WildFly 10.0 Model Reference

  1. WildFly 10.0
  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. A value of 'none', the default, 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.
