In WebLogic 4.51 and 5.x, what is the weblogic.system.executeThreadCount used for? What is its maximum and recommended value(s)?

Robert Castaneda

The weblogic.system.executeThreadCount property is used to configure the number of execute threads inside the execute thread pool that service requests made to the WebLogic server. The maximum value for this parameter is operating system dependent and recommended setting will vary upon your application behavior.

A general strategy for determining the optimal value for your system is to monitor your CPU utilization whilst running a test application.
If the WebLogic server is not responding to requests made from a client, and the CPU utilization is not at least 75% +, then you should increase the value and re-run the test.
