Background documentation ApplicationThread Manager Locate the document in its SAP Library structure

This manager supplies the threads in which client applications’ source code is executed. It provides a set of properties for starting and managing client threads in the Java Virtual Machine.

This manager runs on servers only.

Server

Property

Description

Default Value

InitialFOQSize

The Action Object Stack initial size. It is a structure for reusing the ActionObject objects.

200

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.

40

MaxFOQSize

The maximum size of the Action Object Stack.

5000

MaintainWakeupTimeout

This property defines the time interval through which the thread that takes care of the Thread Managers consistency and is also used for starting “other types” of threads (application -> system and system -> application), is waking up.

5 (min )

MaxRQSize

The maximum size of the request queue. It is used to avoid waiting infinitely.

5000

MaxThreadCount

The maximum number of threads that the Thread Manager will manage. This limit is required to avoid overloading caused by too many running threads.

40

MinThreadCount

Absolute minimum number of the threads in the Thread Manager’s Pool. Even if the J2EE Engine has no requests at all, this is the minimum number of threads that will be kept running.

40

ThreadsIdleTimeout

Defines the time for which the thread waits to take a request for procession. If during this time limit no request comes, the thread is released.

If you increase the value of this property, this leads to an indirect turn off of the Thread Manager’s downsize.

5 (min)
