Chapter 1 Introducing Jaguar CTS

Asynchronous processing support

Most server processing is driven by client interaction. However, some tasks are best performed asynchronously. For example, you may need to maintain copies of cached data retrieved from a slower source, update search indexes on a regular schedule, or perform lengthy calculations. Jaguar provides two vehicles to support asynchronous processing:

Service components can be used for processing that must run continuously for the life of the server process, or must be performed once each time the server is started. Service components run in a thread that is started when the server starts. See Chapter 33, "Creating Service Components" for more information.
The Jaguar thread manager allows you to run threads at any time. Threads started by the thread manager execute independently of the client or component that starts them, and can be configured to run once or peridiodically at regular intervals. See Chapter 32, "Using the Thread Manager" for more information.
