Follow these shortcuts to get started quickly with popular tasks. Planning for performance
How well a website performs while receiving heavy user traffic is an essential factor in the overall success of an organization. This section provides online resources that you can consult to ensure that your site performs well under pressure.Queuing network
WebSphere Application Server contains interrelated components that must be harmoniously tuned to support the custom needs of your end-to-end e-business application. These adjustments help the system achieve maximum throughput while maintaining the overall stability of the system.Taking advantage of performance functions
This topic highlights a few main ways you can improve performance through a combination of product features and application development considerations.Obtaining advice from the advisors
Advisors provide a variety of recommendations that help improve the performance of your application server.Tuning the application serving environment
Use this topic to understand the benefits of tuning for optimal performance. Learn about the tunable parameters of the major WebSphere Application Server components and how these parameters affect performance.Troubleshooting performance problems
This topic illustrates that solving a performance problem is an iterative process and shows how to troubleshoot performance problems.Tuning application profiling
This page provides a starting point for finding information about application profiling, a WebSphere extension for defining strategies to dynamically control concurrency, prefetch, and read-ahead.Tuning client applications
This page provides a starting point for finding information about application clients and client applications. Application clients provide a framework on which application code runs, so that your client applications can access information on the application server.Tuning data access resources
This page provides a starting point for finding information about data access. Various enterprise information systems (EIS) use different methods for storing data. These backend data stores might be relational databases, procedural transaction programs, or object-oriented databases.Tuning EJB applications
This page provides a starting point for finding information about enterprise beans.Tuning messaging resources
This page provides a starting point for finding information about the use of asynchronous messaging resources for enterprise applications with WebSphere Application Server.Tuning Object Request Broker (ORB)
This page provides a starting point for finding information about the Object Request Broker (ORB). The product uses an ORB to manage communication between client applications and server applications as well as among product components. These Java™ Platform, Enterprise Edition (Java EE) standard services are relevant to the ORB: Remote Method Invocation/Internet Inter-ORB Protocol (RMI/IIOP) and Java Interface Definition Language (Java IDL).Tuning service integration
This page provides a starting point for finding information about service integration.Tuning security
This page provides a starting point for finding information about how to maintain, improve and harden your security configurations.Tuning Session Initiation Protocol (SIP) applications
This page provides a starting point for finding information about SIP applications, which are Java programs that use at least one Session Initiation Protocol (SIP) servlet written to the JSR 116 specification.Tuning transactions
This page provides a starting point for finding information about Java Transaction API (JTA) support. Applications running on the server can use transactions to coordinate multiple updates to resources as one unit of work, such that all or none of the updates are made permanent.Tuning web applications
This page provides a starting point for finding information about web applications, which are comprised of one or more related files that you can manage as a unit, including:Tuning web services
This page provides a starting point for finding information about web services.Tuning work area
