Object Request Broker thread pool

The Object Request Broker (ORB) is a service that handles requests from clients over the Remote Method Invocation/Internet Inter-ORB Protocol (RMI/IIOP). One part of the workload driver connects to the workload application using its Enterprise Java™ Beans (EJBs) with Remote Method Invocation of Java methods (RMI) using RMI/IIOP.

The ORB thread pool values are adapted to the expected amount of RMI/IIOP traffic. Figure 1 displays the setting for the ORB thread pool. These are the selected settings:
  • The size of the ORB pool is set to 15 for the minimum and maximum number of threads.
  • The thread inactivity timeout is set to 3500 milliseconds.
