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

Web Server is designed to serve HTTP Content. App Server can also serve HTTP Content but is not limited to just HTTP. It can be provided other protocol support such as RMI/RPC

Web Server is mostly designed to serve static content, though most Web Servers have plugins to support scripting languages like Perl, PHP, ASP, JSP etc. through which these servers can generate dynamic HTTP content.

Most of the application servers have Web Server as integral part of them, that means App Server can do whatever Web Server is capable of. Additionally App Server have components and features to support Application level services such as Connection Pooling, Object Pooling, Transaction Support, Messaging services etc.

As web servers are well suited for static content and app servers for dynamic content, most of the production environments have web server acting as reverse proxy to app server. That means while servicing a page request, static contents (such as images/Static HTML) are served by web server that interprets the request. Using some kind of filtering technique (mostly extension of requested resource) web server identifies dynamic content request and transparently forwards to app server

Example of such configuration is Apache Tomcat HTTP Server and Oracle (formerly BEA) WebLogic Server. Apache Tomcat HTTP Server is Web Server and Oracle WebLogic is Application Server.

Application servers widely used in IT

Redhat Jboss

IBM Websphere

Oracle Weblogic

Oracle Webcenter

Oracle Glassfish

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

Weblogic server

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 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 server—such 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 applications—for 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

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
