Using the EAServer Thread Manager
The Thread Manager is a built-in EAServer component
that allows you to run EAServer component
instances in threads that execute independently of client method
invocations. You can use threads spawned by the Thread Manager to perform
any processing that must occur asynchronously with respect to user interaction.
For example, you might have a component method that begins
a lengthy file indexing operation. The method could call the Thread
Manager to start the processing in a new thread, then return immediately.
Since each instance of a PowerBuilder component executes in
its own session, and each session can support only one thread of
execution, you cannot develop a service that can be stopped or refreshed
without using the Thread Manager. In the service’s start or run method,
spawn threads that do the service’s processing. In the
service’s stop method, call the Thread
Manager stop method to halt the threads.
For a more complete description of the Thread Manager, see
the EAServer documentation.
