How could I achieve this? Post a Comment. Wednesday, January 8, Websphere Basic Concepts. Application support. Java EE applications. Portlet applications. Portlets are packaged in WAR files. Session Initiation Protocol applications. SIP is used to establish, modify, websphere application server 6.1 basics, and terminate multimedia IP sessions. SIP negotiates the medium, the transport, websphere application server 6.1 basics, and the encoding for the call.

After the SIP call has been established, the communication takes place over the specified transport mechanism, independent of SIP. Examples of application types that use SIP include voice over IP, click-to-call, and websphere application server 6.1 basics messaging. Business level applications. This is a new administration concept that expands the options previously offered by Java EE. This grouping notion for enterprise-level applications includes WebSphere and non-WebSphere artifacts like Service Component Architecture SCA packages, libraries, and proxy filters under a single application definition.

Every artifact in the group is a composition unit. A business level application can be useful when an application has the following characteristics:. WebSphere and non-WebSphere runtimes. At the heart of each member of the WebSphere Application Server family is an application server. Each family has essentially the same architectural structure.

Although the application server structure for the Base and Express platforms is identical, there are differences in licensing terms and platform support.

With the Base and Express platforms, you are limited to stand-alone application servers. The Network Deployment platform enables more advanced topologies that provide workload management, scalability, high availability, and central management of multiple application servers. You can also manage multiple Base profiles centrally, but you will not have workload management, scalability, and high availability capabilities, websphere application server 6.1 basics.

Runtime environments are built by creating profiles. A profile can define a deployment manager, a stand-alone application server, or an empty node to be federated added to a cell. Each profile contains files specific to that runtime such as logs and configuration files. Profiles can be created during and after installation. After the profiles have been created, further configuration and administration is performed using the WebSphere administrative tools. Stand-alone application servers. All WebSphere Application Server packages support a single stand-alone server environment.

An application server runs websphere application server 6.1 basics or more applications and provides the services required to run those applications. Each stand-alone server is created by defining an application server profile.

They run isolated from each other. Distributed application servers. A distributed server configuration can be created in one of three ways:. Application servers concepts. Regardless of the configuration, WebSphere Websphere application server 6.1 basics Server is organized based on the concept of cells, nodes, and servers.

Although all of these elements are present in each configuration, cells and nodes do not play an important role until you take advantage of the features provided with Network Deployment. These cells, nodes, websphere application server 6.1 basics, and servers can be managed by a combination of deployment managers, administrative agents, and job managers.

Application servers. The application server is the primary runtime component in all configurations and is where an application actually executes. All WebSphere Application Server configurations can have one or more application servers. In the Express and Base configurations, each application server functions as a separate entity.

There is no workload distribution or central administration among application servers. With Network Deployment, you can build a distributed server environment consisting of multiple application servers maintained from a central administration point. In a distributed server environment, you can cluster application servers for workload distribution and failover. A node is an administrative grouping of application servers for configuration and operational management within one operating system instance virtualization allows multiple operating systems on one machine.

It is possible to create multiple nodes inside one operating system instance, websphere application server 6.1 basics, but a node cannot leave the operating system boundaries. In a stand-alone application server configuration, there is only one node. With Network Deployment, you can configure a distributed server environment consisting of multiple nodes that are managed from one central administration server.

Node agents. In distributed server configurations, each node has a node agent that works with the deployment manager to manage administration processes. A node agent is created automatically when you add federate a stand-alone node to a cell. It is not included in Base and Express configurations, websphere application server 6.1 basics.

Node groups. A node group is a grouping of nodes within a cell that have similar capabilities. A node group validates that the node is capable of performing certain functions before allowing them. A DefaultNodeGroup is automatically created, websphere application server 6.1 basics. This node group contains the deployment manager and any new nodes with the same platform type. A node can be a member of more than one node group. Nodes in the same sysplex must be in the same sysplex node group.

A node can websphere application server 6.1 basics in one sysplex node group only. A cell is a grouping of nodes into a single administrative domain. That node contains one server. This is referred to as a heterogeneous cell. Deployment managers. Administrative agents. With V7.

Job managers. Application servers provide the runtime environment for application code. WebSphere Application Server V7. Application server clusters. Application servers that are a part of a cluster are called cluster members. Proxy servers. WebSphere Application Server allows you to create two types of proxy servers:. Web servers. Web servers are associated with nodes. These nodes can be managed or. Web server plug-ins. Generic servers. The WebSphere Application Server generic.

There are two basic types of generic application servers:. Containers provide runtime support for applications. Application server containers. Each application server provides the following container support:. Intelligent runtime provisioning. Application client container.

Workload management. Routing of servlet requests occurs between the Web server plug-in and the. This routing is based on weights associated with the cluster members. A guideline formula for determining routing preference is as follows:. Where there are n cluster members in the cluster. Transaction and process affinity are considered in this policy. High availability. They offer the following features:. There websphere application server 6.1 basics multiple levels of administration in WebSphere Application Server:.

Web services. As a provider, WebSphere Application.
