WildFly 11.0 Model Reference

  1. WildFly 11.0
  2. subsystem=ejb3
  3. strict-max-bean-instance-pool

A bean instance pool with a strict upper limit

Attributes (4)

  • derive-size Specifies if and what the max pool size should be derived from. An undefined value (or the deprecated value 'none' which is converted to undefined) indicates that the explicit value of max-pool-size should be used. A value of 'from-worker-pools' indicates that the max pool size should be derived from the size of the total threads for all worker pools configured on the system. A value of 'from-cpu-count' indicates that the max pool size should be derived from the total number of processors available on the system. Note that the computation isn't a 1:1 mapping, the values may or may not be augmented by other factors.
