Thread pool settings



Search Tips   |   Advanced Search


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 transport channels or 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.

Configuration tab


The name of the thread pool to create. The name must be unique within the server.

Data type String


A text description of the thread pool.

Data type String

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

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.

Note: The administrative console does not allow you to set the inactivity timeout to a negative number. To do this modify the value directly in the server.xml file.

Data type Integer
Units Milliseconds
Default 3500

Allow thread allocation beyond maximum thread size

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

Data type Boolean
Default Not enabled (false)
