between Configuration Startup Modes

Function In development mode . . . In production mode . . .

SSL You can use the demonstration digital

certificates provided by the WebLogic Server

security services. With these certificates, you

can design your application to work within

environments secured by SSL.

A warning message is displayed if you use the

demonstration digital certificates.

Deploying Applications WebLogic Server instances can automatically

deploy and update applications that reside in

the domain_name/applications directory

(where domain_name is the name of a

domain).

The auto-deployment feature is disabled, so

you must use the WebLogic Server

Administration Console or the

weblogic.Deployer tool.

Log File Rotation When you start a server, the server

automatically renames (rotates) its local

server log file as server-name.log.n. For the

remainder of the server session, the server

rotates its local log file whenever the size of

the file reaches 500 kilobytes.

A server rotates its local log file after the size

of the file reaches 500 kilobytes.

Execute Queues The default number of threads available to

Execute Queues is 15.

The thread count determines the number of

simultaneous operations that can be

performed by applications that use the

specified execute queue.

By default, all applications use the execute

queue named default. You can create

additional queues to exercise more control

over the resources that your applications use.

The default number of threads available to

Execute Queues is 25.

JDBC Connection Pool Capacity The default capacity is 15 connections. The default capacity is 25 connections.

What is Managed Server ?

Managed Weblogic Server:

Any other server instance other than Administrative Server of a Weblogic domain

is called as Managed Weblogic Server. Managed Servers host the components and

associated resources that constitute the applicationsfor example, JSPs and EJBs.

What is Administration Server ?

Administration Server is WebLogic Server instance that maintains

configuration data for a domain. You can deploy your application on

administration Server but it is recommended to create managed Server and

deploy your application in managed server and leave Administration domain

for configuration and maintenance.

Note: There will always be atleast one Administration Server in a domain

Weblogic domain creation (Flowchart)

Weblogic domain creation

Step1: Create Domain


Step2: Select Domain Source


Step3: Configure Administrator


Step4: Select JDK & Start Mode - In below screen, you define Mode in which

you wish to start your domain and JDK (Sun, JRockit or any other JDK)

Production Mode- Domain is more secure, You need username password to

start domain or deploy application.

Development Mode- Not very secure, You can Autodeploy application and no

need to provide username/password to start Domain.


Step5:Customize your domain

On the next screen select Administration Server and Managed Servers,

Clusters and Machines.
