Thread Manager

This manager supplies the threads in which SAPJ2EE Engine system operations are executed. It provides a set of properties for starting and managing system threads.

The Thread Manager runs on both server processes and dispatchers.

Dispatcher

Property	Description	Default Value
InitialThreadCount	The initial size of the thread pool. Specifies how many threads are started at the ThreadManager initialization. After startup, each thread is put in a `waitQueue` , until there is a `Runnableobject` for processing.	100
MaxRQSize	The maximum size of the request queue. It is used to avoid infinite wait.	5000
MaxThreadCount	The maximum number of threads that the Thread Manager will manage. This limit is needed to avoid overload due to too many running threads.	200
MinThreadCount	Absolute minimum number of the threads in the Thread Manager's pool. Even if the J2EE Engine has absolutely no requests, this is the minimum number of threads that will be kept running.	50
ThreadsIdleTimeout	A timeout (in minutes) for which the idle thread exists if a thread has not managed to obtain a task for processing and if the total number of threads is in the [MinThreadCount; MaxThreadCount] range. For more information, see Dynamic Allocation/Reallocation of Resources (in the Administration Manual).	5
