Thread pool settings

Use this page to configure a group of threads that an application server uses. Requests are sent to the server through any of the HTTP transports. A thread pool enables components of the server to reuse threads to eliminate the need to create new threads at run time. Creating new threads expends time and resources.

To view this administrative console page, click Servers > Manage Application Servers > server_name > ORB Service > Thread Pool. (You can reach this page through more than one navigational route.)

Configuration tab

Minimum size

Specifies the minimum number of threads to allow in the pool.

Data type	Integer
Default	10

Maximum size

Specifies the maximum number of threads to allow in the pool.

If your Tivoli Performance Viewer shows the Percent Maxed metric to remain consistently in the double digits, consider increasing the Maximum size. The Percent Maxed metric indicates the amount of time that the configured threads are used. If there are several simultaneous clients connecting to the server-side ORB, increase the size to support up to 1000 clients.

Data type	Integer
Default	50
Recommended	50 (25 on Linux systems)

Thread inactivity timeout

Specifies the number of milliseconds of inactivity that should elapse before a thread is reclaimed. A value of 0 indicates not to wait and a negative value (less than 0) means to wait forever.

Data type	Integer
Units	Milliseconds
Default	3500

Growable thread pool

Specifies whether the number of threads can increase beyond the maximum size configured for the thread pool.

Data type	Boolean
Default	Not enabled (false)
Range	Valid values are Allow thread allocation beyond maximum thread size or Not enabled.
