Learn about the WebSphere® Application Server full profile.
An application server is a Java™ virtual machine (JVM) running user applications. Application servers use Java technology to extend web server capabilities to handle web application requests. An application server makes it possible for a server to generate a dynamic, customized response to a client request. The WebSphere Application Server full profile provides application servers.
For more introduction, refer to Introduction: Application servers.
Generic servers. In distributed platforms, you can use the full profile generic servers feature to create a generic server as an application server instance within the product administration, and associate it with a non-WebSphere server or process. The generic server can be associated with any server or process that is necessary to support the application server environment.
For more information, refer to Server collection.
Web servers. A full profile server works with a web server to handle requests for web applications. The application server and web server communicate using an HTTP plug-in for the web server.
For more information, refer to Implementing a web server plug-in.
JMS providers. The product supports messaging by providing a range of Java Message Service (JMS) providers that conform to the JMS specifications. There are three main types of JMS provider that can be configured for the full profile: The WebSphere Application Server default messaging provider (uses service integration as the provider), the WebSphere MQ messaging provider (uses your WebSphere MQ system as the provider) and 3rd party messaging providers (use another company's product as the provider).
For more information, refer to Introduction: Messaging resources.
Environment settings help handle requests among web applications, web containers, and the full profile.
Virtual hosts. A virtual host is a configuration enabling a single host to resemble multiple logical hosts. Each virtual host has a logical name and a list of one or more DNS aliases by which it is known. A DNS alias is the TCP/IP host name and port number that are used to request the servlet, for example: hostname:80. The DNS alias might be the host name and port of a web server that routes to the application server or the actual host name and port on which the application server is listening. Java Platform, Enterprise Edition (Java EE) web modules are mapped to a virtual host at installation time. Web modules that use the same virtual host can dispatch to resources within one another.
For more information, refer to Virtual hosts.
WebSphere variables. Variables are used to control settings and properties relating to the server environment. WebSphere variables are used to configure product path names such as JAVA_HOME, and environmental customization values.
For more information, refer to WebSphere variables.
Shared libraries. Shared libraries are files used by multiple applications. You can define a shared library at the node or server level. You can then associate the library to an application or server in order for the classes represented by the shared library to be loaded in either a server-wide or application-specific class loader.
For more information, refer to Managing shared libraries.
Administrative console. The administrative console is a full profile graphical interface that provides many features to guide you through deployment and systems administration tasks. Use it to explore available management options.
For more introduction, refer to Introduction: Administrative console.
Scripting client (wsadmin). The WebSphere administrative (wsadmin) scripting program is a powerful, non-graphical command interpreter environment enabling you to run administrative operations in a scripting language. You can also submit scripting language programs to run. The wsadmin tool is intended for production environments and unattended operations.
For more introduction, refer to Introduction: Administrative scripting (wsadmin).
Administrative programs (Java Management Extensions). The product supports a Java programming interface for developing administrative programs. All of the administrative tools that are supplied with the product are written according to the API, which is based on the industry standard Java Management Extensions (JMX) specification.
For more introduction, refer to Introduction: Administrative programs.
Command line tools. Command-line tools are simple programs that you run from an operating system command-line prompt to perform specific tasks, as opposed to general purpose administration. Using the tools, you can start and stop application servers, check server status, add or remove nodes, and complete similar tasks.
For more introduction, refer to Introduction: Administrative commands.
Configuration files. Product configuration data resides in XML files that are manipulated by the previously mentioned administrative clients.
For more introduction, refer to Introduction: Administrative configuration data.
Monitoring and tuning
- Performance Monitoring Infrastructure (PMI) for monitoring to understand overall system health. For more information, see Performance Monitoring Infrastructure (PMI).
- Request metrics for monitoring to understand resource usage. For more information, see Why use request metrics?.
- Tivoli® Performance Viewer (TPV) for viewing the performance data that you collected. For more information, see Why use Tivoli Performance Viewer?.
Tuning tools. Tuning the product helps you obtain the best performance from your website. Tuning the product involves analyzing performance data and determining the optimal server configuration. This determination requires considerable knowledge about the various components in the application server and their performance characteristics. The performance advisors encapsulate this knowledge, analyze the performance data and provide configuration recommendations to improve the application server performance. Therefore, the performance advisors provide a starting point to the application server tuning process and help you without requiring that you become an expert.
For more information, refer to Obtaining advice from the advisors.
Diagnostic tools. Diagnostic tools help you isolate the source of problems. Many diagnostic tools are available for this product.
For more information, refer to Working with troubleshooting tools.
Support and self-help IBM Support can assist in deciphering the output of diagnostic tools. Refer to the WebSphere Application Server Technical Support website for current information on known problems and their resolution. Documents at this site can save you time gathering information that is needed to resolve a problem.
